The "Service Engine Soon" of my wife's Nissan Xterra came on. I took it to All Star to perform an inspection. They call me a couple of hours later to tell me that the gas cap was loose which send the signal to the computer and turned the "Service Engine Soon" light on. These days is hard to find honest people like the folks from All Star. I am not saying that all the mechanics are dishonest but unfortunately, there are many out there that would take advantage of the situation to rip people off. They could easily tell me that it was some kind of sensor and charge me a few hundred dollars for it. I really, really appreciate their honesty. If you need a GREAT and RELIABLE car service shop, look no further.
