As a service manager of an independent repair shop, I am appalled at how many members have horror stories of dealing with professional repair shops. Perhaps I can give a few pointers from the other side of the counter that will ease the stress of choosing a shop to do your work.
First of all, be familiar with the laws and agencies in your state or province that pertain to the automotive trade before the excrement hits the rotary screw device. Knowing your rights and your responsibilities to be able to preserve those rights gives you a leg up on an unscrupulous shop operator. Here in Alberta, we are accountable to a government body called AAMVIC. Most jurisdictions in North America likely have similarly legislated groups. By doing your research in the middle of a dispute, you may have given up some of your rights already.
Ask around. Your friends and coworkers probably know of an honest shop that does good work.
Ask questions at the shop. What are their warranty terms? Do they have the latest software in their scan tools? Do they subscribe to database services such as Identifix or IATN to get help diagnosing really oddball problems? Do they call for permission to proceed before doing any work? Do they use Mitchell or some other time estimator or do they just “wing it”? Are their technicians certified and fully equipped with the tools to complete your job? Do they have an ongoing training program?
Let them do the diagnostics. I don’t know how many times guys have come into the shop saying the problem is “A” and after running on the rabbit trail they created we find that the problem is “B”. Guess who pays for that time? My worst case scenario in that regard was a new customer who came in and said another shop had said the transmission in his Ford diesel was pooched. He did not want us to diagnose it, just change it out for a remanufactured unit. After installing a $3000 H.D. automatic transmission, the original problem still existed. What the truck had needed was a $400 solenoid pack. He felt that we had ripped him off because we did what he contracted us to do, but he was too cheap to have us diagnose it which would have saved him thousands of dollars.
Let the shop supply the parts. Whoever supplies the parts supplies the warranty. You may think you are beating the system by using your lower priced parts, but shops have suppliers and reps they use consistently because when crap happens, those suppliers and reps step up to the plate. I have been able to get warranty on out of warranty parts from suppliers and reps that I have a good working relationship with. If you supply the parts, unless you can prove an install problem, all costs are yours.
Pay the workman his due. My lead tech has tools and toolboxes worth around $100,000! He has over 25 years of experience. The automotive trade is dying. Last stats I saw was that the average age of a technician was 51 years old and for every 2 that retire, only 1 is entering the trade. Because of this, shops are competing for qualified techs and the wages are going up to get techs.
One last thing. You do not have to take your car to a dealership to maintain your factory warranty. Any qualified shop can maintain your car. If the shop you choose subscribes to Mitchell, IATN, or Identifix they can often tell you about “secret” warranties that the dealer won’t mention.
Post any questions. I’ll be glad to answer.
