I bought my 2003 Chevy Tahoe used and as is at a dealership for $10,000. Yes, I've been robbed. The truck is in great LOOKING condition. Has a little bit of superficial dings and a couple dents but overall exterior is great. Interior isn't shabby. Has wear on the driver's seat but not bad. The first thing that happened, I was on my way to work at 4 in the morning, turned on right blinker to change lanes, about blinded the guy in front of me with high beam lights. I thought I had bumped the switch, I took the right to get off at my exit I was more mindful. Definitely not a me thing. The high beam came on with the right blinker. So, the next thing. CD player runs continuously without a disc in. I cannot put a disc in. There may be discs already in there, it is a 6 disc changer, but it will not play. The radio has a mind of its own. Plays what it wants at anytime its on. …

My wife and I purchased a new 2003 Chevy Tahoe on March 17, 2003 from a Chevrolet dealer in novato, california. Approximately 10 months ago the speedometer began registering 60 MPH while the car was not moving. This eventually changed to 120 MPH despite the fact that the car was not moving and the engine was turned off. The speedometer never registered anything below 120 MPH thereafter. We finally had to get it repaired as we never had any idea at what speed the automobile was actually traveling. We took it to the same dealership where the car was purchased to have it repaired. We were advised that the instrument cluster panel had to be replaced as there was no other way to fix the problem. This cost $359.88. When I asked to see the broken speedometer I was told it was not available as it had to be exchanged for the replacement. …
Recently purchased (3 days ago) a 2003 Chevrolet Tahoe and both my wife and I noticed erratic behavior from speedometer. After much research and another family member with the same problem on a 2004 Tahoe, we realized that this was a serious safety issue that an extreme amount of other people were having. The speedometer "sticks" at different points while accelerating or decelerating, I wish to get this issue resolved as soon as possible via recall. GM is well aware of this problem and it should issue a full recall on the instrument cluster to fix the problem. A simple "special situation" warranty is not good enough. GM must issue a recall on this very widely experienced problem. They also said that although my mileage was only 2000 miles over the "70,000" mile mark, they wouldn't fix it. This is a serious safety issue! GM...do the right thing! …
Driving on interstate when speedometer began to act erratically. Slowly but surely speedometer went from cruising speed up through the 120 mark on the vehicle and remained fully pegged in the black portion of the gauge. All driving now requires drivers judgment on speed since speedometer is inoperative. Speedometer can settle as low at 40 MPH, but quickly sky rockets again once driving commences. No corrective actions could fix the speedometer malfunction. Not knowing the speed of a vehicle presents an inherently dangerous situation and screams negligence and liability. Force Chevy to fix this before someone dies and they learn the hard way.
I own a 2003 Chevy Tahoe! My speedometer just stop working one day when driving. It will stick on a 120 or 35 or sometimes it wont move at all. I do have a picture of being parked and Tahoe shut off and its showing 120. Something needs to be done..people can't afford tickets for going over and under snd I also have the tow pkg and own a pop up and really scared to travel with it. Cant afford the 600 they it will cost..cant get into a non Chevy. This is my first Chevy I bought and think it will be my last. .GM step up and get this recalled.
At 43,000 miles my speedometer got stuck and will not work. At park it reads 80 or 20. I bought my Tahoe new with only 10 miles and now it is 3 years old. I called a dealer and he said that should not have happen to a new vehicle. When I am driving down the highway I look and it says that I am going 60 then a second later it reads that I am going 120 and it is stuck. This is not safe for anyone and I have heard other people complain that there Tahoe did the same thing.
2003 chevyrolettaho. Speedometer not working correctly. At times the speedometer will register speeds that are between 20-70 MPH in excess of actual speed, and at others will register speeds that are 10-40mph below actual speed. Other times the speedometer appeared to read correctly. Operation is jerky at all positions. The actual speed was unkown since this instrument cannot be trusted. This has been happening off and on every couple of days for 5 months.
