2025 Chevrolet Suburban 1500 Engine Problems

“While driving we received a notification on our dash board stating “reduced acceleration drive with caution”. We had it towed to the dealership where they said we needed a full engine replacement. It took 22 days to get the vehicle back”

“We have 8,625 miles on our 2025 Suburban. We were going down the highway when began to hear a unfamiliar noise. We pulled over into an error to inspect and didn't notice anything under the vehicle, which we thought might have cause the noise. We put into drive and went less than an 1/8 of a mile and our suburban lost acceleration and stopped. It would not start and couldn't not be moved, until roadside assistance took it to a Chevrolet dealership. The dealer stated the engine seized up and needs to be replaced. …”

“Cause unknown, however, I have discovered that the engine in my Suburban, the Engine code LZO 3.0L Duramax, has damaged itself internally. I have been told that there is a large batch of engines that have this same problem, and the dealership I sent my car to has several cars in the same position. This problem is causing the engine to lock up or completely quit. This could be serious depending on when this failure happens. Currently, they are telling me that I am months away from getting a new engine due to a back order. …”

“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. …”

“The engine in 2025 Suburban (6.2L V8) has failed and the car is not drivable. It is currently in a Chevy dealership service department waiting for parts. The 2025 model is not listed under the recall. However it should be, I know of 3 2025 engines that have recently failed. I was passing a vehicle and as I took my foot off the accelerator the transmission shifted 2 times and then the engine shut off and the car was coasting. We had no indication that the engine shut off, just several messages on the screen. ( Press start button, and conditions not correct for shifting.)”
