I can understand your concern with your situation. I would have to agree with ls973800 about the warranty information he has provided to you. If the technicians diagnose this as something that will fall under the Powertrain warranty you should be covered. However, you will want to find out the expiration date of the Powertrain warranty. It seems that you are good with the mileage, but you might be out on time frame. If you are out by time frame, find out how long ago it expired.cjozwiak said:
