While traveling back from Labor Day Weekend on [XXX], I was driving in the Dallas Fort Worth area when I experienced loss of power to our vehicle on a major highway [XXX] and [XXX] ) and directly on a bridge with my entire family in the vehicle (4 kids and all of our luggage). It was a very dangerous and scary situation. We had to wait one hour for a tow truck to come and take my vehicle to the closest GM dealership. I was left stranded, 3 hours from my home with my four children and luggage. The Chevrolet dealership contacted me 9 days later and informed me the technician looked at the vehicle and determined the engine was locked up/seized. It would take 9 months to get the vehicle back into the shop to determine what caused the issue and then take 6-12 months for a new engine. I have a family of 6 and I'm left car-less for two years. Yet I still have to make the monthly payment on a vehicle that I won't be driving or be in possession of. MY BIGGEST ISSUE: GM has known that they have had engine issues for many years. Particularly, with Dynamic Fuel Management causing lifter issues which leads to engine failure, yet never disclosed this to me when I purchased the vehicle. Furthermore, they never disclosed that the issue was so prevalent that motors were back ordered for over a year. Consumers are being misled into spending their hard earned money on vehicles that have major mechanical design flaws known to the manufacturer. Once the mechanical flaw is realized, the vehicle can't be repaired for up to two years. Hiding this data from consumers should be criminal. Furthermore, General Motors to this point has been no help, with the GM customer satisfaction team telling us they can't do anything until a dealer diagnosis the issue, and the dealer stating they can't diagnose the issue until May of next year, at which time they would then look to order the motor which will take 9-12 months to deliver and install.

- Truck makes a sizzling sound when parked - Car wouldnt start and needed battery jump, unknown source draining the battery - Truck has engine issues, started shaking and died in the middle of the highway, GM replaced engine - Engine replaced after less than a week, truck would not start, Gm replaced starter - After 2 days and using the vehicle once, truck would not start again. GM is trying to root cause issue but cant find a resolution Since the car stopped when we were on the highway and none of the fixes seem to be working I am worried that the car will abruptly stop again and put my life and others at risk
