The hybrid battery coolant heater (part 68443445AC) was confirmed a problem, however the dealership wont review ANY recalls on my vehicle until I pay $1700 to replace that part. However, there are MULTIPLE incidents online showing this is a problem with this vehicle and should be a recall as this is obviously defective within the first 150000 miles. My car has roughly 124K miles, making it just outside the warranty coverage. Shortly before this lamp warning (check engine) came on my steering wheel started "sticking" making it hard to steer in a curve, causing me to veer off the road. Within 7 days of this happening, is when my check engine light appeared, throwing code POE15. The heat now also takes much longer to warm up- like 30 minutes longer. The dealership said none of the issues are connected, however after online research I have determined that is not true.

On Thursday, July 3, we were on our way out of town and had just gotten on a highway when I smelled something burning, saw smoke (we thought was steam at the time) coming from the hood and heard the engine making a grinding, or rattling noise so we pulled over immediately. My husband got out of the car to start to take a look when another vehicle who had just passed us backed up and motioned frantically saying "Your car is on fire!" So we got out and looked under the front of the car and sure enough, there was liquid spilling onto the ground and fire coming from underneath. So we quickly got away from the car and called 911. Another gentleman who had been going West also stopped to make sure everyone was okay and was also calling 911. Within 10-14 minutes the front of the car was totally engulfed in flames.
