There is an electronic problem that continues to trip the warning for the Air Ride suspension system to fail leaving the vehicle stuck at its current ride height or it drops eithee the front or rear suspension to the ground while simultaneously raising the front or rear to its highest setting. It also causes the vehicle speed to drop immediately to 56 mph.

This is a huge safety concern as well as a huge financial concern for the consumer.

My 2021 Chevrolet Suburban stalled while driving in late September 2025 and had to be towed to a dealership. The vehicle is subject to an active fuel pump power control module safety recall that has been in effect since 2021. The vehicle was brought in specifically for repair of this issue. The work was processed under warranty, and I was charged a deductible. After learning the repair was directly related to an active safety recall, I requested reimbursement of the deductible, as recall repairs should be completed at no cost. That reimbursement request was denied. I have since been informed that the recall repair was never “completed,” and the recall still shows open in the manufacturer’s system. I am now experiencing shuddering and symptoms consistent with a potential stall recurrence. The original stall occurred while I was transporting my children, including special needs children who require regular transportation to school and therapies. The vehicle failure left us stran

The front of the fuel tank is hanging down and nearly dragging on the ground. This was with normal driving on a highway. No hitting bumps or aggressive off-road anything. We noticed when we heard a scraping noise going slowly over a slight incline in a driveway that it was hanging down.

After purchasing the car, the engine oil low light came on after driving about 2,000 miles on a fresh oil change. We took the car to the Chevrolet dealer where they said the engine was over 2 quarts low on oil and recommended a fresh oil change. After another 2,000 miles of driving the low engine oil light came on again. We took it back to the same dealership and started the oil consumption test. After several months of oil checks, it was determined that the engine failed the test and service was recommended and would be covered under warranty. Extensive repairs were performed on the engine including piston replacement. After receiving the car back from repair, we continue to have the engine oil low life light appear after a few thousand miles of driving and have to add 2 quarts of oil to the engine. We contacted the Chevrolet dealership that performed the repairs and they said that prior warranty work would not be covered since we were now out of factory warranty. We were informed tha

On January 13, 2026, the engine in my Suburban failed suddenly and completely, rendering the vehicle inoperable without warning. The failure left me stranded with my children, creating a serious safety concern and requiring immediate towing. Prior to that day, the vehicle exhibited no ongoing symptoms, warning lights, or performance issues, aside from a ticking noise that appeared only on the day of failure. The vehicle was towed to an authorized Chevrolet dealership, where it was determined that the engine was damaged beyond repair and required full replacement. I was informed a new engine would need to be ordered, at an estimated cost of approximately $14,000—an extraordinary and unreasonable expense for a vehicle of this age and price point.

Engine is running low on oil all the time. took it to dealer they said, there is sludge build up. Found oil fouling on CYL 3 and and found Spark plugs with excessive oil no external leaks found recommend new engine

The car was driving at 60 MPH on a regular commute to work and the car was stalling and shaking and soon after the check engine light came on with multiple issues.

Vehicle experienced sudden engine malfunction including rough idle, hard misfire, and flashing check engine light. Vehicle was diagnosed with a collapsed lifter and internal engine failure. Metallic debris was found in the engine oil, including silver and gold/bronze particles consistent with bearing material. A Chevrolet dealer inspected the vehicle and determined that the engine requires complete replacement due to internal mechanical failure. Vehicle is equipped with the 6.2L V8 (L87) engine. The failure occurred without warning and presents a safety concern due to potential loss of propulsion. This vehicle is not currently included in the existing GM 6.2L engine recall, despite exhibiting the same failure characteristics reported in other affected vehicles with the same engine and year that were included in the recall. Vehicle has not been driven since metal contamination was discovered to prevent further damage

I have a 2021 Chevy Suburban with the L87 6.2L V8 engine. At 7k miles, we have lost propulsion, leaving the car undrivable. resulted in the dealer replacing all 16 lifters under a recognized bulletin. I never received extended 6yr 100k mile powertrain warranty as described in the bulletin. Since then, There have been 3 other issues with loss of propulsion, resulting in replacement of fuel pump modulator. belt pulley system, One of the incidents left us without power or control of our vehicle on the interstate, with no where to pull over or get out of the way of oncoming semi trucks. The last incident again left the vehicle undriveable at 84k miles, with the dealer currently reporting that it is a lifter and cam shaft issue. Resulting in a 10k bill. They state that it is not covered under the recall of these engines because it is the top of the engine versus the bottom. Clearly, the engine oil problem noted in the recall has contributed to these issues . and the cran
