I was driving when I received messages saying service esc, forward collision system unavailable, & service traction control. The vehicle began to shake hard when I applied brakes, had loss of power when pressing the gas pedal, and sounded like metal grinding. All of this put my children & I at risk as we were on interstate 35 with cars flying past us and I’m losing power. Initially the spark plugs and coil was were changed to no repair. It was towed to a dealership where they confirmed the lifter & cam failed which put metal in the oil. My only option is a full engine replacement costing 20k on a vehicle that’s 4yrs old. It’s not ok that I have to spend that in order to get my 70k car drivable. Im now without a car, still paying a car note, unable to get my kids places, and having to get help from friends all bc gm can’t build a quality vehicle. I also haven’t been able to get a loaner car. This isn’t happening in only the 6. 3l. This is a widely known issue with the 5. 3l as well. *there were zero warning signs that something was wrong. Drive just fine that morning*.

The vehicle is stuttering, intermittent, jumping, miss firing during acceleration, and hard down shifting. The check engine and forward collision unavailable light flashed as the vehicle struggled to accelerate. According to Chevrolet the camshaft and two lifter has failed.

My onstar system is not working properly. I first noticed the forward collision light then the wifi hotspot features not working. Reached out to onstar they couldn’t help then referred to dealership. Visited dealership 8/12/2025 was told there’s no error code although they see what’s happening. Doing further investigation of my own I found out this is a very well known issue amongst general motors, onstar and the dealerships selling these vehicles. There are varying issues customers are having from wifi not working to vehicles completely shutting down in traffic. Once my visit to the dealership commenced I was informed the telematic control module” is on back order with no estimate on deliveries as there’s “others waiting also” this is a scary situation. I am worried that my issue is going to progress into a bigger problem. I drive 23 miles to work and 23 back. I am scared that my module will eventually fail when I am on the highway…. . This is terrifying! over 80k to play roulette.

A. The emergency brake system, the anti-collision sensor, the vibrating driver's seat alert, the dashboard collision alert lightening. . . . . . All of these gave no alert prior to the collision. B. The failure of the safety devices prevented from me from avoiding a collision that was cause by the other driver (police report available for your peruse) c. They inspected and denied any liability for any failure of their safety devices (and my question to them is if any these are functioning properly as said, then there wouldn't be any collision ) d. Yes, inspected e. There were no waring lamps, no seat vibration, the emergency brake never ceased the car from colliding.

When turning the car left, the power to the engine dies. This also happens on many instances that the power has died to the engine mid drive on the road and hwy.

There were no accidents or near accidents but the computer system was spitting out different problems and telling me that different system were needing service such as the esc system, the steering wheel column l, collision traction , etc plus the engine light came on. Thus occurred on the 20th of June. I took it in for service and they said they fixed the problem but then while coming home on the 22nd the system started acting up again. Took it back to the dealership and they said the computer lost communication. They had to keep my vehicle because they cannot figure out jow to adjust the computer harness and why I am continuing to get the error codes. This vehicle is only 4 months old (3/11/23). I am concerned that could be a major problem if it cannot be fixed.

The vehicle will display “service trailer braking system,” as well as “service front camera,” “service driver assist system. ” these messages along with audible alerts will sound while driving. At random intervals, the forward collision system will also activate with no objects in sight. This causes the driver to become distracted or react quickly in unnecessary manner. This can increase risk of collision when the driver becomes distracted. The vehicle has been taken to Chevrolet multiple times and we have been told a faulty wiring harness is the cause. We own two of these vehicles, same make, model and year. This has happened in both vehicles.

We were traveling approximately 30 mph approaching an intersection of a 5 lane road. A vehicle in front t of us had pulled into the turn lane. As we approached the vehicle that was already completely in the other lane, our car suddenly braked to a complete stop even though my foot was only on the accelerator as it is a 40 mph speed zone.

I was driving on the freeway about 65 mph on Saturday June 18. In a sudden instant, there was a message on my dash "brake module failure" and "speed limited to 62 mph". Also warning message that "forward collision warning was off" , etc. The abs light, the "check brakes light", and the check engine light all were on. Also, the power brakes went completely out and to stop I had to press really hard with manual brakes. I don't think a small framed person would have been able to stop and if I had been at a moment where I needed to stop quickly I don't think I would have been able to stop had there been a need to stop quickly. The dealer tells me that the brake master cylinder failed. The car has 43,000 miles and has been well maintained.

While driving, I received a notice identifying a problem with the esc system and that there was a brake system failure. I have received an advanced diagnostics alert about the antilock braking system. The vehicle was difficult to stop and required excessive pressure on the brake pedal.

Car suddenly swerved, loud knocking started. Multiple system failures started flashing. Forward collision, ecs, traction control, the car was vibrating, jerky. I have multiple videos as well. The dealership literally told me they’d seen a ton of these when I called immediately and then told me to keep driving because the damage was done and if the engine died well then it’s under warranty. I have 3 children under 5 and that is not an appropriate answer when I asked about it being safe to drive considering it’s jerky/shaking/knocking, and has multiple systems down. I’ve also googled and joined forums and this is apparently a common issue in the 2021 v8s and chevy refuses to issue a recall. Would be more than happy to provide videos as well it won’t let me upload them with the photos. Was told it could be weeks before they even have parts.

In traffic, approx. 10-15 mph car in front stopped short. I put foot on the brake pedal and pushed the brakes pedal to the floor. The car did apply the brakes equally as hard as I was appling brakes at the pedal.

We were stopped at a red light on florida state road 54 turn lane to go on us 75 when the other car rear ended us and drove us into the car in front of us. No air bags deployed. Florida highway patrol crash number 88482185. We only had the vehicle for 10 days.

The a/c condenser experienced a premature failure, loosing all the freon. This is a known issue and chevy has a special program to address the issue for a select number of vehicles. However, my vehicle is not covered under this recall even though I have the same problem as the ones covered under the recall. This is an environmental concern as well as a safety issue as it can cause window fog. Chevy needs to step up and pay to fix the issue for all the affected vehicle's. In addition, the front collision warning system is a joke, its inconsistent and rarely works.
