Got my AT4X in January '23. First 10 months were awesome, since then it has been a disaster! The telematics module has been replaced multiple times now. All 16 lifters were replaced in May, then the engine seized up 2 weeks later. Full engine replacement was required at 25,000 miles. The only thing worse than dealing with all this is working with GM customer service. Seriously those guys are a joke!
