ENGINE
Was driving on highway and engine started to make a noise, performance and power were impacted, the engine service light appeared. Exited highway on near offramp, when on offramp vehicle engine stopped working. Vehicle is a 2025 Chevrolet Suburban with 6.2L engine. Dealer has stated engine is seized. Seems exactly like the current 6.2L engine recall for 2021-2024 model years that results in engine failure. Vehicle is 7-8 months old, and only has roughly 12,000 miles.

ENGINE
Sudden power loss on highway. Engine would not respond. We were fortunate to have been able to pull over to the side of the road but in an unsafe merging area. Vehicle restarted after multiple attempts, but engine would not exceed 3000 rpm causing unsafe speed on highway. Engine died again causing total power loss. I was able to coast down the hill to safely park out of the way of traffic. Tow truck was needed. Vehicle was towed to dealer where it was purchased. After inspection, the engine was confirmed to have failed. The dealer advised for engine replacement as part of the L87 recall. This engine was previously inspected less than 10,000 miles prior as part of the same recall, and the higher-weight oil had been used since per the manufacturer's recommendation. However the inspected engine appears to have failed regardless. This sudden loss of power happened about two weeks prior, with the driver able to pull to safety and restart. It was dismissed as a fluke since it did not occur for the next two weeks.

ENGINE, POWER TRAIN
Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

ENGINE, VEHICLE SPEED CONTROL, POWER TRAIN
Engine failed going 70mph on highway at 2k miles. Display said acceleration no longer available and app said transmission code was needing to be checked however once taking to dealer I was told it was an oil sensor then told there was shredded metal in my engine and I needed a full engine replacement. My car was in the dealership for over 50 days. I was pregnant and with two small children in the car when engine failed at high speeds. After my car was returned to me the engine overheated and failed again. The dealer claimed GM sent them an engine with cut hoses. I was 9 months pregnant when this occurred also on the highway going 65mph. GM refused to buy back the vehicle 3 times.

ELECTRICAL SYSTEM
The complete infoentertainment system went out within one week of purchase and has been in the dealership possession since. The dealer’s service department tried to perform updates on the system after the radio went out and it caused the whole dash to go completely black and they haven’t been able to get it to turn back on. The vehicle has been in the shop for 8 weeks now and no estimate when I’ll receive the vehicle back. Since the dash is black you can not see the speedometer, gas gauges, etc and it is not safe to drive without it having fully working electronic components. The dealer is next going to try and replace the radio but that part is back order indefinitely.

STRUCTURE:BODY
On the driver side adjacent to the fuel tank, improper drainage for the body frame caused severe rust. Over time the frame of the vehicle becomes a safety hazard and may cause the frame to crack or split resulting in loss of control to the rear of the vehicle.

AIR BAGS, SEAT BELTS
Car says "service safety restraint system" and airbag light comes on intermittently. Dealer won't cover under safety restraint warranty. They site TSB about a wire that GM made too short but are not sure it will fix it. This car has 42,000. We are worried the safety restraint system won't work and we carry 4 children in our vehicle. This should be covered and a safety recall.

ENGINE
After just getting our vehicle back on 12/11/25 from our incident on 11/9/25 when my wife was driving at 70 MPH on the highway when the engine blew the first time. Approximately 1300 miles later and 15 days after we picked up the vehicle when I was merging onto the highway the vehicle had a sudden power loss and a smell that filled the cabin. We were able to drive to the next exit and while the vehicle was idling it sounded awful. The check engine light started to flash along with the TCS light and the collision warning lights. After getting to a parking lot when called OnStar to tow our vehicle to the closest dealer. I have not received any updates yet but it is very similar to what happened the first time when the engine needed replaced.
