SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, ENGINE
To NHTSA, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from Criswell Chevrolet (Gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of Park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 pm: While traveling ~35–39 mph on a five‑lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: All dash lights illuminated (including brake failure and Forward Collison System Unavailable); vehicle stuck in Park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
While driving home late at night, the vehicle experienced a sudden mechanical failure in the engine. I was traveling approximately 2 miles per hour while slowing to stop at a stop sign when there was a loud “clunk,” followed by an abrupt stop of the vehicle. Immediately after this occurred, multiple dashboard warning lights illuminated, and a knocking sound began coming from the engine. The vehicle is currently not operating normally and is available for inspection upon request. This incident occurred late at night while I was driving with my two young children in the vehicle. The sudden and unexpected stop put us at risk of being rear-ended or stranded in an unsafe location. The loss of normal vehicle operation created a dangerous situation, especially given the time of night, location, and the presence of my children. There were no warning lights, messages, or noticeable symptoms prior to the incident. All warning lights illuminated only after the loud clunk and abrupt stop occurred. The knocking sound from the engine began immediately following the failure. I now am in a rental car that costs $700 a week that my insurance doesn’t cover.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Control algorithm issue. Unexpected acceleration. Not confirmed by dealer. I experienced it twice. Google Gemini sems to know about this. No inspections performed. No warnings. There is a safety issue with the 2026 Chevrolet Tahoe adaptive cruise control. My observation: On a previous drive, I used the adaptive cruise control with it set at highway speed. I disengaged it as I got off the highway using the brake pedal and arrived at my destination via city streets. I turned the vehicle off, exited and locked it. Later, I re-entered the vehicle, started it and began slow speed maneuvering (<5mph) in my driveway, where in, I accidentally bumped the cruise control “Resume” switch, at which time the vehicle began to accelerate, unexpectedly. I stepped on the brake to regain control. No accident occurred. This happened a second time upon my return from the local supermarket. In my opinion, the cruise control should return to the OFF mode when the engine is turned off and not remain “On” and ready to “Resume” after the engine has been cycled. The current operating mode is unsafe.

ENGINE
Dealer checked the 6.2L motor for known defects. It "passed" inspection on 11/20/25 and got the thicker oil (OW-40). The engine lost propulsion ("died") 3 times on a 55mph State Highway on 02/09/26 with my 4 year old in the car with me. It died and came to a complete stop in one lane and would not re-start initially with cars almost rear ending us and needing to aggressively swerve to avoid hitting us. After 4 or 5 attempts it started again (making terrible grinding noises) so I could get it off the road before it died again. It started again to drive home on the back roads approximately 1 mile. Low oil pressure and check engine lights came on. I also received notifications from onstar and from the my Chevy app that there were severe motor or transmission problems. I scanned it with an OBD II Scanner and it has code P00016 (Camshaft Position Correlation - Bank 1 Sensor A). It got towed to the dealer and is now confirmed it is in need of a full motor replacement less than 3 months after they told me the motor passed inspection! This is not acceptable. To be told it's fine and then have it fail with my child in the car is extremely unsafe. Now I'm stuck trying to get a comparable loaner vehicle from the dealer to drive in the snow and mountains with my family safely while they expect to have the vehicle at minimum of 6 weeks. So far they have not found a loaner potentially putting my family in further danger by not having a 4X4 vehicle in a snowy climate.

VEHICLE SPEED CONTROL, ENGINE, POWER TRAIN
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving and attempting to slow down to approximately 35 MPH, there was an abnormal clunking sound coming from the vehicle. The contact believed that the sound was caused by ice buildup on the mud flap, but shortly afterwards, the engine revved unexpectedly, with the check engine warning light illuminated, and the message “Reduce Acceleration - Drive with Care” was displayed. The vehicle started to coast unintendedly. The contact stated the vehicle returned to normal operation after a short while. The vehicle was taken to a local dealer to be diagnosed. The mechanics pushed the vehicle out of the parking spot before inspecting the vehicle. The vehicle was diagnosed with transmission valve body failure. The contact was informed that the transmission valve body needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 88,342

ENGINE
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while his wife was driving out of the driveway and driving approximately 20 MPH, the driver became aware of an abnormal flapping sound that became louder as the vehicle accelerated. Additionally, the contact stated while his wife was driving approximately 60-65 MPH on another occasion, the check engine warning light illuminated. The driver pulled over to the side of the road. The vehicle was towed to the residence, where a mobile independent mechanic diagnosed the vehicle with a misfire in cylinder #8. The mechanic determined that both sides of the engine lifters, the gaskets, and other unknown parts needed to be replaced. The vehicle was not repaired due to the cost. The dealer and the manufacturer were not contacted. The vehicle warranty company was contacted and informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 93,000.

