 I have a 96 chevy tahoe. it has 37,000 miles and is, therefore, just outside the 36,000 mile bumper to bumper warranty. i have talked to several other chevy truck owners and they tell me that chevy trucks have a problem with batteries. though the battery is rated at 72 months, it only lasts for approximately 24 months. i have asked two different mechanics at the chevy dealer (macpherson chevrolet) and they say that it is true - batteries only last about 2 years. they also admit that they replace hundreds of batteries, often repeatedly on the same vehicles. they also tell me that in their opinion it is a gm design defect that the manufacturer has chosen to ignore. i have now replaced the battery twice (this is the third battery in the vehicle). the first time gm paid for it under the warranty. the second time it was just out of warranty so i had to pay for it. i also had to pay for repair of a battery cable that leaking battery fluid had damaged. though the dealer admits that the 72 month warranty is printed right on the battery, they say that the warranty ends with all other warrantees at 36,000 miles. that is gm policy and they showed me a memo from gm saying so. i had planned to keep this vehicle for a couple of years. however i do not relish the thought of having a very unreliable vehicle when i travel for any distance, knowing that the battery may go dead at any time. by the way, when this happens, due to the all electronic nature of the engine, nothing works - the engine dies, the power brakes no longer work, and the power steering no longer works, even at freeway speed. in my opinion this is very dangerous behavior. thanks for your assistance, tom nickelsen

 My 3 year old nephew was able to get into his parents 1996 chevy tahoe and was able to turn the key to the first click (before the click to turn on the radio and power windows, etc.). then without touching the brake, the toddler was able to pull the shifter into neutral and the vehicle was able to move. the toddler either was thrown from the vehicle or was scared and jumped and was run over by the vehicle and killed. all models and makes of vehicles can do this with the exception of honda, toyota and 2001 or newer dodge vehicles. *jb

 Wiring harness has corrosion in it up near the firewall. appears that the wiring harness was defective (damaged) during the assembly process. corrosion on ground side of air bag arming circuit means that in a collision the air bag will not deploy. dealer says that this is not a warranty item. corrosion in the air bag arming circuit could also cause it to deploy when it should not, leading to an accident. isn't there unlimited warranty on safety systems and pollution control systems? *ak
