2015 Infiniti Q50

DIRECT ADAPTIVE STEERING EXPERIENCEING AT START UP ALTERING THE VEHICLES STEERING AND RESPONSIVENESS AND TURNING RADIUS DOES NOT WORK AND IS INCREASING THE RISK OF A CRASH. VERY UNSAFE TO DRIVE. THERE IS A RECALL 16V430000 ON THIS VERY PROBLEM. HAVE BEEN TOLD BY DEALERSHIP AND NISSAN MOTORS THAT MY CAR IS NOT ON THE RECALL AND I WILL HAVE TO PAY MY SELF TO GET FIXED AND TO SEE IF THAT IS THE PROBLEM. READING THE NHTSA CAMPAIGN NUMBER:16V430000 THIS IS THE EXACT PROBLEM WITH THE DIRECT ADAPTIVE STEERING SYSTEM ON THIS CAR. I BELIEVE THIS SHOULD BE COVERED BY THE RECALL!

While driving my 2015 Infiniti Q50s, the transmission suddenly suffered a catastrophic electronic failure, causing the vehicle to immediately drop into "limp mode." This resulted in a sudden and dangerous loss of acceleration while operating in traffic. A diagnostic scan revealed trouble codes P0500 and P0720 (Output Speed Sensor circuit). However, following Infiniti's official Technical Service Bulletin (TSB ITB19-040), the actual failure was the Transmission Control Module (TCM), which is permanently integrated into the transmission control valve body inside the transmission. Because the speed sensor cannot be replaced independently of the integrated module, I was forced to pay out-of-pocket to replace the entire transmission control valve body assembly and have a dealership program the new unit. This is a widely documented, premature failure on this vehicle platform that creates an immediate highway safety hazard when the vehicle drops power without warning.

DAS issue that I have been dealing with for two months now, issue is still not resolved even after taking out a personal loan for 6k to fix the modules at Douglas Infiniti, waited weeks for the modules, they replaced the modules, did the calibration but a new issue is happening where I'm losing control for a split second and the car would either pull to the left or right egregiously. I took it to back to Douglas Infiniti for the issue, they found code C13E9-00, cleared the code and did the calibration again only for the issue to happen again once I was close to getting home. Spoke with Martin the advisor and he is saying that he thinks its an issue with the rack and pinion and not a software issue. I bought the rack and pinion from infiniti's wholesale direct website, the rack and pinion came from Infiniti of Winston Salem, so it's an OEM rack and pinion, he said I should take it back to the shop where I got it installed and have them check their work, even though they were able to calibrate the system once the new modules were installed, certify their work and give me back to the keys to the car only for the issue to happen again. Took it back to DriveWorks Auto Center in Union, NJ and they couldn't find any issue with the rack & pinion, said I need a wheel alignment thought, went and got a wheel alignment. Driving home from work yesterday on [XXX] going down the hill and the car steering went out momentarily and the car started pulling to the right, straightened the wheel and now I was swaying to the right.

The valve body on these cars are useless. Driving down a highway and cant shift out of 3rd gear almost had a car re-end me. Today I am driving and the ECU is not responding I see the check engine light on then I'm like not again. This would be the 3rd valve body I replaced. First I replaced the whole transmission thinking that is what I needed and advised that the valve body and the transmission are one. Yet no they come in parts. Anyways today I am waiting to get home, but the car is not reading my key fob why? Then the ECU and code U0100 is popping up. Something new and turns the car off. The shifting that happen earlier was just a light bulb of I already knew what is wrong. I felt the car shift with a hunch so I looked at my dash board and saw the check engine light again and was like not again. Please not again. Now on the dash board I see AWD and chassis issue. Then online I am told electrical problem and or ECU module not reading correctly. Like what is up with these push to starts. They are becoming a headache. I need to know just why I am replacing my valve body now for the 4th time???? This all can cause an accident that my car randomly slows down.

The transmission speed sensor has failed needs a new valve body. It seems like a very common problem with this car and it’s a $3000 fix according to my mechanic. I think there needs to be a recall issued considering everybody on this website is reporting the same problems.

The contact owns a 2015 Infiniti Q50. While driving at various speeds, the transmission was slow to shift. The vehicle failed to properly accelerate while depressing the accelerator pedal, and the check engine warning light remained illuminated. The vehicle was taken to a local transmission mechanic to be diagnosed, and it was determined that the gear ratio and speed sensor inside the transmission valve body were faulty, and that the valve body needed to be replaced. The valve body was replaced, and the failure was repaired; however, one week later, the failure reoccurred. The vehicle was taken back to the mechanic, and it was informed that the transmission needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not contacted. The failure mileage was 99,000.

