Fell in Love! Now broken hearted...💔

Bought the used 2018 GMC Acadia SLE with the 3.6L V6 engine with just under 37,000 miles on the odometer. Made the puchase of the vehicle in April of 2021. Few months later while on a trip to Florida the engine light came on. Had it checked and found an engine timing belt warning. We have had this problem happen every time the brakes are applied with force and back on the gas pedal. The engine light goes off after 24 hours. Weird! During that same trip we went through a heavy rain storm and while looking into the rear view mirror I noticed water leaking from the top of the rear hatch door. Whenever it rains hard it leaks. WTH! While having an oil change done my mechanic suggested new brake pads. I just had them replace all the pads and rotors for good measure. $1400.00. Then sometime in summer of 2022 the shift to park warning started. July 2022 the battery needed replaced. New Battery cost $180.00. Late September 2022 with 65,500 miles the transmission started hesitating & clunking when shifting to 2nd gear. After spending $4600.00 to rebuild the Transmission. After the rebuild the shift to park warning still happens off and on. While changing the oil the bolt had gotten so badly stripped I had to replace it. Only $5.00 but after only 2 oil changes it's starting to be stripped again. Early 2023 the Center computer console electronics started going wacko. It constantly switches to different modes without touching the screen. December 2023 the air conditioner quit working, the temperature gauge stopped working and the Engine light came on. After finding the codes that explain the thermostat has failed. I had a 1989 GMC Sierra 1/2 ton and though it needed some repairs it lasted 30 years. I tried to make sure the mechanical things were always done. With today's trucks and SUV's and reading all the problems other GM owners are experiencing, I'm convinced that GM makes crap vehicles now. I will never buy another GM vehicle. I still owe $18,000 on this piece of crap and now I have to find a way to trade it off before it costs me more money. 🖕GM

Bad Shifter & Transmission from the start

My 2018 Acadia has issues with the shifter the first year I had it. It was replaced three times. That eventually lead into needing a new trans in 2023 with only 58k miles. There have been a few other little fixes here and there but for the price of the Denali, I expected a lot more.
