No I had em do some work on my brakes and every time.id come in they would tell me I should get struts. Multiple times so I caved in. But not before I ran it by them that the sub box is back there. And got the all clear. I've been putting in complaints with corporate daily and never receive a call back except once some lady names SJ who was rude and just repeated that they said my sub box is to blame and I should remove it. Nobody cares that I ran it by them BEFORE HAND... :/ I have a open credit card charge back against them because I didn't think of small claims and technically I didn't get what I paid for. They also claim I had another shop work on my car but actually all I did was have another mechanic test drive my car for 5 mins and his conclusion is these struts are junk
