general problems of the 2016 Buick Encore

I was stopped at a traffic light and began moving forward to make a turn into traffic. As I activated my turn signal and started to proceed through the intersection, the vehicle suddenly stalled and shut off without warning, causing an immediate loss of power while the vehicle was in motion. Another vehicle was entering the intersection at the same time, creating a near-collision situation. I was forced to restart the vehicle in traffic. The incident occurred within less than 250 miles of purchasing the vehicle. The vehicle had recently received an oil change and inspection. No warning lights or messages were observed prior to the stall. This event created a serious safety risk.

My car read that the side detection system went offline, shortly after every warning light on the dash came on and the entire car shut off going down the road.

In reference to this vehicle, I purchased this car from burns Honda in February 2020. I replaced the battery less than a year of having this car. I then had my engine light come on and my car was skipping, it completely stopped while driving. Several times, it jumped when I would go over 65 mph. I took it to the dealership that same night and they continued to tell me nothing was wrong with it. I have had electrical issues along with that. After back and forth for several days with Buick, they finally replaced the transmission. Fast forward to October of 2021, my engine light continues to go off and on and my car has been jumping on me.

Side detection system stop working do to rear sensor bracket under rear bumper,should be under warranty but dealer will not cover. Wife is blind in one eye should have working.

2/2017- purchased new 2016 Buick Encore at honolulu GMC in first 2 years- dealership replaced 4 batteries I have all stock items I haven't added/upgraded anything on the vehicle they said I had no warranty after 50,000 miles which was a lie after having to replace the battery 2 more times and water pump once successfully and not at their dealership. 1/2021 I found the original purchase papers, while deep cleaning car before taking in to be fixed elsewhere and then GMC admitted I had an extended warranty. Due to long wait times nearest appointment in 2/2021. 2/2021 took to fix a/c blowing warm, engine lack of and losing power (which we took in for this before and they said nothings wrong just needed an oil change or something, gotta find paperwork for that repair to be sure) and parasitic battery test they didn't do the battery test (of course they didn�t) they fixed the a/c but instead of using the warranty, charged me a higher diagnosis fee and never filed the claim, said the engine was due to subpar spark plugs we took back our car and replaced spark plugs with denso. There was still the same problems. 3/23/2021 now they're saying cylinder 1 and 3 spark plugs are stuck want to charge $2500 for full fix, warranty will cover $1300, balance is for gaskets and liquid refill. Note: no one changes the settings in a torque wrench in the middle of doing spark plugs. How is it only 2 are seized? they're lying I need a lawyers help putting this here in case any one else had similar. Multiple other issues in between these. I have video recordings of some of these instances and paperwork for each repair.
