2023 CHEVROLET SILVERADO 1500 Complaints

While traveling on the interstate towing a fifth-wheel camper going 55 mph, a message appeared on the dash instructing me to press the Start button. I pressed the Start button, but the vehicle would not start. When I pressed the Start button the entire instrument cluster and navigation display went out. We were able to safely coast to the breakdown lane, skidding to a stop. We remained in the breakdown lane on a busy highway on a holiday weekend in 90+ degree heat for 7+ hours before being towed to a nearby dealership. When the right type of tow truck arrived (capable of towing the truck and camper off the highway), the driver had to remove the driveshaft before the vehicle could be towed to the nearby dealership. This is because of the electronic shift. If the vehicle is not running it cannot be shifted out of park without a special tool. We felt very unsafe sitting in the breakdown lane with cars whizzing by shaking our camper and vehicle at each vehicle passing. Not 1 time did the police stop to provide assistance/make sure all were ok, etc. The vehicle has since been towed to the local dealership and after they inspected the vehicle it was determined the engine seized due to debris in the engine. A replacement engine is on backorder. The engine had already been inspected for the recall and GM 6.2L L87 "fix" was performed, but this did not stop the engine from seizing.

The entire engine was replaced at 5 miles due to catastrophic failure. Work was performed by Ciocca Chevrolet in Atlantic City New Jersey

Check Engine has been triggered by faulty TCM. Vehicle is a 2023. Dealership says they have repaired a few others.

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6.2L V8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0W-40 oil installed prior to the failure.

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. while accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into Neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated P0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them

Transmission went out while driving on highway, entering limp mode. Ended up needing a valve body replacement at only 20k miles which was covered, but now I am having more transmission issues still with delayed forward engagement and slipping gears and it is only at 65k miles. Seems to be a lot of customers having the same issue. Took months for the truck to be fixed as "many other trucks" were waiting on the same part according to dealership.

While driving, the vehicle suddenly displayed “Service ESC” and “Service Traction Control” warnings. Shortly after, the engine stalled and the vehicle became difficult to restart. Vehicle experienced rough running/misfires and loss of power. Diagnostic trouble codes retrieved included P0300, P0106, P3498, P00FF, and U1962. The issue appears intermittent but creates a serious safety concern due to unexpected stalling while driving. Concerned about possible electrical, engine management, or stability control system failure affecting safe operation of the vehicle. No prior warning before incident.

What component or system failed or malfunctioned, and is it available for inspection upon request? Engine seized and vehicle was towed to dealership. It is available for inspection. How was your safety or the safety of others put at risk? Loss of propulstion, described below. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, dealership where originally purchased. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected at dealership by GM/Chevrolet technician. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None prior to failure Detailed description: On 5/21/2026, during normal driving, the engine in my truck lost propulsion due to a major internal failure. This is a 2023 General Motors 6.2L (L87) engine that was inspected at the dealership where it was originally purchased for the previously issued NHTSA "loss of propulsion" recall and passed without any noted issues. This engine only has ~20,000 miles on it. The engine failed in relatively heavy traffic and could have easily resulted in a serious accident due to inability to route my vehicle to a safe area while under power. This all happened without any prior warning, no check engine lights, noises or lamps or symptoms. The dash simply illuminated with a "Press Start" message.The truck was towed to the dealer for evaluation. The dealer called me today (5/26/2026) stating the engine was seized and a new engine would have to be ordered from GM for installation. This event occurred while the vehicle (2023 Silverado ZR2) is still under the original 36 month/36,000 mile warranty.

The contact owns a 2023 Chevrolet Silverado LD Crew. The vehicle was taken for a recall repair due to a the crank shaft bearings failure. The contact stated that awhile after the repair was completed , the engine was ticking. The vehicle was taken to the dealer again, where it was diagnosed with metal shavings in the engine. The dealer stated a new motor may be needed which would be the fourth motor installed. The vehicle was not repaired. The manufacturer was notified of the issue. The approximate failure mileage was 40,000.