The door lock of the driver's door is stuck in the locked position and the door cannot be unlocked or opened. It will not unlock using the key fob, nor with the manual control inside the door, nor with the emergency key from outside the car. This could trap an inured driver inside the car in the event of an accident. The car has not yet been inspected by anyone. There was no warning lamps or messages prior to the failure. Earlier that same day the door failed to open while in gear but did so when I shifted to park. As this car was very recently purchased by me and I am still learning about it, I failed to recognize this a symptom of an impending failure. Regardless of that warning, total failure occurred the same day. As a graduate engineer who has worked in engineering related fields for more then 50 years I can recognize that a failure mode such as this is both a health and safety hazard to occupants in the event of an accident and a design defect that should not be allowed to be sold to the general public. Thank you for any consideration you give this complaint.

Was making a left turn when the steering stopped working and the motor lost power, the adaptive steering quit working after approximately 15 mins. I started the car and it was working. Went a half mile made a right turn and it went out again. Shut off the motor tried to start it and could not. 20 mins later it started and has been working since. Dealer couldn't find the problem and wouldn't fix it, they also said that their were no recalls but I know that is not true. Infiniti had a law suit brought against them for the adaptive steering issue. If they fixed it why doesn't it work right.

Transmission valve body failed while driving which caused shifts to be limited. It could have caused an inability to shift at all, which is a safety issue. This issue has been inspected and confirmed by an independent shop. No warning signs were present before the failure. Furthermore, this issue is well known to Infiniti. It’s caused by breakdown of the transmission fluid overtime, causing a reduction in the cooling capacity of the fluid. But Infiniti says that the fluid should be lifetime. This overheating causes the TCM on the valve body to fail. If it failed while I was going at a highway speed I could have been injured.

The car just slowed down super fast on freeway almost got rear ended. It would not go past 3rd gear. Poor acceleration. Could have caused a huge accident. I got it diagnosed and they said it is valve body/speed sensor/tcm and they said this is a COMMON problem for 2015 Q50. I replaced this part 2 years ago and here we go again. Shop diagnosed and said this tcm (transmission control module which is in the transmission) but they have to change whole transmission.

Just over 1 week ago, I was leaving a parking lot and driving back to my home when my car wouldn't accelerate past about ~10-15 miles per hour and wasn't shifting gears. When I took my foot off the gas pedal, the gear just dropped immediately from above third to first gear and the car shook. I first noticed this when already out of the parking lot and pulling off from a median onto the road, with no engine light or other warnings. I quickly pulled into the turn lane where there wasn't traffic and turned the car off and back on. It was the same but luckily I was in eyes view of my apartment, so I drove under 10 mph and made it home. I took the vehicle to a transmission service center and the error code that came up on the computer was (P0500 - Vehicle Speed Sensor A), which the service center said is an issue with the "valve body" inside the transmission, specifically the "TCM - Transmission Control Module" that sits on top of the valve body. I contacted multiple Infiniti service centers and they all confirmed that the valve body for my vehicle (part# 31705-x133a) is back ordered by over a month and could be longer until they have it. They do not sell the Transmission Control Module separately. The valve body was quoted to me for $2200 for the part alone. I attempted to install an aftermarket valve body and a new error code came up on the computer (PO720 - Output Speed Sensor Circuit). I kept the original valve body and will hold onto it. Doing some more research, this appears to be a common issue with the Infiniti Q50 - [XXX] In addition to the reddit thread above, a quick google search for Infiniti Error codes P0500 and PO720 point to multiple sources indicating the same common experience and outcome. My vehicle has 110k miles and users in the reddit comments are also reporting the same issue with the TCM Transmission Control Module occurring between 85k - 100k miles in all cases.

Attached is the service bulleting stating they know this will happen and when it does here's how to fix it. Yet they have never recalled the defective transmission. When I contact Infiniti consumer affairs they simply say that they cannot help me because the vehicle does not have warranty.

While driving on the interstate and coming over an overpass there was unavoidable debris located in the road. Immediately after passing over the debris there was a loud noise followed by jerking and the RPM's revved up almost like the car was in neutral. I let up off of the accelerator and then tried to accelerate again. The car would not go faster than 30mph and will not shift out of 3rd gear. I had the car towed to the dealership and the diagnostic codes reflected vehicle speed sensor and there was no physical damage that was visible under the car. I was told that the problem was in the transmission and that it would need to be changed and given an estimate that totaled over $10,000. I was also told by the service advisor that this is a known issue with the Infiniti Q50. After doing researching this a common problem and the consumer is having to pay out of pocket if the warranty has ended. This incident could have ended badly while doing 70mph on the interstate and the car just quits moving. With all of the complaints that I have read over in regards to the transmission issues yet no action has been taken to investigate this problem. It is obliviously a manufacturing issue and the consumer should not have to pay out of pocket for defective transmissions. This luxury car was not a cheap purchase. Very disappointed that with so many cases an investigation has never been done. Infiniti should be held accountable and a recall should be issued for this problem. I will not stop until I can get through to someone that can help.

