Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning and wouldn’t even start again. Warning light for low engine oil came on. We were stuck and couldn’t even put the vehicle in neutral to be towed out of the intersection.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) in November 2025 by the local dealer. The contact stated that the engine had passed the inspection, and a higher viscosity oil had been added along with the other steps stated in the recall. The contact stated that while driving approximately 55 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond. The gear shift indicator indicated that the transmission had been shifted into neutral(N). The contact attempted to shift to drive(D) when the vehicle stalled. The vehicle was stopped but was unable to restart the vehicle. The vehicle was towed to the same dealer who had completed the recall repair. The dealer diagnosed the vehicle and determined that the engine, starter, radiator, and fuse block needed to be replaced. The vehicle was being repaired. The manufacturer was informed of the failure and a complaint was filed. The failure mileage was approximately 48,000.

My 2023 Chevrolet Tahoe LS has experienced repeated service issues within the first year of ownership. The vehicle has been in the repair shop five separate times and out of service for approximately five months total. Due to extended repair periods, the mileage remains extremely low. A primary concern involved the steering system. The steering wheel was noticeably off-center while driving straight, requiring continuous correction to maintain proper lane position. Steering-related components were inspected and replaced. There were no warning lights present at the time. However, improper steering alignment raised safety concerns regarding vehicle tracking and stability. The vehicle has been inspected and repaired by authorized service providers. I am submitting this complaint to determine whether this reflects a broader safety-related issue with this model year.

I took my 2023 Chevy Tahoe in for all recall corrections promptly when the notices were received. My last recall was to run a check to see if my motor was one of the defective 6.2L engines. It was determined it was not and the dealer changed my oil to the new required 0w-40w. Now a month later as I am accelerating on to the freeway ,I am at 65 MPH I cross traffic to merge on to a connector bridge and my car RPM's go through the roof and the car starts to slowly lose power. Zero warning lights are on at this point just decreasing power. As I am on the bridge my engine light comes on with a engine oil hot idle engine notice I am now at 35 MPH. Then a oil pressure low turn vehicle off notice comes up and we are at 15 MPH the car turns off. The screen says press start again but as we do it wont do anything. It then randomly starts turning off and on. We got to a point on the bridge where we could coast to the connecting freeway below and pull over. My car was towed to the dealer where it has been confirmed it needs a new motor with no know ETA of the new motor.

Since 15,394 miles vehicle has experience multiple system failures upon vehicle startup. 2/24, 2/25, 12/25, 1/26. In all of these 4 instances the brakes become spongy/hard, steering wheel locks, and I am not able to control vehicle. Dash lights up; "Brake system failure - 43mph top speed", "Fwd collision system unavailable", "Service traction control", "Service ESC", "Service steering column lock", "Service brake pad monitor". Dealership has replaced, Telematic control module, Electronic brake control module (EBCM), Serial data gateway module, Park assist module and most recently they replaced the battery and cleared the codes to "fix" the same intermittent but recurring condition. In 11/24 Recall N242447990 was performed, reprogramming of Brake system control module and Serial Data Gateway Module, the exact same issue happened before and after the recall.

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)

I purchased a 2023 Chevy Tahoe in Oct 2025. Since then, I have been trying to figure out how to set up the myChevrolet app. The OnStar button doesn’t work so I called OnStar. After multiple calls, they told me that the account is linked to the previous owner and can’t be transferred because of a faulty telematics communications module. The faulty module is also causing the clock to run slow, which indicates battery drain is beginning. The OnStar module failure poses a huge safety and privacy risk. Safety concerns include battery failure that can cause me to be stranded and the fact that the previous owner has the ability to start my vehicle at any time, even while parked in my garage posing a risk to my family’s health/life with trapped carbon monoxide building up. Privacy concerns include the previous owners ability to track my vehicle, lock and unlock doors, access my contacts, call log, location, and more. This is a significant risk. The dealership should not have sold me a vehicle with a defective module without repairing it and now refuse to fix it. This should have been included in GMs factory recall for 2023 Tahoe TCU’s or a new recall should be issued. Consumers should not bear the burden to fix a widely known safety, health, and privacy risk.

When I started my car at home, all of the dash warning lights came on, one after another. I put the car in reverse and started backing out of my driveway. I tried to stop but there were NO BRAKES! I slowly pulled back into my driveway and turned the car off. I had to take off work that day because I didn't dare to drive the car. The next day I started the car up and the check engine light was on. Luckily, I had brakes and I could go to work. Now, a day later, my engine light is not on. I made an appointment at the dealership. They can't get me in until mid February so I'm stuck with this problem, not knowing if the brakes are going to fail while driving. Oddly enough, when talking to a co-worker who has a 2023 Chevrolet Suburban, she recently had the same exact problem with her car. She has an appointment scheduled as well. I also read a complaint on this website that had identical problems. This car only has 8500 miles on it. It's still new! Someone is going to be killed or hurt very badly if this ever happens while driving. Please look into this.
