To start, I've been pretty loyal to GM. I'm a self proclaimed fanboi. I've owned 5 cars in my 18 years behind the wheel, all GM (if you count a 2011 Saab 9-3 as being GM since it was developed during that time). Now, I have a 2018 Buick Regal Sportback that I bought new in December 2018 and now has 32k miles. The car has been fantastic. Everyone that drives it is blown away at how smooth and quick it is and I absolutely love the space inside. I just moved into a new office for my job and did much of the move with my Buick. My father went so far as to say it was the best car our family has ever owned for the money.
Fast forward to about three weeks ago, I was driving along uphill going about 30-40mph and the car downshifted on its own into first gear out of nowhere. The dash lit up and the car slowed to 10mph or so. I tried upshifting in manual mode, nothing. I coasted into a parking lot, called roadside. Car insisted I wasn't in park and wouldn't turn the ignition off (although the engine stopped). Dealership replaced the battery, said the transmission control module was failing but they ordered a new one and would replace it when it comes in, but to take it because it was working. That same day I picked it up, took it too work, when I went to go home, same lights on the dash. This time, I turned it off and on but it wouldn't restart. Called roadside. Dealership indicated this time it was going to be in for a long time while they wait for the master mechanic to put eyes on it. After a week, they had replaced a transmission valve body and reflashed the transmission control module (not replaced it, part still wasn't in) but said this was definitely it and they were certain of it. And the car worked for about a week so I thought so too.
Fast forward to this past Thursday, I had a meeting about 50 miles south of my office at 7pm. Got in my car and drove down and on the way back when I was on the New Jersey turnpike, this happened: https://www.youtube.com/watch?v=8SM8_hRxrbg. I was lucky because you can see in this clip, it turned back on while I was driving and I was able to steer and maneuver for a few seconds into the shoulder and then coast the car into a rest area. Mind you, this with no engine and no power brakes. Anyone whose driven on the NJ Turnpike knows how infrequently rest areas come up. I was beyond lucky. I'm also lucky there was no reason for a sudden stop because it would have been an accident.
Anyway, it was about 8:30pm at this point, I called for an Uber, cleaned my car out, left the key in it and called roadside. They wouldn't tow to my normal dealer so it's at a different dealer about 20 miles south of mine. I went to my own the next morning and made it clear this was unacceptable and I needed a replacement vehicle or a buyback because under no circumstances am I taking that car back. The young lady at the desk said she would speak with the dealership it was at and explain to them the situation, speak with a manager and call me. This was Friday. They are also open on Saturdays. Still no call. I called the dealership where it is and he confirmed no call from my dealership and he couldn't start working on it until I go and sign paperwork. I explained to him the situation and he told me "off the record" that I'd have better success getting it working temporarily and taking it straight to a dealership to trade in. He also asked for a chance to let his guys diagnose it. EDIT: forgot to mention that with each of these issues, the transmission was banging in and out of gear and the car has been shifting poorly since. There is definitely some damage to it
Long story short, we've lost trust in the vehicle. There's no way my wife is going to let me take the kids in the car now that winter is here. My work takes me long distances a few times a week and these Uber rides are getting annoyingly expensive. I went car shopping yesterday and I'm ready to pull the trigger on a CPO Volvo S60 but I don't know what to do with the Buick. I am an attorney and can probably fight and threaten suit to get the money back, but to be honest, it's a douchey move and my business is seeing an unusual peak right now and I don't really have the time. I just need a reliable vehicle. I don't mind taking a haircut but I also don't feel I should have to because the Buick is high miles and has a few scratches on it.
So like the title says and long story short, is it worth trying to fight for a buyback from GM? Or do I just take a couple thousand dollar haircut and just trade it in and write it off as a mistake?
