Defect Description:

ELECTRICAL SYSTEM

Potential Consequences:

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.

SUSPENSION

Potential Consequences:

I bought the vehicle on January 11, 2025. Within 2 weeks the service leveling system indicator light came on the dashboard. The vehicle's front left air suspension system was not working properly and the vehicle lowered to the crash shield. The vehicle would not go over 55 miles and hour and was bouncing all over the road. The vehicle went back to the dealership and they reset and calibrated it. A few weeks later, the same thing happened. The vehicle again went down in the front, and was unsafe to drive. The dealership had the vehicle for 3 weeks, had difficulty assessing the situation and changed the front left air suspension arm. They told us it was fixed. We picked it up and as we were driving it home the service leveling system indicator came on, we brought it right back. They had the vehicle another 2 weeks and changed the solonoids, reset and recalibrated and had us pick it up. Within a few weeks the same thing happened, but worse. As I was driving it, an explosion sounded from the vehicle and the whole entire front of the vehicle lowered to the crash shield, making it extremely unsafe to drive. I have asked for the dealership to get a certified mechanic from GM to come and look at the vehicle and to start the repurchase process, no one is getting back to us and the vehicle is unsafe to drive.

ENGINE

Potential Consequences:

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.

ENGINE

Potential Consequences:

While attempting to regain entry onto a major highway, our engine had a major system failure and the entire vehicle started to violently shake. We were able to reexit the highway and get to safety. We were then able to slowly drive it to a service station where it was determined after two days, that it was a major engine failure and would need a full engine rebuild. We were in Missouri when this occurred, driving back from Christmas vacation with family, on our way home to Texas. We had to find a hotel and stay two nights there, then had to rent two cars- as there were no cars available large enough for our family of 6 and our luggage, to then drive back to Houston. We then had to have our car transported down here to our mechanic. The repairs that our mechanic completed: BTR Gen V DOD/AFM Conversion Kit $1301.75 Full synthetic oil change and oil filter $110.00 Prestone Dex-Cool 50/50 prediluted antifreeze/coolant 2@$33.23 ACDelco GM Original Spark Plug 8@$20.32 GM Spark Plug Wire Set $142.44 GM Camshaft $200.04 Cloyes Engine Timing chain tensioner $44.54 Standard Ignition Manifold Absolute Pressure Sensor $47.85 Head Gasket, R&R $5010.00 Labor Oil Change $110.00 Labor Computer Programming $2000.00 Labor (reprogramming needed to shut off the Fuel Economy Management system that caused the camshaft to ultimately break) Total $9434.29 We were without our car for 4 months while this repair was conducted and the subsequent computer programming was problem solved. We learned there was a case already with your department, but waited to file out claim until we had the full repair and receipt from our mechanic. We could not afford to just sell the car as we would have gotten so little for it. Thus we didn't have much of a choice but to get it repaired. This week we are hearing of the massive recall of many GM vehicles, ours included, for this same problem. We are hopeful that we will get some sort of financial return to cover what we paid to fix their issue.

We were in Missouri when this occurred, driving back from Christmas vacation with family, on our way home to Texas. We had to find a hotel and stay two nights there, then had to rent two cars- as there were no cars available large enough for our family of 6 and our luggage, to then drive back to Houston. We then had to have our car transported down here to our mechanic. The repairs that our mechanic completed: BTR Gen V DOD/AFM Conversion Kit $1301.75 Full synthetic oil change and oil filter $110.00 Prestone Dex-Cool 50/50 prediluted antifreeze/coolant 2@$33.23 ACDelco GM Original Spark Plug 8@$20.32 GM Spark Plug Wire Set $142.44 GM Camshaft $200.04 Cloyes Engine Timing chain tensioner $44.54 Standard Ignition Manifold Absolute Pressure Sensor $47.85 Head Gasket, R&R $5010.00 Labor Oil Change $110.00 Labor Computer Programming $2000.00 Labor (reprogramming needed to shut off the Fuel Economy Management system that caused the camshaft to ultimately break) Total $9434.29 We were without our car for 4 months while this repair was conducted and the subsequent computer programming was problem solved. We learned there was a case already with your department, but waited to file out claim until we had the full repair and receipt from our mechanic. We could not afford to just sell the car as we would have gotten so little for it. Thus we didn't have much of a choice but to get it repaired. This week we are hearing of the massive recall of many GM vehicles, ours included, for this same problem. We are hopeful that we will get some sort of financial return to cover what we paid to fix their issue.

POWER TRAIN

Potential Consequences:

History of transmission shifting issues shortly after purchase (CPO from Dealership). Vehicle was taken to two separate dealerships, several times for this issue while still under the 100,000 mile CPO warranty. Dealerships claimed they could not replicate the issue, however problem continued. Now at 1198xx miles, the transmission failed while driving. was accelerating from stop and and the vehicle bucked, the rpms jumped, the service indicator illuminated, and when the vehicle stuck in limp mode. I spoke with one of the dealerships and explained the history and suggested my vehicle failure was exactly as described in the safety recall and they informed my VIN was not included in any recall or service campaign and the could do nothing for me. I called the GM customer service number, pled my case and was told the same thing

VISIBILITY/WIPER

Potential Consequences:

For the past 2 years my windshield wipers will fail randomly while using them during a rain storm. I will have to pull over and completely turn the vehicle off turn back on and they may start working again or restart a couple more times. I’ve taken it to the dealership twice over it and the one time it was when they didn’t work and no codes showed up. It just happened again while on the turnpike during a rain storm. It’s very scary because some roads you can’t pull over right away and It’s very hard to see when the windshield is completely covered and the wipers won’t work. A major safety issue. I wanted to take a video but it’s not safe when I’m driving and trying to see out the window. I have 2 little kids and currently pregnant so this is very scary with my kids in the car.

ENGINE

Potential Consequences:

Chevrolet is telling me my engine has failed at 75,000 miles. While driving on the highway recently I lost all power. I had my 3 kids in the car and was driving at highway speeds on a crowded highway and lost all power. I had to move over to the side of the road while in neutral with no power. Once I was on the side of the road, I was able to then turn the car off and turn it back on. I then drove to the nearest exit to get myself and family out of harms way. The car then began making a significant loud screeching/knocking noise. I have video of this noise. Ultimately was towed to a dealership where I am now told that the car needs a new motor. Additionally, I regularly service my vehicle at the Chevrolet dealerships with on time oil changes as soon as the car says I am due. Twice since owning, my car has been so low on oil that I have to immediately add oil in between oil changes. Car is currently at the Chevrolet dealership and has not been fixed at this point. The vehicle has only been inspected by Chevrolet service tech at the dealership. No warning lights or other symptoms, besides the oil issue have ever occured with this vehicle. Please help!
