While driving on the interstate in nevada (speed limit of 80mph) I had my 2016 Suburban throw a rod through the engine block as I was in the left lane passing a uhual on an incline. The vehicle made a loud bang, lost all engine power and protruded smoke so thick I could not see cars behind me. I was thankfully able to coast to side of the road without being hit. I then exited vehicle and there was a fire in the engine bay which I put out with a gallon of water in the trunk. My mechanic confirmed the thrown rod and hole in the block and that the car needs a new engine now. I had a cel a few minutes prior to throwing the rod for an engine knock.

Vehicle has been at dealership for a month with no idea on when parts will be available. They say they have no idea on when a valve body part will be available.

My 2021 chevy Suburban premier suffered a sudden internal engine failure due to collapsed lifters and a damaged camshaft. The vehicle began experiencing performance issues, including rough idling and loss of power. After taking it to a certified mechanic, it was confirmed that the lifters failed and caused significant damage to the camshaft, requiring a major repair that I had to pay for out of pocket. This issue is widely known among gm vehicles with the 5. 3l and 6. 2l v8 engines and has been the subject of numerous technical service bulletins and customer complaints. While my vehicle is not included in the current recall (NHTSA 25v-274), which covers crankshaft and rod failures on l87 6. 2l engines, this lifter failure is part of the same engine family and indicative of a broader defect in gm’s v8 engine platforms from 2021–2024. I’m requesting that NHTSA investigate these lifter and camshaft failures as a safety and reliability concern, and urge gm to expand the existing recall to include these known engine issues. Many customers, including myself, are incurring thousands of dollars in repair costs for problems that are clearly tied to manufacturer defects.

There were no warning lights illuminated. The contact stated that the vehicle failed to accelerate above 25 mph. The contact stated that the failure was related to NHTSA campaign number: 25v274000 (engine and engine cooling).

The vehicle was taken to an unknown local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no further assistance was provided. The failure mileage was 132,000.

The lifters in the engine are failing.

Worried about the safety of driving this vehicle due to the numerous reports of the engine seizing while driving. I have read about there being hundreds of thousand vehicles with the same engine having this problem. Thanks.

I’m filing this complaint regarding a serious safety concern with my 2023 Chevrolet Suburban. The vehicle is affected by NHTSA recall 25v274 related to a potential defect in the crankshaft or connecting rods. Gm has confirmed the recall, but there is currently no fix available, and dealerships are not equipped to inspect the engine to determine if it’s defective. This leaves us driving a vehicle with a known risk of sudden engine failure, especially at highway speeds or while towing. In addition, my vehicle is also experiencing a transmission issues and is expected to be in the shop for up to three months for repairs. The combination of an unresolved engine recall and a failing transmission makes this vehicle unsafe and unreliable. We are a family of six with four small children (two in car seats, two in boosters). We purchased this Suburban specifically for safety, towing capacity, and long-distance driving. Right now, we are left without a safe or functional vehicle. Gm refuses to provide a comparable rental and has offered only $44/day, which doesn’t cover anything close to what we need. We’ve attempted to work through gm and our local dealership to resolve the issue, but we’ve been passed back and forth with no solution. I’m concerned that gm is knowingly allowing vehicles with unresolved safety defects to remain on the road with families inside them. I’m asking NHTSA to investigate the handling of this recall and the delays in the transmission repair that are putting families like mine at risk.

Out of the blue, while driving, my car started lurching and making a weird rattling noise. I was able to make it to a mechanic, where I learned the cylinder lifters collapsed and crankshaft were broken. The mechanic told me this is a common defect for gm motors. My vehicle is only five years old, so to learn we have a $10-20,000 repair on our hands was paralyzing and devastating.

I am contacting you regarding a critical engine failure in my 2021 Chevrolet Suburban lt, which is equipped with the l84 5. 3l v8 engine. Due to a valve lifter malfunction, the engine suffered catastrophic failure, with metal shavings found throughout the oil system and internal components. I’ve been quoted approximately $14,000 by the dealership/service center to replace the engine, and the vehicle is currently awaiting repair. I was driving the car with my son when the vehicle began to shake, make ticking noises, and the check engine light went on. I pulled off the road and several error codes popped up including "service esc" and "service traction control. " this is the second time that a lifter valve has failed on this vehicle. In 2022, the lifter valves on the left side were replaced under warranty. It appears one of the left side lifter valves failed again, this time causing significant cam shaft damage and damaging the engine. Given that this issue appears to be affecting many owners with similar engine configurations, I would appreciate your assistance in investigating this matter to see if these issues stem from possible manufacturing defects which could result in engine damage or failure. I reached out to general motors to ask if I qualify for extended coverage or any known service programs to address this situation and they told me I should talk to the dealership because they are unwilling to offer assistance. I've attached receipts for repair of the lifter valve in 2022 and the current diagnosis of engine failure, cam shaft damage, and lifter valve failure. This vehicle is only four years old and was regularly serviced by general motors. It is available for further inspection. Please let me know what other documentation or information you require. Thank you.

