Yep, I just spent $1,700 replacing the pump & brake booster last week. 2 weeks before that, dropped another $1,700 to replace cracked HVAC condenser & compressor. And in January the HMI for the touchscreen sh** the bed for a whopping $1,800. I do have 80k Highway miles on the truck but they’re gentle miles & the interior still looks/smells new. I have an ‘04 Sierra with over 200k on it & only had to replace an instrument cluster. I logged a complaint with NHTSA on the brake issue, so hopefully I’ll get reimbursed for some of that cost soon, but not holding my breath. For $50k, these trucks sure are temperamental.
