Continuing failure of rear lighting (back-up, brake, driving, and turn). Typically, I have to replace a bulb about every 6 weeks, and the entire left assembly has been replaced twice since the car was new. Bulbs and sockets melt until they are inoperable. Similar issue with front headlights, although only about once a year. Old bulbs and assembly disposed of, but I'm sure more melted ones will be available soon.

I have two problems: when driving at night, headlights go off, not way to see, other than put on brights. Rim, broke to small pieces, had just gotten off I 95, was on off ramp when the car started making a very loud and scary noise, we had two small children onboard . Had this happen while on I 95 we could have all been dead.

Headlights become inoperative when driving: when driving at night the headlights stop working I have been forced to pull over and wait until the lights become operative. I have discussed this problem with my local dealer and he stated that there was know visual reason that he could find on why this was happening he advised that I should bring the car in the next time it happened, this presents a problem because if the lights fail in the day light hours I wouldn't be able to see the failure only at night can I visually see that my headlights have failed. The headlight failure can last for minutes to hours I have been driving on the highway at 65 MPH and my headlights completely fail.

My 2003 chevy trailblazer has a third brake light across the top hatch .while driving down a busy highway it was flying like a wing on the back of my vehicle luckily dot falling completely off but when I stopped it came crashing down onto my window of hatch luckily not breaking all I could do is break it completely off so it would not fly into someone's windshield behind me I work with a lady with the same make and model and hers flew right off her latch causing it to smash luckily no one was behind her. I also have it in the shop due to rusty corroded hoses that went to transmission causing all fluid to drain almost burning up my transmission no indication lights ever came on other than it skipping a little luckily a service engine light came on a week later I took it to garage and just in time. Unfortunately even with power train warranty this problem is costing me 500.00 out of my pocket no fault of mine wheel wells and brake drums have been beaten due to lots of rust build up and doors that were recalled and fixed three times still not working right also front headlight replaced twice in two years causing me to be pulled over twice as I did not realize the problem of my lights going out frequently.

My right front headlight was burned out, and upon investigation, I discovered that the plug and bulb socket had melted along with several inches of wire. It was repaired after some back and forth discussion with the chevrolet dealer. I thought this incident was strange, but thought it was a random incident until I read on a web forum that this appears to be a common occurrence.