While driving cross-country, my 2021 Chevrolet Suburban z71 (5. 3l v8) experienced several progressive symptoms leading to total engine failure. For months prior, there was a noticeable coolant smell from the engine bay despite no visible leaks. Multiple chevy/gm shops noted the smell, and pressure tests showed no external coolant loss. On the trip to colorado, the engine ran normally, but at idle, the temperature would steadily rise to ~235°f before fans would engage. Upon arrival in colorado, I found the coolant reservoir was low again. The final time the vehicle started, it shook violently at idle for nearly a minute before settling. The next day, it would crank but failed to start, and has not started since. There were no check engine lights or warning messages at the time of failure. A gm dealership has since diagnosed the engine as “locked up” and quoted a $14,500 remanufactured engine replacement (gm part 19420610). I’ve been told my engine is the 5. 3l v8 (rpo l84), which is currently not included in gm’s safety recall 25v-274 affecting similar failures in the 6. 2l l87 engines. Right before this occurred, I had a nc inspection (passed), a fresh oil change the same day, and had coolant added. This failure happened without warning, while traveling out of state, leaving the vehicle stranded in a garage and requiring towing. The situation presented a safety risk and significant financial burden. Given the similarities in symptoms and failure type to the recalled l87 engines, I believe this may be a related manufacturing issue.

The 2023 Suburban started shuttering on idle and loosing power on drive due to a misfire in bank 4, the fuel injector was changed, but the problem persisted. And now the dealer says that I need to change all 8 injectors. 2900 job on a car with 54000 miles. Crazy.

Currently own a 2018 chevy Suburban with a lifter issue in the engine. This is a known issue with chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in regal chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and chevy has done nothing to help support loyal customers.

We experienced catastrophic failure while driving the vehicle on the highway. It stopped working with no warning leaving our family stranded in the lane with heavy traffic all around us. The steering wheel would not move the car would not go in neutral and there was a burning smell coming from the hood. My kids were terrified. We had to wait for state police and a tow truck while praying that the cars behind us would stop in time. We are very lucky there was not an accident. The car is with the chevy dealer now.

My vehicle went from completely fine to having a loud knocking noise while I was driving 65 mph down the 4 lane highway. My vehicle lost power and slowed down. I was 50 miles from a dealership. They had to replace my entire engine and crankshaft. It cost over $12,000. 00. This exact issue has been recalled by gm, but websites say my vehicle is not covered.

6. 2l l87 engine failure with 36,000 miles on it. While driving on the highway and attempting to pass another vehicle that was traveling on a 2-lane highway the car suddenly died, and the transmission shifted into neutral. When I noticed the vehicle would not accelerate, I looked down and saw the push to start warning and tried to restart the vehicle with no response. I had to allow the vehicle I was passing to get ahead of me before I could swap back into that lane to get out of the way of oncoming traffic eventually coasting onto the side of the road to a complete stop. The vehicle I was passing slowed down after the engine died not knowing what I was doing and drove right beside me blocking the lane until I signaled for them to go ahead so I could get back into the lane. If the vehicle in the oncoming lane had not slowed down to allow me time to get back into the proper lane a head on collision would have occurred. This 2023 vehicle was purchased used 14days prior from a gm certified dealership and had no warning lamps on the dash and showed no indication a failure was about to occur. The vehicle was driving perfectly normal until the failure occurred. Once the vehicle was towed to the dealership it was determined the engine had failed due to crankshaft bearings. The dealership explained there were no available replacement gm engines and could possibly be a lead time of 6 months before a replacement engine could arrive. I purchased the vehicle for $60,000 and the engine fails 14 days later and now I could be without a vehicle for 6 months and the dealership did not have any loaner vehicles available.
