Per Acura service bulletin 23-022, Dated June 9th 2023, Acura extended a warranty on the rear steering actuators that were admitted to be “manufacturer error” parts, to extend 10 years from purchase date. In my opinion any part that is known to have manufacturer defects that effect the primary Rear wheel drive system that effects almost all safety systems on the vehicle to include limp mode on a highway needs to be replaced, this is a large safety issue. Fact; Honda admits manufacturers errors on parts. Fact; Honda recognizes the issue and issues a service bulletin. Fact; Honda extends the duration to repair the manufacturing defective part. Fact; Honda denies claims ( even when vehicle safety is a concern) after the 10 year deadline Fact; most average 2014 cars driven 12,500 miles per year have roughly 125,000 miles in 10 years and the manufacturer error was realized most likely due to usage. My 2014 now 12 years old has just recently realized the manufacturer error at 81,000 miles and Honda will not honor repairs for their errors. Facts; Google; “is it safe to drive my Acura RLX with a defective Precision all wheel steering actuator”…safety concerns realized. Facts; NHTSA is in place to keep the consumers safe and the manufacturers held accountable for repairs, let’s face it the service bulletin is just a way for manufacturers to appear proactive while turning out defective unsafe parts.

I purchased a 2014 Acura RLX. It had a LKAS Problem warning when purchased. I thought that meant that feature would be disabled. No big deal. In stead I have experienced the car making abrupt jerks to the right on multiple occasions. One instance, I turned onto an on-ramp that was dual lane. There was a vehicle to the right of me and my car abruptly jerked to the right towards the other car. I was able to slow a bit before entering the interstate traffic to gain control. Another instance, I turned left onto a county road. Upon straighten my steering wheel the car made another sudden jerk to the right with my steering wheel still partially turned to the left, and several warning lights and message started appearing, including: Brake system problem, adaptive cruise control problem, brake hold system problem, power steering system problem, and vehicle stability assist problem. I have noticed a rubbing sound coming from the rear end at times when turning. There have been 3 other instances where the car was jerked to the right with no additional warning lights or warning. Luckily those times there were no other vehicles nearby and I was moving at a slower speed allowing me to be able to slow down and correct the issue. The vehicle has not been inspected yet. The vehicle has an appointment with the dealership in the next 24 hours. It is available for inspection upon request. This is a serious safety issue! My teenage kids are not safe to drive this vehicle! The vehicle is in excellent structural condition and the motor runs excellent. It sounds like the RTC actuators is a huge issue!

Went into limp mode on a highway in heavy traffic, car began to break rapidly decreasing in speed and would not accelerate at all. All dashboard lights came on and a CMBS notification came on. I and my family were almost rear ended by several vehicles. I am terrified to drive the vehicle and immediately pulled over to the side of the road and had vehicle towed. Also, while driving vehicle, steering wheel will randomly jerk hard to the left causing vehicle to swerve left. I Have contacted the Acura dealership and am being denied the recall.

The PAWS (Precision All Wheel Steering) has major issues where the system either activates suddenly when driving the vehicle, regardless of slow speeds, high speeds, going straight or turning and the back wheels suddenly turn causing the rear end to slide out. I took the vehicle to my local dealership and they said it is a known problem with this vehicle rear toe actuators and Honda has issued a warranty extension for 2013-2019 RLX to correct it. Unfortunately, this vehicle is no longer under that warranty and the only way it can be corrected is a $6800 replacement. Honda (Acura) obviously knows this is an issue but the severity is being majorly downplayed, as losing steering of a vehicle seems pretty serious to me! The vehicle cycles through multiple warning lights immediately upon the issue occurring, not before.

The rear tires P-AWS actuators cause the rear wheels to slide sideways causing lose of vehicle control with out warning. There is no rhyme or reason to the loss or when to know its coming. The cars are a ticking time bomb. Upon researching this problem, it seems I'm not the only one having issues with this. It needs to be put on the manufacturer to repair issues with this if there are that many of these cars out there with this issue. It's going to get someone killed.

