Since December 2020, our Suburban has been in for seven extended, documented dealership repair events at Guaranty Chevrolet and Simpson Chevrolet of Garden Grove, totaling 192 cumulative days out of service and $47,560.86 in documented repair invoices — approximately 71% of what we paid for the vehicle. Those repairs have included a complete transmission replacement (58,861 miles), a recurrence of the same active-lifter defect only ten days later, an ignition coil failure, fuel injector and air conditioning failures, an oil pump failure, and, most seriously, a complete engine replacement (66,854 miles) after the dealership documented metal in the oil and filter and engine end play. The situation has continued to worsen. We picked up the vehicle on XXX following the complete engine replacement. Only six days later, on July 6, 2026, the check-engine light returned and we brought the vehicle back to the dealership. We were initially told the issue was a sensor; the following day, we were informed that the replacement engine — which the dealership had disclosed to us at the time was a refurbished unit — was itself defective and would need to be replaced a second time. As of this writing, that repair remains open. In other words, the remedy provided for this vehicle's most serious failure did not resolve the problem, and we are once again without our vehicle. This pattern of failures has caused real, ongoing hardship for our family. We specifically purchased a full-size, top-trim Suburban for its seating and cargo capacity: we have two teenagers at home who depend on us for transportation to school and activities, we regularly care for grandchildren, and our [XXX] daughter has Complex Regional Pain Syndrome (CRPS), a debilitating condition that often requires her to use a wheelchair. The Suburban's cargo space is what allows us to transport her together with her wheelchair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving yesterday when my car began to shake at low RPMs. The traction control light came on steadily and the check engine light was blinking. I was unable to safely accelerate. I took it to my mechanic who tested spark plugs and coils, which he confirmed aren't the problem. He informed me that this is a common issue with the GM 6.2L engine, but mine isn't part of the recall. After checking online I see that this is exactly what many others are reporting and that there's an the federal safety agency investigation as well as a class action lawsuit tied to this issue.

Two years ago, we had to have the transmission rebuilt after it kept slipping. Yesterday, as I was driving on I-95, I was passing a vehicle and pressed on the gas. There was a loud crunching noise and I lost acceleration. The check engine light came on right away and I couldn’t press on the gas without a noise and limited forward momentum. I then had to maneuver the car across four lanes of traffic with limited control over speed. There was no warnings an issue was going to occur. We had it towed to our mechanic who said there was low compression in cylinder 1. Less than 90 psi. Again, we had already had the transmission replaced and now this major engine issue. We are in the process of getting it to a Chevy dealer.

Statement of Incident and Repair Costs While driving on the expressway at approximately 70 mph in the express lane with my family in the vehicle, the engine suddenly began to stutter and run rough. Within seconds, the vehicle lost engine power, the oil light came on, and the check-engine light started flashing. The sudden loss of power caused another vehicle to almost collide with us from behind, narrowly missing my family when our truck slowed abruptly. Because of the immediate danger, we were forced to cross two lanes of interstate traffic to reach the shoulder as quickly as possible, putting my entire family at further risk. We were then stranded on the side of the expressway. The vehicle was taken to the Chevy dealership in DeMotte, Indiana. Their diagnosis determined a catastrophic engine failure caused by lifter failure, resulting in bent rods and damage to the camshaft. Despite widespread reports and known issues involving lifter failures in this model, there is no recall for this year and model. As a result, we were left to cover the full cost of the repair. The dealership did not provide a rental vehicle, even though this truck is our family’s only means of transportation large enough to safely haul all of us. Insurance would not cover the failure due to the numerous notices and documentation showing that GM/Chevy is aware of this problem but has not initiated a recall. Total cost of repair: $8,801.53, paid out of pocket. Of which we had to borrow and scrape to figure out how to pay for it, due to it being our only vehicle for our family. Now we are left with the uncertainty as to whether the same thing will happen again, endangering the lives of our family yet again, due to living out more in the country and having to drive 30+ miles one way to get to grocery stores etc… on roads that have a speed limit of 55mph rt 49 going north from south of the Kankakee river or the expressway again where the other incident occurred I65 by Lowell Indiana exit.
