I was told by accurate that my wipers needed to be changed so I had them done. When I showed my old wipers to my brother-in-law, he said they didn't need to be changed. Accurate also recommended that my car battery be changed so I went back to the Toyota dealer that installed it. They looked at the receipt of the test that was done and they said that the battery test done was incomplete and that my car battery didn't have to be changed yet.
