NHTSA Complaint #11492036 — 2012 GMC TERRAIN

First off before I got the car it had gone through a tune up. About a couple months after I got the car little things started to happen it would rock back and forth while idling I thought it was kind of an indicator that it needed oil but the percentage was still at a decent range and telling me it didn't need oil plus I hadent driven it 3000-5000 miles. Then engine light came on had it inspected codes ran came back telling me something about Throttle body So I purchased a whole new throttle body in Prosser at dealership costing me some booko buks and swapped it out when I got back home I then took it for test drive along with my 4 kids in the vehicle with me and then a little ways about 20 mins driving engine power reduced light came on along with stabilitrak and eventually lost power I was stranded in the middle of summer in the middle of nowhere with my kids windows rolled down ppl drove by and asked if I needed help and eventually came back with jumper cables tried to jump me but the car wouldn't budge I then left the car there overnight and took battery out to have it inspected the next day IT WAS FRIED (over 4 yrs old) so I had to purchase a new one costing me roughly 150 buks then took it back to where my car was stranded put it in and alarm went off and I clicked the button on key ring stuck it in ignition shit the door behind me locking keys in car while vehicle was still running and had to bust a window out to get to em. Got into car drove off made it back to my apt left it running outside while I went inside to get some stuff before I THOUGHT the problem was solved it shut off again.....I then had to replace the alternator costing me another pretty penny....about a couple weeks later I was starting a new job at a assisted living facility and arrived 10 mins early shit car off a noticed smoke coming from under hood I was confused because where the smoke was coming from couldn't have been it overheating I popped the hood and my car was on fire!!!!
