My jeep was there for 18 days ...for a crank sensor. The tech I spoke to said they were waiting for the approval on the parts under warranty. After 18 days my family needed the car and I paid the cost out of pocket. This was a terrible experience. Now I'm out 300 dollars because the warranty approval took so long. I should be refunded this money if approvel goes through. I'll be waiting for my check . In the mean time I will be letting other potential customers know about all the headache and irritation of dealing with the service department.