SERVICE BRAKES, UNKNOWN OR OTHER
I have a 2024 Tahoe that was purchased new from the dealer and has 13,700mi. The first service was completed as required in December with no issues identified. Less than 2 months later the front wheels started making a squeaking sound intermittently when accelerating, coasting or breaking. There were no warning messages. The dealership/mechanic looked over the car & said that the front brakes were measuring 2mm (completely worn out) but no other issues. Before drop off the car computer said above 75% or more for front and rear breaks (green). I have been driving the car in normal condition in southern ca. It seems that the break pads were defective and degraded at an alarming/unsafe rate or that a different component on the car caused them the continuously rub and wear down. The dealership blamed it on owner operation even though they supposedly checked them 2 months before and didn't see abnormal signs of wear. I am very concerned with the QUALITY, RELIABILITY & SAFETY of the front breaking system due to the fact that the breaks wore out so fast. I am worried that the problem has not been properly identified and that that breaks will continue to have this problem if it wasn't caused by faulty pads. I have never had a break wear problem like this before on any of the other 5 new cars that I have owned. This is the first American brand car I have owned and hopefully it's not a sign of things to come.

SEATS, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
The vehicle has service driver assistance system warning. The seat vibration is not working and I believe there are issues with the sensor and or harness. There have been recalls on previous years of this vehicle for the same thing. There have been a wave of these lately, according to the dealership working on the vehicle. Parts availability is currently low because of this resulting in longer repair times. This is a key safety feature of the vehicle and must be repaired quickly. Unsuspecting users may expect warnings before collisions that may not happen.

POWER TRAIN
2021 tahoe with 3.0L diesel engine and 139k miles recently began overheating when on interstate but temp would jump up quickly then quickly back down. Reduced acceleration mode is triggered and AC is turned off automatically. Diagnostic report shows coolant control valve error code and it was explained to me that valve is sticking then as engine pressure rises, it knocks it loose again explaining the quickly jumps and dips in temp. Fan runs constantly from moment it is started too. When looking for the part online to get an idea of repair cost, there was a bulletin about this being a known issue in the 2021 tahoes with the diesel engines and bulletin states GM extended special coverage for 15yrs/150k miles. When I called dealer to schedule service, I was told this bulletin doesnt come up under my vin number despite it having the same issues, error codes, year, make, model, and engine.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Vehicle lost all braking capability while in motion. Vehicle rolled to a stop with no brakes with warnings for brake system failure, no front collision active. Upon restarting the vehicle the warnings didnt not go way for 1hr. 2 hours later the warnings cleared from the information system but codes remains. Vehicle was taken to Uptown Chevrolet, Slinger WI and was informed of a bad battery as the "cause" of the issue. A bad battery should not result in the loss of braking capability on any vehicle!

ENGINE, FUEL/PROPULSION SYSTEM
1ST ISSUE: 9/2025, after driving from another city to my home at 55-75 mph. As I pulled up home, the car just stalled and wouldn't start. I googled issue to find out it was a commonly known issue by GM. If fuel pump control module had happened while driving faster and not on my street to roll up to curb. I would have or could have been deadly. I find out what part # and local dealer knew there was a recall but told me he never heard about it and charged me for part. I installed in front of home on street and have been trying to get money back after reporting to GM I repaired my fuel pump control module and have been trying to get my money back from a repair done on 9/29/2025 by me. GM says it's looking into still after I keep calling them on status of this notice. I still have old part. I have filled out all reimbursement forms.1st the danger of it failing and now no money. By the time engine light comes on you have no power for any stopping or steering. #2 engine 2021 Tahoe High Country 6.2 L V8: NO RECALL HAS BEEN SENT. GM has known about an engine that has multiple failure issues that could GET YOU IN A SERIOUS ACCIDENT/death BY JUST STOP RUNNING, while just driving at any moment, INTERNAL FAILURES and main seal leaks, MORE! Mine just poured oil out on driveway after driving 6 miles to church and back. this will be the largest and most deadly auto issue in history. They even had dealers now with any on lot with this engine a stop sale order. aprox. 800,000 of these engines are out there, Local GM dealer says THERE IS NO RECALL. 2021 TO 2026 and they have only changed out aprox. 2800 engines and telling me mine sitting in driveway is not on recall. BS. these engines are in their high-end trucks, SUV's, Escalades. Someone needs to get Gm to do what's right and replace with new engines. That have been tested, all issues before someone has to die. Trying to keep silent on internet is sad. Yes its going to cost billions. But to keep customers safe and not scared.

ENGINE
The vehicle stalled while driving down the road and started making a loud ticking noise, the engine light went on. It was brough to the dealership where they did an engine rebuild. They replaced 16 lifters and camshaft, a pulley belt and gaskets. The vehicle was picked up, however, a month later the oil low add oil light came on and the oil tank was more than 2.5 quarts low indicating extreme burning of oil. The vehicle is shuttering on acceleration of low RPMs. Brought it back to the dealership and awaiting further instruction. It caused a major safety concern because it has the potential to stall due to a motor defect on a major highway, putting my family and possibly others at risk of harm or death.
