POWER TRAIN, UNKNOWN OR OTHER
COMPONENT: The 10-speed automatic transmission failed on 6/29/26, locking the vehicle completely in neutral. The neutral override could not be disengaged even by dealership technicians. Vehicle is currently at [XXX] Chevrolet, [XXX] and is available for inspection. SAFETY RISK: I have 3 young children who are regular passengers. The failure occurred without warning. Had it happened at highway speed in oncoming traffic, I would have had no ability to move the car — creating a direct risk of a serious or fatal collision. CONFIRMED BY DEALER: Yes. Don Hewlett Chevrolet received the vehicle on 6/30/26 and confirmed the failure is directly related to two active federal recalls: NHTSA #24V-797 (10-speed transmission valve body failure/wheel lockup) and NHTSA #22V-036 (driveshaft assembly/loss of propulsion). Vehicle has been unrepaired for 13 days with no timeline provided. OTHER INSPECTIONS: Vehicle has been in possession of Don Hewlett Chevrolet since 6/30/26. No manufacturer representative, police, or insurance inspection has occurred. WARNING SIGNS: None. No warning lamps, messages, or symptoms appeared before the failure. The power train locked suddenly and completely without any prior indication on 6/29/26. Despite the dealer confirming this is recall-related, they have indicated I may owe partial repair costs. Under 49 U.S.C. § 30120, GM must remedy recalls at no charge regardless of mileage or warranty. I am requesting NHTSA investigate both the failure and GM's attempt to charge the owner for federally mandated recall repairs.

ENGINE
I had a recall serviced on a Friday which was completed by the dealership. My car sat all weekend and was not driven until Monday AM which was fine. After work, there were several warning lights that popped up and it was making a terrible noise. I was unable to drive home and had to have my car towed to the dealership. Following there inspection, my engine had to be replaced due to a known issue with this engine and GM. Cylinder #2 misfire, lost compression - lifter had spun in guide, camshaft is damaged - engine needs to be replaced. Unfortunately, I was just out of warranty so it was either pay $12,000+ for a new engine or walk away from a car that I love. I just don't understand why if GM knows this is an issue, why there is not some sort of recall on it.

POWER TRAIN
I own a 2022 Chevrolet Suburban with approximately 115,000 miles. While driving, the check engine light illuminated and the vehicle suddenly entered limp mode. The transmission lost normal operation, including reverse gear, significantly limiting the vehicle’s ability to operate. The failure occurred without warning and created a potential safety concern because the vehicle could no longer respond normally to driving conditions. The vehicle was inspected by a Chevrolet dealership, where technicians diagnosed a failed transmission control valve body and confirmed the valve body required replacement. I paid to have the repair completed. After the repair, I learned that GM issued Special Coverage N242454441 for certain 2021-2022 Chevrolet Suburban vehicles equipped with the same transmission. The bulletin describes premature transmission control valve wear that can cause a service engine light, reduced engine performance, harsh shifting, and requires replacement of the transmission control valve body. My vehicle experienced the same failure and required the same repair, but my VIN was not included in the covered population. I contacted GM before authorizing the repair and requested assistance, but my request was denied because my VIN was not included in the special coverage. I am submitting this complaint because my vehicle experienced the same transmission valve body failure identified by GM despite not being included. I request that NHTSA document this failure and determine whether additional vehicles equipped with the same transmission should be included in any current or future safety investigation.

EXTERIOR LIGHTING
2021 SUBURBAN LT. Driver side headlamp adjuster failed while driving. Wife struggles to see at night so when the adjuster failed the driver side headlamp faced right to the ground causing no projected illuminating light. We attempted to adjust the light when she arrived home but it would not adjust due to the leveler failing and breaking. Looking into the matter we found out that numerous people with those, suburban's and even Silverado's that share the same parts have also reported the part failing due to the leveling being so thin and driving over bumpy roads will cause the weight of the lamp to snap and break. Its a growing concern yet dealerships are charging customers over 1400 to replace the whole assembly as it is one seal piece. There was no indication of it starting to fail just the moment it went from fine to facing the ground. We tried to run through extended warranty but claimed denied stating us touching the leveler to adjust it is what caused it to break. We tried to prove our case that doing research they would find to be common but no luck. its a safey matte.r

STRUCTURE:BODY
The sunroof drains continue to fail. I’ve had multiple occasions where the car has had drains back up or be disconnected.. This is a safety issue because it creates mold as water falls in the headliner and then the cabin. It also creates rust, particularly behind the dashboard. That’s not rust proof. Despite being under warranty, the dealers are useless and helping address the issue because it’s la design flaw. The multiple water intrusions also affect the electronics in the vehicle., potentially disabling critical features like airbags and safety systems.

