I would've given this a really awful rating if it happened while driving. There is something wrong with these cars, this year. The thing shut off while waiting at the bank in park, twice. This is the first time it's happened, but now I'm scared to death and should be. Others are saying their 300's shut off while driving!!! I really hope that doesn't happen to me. This may be related to the heated seats also not working??? Both things happened at about the same time, both in very cold weather. Please let this be a cold weather problem, but playing around with it seems stupid or at worst, deadly. What is it going to take for these car manufacturers to wise up and either fix the problems or make better vehicles?? I LOVED this car. Too bad it might kill me and my family... I'm literally so scared to drive this on the highway or even really over 25 miles an hour now. What a great car for the money... I guess if it seems too good to be true it is!! Anyone with any helpful comments, please contact.
