I brought my car in for cert. For change of ownership..it passed no problem. Took car back two weeks later they say it needs a ball joint...."If it does then how was it certified!". Second problem...I had a tensioner replace nine months ago..today they have to replace the altenator and they say the "tensioner needs to be replaced and the bolt is stripped "which they Did" and this will cost me an extra 1000.00..to re tap the hole after they drill out the bolt they stripped...How do you stop a big company like this? I have been taken advantage of at least that's the way I feel