The vehicle is equipped with rear wheel steering which is executed through a toe actuator device in the suspension attached to each rear wheel. The actuators are malfunctioning on my vehicle, causing it to swerve while driving on multiple occasions. The vehicle swerved in a fashion taking it out it its lane and could easily have put the vehicle into oncoming traffic with zero steering input from the driver. This is a very serious safety issue and vehicles with this equipment should be recalled for repair in my opinion. Acura is aware of the problem and did extend the warranties on the vehicles to cover the issue, but the extension ended in 2024. I spoke with Acura customer service at their US headquarters in Torrance, CA and their response was that they no longer cover this repair but acknowledge that it is a serious safety concern with the vehicle. My local Acura dealer charges approximately $7,000 to repair the problem and I will attach the estimate.

I have a serious safety issue with my 2014 Acura RLX. While driving, the rear wheel intermittently kicks out, causing the entire vehicle to swerve unpredictably. This poses a significant safety risk to myself, passengers, and other road users. The rear wheel kicks out, leading to sudden swerving of the vehicle. I believe this is related the the Rear Toe Actuators and PAW-S system. I first noticed this issue in July 2023 and sought assistance from Acura. At first the dealership denied that my car was affected by their Service Bulletin 23-022. I knew I had an issue and called and created a case with Acura. I drove my car as little as possible last year. Last month, I had an issue which made my car only drive under 50mph and all these lights popped up on my instrument panel: it read: Vehicle Stability Assist (VSA) problem, Forward collision warning (FCW) Electric Power steering problem, Brake. I brought my car in to my regular mechanic. He showed me the codes on my car showed the service bulletin. I then took my car back to Acura dealership (June 17th). Acura identified the issue as related to rear toe actuators. Acura called me and informed me that I was outside of their warranty period even thought I started the case with them last year. The estimated cost exceeds $3,000, which I find financially burdensome. The safety issue persists despite Acura's negligence and puts me and my family and other drivers at risk, necessitating urgent intervention to prevent potential accidents. Service Bulletins: Reference to Acura Service Bulletin 23-022 addressing similar issues. Communication with Acura/Honda: Case numbers: Case 14025611 Please help me in investigating this safety issue and determining if it warrants further action, such as a safety recall or investigation into Acura's handling of the matter. I believe this issue may affect other owners of the 2014 Acura RLX or other RLX owners up to the year 2020 and poses a safety risk that requires immediate attention.

After making a turn at light, steering wheel stayed turned while car was straight. Then it jerks itself back into place. Another occurrence was while driving on highway, steering wheel was turning sideways while driving straight then car starts to slow down on its own and the lights on dash came on ( breaking system, fwd collision, lane departure, brake hold system,VSA, EPS, hill start assist) this has happened 3 times in the last 2-3 months. We have changed tires, had alignment done, had fuses replaced, new battery and it is still happening. Not safe while driving on highway or anywhere for that matter. Needs to be recalled and fixed. I have looked up this issue and it seems to be an ongoing issue on this year/make/model. I cannot be driving in a car like this if it keeps happening, I drive my elderly mother and in-laws to their doctor appointments and cannot risk an accident with them. It happened once with my in- laws in the car. Could be a serious lawsuit on Acura. The consumer stated that all of the issues started around the same time.

The car, unexpectedly fishtails while driving straight.This has happened since I purchased the car and it is EXTREMELY DANGEROUS as it can thrust the car into oncoming traffic. The service technicians can never duplicate the problem. The problem, according to the dealer is the PAWS system rear wheel steer and it is a very well known problem with the 2014 RLX. The dealer told me that the PAWS system parts are no longer made and if they were, they would cost $2800.00 each side, plus labor. Honda Acura must recall and correct this problem before it kills someone. At the very least figure out how to disable the system so it can’t steer on its own. There WILL BE traffic fatalities if this issue isn’t corrected, it’s just a matter of time.

Today after I pulled out of work, the car fishtailed when I was entering the highway. All the warning lights started flashing-paws, brake assist,power steering, hill,lane departure,etc. 2. This is very dangerous and a safety issue that Acura should take responsibility for before accidents occur! 3. I notified the dealer on 5-13-2022 who stated the problem was probably just battery voltage related. 4. No warnings with the dashboard flashing lights until 5-13-2022 but the sudden fishtailing has been occurring for several months now. 5. I assumed it was the tires and bought 4 new ones. On 5-15-2022 the car fishtailed so suddenly my passangers thought i was trying to avoid hitting something in the road.

