Selected complaints filed with NHTSA by 2002 Chevrolet Tahoe owners, lightly cleaned up (personal details are redacted by NHTSA).
This vehicle was leaking oil from the engine, front and back brakes were faulty, the starter was going bad, the electrical system for the back windows were not in working condition. The vehicle would display sensor lights to have the vehicle engine checked but then after about 2 days it would not show a displaying message it would also effect the audio fuse that allows the audio system to function. The tires were bald on the front driver side and left back passenger side. The seat belts were difficult to enter into latch in order to secure seatbelt.

2002 Chevy Tahoe with 105, 000 miles. Changed spark plugs and found a severed exhaust manifold bolt on the engine. The bolt is from the driver's side end of manifold. The bolt is worn and rusty on 90% of it and the other 10% is shiny (like a new break). Called dublin, ca Chevy and went in after they said they have had many complaints. The offered to fix it for 10% off the $1000 bill. I told them that it was their defect and they should pay. I called gmac and they told me to goto another Chevy dealer in san leandro, ca for a diagnosis since the 1st dealership never looked under the hood. That dealer looked at the truck and told me that they would have to remove the manifold and it would cost approximately, $500, but it could run more if there were more bolts that break off during the repair. I have three young children and I have taken immaculate care of this truck. …
I ran out of gas on the freeway going 65 MPH with my 5 year old son in the car. Apparently when a Chevy Tahoe runs out of gas it shuts down the entire electrical system including power steering as well. I'm unsure of this ------> but it seems like the brakes are affected too. I had a very difficult time merging over to the right hand shoulder of the highway (I had to cross three lanes and merge with on-ramp traffic), given that I had very little steering control and had to use as much momentum as I already had to get off the road to safety, without being hit by someone traveling over 50mph. Plus other cars were not letting me over. I can see this becoming a very dangerous situation. GM just recalled a bunch of Tahoe years for this issue but not my year (2002). …
I had a brake failure on my 2002 Tahoe after driving at hwy speeds then coming off the exit to stop; the, service brakes light came on. I then attempted to brake and the pedal went all the way to the floor making it very difficult to brake.. , could have been catastrophic, and or deadly; I drove home 2 miles away, very slowly; I had very little brake control.(two infants in the car at the time) two out of four brake lines completely rusted with a hole; brake fluid leaked out quickly at time of incident ..like hundreds, and thousands of other complaints of same exact problem. The brakes themselves are fine., . To replace all four of my brake lines , it cost me $858($813 w/coupon). Recall id # 05V379000 - service brakes, hydraulic:antilock May address the problem if you get to it done before the lines completely fail. Applying rust inhibitor to your brake lines May also help. …
About 2 years ago I noticed engine coolant on my garage floor. After investigating I found that the leak was coming from the storage reservoir rather than the radiator. I also noticed that my windshield washer fluid was also leaking onto the garage floor. I took my Tahoe into a dealer. I explained the problems, they conducted their evaluations and I was then told that it would cost approximately $450.00 to repair both problems. I could only afford to fix one problem so I chose the coolant leak. They "fixed" the leak...for about $250.00. The coolant reservoir leak reappeared several months later. The Tahoe was then out of warranty and apparently to fix these issues it takes lots of time and expertise. These problems are becoming expensive and continue to be annoying. …
I have a 2002 Chevrolet Tahoe. Once the vehicle sets overnight or a period of six hours or longer the following problem occurs: I go to back out of my driveway in reverse the vehicle engine will die. Note that my drive way is on an incline. This cannot be recreated if the dealership attaches a tech tool to the vehicle. This problem can be recreated without fail with nothing attached. I have also had one occurrence that after I started the vehicle back, which it will always start back, I was attempting to pull out on a major road when the vehicle appeared to try and stall out. Luckily the vehicle picked back up and responded normally just a second before I was nearly struck broadside by a semi-truck. The date below is approximately when the problem started.
2002 Chevrolet Tahoe. One owner vehicle, bought new. Flutter/rattling sound when accelerating with air conditioner on. Does not rattle when compressor is off. Rear air stopped blowing cold. Mechanic states several people with the same problem. Replaced tensioner pulley. Belts. Still rattling/ loud. Now states compressor/condenser need replacing before seizes up. Mechanic states this is a know defect of this model, but not aware of recalls. This needs to be addressed since it seems to be a mechanical defect.
Tl - the contact owns a 2002 Chevrolet Tahoe. The contact stated while driving approximately 60 MPH, the vehicle stalled without warning.

The vehicle was not repaired. The approximate failure and current mileage were 187,000. Rk updated 04/17/14 the consumer stated the ignition cut off while driving. Updated 05/20/14
The exhaust bolts are breaking causing the exhaust to leak. The related problems will likely be poor fuel economy, increased emissions and potentially failed emissions test. The catalytic converter was already replaced on the same side as the exhaust manifold with the broken bolts. Problem was not noticed until the second bolt broke thus not sure when the original problem occurred. The problem appears to effecting numerous other vehicles thus a potential large global impact.