STRUCTURE:BODY
The driver-side front door and related body fit/sealing system appear to be defective. The door is visibly uneven and misaligned with the surrounding body panels, resulting in excessive door gaps and significant air intrusion into the cabin while driving. The condition is available for inspection upon request, and photographs and videos documenting the issue are available. The excessive air intrusion creates substantial wind noise and driver distraction while operating the vehicle at highway speeds. The misaligned door also raises concerns regarding proper door sealing, structural fit, weather protection, and occupant safety in the event of an accident. A vehicle of this age and condition should not exhibit such defects. The condition is consistently reproducible during normal driving, particularly at highway speeds where excessive air enters the cabin through the driver-side door area. (If applicable, add: "The vehicle has been presented to an authorized Chevrolet dealer for inspection.in FH dailey chevrolet San leandro, they replaced weather strip, but air is more then what it was before, they declined my service and told me to take the vehicle where I purchased from in epic chevrolet Sacramento. No vehicle is not inspected by anyone. No warning lamps or diagnostic messages were displayed. The primary symptoms were visibly uneven door alignment, inconsistent door gap measurements, and noticeable air intrusion and wind noise while driving. These symptoms were first observed shortly after taking delivery of the vehicle and have persisted since that time.

ENGINE, ELECTRICAL SYSTEM
The engine of this car has been under recall for multiple issues during the time we have owned it. The most recent issue that was experienced was total engine failure and electrical malfunction while driving on a busy street near train tracks. The vehicle was making a loud banging sound moments before this occurred. I wasn't even given time to get to a safe spot to investigate the issue. When it shut down, a quick message flashed across the dash board--stating ability to shift had been lost (or something to that effect)--the vehicle then flipped into neutral and immediately lost power. My safety was put at great risk due to the fact that the entire vehicle shut down moments after I crossed over a very busy railway track. The vehicle had to be towed to a nearby Chevrolet dealership where it has been confirmed there was total engine failure as well as blown main electrical fuse.

ENGINE, FUEL/PROPULSION SYSTEM
My 2023 Chevrolet Suburban Premier is covered under GM recall 25V-274 for the 6.2L L87 engine defect (loss of propulsion from connecting rod and crankshaft failure). In XXX, the dealer notified me my vehicle required a full engine replacement under this recall. Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days. Approximately 6,000 miles later, on XXX, the replacement engine failed while I was driving on the interstate highway near Billings, Montana. There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer confirmed the vehicle needs a second complete engine replacement under the same recall. This is the second L87 engine failure and second full engine replacement on this vehicle under recall 25V-274. No crash or injuries occurred. I have an open case with GM (#XXX).

2021 Chevy Suburban started to have harsh shifting particularly on acceleration and shuddering at higher rates of speed (feeling like you are driving over a rumble strip). I took it to the dealer, and they confirmed the torque converter was in the process of failing. It's currently in the shop getting a new torque converter. No warning messages/lights had yet appeared. Technician at dealer stated that this was a common failure with this model.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, STEERING
As I was driving 75 mph down the highway my collision alert flashed all my lights turned off, including my headlights and all interior lights as it was dark time and they flashed back on a couple of times until they finally stayed on. I pulled over and as I came to zero, speed, the vehicle completely shut down. It did start back up, but this is not the first time I get a light on my dash that says stability track and then everything resets and I don’t have any lights on at all after that this has been happening off and on I also have three coworkers that have the same make, and year that experienced the same problems ! My situation on the highway was very dangerous. It was pitched dark outside and I lost vision due to my lights going off at 75 mph and my steering wheel also locking up. The next time the vehicle does it I will take a video for proof. I have heard that this problem is very common in these vehicles and believe something should be done because that is a dangerous situation if I was going around a corner and my steering wheel locked up, I could easily flip my car. I have small children that’s why I have the big space but we need safety for our family.

POWER TRAIN
I am writing to formally report a critical safety defect in the vehicle’s transmission system. While driving, the vehicle began experiencing severe vibrations, accompanied by an abnormal increase in engine RPMs, while the vehicle failed to accelerate appropriately. The vehicle became unresponsive, limiting my speed to 15-20 mph. This forced me to make frequent stops every 6-7 minutes to allow the transmission to cool down, as the car would not sustain normal speeds. This failure created an extremely dangerous situation on the highway. Due to the sudden loss of power and inability to maintain traffic flow, I was subjected to aggressive behavior from other drivers, who were honking, gesturing, and clearly endangered by my inability to accelerate. This transmission failure is a major safety hazard that renders the vehicle unreliable and dangerous to operate in any traffic condition. I am requesting an immediate investigation into this transmission defect and a permanent resolution from General Motors, as this issue poses a significant risk of causing a collision. I spoke with the owner of AAMCO, and he showed me that they have 7 of these Chevy Suburbans, GMC Yukons, and Chevy Tahoes, Escalades, and they all have the same problem, the transmission needs to be replaced, and General Motors is not notifying car owners about this problem, but it should.

The vehicle was shaking and shuddering when trying to maintain highway speeds. Would have to slow down to maintain safety. The dealership advised the transmission needs replaced however we are seeing this is a widespread problem that GM has refused to admit fault for.
