If I would've gone with 1st stop autohaus, I would've poured nearly $7,000 down the drain to replace working parts and STILL ENDED UP WITH ALL THE SAME PROBLEMS. I brought my car to get any issues checked out and repaired due to a check engine light. They told me a $125 diagnostic fee would be charged for the time their technicians would inspect the vehicle and then "tell me EVERYTHING they found wrong with it". They then said that if I did decide to do any work from the diagnostic, that $125 would be applied to the services. They had me then write down any concerns I had in particular on a single line of paper. After several days, they said that the only things wrong with it were the two to three things I had specifically mentioned. Not only that, but everything I mentioned was "completely broken and needed to be replaced" quoting me nearly $7,000. No pressure testing, no dye test for leaks, nothing. Just a drive down the street and a peek under the hood. They also cleared the codes before even checking them, completely failing to quote me on the one faulty part that was causing the check engine light in the first place (since the light didn't come back after they cleared the codes so they had no clue what was causing the issue). Maybe if they checked the codes before clearing them, they might've gotten a clue. Then, they told me the $125 diagnostic fee wouldn't apply towards any of the services less than $300 since they were more of a "routine maintenance", despite them being part of the diagnostics. Not only that but my "routine maintenance" oil change (which was due) was nowhere to be found on the "diagnostic". Basically the $125 could only be used for the expensive repairs, not the cheap ones (despite what they said at the start). I took my car to a different shop where they told my they would have to pressure test and leak test before doing any work. Come to find out NONE of the repairs that 1st stop autohaus had "diagnosed" my car with even needed to be done. The only thing that was on their diagnostic that actually needed to be fixed was the one part that I HAD TO REMIND THEM TO PUT ON, because they failed to read the codes to discover it was faulty before clearing them. If I would've gone with 1st stop autohaus, I would've poured nearly $7,000 down the drain to replace working parts and STILL ENDED UP WITH ALL THE SAME PROBLEMS. The owner explained that even though they charge $125 for a diagnostic, they can't waste their technician's time looking around for problems with the car. At best, your car will get around an hour to be checked out, so they really only investigate the concerns you write down. If you don't know what is the issue with your car, don't take it here. They'll give you a good glance under the hood and make up some problem based on what they see. It's like going to the doctor for knee pain and having him diagnose you with a total knee replacement without even taking x-rays. Complete scam artist shop. I'm sure they take down the bad reviews though, so I doubt this will even stay up. Beware! SAVE YOUR MONEY AND AVOID THIS SHOP.
