2022 CHEVROLET SUBURBAN Complaints

I own a 2022 Chevrolet Suburban (VIN: [XXX] ) that is included in NHTSA Recall No. 25V274 / GM Recall No. N252494000 for engine defects in the 6.2L L87 V8 engine. My vehicle was inspected at an authorized GM dealer today, on 9/23/2025 (Don K in Whitefish Montana). Instead of replacing the engine, the dealer performed the recall “remedy” of switching to higher-viscosity oil, changing the oil cap and filter, and providing an owner’s manual insert. However, the dealer service manager specifically told me that my engine will eventually fail due to the known defect and advised me not to drive the vehicle on long trips. He also told me to be careful driving if I have children, and it is only a matter of time before the engine fails, which will look like sudden shuttering, loss of acceleration and it will no longer run. He told me wait time to get a new engine after it fails is currently 8 months. This is alarming because the recall notice states that engine failure can cause sudden loss of propulsion without warning, which could be catastrophic going across multiple lanes of highway (from my home street), and entering and exiting my street via the 4 lane highway "suicide lane". I am very worried about this in the coming winter season with snow and ice. The current “oil upgrade” remedy does not resolve the underlying manufacturing defect in the connecting rod and/or crankshaft. Even after the recall service, my vehicle remains unsafe to operate, and the dealer’s own warning confirms this. I request that NHTSA review GM’s recall remedy to ensure that it adequately addresses the safety defect. A true remedy should involve replacement of the defective engine components, not just an oil change, or an immediate buy back of my automobile by the company so I can purchase another safer vehicle. My family and I do not feel safe driving this vehicle, and the manufacturer’s current approach does not eliminate the risk of catastrophic engine failure.

Engine Coolant Control Valve sticking and causing the fan to run continuously. (P1098). Seems to be an issue with several people.

The motor on this vehicle has been on recall since April of 2025. Several phone calls and a cancelled appointment by the dealership has netted a consistent "we have no information and aren't ready to fix the vehicle." Today, I was directed to the NHTSA to self-monitor when my vehicle would be ready for repair or inspection. Meanwhile, I drive a Suburban because I have five children that I am constantly transporting to school, sports events, scouts, etc. I have grave concerns over an engine failure while I am transporting my children and the risk of an accident.

The coolant control valve malfunctioned on this vehichle several times during the course of ownership. It causes the vehichle to run in limp mode. This part was replaced in July 2023 at ~40,000 miles as a result. The part again began to fail in june/july 2025 with a dealer visit and diagnostic in July. This causes a check engine light, reduced milage, reduced acceleration, constant fan running and fails state inspection Google searches indicate this is a very common problem, yet no recall has occured to date. The first repair was in warrantee and now the vehicle is out of warantee. If the part was not covered under the vehicle warrantee, the part and repair would have been covered by the part warantee. Becsuse of the initial powertrain warrantee repair, the part warrantee does not apply. This is clearly a defective design and part that requires recall and replacement at GM cost

Coolant control valve failed and needs replaced. Which left me and my 3 children (one being [XXX] ) stranded on the side of [XXX] for 2 hours before someone could get to us. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving down to Florida, No warning, no lights, never any issues except a belt replacement. I get oil changes, tire rotation every 3500 miles. Almost got killed doing 75 miles per hour, engine sputtered, totally shut down. Coasted onto an exit ramp thank God it was right there or we could of been killed. Tow truck towed to Davis Chevy Gainsville, they called me on Monday said good news I have a warranty bad news Total Engine Failure, will take 3-4 weeks to replace. Now I am trying to find a GM rental large enough to get me and my family back to TN since GM said they will only pay for a GM rental car. Scary, could of gotten killed. NO NOTICE FROM GM ABOUT ANY POSSIBE PROBLEMS....WE ALMOST GOT KILLED AND CRASHED along with the other drivers on the road. Thank God it was a Sunday and 6 am so not much traffic or it would of been worst.

Our 2022 suburban with the diesel motor has had 3 separate incidents where by all accounts the wheels have locked up while driving. The incidents mirror what has been described in the recall N242454440. The first time the incident occurred, we were driving while towing a light load (boat ~2500 lbs) at a steady speed of 60 mph. While driving the vehicle shook violently once, and then again about 2-3 seconds later. I immediately pulled over suspecting that maybe there was an issue with our trailer. After finding nothing we drove home without incident. Shortly after this incident we had the transmission flushed for regular maintenance at about 50,000 miles. Approximately 5-6 months later the second incident occurred. While driving with no trailer, up a mountain in NC at a steady speed of 35 mph, the vehicle shook violently and then again approximately 2-3s later. Each time the vehicle shook a loud "BUMP" noise would be heard. The road was smooth and was later driven on without issue so it was not the terrain. I once again got out and inspected the vehicle and was unable to find an issue. We drove to where we were staying and immediately took the vehicle to a dealer the following day to be inspected. The dealer found no issues and we did not report any similar problems. The last incident occurred after another 8 months while towing a light utility trailer at a steady speed of 60mph. Same thing happened with a shake and loud BUMP. However this time it was not followed immediately by an other instance. Those came approximately a minute later and then again after about 10 more minutes. I cannot recreate the issue and it seems to be at complete random and is happening while driving steady rates of speed where the transmission shouldn't be trying to shift. It seems like a safety hazard that could cause an accident.

The contact owns a 2022 Chevrolet Suburban. The contact stated while driving at various speeds or while accelerating from a complete stop, the automatic emergency braking system engaged while there was no other vehicle nearby, and the vehicle skidded. The contact stated that the traction control warning light was illuminated. The contact stated that while her husband was driving at an undisclosed speed in the rain the failure reoccurred, causing the vehicle to skid. The vehicle was taken to the dealer, where it was test-driven, but the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 89,000.
