Just to let you know. GMC envoy, chevrolet trailblazer, buick rainier, oldsmobile bravada, saab 9-7x, isuzu ascender they are all exactly the same vehicle that has just been rebadged. I personally drive a 2004 isuzu ascender, and I can't get GM , chevy, or isuzu to fix it without charging me $475. My tachometer always reads wrong. My speedometer sometimes reads wrong and my gas gauge does not give me the correct reading. This can be real dangerous. The speedometer issue is more wide spread than you guys think.
