| 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 am being told now that the problems arise from the fluid containers rubbing against their mounting boxes which is creating holes in the containers. any suggestions? steve mullis *tr | |||

| The fluttering/grinding noise actually began around august '06. i had to drive without ac with windows down to survive the heat. i asked a local auto repair station about the noise, since it was out of warranty, and he said he had worked on several tahoes with the same problem. he said that the chevrolet dealership knew about the problem because they instantly told him what had to be replaced. they told him the average repair bill for this issue would be approx $1500 at the dealership. since then i have heard other tahoes with the same noise , especially at stoplights when they accelerate. not everyone can afford that kind of repair, and if chevorlet knows about this issue, why hasn't there been a recall. this is not the typical and routine wear like oil changes and tires. *tr | |||

| Flutter/rattling compressor like sound when accelerating. appears to be from a/c compressor. from my research, other owners have reported similar complaints. dealer say this is not a equipment failure issue.*ak | |||

| 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. *jb | |||

| 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 don't think i should have to pay for a repair when it is obvious by looking at the bolt that the bolt was over torqued when the vehicle was built. after much research, i have found thousands of complaints of this exact problem. they need to recall these vehicles and fix them. if i let this continue without fixing the problem, i will have a huge problem on my hands and it will be a safety issue. | |||
