Time will tell. My son had his oil changed there on Thursday, Feb 9th and then came home later that evening and parked in the driveway in Sahuarita. On Saturday, I was looking at the tires because the service rep indicated they needed to be replaced (they have at least 20k) more miles when I depth checked them. I noticed a significant oil leak. I crawled under the vehicle and found that the oil plug was loose and I was able to turn with my fingers. When I hand tightened the plug, I found that the hole had been stripped when they did the oil change. Nothing was ever said and thankfully I found the issue before he seized the engine. I've called American 5 Star and left a message as they close at 1 Saturday. I'll update the review with their response. ************* Owner took in car and fixed the oil leak. He was really good to work with, listened to my concerns and took care of my son. Thank you!!
