 We have problems with the running lights, dash gauges not working properly. now the engines is starting to idle roughly and make noises. we got a notice letting us know that there was a recall on a part that runs all of the dash gauges. some kind of computer thing. i went into the dealership and they told me my car had too many miles to honor the recall and i would have to pay for it!. lets see, we wait long enough for miles to get past 100,000 miles and then they don't have to fix all the vehicles. i can see another tahoe coming down the road and one of the running lights is always out. we have a 2003 tahoe. the dash coating started pealing and they wouldn't cover it being replaced. i had less than 60,000 miles at that time. they said that the extended warranty didn't cover this. the tahoe is shifting real rough at times and will speed up on it's own at times. this shifting happens at least once a day. the gauges don't work at all. (fuel,oil pressure, and sometimes the rpm won't work at all). *tr
