Hey, everyone. I'm looking at a 2014 SXT that is for sale at a local dealership. It has 58,000 miles, looks great, and the Carfax shows routine maintenance. I test drove the vehicle today and it wouldn't go over 40mph or 3500rpm and the check engine light came on while I was driving. Took it back to the dealer and he drove it and had the same issue and said the mechanic would fix it. Other than this issue, the car is great and a good price. Is this a problem anyone else has experienced and fixed? Could this be something that happens often if I buy the car? Thanks in advance for any advice.
