Recently reported EXTERIOR LIGHTING problems on 2003 Chevrolet TrailBlazer

This vehicle was purchased new in jun 2003. while still under warranty, various recalls were issued for steering, brake lights and rear hatch locking/handle assembly. since then, the vehicle has been a lemon. power steering pump replaced twice (first one i paid for, second independent and very reliable mechanic shop paid). next the engine cooling fan bearing had to be replaced. later, the transmission had to be rebuilt. i also had to get the computer checked and reset to avoid surging engine rpm and resultant speed deviations. reaching a point of frustration as never before, i wrote gm asking for consideration repairing the transmission and received no response. i know they received the email since i had a "receipt requested" feature activated in my office computer. i sent a second email stating i was aware of the email receipt and that i expected a response. no such luck. all these problems manifested themselves well before the 100,000 miles were reached. now at approximately 132,000 miles, i had to replace the exhaust manifold due to a crack, the vehicle has lost power on two occasions, the entire dashboard has gone to zero and back to normal several times and the latest is an engine noise that my very reliable, 6 year auto service provider has told be is related to the timing belt assembly/mount points and as it gets louder, the engine will be getting ready to fail. so, i read all these complaints today and felt like i could have summarized everyone's complaints and concerns. i am an accident investigator and have no doubt that this vehicle will go down in history as one of the most unreliable and dangerous cars ever built. shame the feds have not taken the extra steps to remedy the issues after so many complaints yet, they went after top selling toyota at a time when the american made cars were barely able to stay afloat. wonder? *tr

2003 chevrolet trail blazers, which have frequent failures in both tail lights, including brake lights, turn signal indicators and reverse lights due to faulty boards which do not apply enough tension to hold the bulb in place. the bulb does not burn out, it just becomes loose. this should result in a complete recall, not what gm has called a special policy condition. failed rear lighting is a significant safety issue that the nhtsa should deem as a recall. *ak

I have had to have my entire valve body replaced, of course after having to fight tooth and nail to have the relaiable big lot dealership fix this trailblazer. everytime it has a problem, they do all but call me stupid, and send me away, or say that when they drive it, it doesn't fail on anything.it must be my imagination. whatever. now my brake lights fail completely, and they've never heard of such. lol, that's funny because we almost rearended another trailblazer with no brake lights. no wonder that semi truck almost killed us. anyone ever drive in st. louis rush hour traffic, almost get killed, and then discover that you have no brake lights?gee, vehicles have brake lights for a reason, who knew? now the waranty is up by 3000 mi and i'm stuck with the bill. that's funny huh? anyone organizing a law suit? count me in. *ak

Since i bought this vehicle august 30, 2002 i have had to bring it back to the dealership on numerous occasions for several different items. i have had both the left and right brake lights gone out, the driver side head lamp went out, the air conditioner has gone out twice(four months apart), the driver side passenger window is inoperable(we have tried to get it fixed for almost a month now with no success) and the engine cooling fan was warped and the fan clutch malfunctioned. at this point we don't understand why they haven't just recalled the whole vehicle. luckily we have the 36,000 mile warranty still in affect but what's going to happen when it is up and the same problems keep recurring? *la
