“80 miles into a weeks vacation my engine light came on, car was still drivable, backtracked 20 miles to dealer, left my nice car (11,000 miles)there for the week while using a rental car with 177,000 miles on it. Problem was pertaining to campaign 953 engine problems. A wiring harness was put in, and the dealer updated the software that had been updated that march, and they said that was all fixed. I have watched the video on this campaign problem, and it scares me where I cannot take my car out of town/on vacations out west! If this engine fails, I wouldn't always be able to get to a dealer. …”
