Transmission jerks with hard shift and rough idle

- Stanton, MI, USA

I was driving on the interstate and then all of a sudden my vehicle started shaking while driving and by the time I got home in less than 15 miles, the truck was producing huge clouds of smoke out of the exhaust. I took it to a dealership and it was determined the lifters were bad, less than 6 months after I paid off my vehicle and the extended warranty expired. In repairing the lifters it was determined there was a misfire in cylinder 6 which in conjunction with the lifter failure, it damaged rods and pistons to such an extent full engine replace was deemed necessary. I had every maintenance and inspection done on time since the purchase of the vehicle by a local Chevrolet dealership and there apparently was no warning or concern that my lifters were going to imminently fail and/or cause extensive engine damage. My truck was in the repair shop for nearly a 1 year while I waited for a new engine Chevrolet agreed to pay for half of an engine even though I was out of warranty by a few months, but I was under the mileage on the warranty by 30k miles. The truck was not heavily used. Most miles were highway interstate miles from long road trips, but the vehicle largely sat undriven most days of the week for a couple years leading up to the engine failure.

Entire system (everything) shut down without warning, sometimes kick back on, and other times not at all. Extremely dangerous as it will occur no matter traveling on highway or turning a corner in a parking lot. There are discussion boards in which many people have experienced this problem and clearly it is because of "Bad Battery Cables" and common within the 2014-2018 models. My truck is currently in a dealership garage to have the cables replaced and I have to have a rental car while the cables are on backorder for 5 to 10 days (maybe longer). How is this not a "recall" when so common and so dangerous? Dealership could see in a diagnosis that power had been lost and communication lost, over and over and over. There has never been a dash warning light come on at all.

GM has produced millions of vehicles with the 5.3 motor with AFM, DOD, VVT issues. They are well aware of this issue. The factory defect causes the lifters to collapse causing catastrophic engine failure. This posses a hazard to consumers in traffic trying to navigate their stalled vehicles off the roadways. GM customer service is rude and dismissive, furthermore they offer no assistance to fix these problems. The issues with these motors is well documented and any repair shop/ dealership can confirm these issues. There is no indication from warning systems prior to this failure. However there are multiple Dash warning lights after the catastrophic failure occurs. The cost is passed to consumers to address these issues.

Upon light acceleration of the vehicle, a rough gearshift occurred followed by a check engine light and the vehicle continued to shift roughly and idled roughly. After months of diagnostic work and attempts at repairs, it was determined the lifters were the issue. From independent research I understand this is a somewhat common (and pricey) issue. I-??m not sure why there is not a recall for the cheap lifters, but I would like to pursue possible reparations for this fault of GM that has left me without a vehicle and left me with a great financial burden for over six months.
