2007 Toyota Matrix Issue
My husband drives a 2007 Toyota Matrix. It's an automatic car with about 160,000 miles on it. The car was driving fine, but when he tried to use it the next day the battery was dead. The fob wouldn't unlock the door, turn on lights, horn would not work etc. He jump started the car, but it would only work when the car was connected. We got a new battery for the fob just to make sure it wasn't a security system issue. So he was able to jump start it again and make it to Autozone and they tested the bad and said it was a bad battery. It wouldn't seem that off if the battery was bad because I got it from this con artist mechanic that destroyed my other battery when I last brought in the car for something else and then he tried to sell me a different battery which I ended up getting for free. So we bought a new battery thinking the other one was bad and the car was running so he attempted to drive to work and the car stalled about 5 minutes down the road. He was able to get it started again and come back home. He changed the spark plugs last night and the car seemed fine, but when he attempted to drive it this morning he said the car seemed to be shaking and really loud when he tried to use the AC. He turned around and came back. Any idea on what the issue would be? We are trying to figure out ideas so hopefully he can fix it himself before we take it a mechanic and possibly get overcharged or get work done that isn't even needed.
