Over the past month my car has been in the shop four times due to it malfunctioning while I am driving it - and that is not including when I took it in at the end of August because the trunk merchanism broke and it wouldn't close. The first time happened over labor day weekend when I was on a roadtrip, out of nowhere the car would not accelerate and, like others on the nhsa website have stated, it was very jumpy and wouldn't go past 45 mph. I took it to the dealer where they replaced a safety recall in the wiring system and it worked fine for a few days before it had the same problem again. When I took it to the dealer the second time they told me the engine needed to be replaced because the engine was essentially broken and there were little metal pieces inside. It took a week to replace and then everything was fine for a few days until yesterday. Yesterday the battery light turned on and the repair shop let me know the battery was in good health but low on charge so they charged it and it seemed to be working fine. Then this morning while on the highway all of the emergency service lights (check engine, check brakes, etc. ) came on at the same time and the steering wheel locked up and it was undrivable. I by some miracle managed to pull the car over where I had to get the car towed to the dealer where I am awaiting to hear what is wrong. Do not purchase this car. After reading up on it apparently there seems to be issues with the engine and electrical system, that is extremely dangerous. I was lucky enough to not hit anyone but I could have been seriously injured all four times the car malfunctioned. All of these issues have been confirmed by the dealer to have been due to manufactural defects - something that is out of my control and shouldn't happen for a car that is under 26k miles.
