My 2023 Chevrolet Silverado 1500 equipped with the 6.2L V8 engine experienced a sudden loss of propulsion while driving. The engine did not completely shut off, but pressing the accelerator produced no power or acceleration. I was on the highway going about 80mph with traffic when it happened and left me stranded on the side of the very busy highway. The vehicle was taken to a Chevrolet dealership on September 18, 2026. Following an engine teardown, the dealership informed me that an engine bearing had failed. As of November 5, 2026, the vehicle remains at the dealership while GM determines whether to rebuild or replace the engine. The engine recall had reportedly been completed before I purchased the vehicle. I am concerned about the safety of this failure and whether the recall remedy adequately addresses the underlying defect.

**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 defects. I understand that my truck's VIN is not included in the recall population. I have already contacted the legal team handling the related claims and was informed that my vehicle does not qualify. Nevertheless, I believe my truck's engine failure deserves the same serious attention and consideration, even if the underlying mechanical defect is different from the defect covered by those recalls. What is most disappointing is how General Motors and its representatives have handled my situation. I have been a loyal GM customer for years. I traded in two GM vehicles that I previously leased when I purchased this Silverado. I trusted GM and believed the company would stand behind its products. Instead, I have spent approximately nine months trying to g INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 the federal safety agency's investigation into L87 engine failures following recall repairs, I am requesting further investigation into the adequacy of GM's recall remedy.

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.

On our way to [XXX], we heard a clacking noise coming from our engine. Pulled off the highway and had it towed to Reeder Chevrolet. It was Sunday XXX. On XXX we went to the dealer and they said we spun a connecting rod bearing and needed a new engine. Truck is a 2023 Slverado, 5,3 engine, with about 65000 miles on it. 5000 miles out of warranty. It took 18 days, and cost $12,214.37 to replace. Dealer stated that if I wanted to pursue a warranty claim, we would have tpo pay for them to disassemble the engine, diagnose the problem, then reassemble the engine, and they would send it to GM. GM would decide if it would be covered under warranty. If not, we would be out the cost of the diagnosis. I have always used 0W-20 full synthetic oil when an oil change was required. After searching this problem online, I found a tech service bulletin changing the requirement to 0W-40. We were never notified of the change, and the 2026 owners still say to use 0W-20. Attached are the invoice and recommendation to replace engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine in my 2023 Silverado ZR2 (6.2L L87 V8) failed. It is available for inspection at Rick Hendrick Chevrolet ([XXX]). On XXX at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the Rick Hendrick Chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (N252494003). The L87 recall inspection and oil change was completed on XXX also by Rick Hendrick Chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 RPM started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failed and was replaced at 38k. Transmission shudders, have been back to dealership multiple times for transmission shudder, have been told it was tires, torque converter, and valve body. When those items didn’t fix the issue, I was told it was the engine dfm and that it was normal and not a problem, AFTER they had already acknowledged the transmission issue by trying to fix it with a torque converter and valve body. Engine failed again at 54,604 miles while at high way speeds in rush hour like traffic in between [XXX] and [XXX], while pulling a camper. Truck oiled down the interstate and produced a blueish/milky looking cloud that caused drivers behind me to lock up their brakes because of bad vision, creating a hazard. I was told by gm that they wouldn’t tow the camper that I had to take care of that but they wouldn’t tow send a truck for my truck. Tow truck gets there and says my truck is too big and leaves. I called my own rollback to get my truck 3 1/2 hours later and they came and got it. Was stranded on the side of the interstate for 4 1/2 hours in 90 degree weather, to my knowledge the 2nd truck gm was supposed to send never showed up. Requested a buyback and was denied with no reason given. I have a lot of records if anyone wants them.

Catastrophic Engine failure - Chevy, Silverado 1500, Yr: 2023; Odometer: 33,183: On 8/16/2026 we were traveling down a busy highway towing our camper and the engine completely stopped, no propulsion, no warning lights, no check engine lights; complete failure; we had to coast to side of road. The only thing that indicated a problem is that we started hearing what sounded like marbles rattling, it wasn't loud but noticeable. We pulled over at gas station to check oil, even though we just had the oil changed for maintenance on 7/17/2026 (Odometer: 32,587). Everything checked out ok; however, the marble sound became louder; then within 5 minutes of leaving the gas station, we lost all engine propulsion; the engine completely shut down. Our safety was put at risk as we had no truck engine and were towing a camper on a busy highway; and had to try and coast to a safe location on side of road; miles away from home. We had to call a tow truck to come get us and unfortunately, they could not help us with our camper so then had to call our son to come with his truck to get our camper and us home safely. The tow company also had a difficult time getting the truck into neutral to tow. The truck was towed to our hometown Chevy Dealer. The dealer said that they were not going to diagnose the problem and instead are ordering a new 6.2 engine; same as the 6.2 that failed. We asked if this would fix the problem and they said there were no guarantees as it is the same engine with the same problem. Prior to this event, we received a recall in Sep 2025 and an engine inspection and oil change was performed on 9/12/2025 (Odometer: 25,751); we were told that our engine was ok. As of 9/3/2026; we have been without our vehicle for 17 days.
