The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving 25 MPH, the vehicle was shaking and jumping and shut down unintendedly. The check engine warning light illuminated and was flashing. The vehicle was towed to the local dealer where it was diagnosed that there was catastrophic engine failure and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed there was no recall on the VIN. The failure mileage was approximately 104,000.

My Suburban is having the same issues as the most recent recall on the 2021-2025 Chevrolets. The issue is with pretty much all of the motors that go from the V8 to the 4 cylinders. It's doing the same exact thing a friend of mine's 2019 Tahoe did. It's making a loud knocking/ticking noise. When you first get to going it starts almost sputtering which can cause issues if you're in oncoming traffic trying to cross roads.

ENGINE, FUEL/PROPULSION SYSTEM
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.

Driving on the highway and I started to slow down even while pressing the accelerator. Pulled over and turned the car off and then back on. I was able to almost get to an exit but then it completely stopped moving. Turned it off and on again but car would not move. Not a single light turned on until the last time I attempted to move the car. Had it towed to Chevy dealer and transmission was completely out. Had 2 different mechanic places (dealer and private) tell me that it is extremely common once a 2020 suburban hits around 100k miles. That is completely irresponsible of GM to not put something out so that owners can at least have knowledge that there could be a potential problem. No warning signs, no lights on that is an accident waiting to happen and a potential wrongful death lawsuit coming your way if something isn’t put out.

ENGINE, UNKNOWN OR OTHER
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.

Without warning my 2023 Chevy suburban started making a terrible noise, lost all power and died in the middle of the road. I was unable to restart the vehicle. It was towed to the nearest dealer 75 miles away and has been sitting there for 30 days with no idea when an engine will be available.

Brand new 2023 suburban radiator ruptured at 14,000 miles. Radiator and hoses replaced April 2024 and the car has ongoing issues since then. Most recently the car has a strong coolant smell and the dealership states they cannot find a leak or source of the smell. I have worked with 2 different dealerships on this matter. I was told that the radiator was a “poorly manufactured part” when it originally ruptured. No safety warnings ever appeared even when the oil was dripping out of the bottom after the original rupture. Oil and coolant had mixed in the coolant reservoir and no warning light ever signaled. The most recent coolant smell poses a safety risk to my families respiratory system as the manufacturer states they cannot find the source of the smell and have tried to return to vehicle to me twice with the strong odor coming out of the vents. We have had the coolant reservoir flushed several times as oil remains in their, hoses replaced, and ongoing service visits for a year for the same thing since the original rupture in April 2024.

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.

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.

SUSPENSION
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.

My sub starting making an unusual banging noise when shifting. I reported it once to the dealer and they chucked it up as cause by the vechioe being driving in auto and not set to 2 wheel drive or 4 but instead auto. Was odd, but it still happens and now there a recall but the site does not include my vin even though maybe this is my problem.

My engine had a defect which required the entire engine to be rebuilt. The engine lifters, push rod and crankshaft all failed and I had to incur a $9000 repair. I believe this is in line with the current recall of Chevy 6.2L V8 engines like mine. I believe this is defect of Chevy's that they should be required to reimburse.

On January 29, 2025, while my wife was driving our 2022 Chevrolet Suburban with a 6.2L gas engine on a state highway, the vehicle suddenly lost acceleration and power to the wheels while accelerating to the posted 55 mph speed limit. This occurred without any prior warning, creating a highly unsafe situation in morning commute traffic. The vehicle was immediately taken to a Chevrolet dealership, where the issue was diagnosed as a failed transmission control valve. This failure, which resulted in a complete loss of power while driving at highway speeds, is a known defect affecting certain GM models. The part in question, the Transmission Control Valve, is currently in high demand and is on a national backorder due to numerous similar failures. A recall has already been issued for diesel engine models with the same problem, but no recall exists for the gasoline-powered versions like ours. Chevrolet has confirmed the diagnosis and is aware of the issue, but the replacement part is currently on a national backorder, and the repair has been delayed indefinitely. Since the incident, the vehicle has been undriveable, causing significant inconvenience, and Chevrolet has been unable to provide an estimated date for repair. The sudden loss of power created a dangerous situation on a busy highway, as there were no warning lights, messages, or symptoms prior to the failure. This is particularly concerning given that the part involved is on backorder due to the widespread nature of the issue. Chevrolet's lack of a clear repair timeline, coupled with the fact that this issue has been identified in other models, raises questions about the company's response and whether a broader recall or safety bulletin will be issued for vehicles like ours. The vehicle’s failure has not only been a major inconvenience but also a safety concern, highlighting the need for urgent attention to address this defect.

The Infotainment center display is black and therefore unable to utilize backup camera. The screen is still sensitive to touch but does not display anything for any function. Primarily a safety risk for backing up a large vehicle.
