2023 Chevrolet Silverado engine problems

“As I was exiting the exit ramp, you could here a noise from the suspension. Then a bunch of smoke came out and there truck seized up and stopped. I got out there was fluid/oil leaking everywhere. There was a trail of fluid following the car down the exit ramp. The truck was telling me to restart but I didn't not due to safety concerns. We had the car towed to the local Chevy dealership where it is being diagnose. There were no warning lights prior or any notification that there was an issue.”

“**XXX** **FROM:** [XXX] **TO:** General Motors Company, Chevrolet Customer Assistance, GM Financial, and Wallace Chevrolet **RE: FORMAL COMPLAINT AND FINAL REQUEST FOR RESOLUTION — 2023 CHEVROLET SILVERADO 1500 RST ENGINE FAILURE** **Vehicle:** 2023 Chevrolet Silverado 1500 RST **VIN:** [Insert VIN] **GM Financial Account:** [Insert Account Number] To Whom It May Concern: I am writing this letter as my formal complaint and final request for assistance regarding the engine failure of my 2023 Chevrolet Silverado 1500 RST. Since XXX, when my truck's engine failed, I have made repeated attempts to resolve this situation with General Motors and Wallace Chevrolet in [XXX]. I have contacted GM, visited the dealership multiple times, and personally spoken with the mechanic who examined my truck. The mechanic informed me that an engine lifter had seized or frozen, resulting in a serious engine failure. I have always properly maintained this vehicle. I have records of oil changes, routine maintenance, and other services. This truck has not been neglected or abused. I am aware of GM's extensive recalls involving hundreds of thousands of vehicles with serious engine…”

“My 2023 Chevrolet Silverado 1500 ZR2 equipped with the 6.2L L87 V8 has exhibited abnormal engine behavior since shortly after purchase, well before GM announced the engine recall. Symptoms include extremely loud intermittent metallic lifter/valvetrain noise during cold starts, persistent rough idle, and noticeable engine vibration that causes the truck to rock back and forth after warming up. Paradise Chevrolet and Bunnin Chevrolet subsequently performed GM's prescribed PicoScope inspections, and both reported passing results. The oil-viscosity recall remedy was also completed, but the symptoms remain unresolved at 47,133 miles. I am concerned about potential internal engine damage and the possibility of sudden engine failure or loss of propulsion. Given NHTSA's investigation into L87 engine failures following recall repairs, I am requesting further investigation into the adequacy of GM's recall remedy.”

“I have received a voluntary recall notice on my 2023 Chevrolet Silverado. The recall states that the vehicle may have a condition which can cause the Fuel Pump power control module to fail. If this happens fuel flow to the engine could be interrupted causing the motor to shut off. Would this be considered a safety concern if the engine shuts down on th highway?”

“Engine failure on our 4-cylinder- it just quits same problem as on the 6-cylinder - it just stops running or runs rough. No warning signs and no indication that it is about to fail. Hazardous on the freeway. Vehicle has been at the mechanics for a month now and GM keeps saying the engine is on backorder.”

“I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident…”
