Two western states have made their auto repair protection efforts available in the form of pamphlets that can be accessed online. The California Bureau of Auto Repair, whose actions has been the subject of a number of All Car Advice posts, publishes a Consumer’s Guide to Auto Repair. It can be viewed online at the link at the bottom of this article.
There is some information that is specific to California, like how to file a complaint, but the bulk of the brochure has a lot of helpful hints on how to stay out of trouble at a repair shop. How to find a reputable shop and what to do when you are describing your problem are dealt with in detail. You can request it to be mailed to you subject to availability. The instructions are contained in the link. The material, however, is not conveniently printed from the online version.
Washington State’s Attorney General’s Office has prepared Auto Repair Before and After and makes it available online as well. It outlines what is illegal in the state and while not applicable to your situation it does bring up some disturbing practices that are good to know about. Low balling and getting paid twice (by the consumer and by a warranty company) are examples.
Especially helpful are points that are made in both of these publications. They are to find a repair shop before you need one and to know your rights prior to a problem arising due to a failed repair to your car. As has been stated before, the law can be the ultimate trump card when negotiating an auto repair problem.
