2024 Chevrolet Suburban Engine Problems

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 took my 2024 Chevrolet Suburban to get repairs associated with GM safety recall N252494000 - L87 Engine Loss of Propulsion. My vehicle "passed" the test, so the "correction" employed by GM is that "vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filer replacement, and an owner's manual insert." All of this was done free of charge. However, the owner's manual insert states that "For future engine oil changes, use SAE OW 40" oil. This updated owner's manual insert, which is provided as a solution to GM's recall of a faulty connecting road and/or crankshaft, causes the future costs of oil changes to increase from $160.00 to $230.00. Assuming quarterly oil changes, this will increase the cost of operating this vehicle to increase by $2,800 over an estimated 10 year lifespan. This increase should be covered by GM. GM sent me a letter that states, "If your dealer fails or is unable to remedy this defect without charge, or within a reasonable amount of time, you may submit a written complaint to the Administrator, NHTSA." By passing on the cost of the increase in oil change for all future oil changes, GM failed to remedy this defect without charge. I submit this claim because GM filed to remedy this defect without charge. Please see highlighted portions of attached documents in support.

I parked at my home, approximately 5 minutes after arriving home my grandson ran in yelling papa your car is on fire. The engine was on fire, shooting flames onto the windsheild. The cause of fire is unknown at this time.

We were driving down the [XXX] in Wichita KS when our 2024 Suburbans engine shut off and the car went into neutral. The display said “ "conditions not correct for shift". We were able to safely coast to the nearest exit [XXX] and we completely stopped at the bottom of the exit ramp. We contacted onstar who dispatched Kansas Highway Patrol who blocked off the exit until we could get the vehicle towed. The car is currently at the dealership, being that it is Sunday they are closed so more information tomorrow on the issue. The photos are of the car being towed from The incident location and dropped off at the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

6.2L engine failure at 9600 miles

The dealer stated the 6.2L engine had a bearing failure. When driving on 12-24-24 to a family event the dash lights all lit up and the car shut off. I was barely able to put the Suburban into neutral to pull off to the side of the road. Once stopped, the Suburban wouldn't start or even go into neutral so I could push it further off the side. This is extremely dangerous. My entire family was in the car on a very busy day (Xmas eve) without the ability to move the car in any way. Even when the tow truck driver arrived, he stated there isn't a way to force it into neutral. I also first learned about the 6.2L bearing issue from him. His 2023 Suburban was in the shop for the exact same issue. My 2024 Suburban has less than 13,000 miles on it before the failure!

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.

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.
