Bought the car in mid Oct 2021. It has been in the shop since Thanksgiving. We have replaced the brake pedal position sensor, all coil packs, computer (twice), and the yaw sensor due to these codes being thrown when the traction control would go off, service stabilitak comes on, reduced engine power, jumpy, hesitant, and limp mode. It would randomly clear up the issue and drive fine for a few hours. Then back to the same. Just received a call from the Buick dealership that it is saying now it is the fuse box terminals. This is something I am having to pay out of pocket as "replacing a fuse box terminal is considered normal car Maintenance".

Shocker, the car is originally from California. All in all, this has costed me over $2,000 for a something I have only been able to drive for 45 days... DO NOT PURCHASE THESE VEHICLES FROM 2008-2019 MODELS.

I purchased a 2014 Buick Enclave in May 2016. I started having issue last year with the engine hestiating and jerking and the engine light can on. The codes showed that the Catalytic converter and oxygen sensors replaced. The hestiation and jerking continued but the engine light went out. I have been so frustrated with this ever since thinking about getting rid of it but really can't afford to right now. BUT I am dropping lots of money into it trying to figure this out. Yesterday, the car started to really jerk, engine light on,Stabilizer light came on, running extremely rough and it said service the traction control and almost stalled on the road which was a dangerous situation. I took it to the dealer last night. He is saying there is low voltage going to the fuse box. He says he needs to replace the fuse box, all fuses and cables which is causing all these problems. I am skeptical until I read on here that others are having the same problems and there is a class action lawsuit. What should I do to see if this classifies under their same problems. I don't see a recall listed.
