The component or system failed was the transmission 4 different times. A new transmission was put in the car just 6 months after purchasing from a dealer. The transmission lasted close to 3 years being shy only a few days before the transmission warranty expired. So a new transmission was provided by the transmission owner at no additional cost for the transmission but we had to pay $1600 out of pocket for labor. That transmission lasted for 2 months before failing again which caused us to have the truck towed to our home to decide what our next step would be. So we had it towed to Tire max and they put in another transmission by the same manufacturer which we only had 2 days left under the warranty. That transmission failed within 2-3 days so we took it back to a different Tire Max location and they put in another transmission which did not cost anything for us by the manufacturer including labor. This transmission has now been in good standing since 12/20/23.

The first issue is popping coming from the front end of the vehicle causing a steering issue. This has been "repaired" multiple times with no resolution. Every time the popping occurs which is almost every turn the steering wheel will not turn. The next issue is the radio is causing driver distraction by changing stations and screens not just on the display itself but the instrument cluster as well. The radio has been replaced once due to the fact it was on backorder for 6 months another attempt has not been made. The third issue is the brakes have failed at slow speeds no warning lights were on, they just stopped working in the Mcdonald's drive-through. I had to get out of line to keep from rear-ending the person in front of me. Now, after that experience, the ABS light has come on and the service StabiliTrak flashes on the dash as well as parking assist off, everytime I hit the brakes. .

I began to hear what sounded like loose rear suspension components about a year into owning the truck. I took it in for service and was advised that per the gm service bulletin, they re-torque the leaf spring bolts. It was fine for a couple of months, then the noise began again. It's now been to the dealer 4 times with 11 days out of service. The response continues to be, they've re-torqued the bolts to gm specs and nothing else they can do. It's very clear by the noise that can be heard, both while moving forward and backing in, something is not within specs. The truck is under warranty and I am a couple of months over on lemon law arbitration. Gm is doing nothing to address what could easily be a safety issue and I'm concerned that the bolts continually need to be re-torqued. I've taken to online forum searches to find that this is a common problem with a similar tap dance done by gm. It's shameful that consumers are buying a $40k to $70k truck and having these issues with no solutions being provided through the truck warranty. And when the warranty runs out, how expensive will this be? Not to forget, dangerous. I am concerned that one day, the rear-end is going to come out from under my truck and hopefully it's not while on the highway with my daughter in the truck. My truck is used for my daily commute to and from work. It's well maintained, not abused and has under 20k miles. I've turned to bbb for help and was offered 2 years of oil changes by gm. Oil changes don't fix the problem!

The rear leaf springs pop and groan while the vehicle is in motion at low speeds, especially while turning in reverse. Gm knows about the problem and every time I go to them they say it's normal.
