I used to get my oil changed here at Precision Tune quite frequently. I was beginning to trust them with my car, so I decided to let them do my tire balance and wheel alignment. The lug nuts on my car were a different size than the air wrench that they used to tighten them, which lead to them stripping the studs on my car. Before the mechanic finished with my car he asked me what wrench I used to tighten my lug nuts. I told him that I had a tool in my trunk that he could use (after he already attempted to tighten them). A month or so later, I had more wheel work done (from a different company) and they told me that 5 of my studs were stripped. I took the initiative and BOUGHT more studs and went back to Precision Tune. I explained to them that the mechanic who worked on my car stripped the studs. Management reviewed my car and said that it was only possible that they could’ve caused damage to one of the studs. So instead of guaranteeing their work and taking responsibility for all 5 studs, they only took responsibility for one. One of the managers even asked if I had my brakes done since I was last there because they "recommended" it to me the last time that I was there (which in turn, he was trying to put the blame on someone else). Hadn't had any brake work done. They did however knock off maybe 50 dollars and said that they would throw in a tire rotation. After getting my car fixed, I asked another employee if there was any way to avoid this from happening again if they accidently stripped the new studs this time, without them saying that someone else stripped the studs, since obviously they didn't take responsibility (only way you will know if the studs are messed up is if you have to have more wheel work done). He explained to me that usually the mechanic is supposed to report any problems that he encounters and that the mechanic that worked on my car no longer works there because they were having problems with him. However, I still didn't receive a definitive answer. They will no longer receive my business.
