I brought my vehicle in for a check engine light and it was there all day and they called me to try to sell me a car battery that I did not need. They stated there were so many codes going through that could not test accurately. Diagnostics did not occur in this case. Well, from being ripped off from another shop I put red tape on my computer plug in with plastic between the prongs enabling a cord not to be plugged in without removal. Well, after I got home and over a $100 dollars later I found the tape and the plastic never removed. Honesty is not true in my experience but ripped off and violated with an awful taste in my mouth. Another shop 15 minutes diagnosis and replaced a fuel regulator. been 6 weeks, no light and running perfect. big disappointment and it is ok to own another battery than an interstate.
