2017 Chevrolet Suburban: engine failure

Filed Jan 17, 2026 · Engine, Transmission · CA

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.

I purchased this car at CarZone in Riverside This April 2024. I drove home with my kids in the dark and people kept honking. The lights and turn signals did not work. I took the car back in. The back up camera was broken, the safety system is broken, brakes are bad, they put two bald and all four tires with gummy plugs after I brought it back a fourth time. The tires were not fixed. I found out driving on the highway with my daughter. My tires popped. I had to pay for all four to be replaced and the dealership will not take any of my calls. I then had a check oil light. I took the car in. Pep boys discovered they had replaced the oil hose with a different one. It backed up into the engine. I paid for an oil change and was told to keep an eye on it and contact the dealership. They would not respond. I went back to pep boys be my car was completely out of oil one week later and my headlights kept dying and the car wont accelerate. They did another diagnostic and contacted the dealership and warranty saying it needs a new engine entirely. They sent an adjuster who said nothing was wrong and closed it. I have had to take the car back since. The liftgate is zip tied to the tail pipe. I am terrified to drive this car, especially the head light and brakes. I bought new tires bc the dealership would not help even though I have all the text messages they sent about the issues. It no longer accelerates the way it should and I have to put three quarts of oil minimum per week to keep it running at all. I am out so much money that I do not have and I cant drive an unsafe car with my babies in it. Upon further investigation I have found this dealership has done this to many people. I just need help getting them to take this car back or pay to fix it and to make sure they are following safety laws. I feel responsible to report this because I know I wish someone else had and it would be absolutely devastating if someone got injured in a vehicle sold by them.