I received a recall notice (folded information card) from Infinity in the mail in about August 2024 regarding Recall NHTSA 24V-470-R24A7. I also received an email from Infinity on August 28, 2024 with Subject "Your Q50 is due for Important recall repairs " and noted it stated Recall Code R24A7/R24A5: NHTSA 24V-470: Recall Description Q50/Q70 Prop Shaft. I contacted Infinity to schedule the repair and received a confirmed email service appointment for October 4th 2024. When I arrived at the dealership the service department told me they did not have parts but would change my oil and do other service for a fee. All I wanted was the recall fixed. In total I've been to the dealer 3 times and been always told that they have not received parts from the manufacturer. Today I called Infinity Consumer Affairs Department at 1-800-662-6200 and spoke to "Dennis". He did little but talk in circles and did nothing to provide information and when the recall would be fixed. Since I was getting no information and he was not listening or helping I told him I was ending the call and calling the NHTSA, which I did and spoke with Tyronda. Confirmation number for call she gave me is [XXX] for our call. After my repeated efforts and complaints, Infinity appears to have no interest on fixing the vehicle recall they first advised me of in August, only seemingly "going through the motions" as slow as possible. My car is not fixed after about 4 months and they have done nothing to contact me as to when it will be repaired.

Car starts up and a little like the battery is having issues with loss of power. The dash board then shows multiple warning lights such as a batter, steering, and stability control. I turn the car back off and then back on and the steering light stayed on. The steering wheel is stuck but the car still moves forward and backwards with very stiff steering. In the past I had the issue checked by getting the steering wheel fluid exchanged and had multiple alignments since . The car would show signs of stiff steering when parking it will get wonky and like won’t move and bumping into a curb with the rear wheels will trigger it every once in a while.

My braking system completely failed while I was driving with no warning of sound or dash safety indicators. The only way I was able to stop my vehicle is by shifting into park while I was in motion. Two days prior to my car losing all ability to brake, my car was routinely serviced by the local dealership. All check points were green, including my brakes. The dealership towed my car back to the service center to inspect. The diagnostics came back as the break actuator unit (computer sensor) shorted which led to no communication to the brake control assist unit (computer sensor). This loss of communication between these sensors basically caused my brake functions to fail. I was fortunate to have been leaving a parking garage and not on the open road. This could have been a fatal incident. The repairs are $7000 of which Infiniti has only offered to cover $3000. This is a safety issue and a loss of faith with Infiniti as a vehicle manufacturer. There needs to be an investigation so no lives are lost. My vehicle is still not fixed.

After finding a repair shop to look further into the issue I was advised the car needed a new transmission to fix the issue. $4,000+ for the repair and as i google the issue I see that this is a common issue and it seems to always happen unexpectedly side note: also should be a recall on driver side blend door.. i almost died this summer due to cold air only blowing on one side in the middle of summer in 100• degree weather.

My car has 60,000 miles on it and multiple mechanics as well as the Infiniti dealership tell me it needs a new transmission. $8,000. It will not shift above 2nd gear. I took the valve body and manifold out of the transmission and was surprised to find that the output speed sensor plug is actually a dumby plug that connects to nothing. I've had cars with hundreds of thousands of miles on them still driving with the same transmission they were born with. I've rebuilt a lot of engines, but never had to replace a transmission, especially not after 60,000 miles. Any, I searched the internet and noticed that it's a very common problem with this vehicle.

The speed sensor on car seems to have failed unexpectedly while driving over a bridge. The car would barely move and could have become a dangerous situation for multiple people had it been typical traffic. The issue seems to be that although the sensors are corrupted, the entire valve body or transmission must be replaced to solve the issue leaving the car inoperable. The car is currently at a repair shop. The engine light did come on shortly after. PLEASE ISSUE RECALL. https://static.nhtsa.gov/odi/tsbs/2019/MC-10168892-0001.pdf

4/16/2023 Sunday 5pm With my wife and daughter in the car, I started the vehicle in my driveway and selected Sport mode as usual. Selected reverse and backed into our turnaround then forward to the end of our driveway. Driveway is approximately 4 car lengths long with a 20 ft long apron turnaround. Almost immediately after braking at the end of the driveway while waiting for passing traffic to exit drive, vehicle suddenly accelerated and I immediately pressed the brake as hard as I could to prevent driving into passing vehicles. I could hear the tires trying to grip/spin while I was fighting to press the brake harder to hold it t back. I then panicked and selected the gear shifter to anything other than drive and it immediately did the same in reverse. After getting in into park, I immediately selected Standard mode and the vehicle performed normal afterwards. There were no warning lights or anything to indicate any issues. Previously I had noticed minor intermittent issues of high RPMs when slowing or braking while in Sport mode but it would immediately correct itself. I have not had a chance to take it for inspection as it's now Monday morning April 17. We were all very shaken. Please advise.
