2025 Chevrolet Tahoe: check engine light

Filed Oct 26, 2026 · Engine · TX

While driving on the highway, the engine started making a knocking noise and the vehicle shut down causing us to have to pull over on the side of the road in the middle of highway traffic. The engine light came on and the vehicle would no longer drive leaving my family stranded on the side of the highway. The vehicle had to be towed 200 miles back home.

- Repeated check engine lights on for "traction control", "service ABS", and "ESC". - Repaired several components of wheel hub assembly, speed sensor, and breaking module. - Wheel speed sensor repaired 3x - Now dashboard messages are reading "service brake assist", "service steering column", and "service transmission now unable to shift soon". - Athens Chevy never called for a GM engineer and wont return phone calls. We have twin newborns and the vehicle is currently parked in a driveway because we are not confident in its ability to operate safely. I have stressed this to every GM service tech I've spoken to and the lack of concern is concerning in itself.

This 2025 Chevrolet Tahoe has experienced three separate and recurring engine-related failures. The first failure occurred at approximately 41,350 miles and required replacement or repair of the lifters and camshaft. The vehicle remained at the dealership for approximately 15 days. The second failure occurred at approximately 54,619 miles and involved another lifter failure along with traction control problems. The third failure occurred at approximately 65,140 miles. The Check Engine warning light illuminated while the vehicle was being driven, and the vehicle again experienced engine-related problems. The vehicle has now been at the dealership for more than one week, and no repair or permanent solution has been provided. I am concerned that these repeated engine failures and traction control problems create a serious safety risk, particularly because the vehicle is driven on public roads and highways. Despite previous repairs, the engine problems continue to recur. I am requesting that the federal safety agency investigate these repeated safety-related failures.

I am filing a safety complaint regarding my 2025 Chevrolet Tahoe Premier for repeated brake assist/braking failures. Most recent incident: While driving, the check engine light came on. I turned the vehicle off for approximately 10 minutes and restarted it, but the check engine light remained on. Approximately 20 minutes later, multiple warnings appeared on the dash including: “Brake Assist Failure Press Hard to Brake,” “Speed Limited,” and “Service ESC.” At that point, braking ability was severely reduced. I was close to my destination and approached a stop sign. I intended to roll through the stop sign because the brakes were not functioning normally, but another vehicle suddenly approached. I pressed the brake pedal with both feet. The brakes were stiff and hard to press. The vehicle still did not stop properly and came to a stop in the middle of the road past the stop sign. After arriving at my destination, the vehicle sat for approximately 1–2 hours. When restarted, the brakes appeared normal again, but the check engine light remained on. In the MyChevrolet diagnostics app, it then showed warnings for Engine and Transmission System, Transmission System, and Four Wheel Drive System. While driving to the dealership afterward, the vehicle also began shaking. This same issue previously occurred on April 16, 2026. I was driving on the interstate when the brakes lost assist and the dash displayed “Service ESC,” “Brake Assist Failure Press Hard to Brake,” and “Speed Limited.” After reaching my destination, I was told by someone at the dealership to turn the vehicle off for 10 minutes to see if that would fix things, so I turned the vehicle off for about 10 minutes. When restarted, all warning lights were gone and braking returned to normal. I still drove the vehicle to the dealership that same day for service. This is a repeated, intermittent brake failure / brake assist failure creating a serious safety hazard and near collision risk.

While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes P0353 and P0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine

I was driving up to a border check point and slowed down at the guard shack. Once cleared I released the brake and tried to accelerate. The vehicle shut down completely. I tried to restart it and the check transmission warning came on. The vehicle would not restart. I was blocking the lane at the border check. After a few minutes I was able to start the vehicle and limp over to the shoulder of the freeway. There was no power and loud knocking and squealing from the engine compartment. Engine light came on and several other warning lights that I don't recall. I was in the desert with 3 dogs in an unsafe area for 7 hours until I could get help. Vehicle was towed to the dealership and is currently under diagnosis but so far code P0016 and metal pieces in the oil.

Bought the 2025 Chevy Tahoe, had about 680 miles on it. 400 of which were from the dealership. Had the pleasure of driving it for a week. Check engine light came on and was told that the transmission valve body had gone bad. The issue regarding that particular transmission has existed since 2019. However the part needed is allegedly on back order, and GM has no idea when they will get that part in.
