2024 Chevrolet Suburban: engine failure

Filed Oct 14, 2026 · Engine · AZ

Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start. People stopped to help us and tried to jump vehicle without success. Suburban was towed to a Chevy dealership and we were told the Suburban's engine seized. In researching this issue, we came across the federal safety agency's investigation case EA26005. Our VIN does not fall in to this recall.

While driving down a two-lane blacktop road at 70 MPH (the posted speed limit) the engine, a 6.2 L L87 with a little over 15,000 miles, grenaded and seized. At the time I recall a warning message that said something like "engine shutdown". Fortunately the electronic transmission self-shifted into neutral so the car could coast to a stop. Had it not done this a loss of control would have been likely at this speed. The vehicle was towed to the local Chevrolet dealer in Bozeman, Montana (Resseler Chevrolet) where it was confirmed the next day the engine had seized. The dealer is currently replacing the seized engine with a replacement long block. The dealership currently has the engine and is planning to ship it back to Chevrolet or GM for tear down and inspection. They are also replacing the radiator and all coolant hoses as a precaution. Two weeks prior I took the vehicle to the same Chevrolet dealer complaining that on one day the engine shut off four times within 1 mile. Each time it displayed a warning message that said "restart engine", which it did each time. I also complained about a ticking noise that began in the engine at 12,000 mile. The dealer reported that the engine sounded fine and that they could not reproduce the engine shutting off on its own. This engine was NOT part of the large L87 recall. At time of purchase I was told by the selling dealer (Kendall Chevrolet in Maryville, Washington) and the local dealer (Resseler) that the engine was assembled after assembly line procedure were put in place to avoid the same issues as the recall engine. I've been and engineer for 46 years. The problem with this engine is not the assembly line, it is the never before used tight moving component tolerances and the water thin oil demanded by the manufacturer. The design shortcomings are compounded by systems such as cylinder deactivation and auto stop that significantly acceleration engine component wear.

On May 2, 2026, while the vehicle was in operation, the engine suddenly shut off without warning. At the time of failure, the instrument panel remained illuminated; however, the vehicle would not restart. In an effort to resolve the issue, the battery was replaced, but this did not correct the problem. The vehicle was then towed to a local Chevrolet dealership for further inspection and diagnosis. Following their assessment, I was informed by the dealership’s service department that the engine had seized and that metal debris was present in the engine oil, indicating significant internal engine failure. I was further advised that a replacement engine has been ordered. At no point prior to this incident were there any warning indicators, abnormal noises, or performance issues that would have suggested an impending engine failure. The sudden nature of this incident raises concerns regarding the cause of failure and whether it may be related to a defect or internal mechanical issue.

Complete and sudden failure of the L87 V8 engine at 70 mph on the highway. Had to maneuver to the right shoulder and coast to a stop. Engine was seized and would not restart. Waited 4 hours on a dangerous highway for a tow truck which took the Chevy Suburban 200 miles to my home Chevrolet dealership. They have ordered a new engine but it is on backorder so no ETA. Vehicle was built 06-26-2024 and has not been recalled so Chevy says I do not get the extended warranty on the replacement engine.

Sudden power loss on highway. Engine would not respond. We were fortunate to have been able to pull over to the side of the road but in an unsafe merging area. Vehicle restarted after multiple attempts, but engine would not exceed 3000 rpm causing unsafe speed on highway. Engine died again causing total power loss. I was able to coast down the hill to safely park out of the way of traffic. Tow truck was needed. Vehicle was towed to dealer where it was purchased. After inspection, the engine was confirmed to have failed. The dealer advised for engine replacement as part of the L87 recall. This engine was previously inspected less than 10,000 miles prior as part of the same recall, and the higher-weight oil had been used since per the manufacturer's recommendation. However the inspected engine appears to have failed regardless. This sudden loss of power happened about two weeks prior, with the driver able to pull to safety and restart. It was dismissed as a fluke since it did not occur for the next two weeks.

I was entering the interstate, at 65 miles per hour, and went to set the cruise once I reached 70mph, and noticed that I was losing power, the engine had stopped and we dangerously lost speed on a interstate where folks were traveling north of 75-80 mph. I costed to the shoulder and tried to reset with no luck. We called Onstar and had it towed to Hendrick or Monroe NC. We found out that this was an engine failure and the long block had to be replaced. This left us stranded without a car to drive to our cruise —GM told me I could buy plane tickets and they’ve never denied reimbursement. Unfortunately they denied it once I submitted all the receipts. It been a horrible experience with no help from GM.

6.2L engine failure at 9600 miles

While driving in the left lane of a two lane highway at highway speed of approx 65-70 mph the engine shut down. The instrument cluster said to “Press button to start engine”. I had no power. There was no throttle response. Luckily I was on a slight decline and was able to safely change lanes by coasting into the right lane then the shoulder. I was able to put the vehicle into park. The vehicle did restart. I took the vehicle to a Chevrolet dealer and was immediately told that there was an internal engine failure. I could have been rear ended or worse. This is a very serious issue. Upon doing some research, I found that the same thing has happened to many other people. This is very dangerous. Apparently this is becoming a major issue for the GM 6.2l eco tec engine. I hope that the next person this happens to doesn’t freak out and have an accident. If this happens to the wrong person, someone is going to lose their life.
