Engine Seized. Truck wouldn’t shift to neutral to be towed. Tow Truck with Dollies had to be called. Blocked/Detoured traffic for six hours at the main entrance to CMH AirPort Construction Parking. Yelled at by Security on site to move truck. Absolutely Humiliating.

I bought the truck at 6,400 miles. I was on my way to the dealership because of a clanking sound I heard the day I brought it home. It was at 7,007 miles when it went down. I had it for a total of 5 days. I was coming from a stop when it suddenly lurched and I heard rattling and clanging noises. It had been making noises around 6500 miles that were most likely drivetrain related. Luckily, I was on a side road when the engine locked up. No warning lights. Had the truck towed to the dealership. They said the engine needs to be replaced. Still no delivery date given.

Engine blown at 3,000 miles while going 73 MPH

The 2026 Chevy 1500 Silverado 6.2L engine had a slight knocking sound from the date I purchased it brand new in march 2026. I was driving home on a evening in July 2026 and the truck began to squeak, knock very loudly and shake violently. The truck then locked up and completely shut off while I was driving 45 mph down the highway. The vehicle had approximately 3,000 miles on it when the incident occurred. The truck’s violent shaking and sudden loss of power while traveling 45 mph created an immediate risk in which I did not have control of the vehicle and could have caused me to be unable to safely maneuver out of traffic. Thank God there was light traffic at the time and also a wide empty parking lot straight ahead of me when the truck shut down. The incident also placed other drivers in danger of colliding with my disabled vehicle or taking sudden evasive action that could cause an accident. I had it towed directly to the dealership service department and according to their report, "found catastrophic internal engine failure."

Driving on the interstate and the truck had a horrible vibration. It smoothed out and it did it again. I got off at the next exit and the engine was making a horrible knocking noise. I had it towed to my Chevy dealer for inspection. They drained the oil and found excessive metal in the oil. They decided that the engine needs to be replaced. The truck only has 4524 miles on it and it was purchased in June of 2026.

Engine seized and stalled while vehicle was in motion. This resulted in failure of power steering assist and power braking assist. This made vehicle extremely difficult to maneuver safely out of the flow of traffic. The engine seizure was confirmed by a Chevrolet dealership. And the engine was replaced by the Chevrolet dealership. There were no warning lamps. The engine made some unusual noises moments before failure.

My 2026 Chevrolet Silverado experienced catastrophic engine failure at approximately 12,000 miles. The vehicle was out of service from June 19, 2026 through August 27, 2026 while the engine was replaced. This is our family vehicle and is regularly used to transport my two young children. I remain concerned about the safety and adequacy of the remedy following such an early catastrophic engine failure. I requested that GM repurchase the vehicle or provide trade assistance so that I could move my family into another vehicle; both requests were denied. I am submitting this complaint so the federal safety agency has a record of the failure and my concerns regarding the remedy provided.

I am submitting this formal statement regarding a severe, recurring safety hazard involving sudden engine stalling and internal mechanical noise on my 2026 Chevrolet Silverado 1500.The vehicle has experienced multiple sudden engine stalls during low-speed deceleration, specifically while letting off the accelerator pedal to execute low-speed turns into parking lots. When the stall occurs, the engine dies completely, causing an immediate and dangerous loss of power steering and power braking assistance mid-turn. Because the vehicle shuts off completely while still in motion, I am forced to bring the truck to a dead stop, shift the transmission out of Drive and into Park, and completely cycle the ignition system to restart the engine.There is a distinct, audible mechanical ticking sound coming from the engine compartment during operation. Crucially, the vehicle has never illuminated a Check Engine Light, displayed a dashboard warning message, or given any advance electronic indication prior to or during these sudden stalling events.This vehicle's build window falls directly into the scope of the federal safety agency’s (the federal safety agency) active Engineering Analysis (EA26005) investigating catastrophic valvetrain and engine failures on GM 6.2L L87 engines. Because this defect causes an unexpected loss of vehicle control with zero diagnostic warnings, it poses an immediate highway safety risk to myself and others.I request a full diagnostic scan for hidden or pending fault codes, a physical inspection of the valvetrain/Dynamic Fuel Management (DFM) system, and an inspection of the engine oil filter for metallic debris indicative of internal bearing degradation.

I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] area. It was around 8:30 in the morning and we had been on the road since the 6 o'clock hour. We were towing our our 20' fishing boat at the time. We were in the left most lane, passing a semi tractor trailer. I signaled and moved back in the 3rd lane after the pass. We were now the vehicle in front of the semi. At this moment, the engine locked up. The torque converter which had been locked at highway speed came unlocked. The transmission started aggressively downshifting looking for torque, RPMs racing upwards of 6k. We were now on an uphill, towing, with a seized engine in front of a semi. In the next lane right was a family in a newer lincoln navigator going freeway speeds. Aside from the transmission, the engine was silent, the accelerator did nothing. A message pops on the screen. "Shift into Neutral" is says... a fraction of a second later "Restart Engine" or alike. The start button was unresponsive. We're losing speed, the sem i is right on the back of the boat now, the [XXX] navigator was even in the lane with the semi. This is where split second decision making mattered. I glanced to the right most lane, empty. All I could do to get off the interstate was to yank the wheel to the right and at what felt like a 45 degree angle, rip across the three lanes to the only shoulder available. The navigator was obviously caught off guard, as they had been slowly gaining on/passing the semi at the time. The navigator locked up it's brakes, skidding out of control before regaining it. Now it's still. Engine off. Only the noise of the freeway and the navigator driver, still honking profusely and deservedly. My heart was just pounding. Breathe. You're all alive. Thank God.
