My husband was driving our 2018 Chevy Suburban when it suddenly stopped accelerating and he could no longer shift gears. Luckily, this happened while he was driving down a gravel road (approx 25-30mph). If he would have been driving at highway speeds, it is likely that he could have lost control of the vehicle. Our Suburban had no issues to this point and had always run well. We take it in for routine maintenance. We had it towed to a local repair shop, and they informed us that something had happened with the transmission and that it would need to be replaced. I have found several GM transmission recalls and our situation sounds similar to reference N252536750. Again we had no warning signs and had been experiencing no issues with our vehicle. If this had been something that we had been noticing problems and hadn't gotten it looked at, I can understand that maybe this had been something on going for a while that we had just missed maintenance on. However, for the transmission to stop so suddenly, I believe there must be some sort of larger failure in the transmission system.

I am reporting a safety issue involving a Cybex Eternis S child car seat. The seat was manufactured on 02/28/2020 and has a printed expiration date of 02/25/2030, indicating a 10 year usable life. At approximately five years of use, the head impact foam failed and is broken into two separate pieces. The foam pieces are detached. This foam is a required safety component. Cybex customer service confirmed in writing that if the head impact foam is detached or broken into separate pieces, the seat does not meet safety requirements and should not be used. Cybex also confirmed that no replacement part is available and no repair or remedy is offered. As a result, the seat is unsafe and unusable halfway through its stated usable life, with no ability to repair or replace the failed safety component. This raises concerns about product safety support for child restraint systems marketed with extended usable lifespans.

Transmission will not go into drive or reverse. This also happens when car is in drive going down the road it will all of a sudden lose power and not go when pressing gas pedal. Vehicle has to completely shut off several times before it will go back into gear. No warning before it started. This can be dangerous when it happens in traffic and I can’t move car out of the road. It has not been inspected yet. Also blind spot warning does not always says it needs serviced.

I've taken this SUV to the Chevy dealership 4 times now for the same issue. SUV will not start at times then starts, it will even turn off on the road without warning. New Battery and Chevy can not find out issues $500.00 later. The brake pedal becomes hard to push down, and it will not start: wait 10 mins or so and it will start. Even the remote start at times will not work. Chevy has had it for 30 days at a time and I'm being told to bring it back when it happens, how do I that!

Transmission has to be replaced due to transmission slipping and delayed shifting under heat and prolonged highway driving. This issue also causes SUDDEN hard shifting, hard breaking, shaking of the steering wheel, along with grinding of gears!! This is a safety issue to to no warning signs at all along with a sudden drop in speed and power!! While driving on the interstate or highway this sudden change can cause the vehicles behind you to rear end you or cause a pile up!!! The driver has no control of vehicle when these issues happen!! A loss in control due to shaking of the steering wheel is a huge issue!!! Lack of shifting or hard shifting causes a SUDDEN stop of vehicle with no warning signs while driving!! It is going to cause a crash!!!! These are serious and dangerous issues that Gm will NOT do a recall for!! GM is aware of the issues due to Suburban, Tahoe and Silverado vehicles in the year models 2018-2023 having this reoccurring issue!!! I recall needs to be done to save someone’s life!!!!! I have only had my suburban for 8 months!! I was not made aware of this issue at all!!!!!! This also causes rough idle!!!!!!!!

No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

Dear NHTSA, I am submitting this complaint to report a recurring and potentially dangerous issue with the transmission in my 2018 Chevrolet Suburban, which I purchased brand new in 2018. At approximately 60,000 miles, I experienced severe transmission issues that led to a complete transmission replacement. Now, at around 133,000 miles, I am encountering the same symptoms once again. The transmission makes a loud clunking noise during acceleration and braking, and shifts gears abruptly and harshly. These symptoms appeared suddenly, with no warning lights or prior alerts. This problem poses a significant safety concern. The vehicle sometimes struggles to accelerate properly, making it dangerous to merge into traffic. Additionally, the forceful shifting makes the vehicle feel unstable and unpredictable, as though something beneath the car might fail while in motion. I transport my husband and our children in this vehicle, and this issue puts all of us at serious risk. I have scheduled another appointment with a GM dealership to inspect the vehicle. However, given that this is a recurring failure involving a critical system, I am requesting that NHTSA investigate this matter as a potential defect affecting other owners of the same model. Thank you for your attention to this serious concern.

My Suburban is having the same issues as the most recent recall on the 2021-2025 Chevrolets. The issue is with pretty much all of the motors that go from the V8 to the 4 cylinders. It's doing the same exact thing a friend of mine's 2019 Tahoe did. It's making a loud knocking/ticking noise. When you first get to going it starts almost sputtering which can cause issues if you're in oncoming traffic trying to cross roads.

Currently own a 2018 Chevy Suburban with a lifter issue in the engine. This is a known issue with Chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in Regal Chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and Chevy has done nothing to help support loyal customers.

Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.

Car abruptly lost power while driving causing rapid deceleration and requiring immediate action to steer vehicle off the active roadway without hitting other vehicles or causing property damage. There were no warning lights or signs until this occured. The vehicle was later towed to chevrolet who informed us that this was a KNOWN ISSUE these cars have where their "lifters fail and sometimes even damage the camshafts" If this was a known issue why would it not have been addressed in a recall. After speaking with the dealer I searched the internet for the same issue and it is widespread across several GM cars including mine. GM now wants $3,100 to repair a dangerous manufacturer defect.

The second row - driver's side seat belt no longer was retracting, making the seat unsafe. This belt had been slow to retract since we purchased this vehicle from the dealership in June 2022, but it stopped retracting in mid January 2023. As my extended warranty only covers drive chain, the dealer charged me $627.43 for parts and labor to replace the seat belt. It is disappointing that Chevrolet does not warranty the basic safety equipment for the life of the vehicle.

Vehicle started shaking while accelerating. Independent mechanic and his recommended transmission shop diagnosed an issue with the transmission - specifically the torque converter. Shop said the car was unsafe to drive while waiting for new transmission as it could lose ability to accelerate while driving. When I asked the transmission shop if they felt the previous owner(s) may have abused the car with their driving to cause the issue at a relatively low mileage, they said this was a systemic issue with this vehicle. In fact one of the repair techs had the exact same issue with his personal vehicle at similar mileage (same make / model).

On approximately December 23, 2022, I notice that the UV protection coating on the hood and roof of my SUV is no longer protecting these areas of my vehicle. Which I am now concerned could lead to rusting on my 2018 SUV. I reported this issue after seeing many complaints on the WEB for the same problem by vehicle owners. A Chevrolet dealer mechanic also informed me of customers voicing my concern about the UV-protecting coating issue. I'm worried this issue will continue and affect the painting of my entire vehicle.

General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Remedy: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 18315.

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