The steering ability and rear suspension failed on the vehicle. I was driving straight on a major interstate and the car veered to the right. I was able to correct the vehicle by turning the steering wheel to the left. This happened on several occasions during this particular weekend. However, 2 weeks prior to this incident, I received forward collision warnings, brake warnings, and lane departure warnings. I researched this issue online and it said it could possibly be a defective battery which I had recently replaced. The battery never failed. The warnings only happened for 2 days. Then the car started started fishtailing 2 weeks afterwards. I took the car into the dealership and the diagnosis was rear actuators which had been replaced 2 years prior. The cost of the repair is $4600. I informed them this is a safety issue and could cause harm to me or someone else. However, they refuse to take responsibility for the rear suspension issue.

The component that failed is the left and right PAWS steering actuators. My car has 66,000 miles. At 25,000 miles, these parts were replaced by the dealer. Now at 66,000 miles, the parts are again failing. The car is unsafe to drive because the failure of these parts cause the rear wheels to "fishtail." It has happened to me 3 times this month and then I brought the car into the dealer. Although it didn't cause an accident, it certainly is easy to see how this loss of steering control would cause an accident. The dealer has confirmed the parts need replacing. There were no warning lamps, messages or other symptoms prior to the failure.

Steering abruptly turns rear wheels when car is going straight, usually after a turn. This has happened multiple times when driving at moderate speeds over the last year or so. I thought it was the tires, so I got new tires and it is still happening. It is very scary and now I'm afraid to drive my car on the interstate at high speeds. I believe that this is a serious safety issue and consumers are not being treated fairly by Acura. In my opinion, this is an unsafe vehicle and should be recalled. If unstable abrupt steering of the rear wheels were to occur at high speed in traffic or along winding 2 lane roads, someone could be seriously injured or killed.

As of June 2021... Experiencing the same issues as everyone else. Purchased the 2014 model in 2015 and while it is paid off and out of warranty, the power all wheel steering (paws) feature malfunctions while driving at various speeds. The rear wheels would erroneously turn and caused the vehicle to suddenly jerk and fishtail. Technicians at the Mac Churchill - Fort Worth dealership always told me that they were unable to diagnose/duplicate the problem. While under warranty, I took the car to the dealership and reported the car making loud noises when steering, informing them that a moaning/rubbing noise could be heard from the car's rear when driving straight...again, I was told by the techs that they couldn't duplicate the problem. Made a call to Acura customer care 800 number on June 4, 2019 to report this same issue and received no resolution. The car is well out of warranty and all of the issues are happening quite frequently. Was traveling on hwy 45 headed back to DFW area. The posted speed limit is 75 mph. All the warning lights started flashing-paws, brake assist, power steering, hill, lane departure, etc. The power to engine was cut, thus slowing the car down, steering wheel alignment was off. This was VERY scary and of course, prompted me to just take it to an independent mechanic. The mechanic made me aware that they were unable to get parts to fix the problem and that their is an ongoing class action lawsuit regarding this issue. Called Acura customer care 800 # again and rep stated there is no known class action lawsuit related to my VIN #. I'm not sure what else to do about this issue. Acura should be held liable and fix this recall before someone gets seriously hurt.

The rear wheel steering system (P-AWS) causes the rear end to suddenly swing out of the traffic lane after making a turn. This has happened several times and since there is no way for the driver to control the rear wheel steering it is very difficult to avoid colliding with surrounding or oncoming traffic. I have contacted the dealer and they seem to have no idea as to what the cause could be or how to fix it as there are no warning indications.

Investigations

2 NHTSA investigations on record

Investigations are agency reviews, not findings that a vehicle is defective.

Desiccated Air Bag Inflator Rupture

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

Electrical overstress

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect.  During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.  The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications.  The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU.  In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment.  FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle.  Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW.  These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes.  An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time.   In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU.  This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners.  Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW.  The risk associated with the ASIC is equally shared among all OEMS involved in the investigation.  The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage.  There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation.  The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU.  If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC.  Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC.  All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled.  In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024.  With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
