I took my 2000 Ford Super Duty to TSI for a diagnostic check. My truck would start and run fine, but would not restart after the engine warmed up. I was informed that it would cost around $4,500 to fix, and was given a laundry list of things that they said were wrong with my truck. I was told that the injectors needed to be replaced, it required a new wiring harness and the fuel system also needed replacement. After I told them that I could not afford to pay that much and would have to bring my truck back at another time to have the work done, I was then informed that it would no longer start. They charged me for work that I never consented to have done and left me with a truck that no longer functioned. They had resealed the injectors, and at some point did something to make my truck inoperable. I was charged $1,141.00. Only $197.00 of the bill was for the diagnostic check, while the rest was for work that was never approved by me. This also included a charge of $202.00 for an ICP sensor that I had replaced before I brought the truck to them. It even stated on my bill that the sensor was replaced previously, and I was still charged for it.
I was told by Mark that the owner was out of town, and that he would contact me about refunding some of the overcharges. I never received a call from him. I tried calling them to talk to someone a minimum of 10 times. Every time that I would call, I was told they were on a conference call and that they would call me back.
After looking at several reviews for this company, there seems to be a trend of people being overcharged or being charged for work that was never performed.
