2005 Chevrolet Trailblazer: whining or grinding noise

Filed Jun 28, 2018 · Brakes, Electrical · OH

I have a 2005 tb ls, and it's a pos. As soon as I drove off the lot I've had nothing but issues. My brakes pulsate, go to the floor, get stiff as a board, basically they don't work. I have to pump the brakes quickly in an effort to avoid a crash. I filled the gas tank to full, huge mistake. The moment I did that the check engine light has flashed and sporadic idling. It has a loud whine under the hood, front turn signals and hazard flasher randomly stopped working. Car will die if I run the A/C for more then 15 mins. It will pull to either side when I apply my brakes. I have always kept up with proper maintenance, tune up, etc. This is absolutely terrible, that so many have the same [xxx] issues and yet chevy will not recognize/take responsibility for their obvious flaws and lack of mechanical knowledge..I just want out of this [xxx] lease and a replacement car!!!

My 2005 trailblazer with only 28,000 miles started whining loudly, the lights flicker & the heater turns itself on. A repair shop said it may need a new alternator. Of course, chevy only put a 3 year warranty on it & this all started happening 1 month after the warranty expired.

I have had my 2005 trail blazer for 2 years, and have taken it in 3 times, and had the alternator replaced twice. I'll be taking it in again tomorrow, due the dimming/flashing lights, and whining noise. Same symptoms as before, alternator again I'm sure. I am hoping to sell it, and never buy chevy again. Very irritating!

I own a 2005 chevy trailblazer. Since purchasing this vehicle I have had several problems. I am the second owner. I bought it with 24,000 miles. The first thing was the engine light turning on for no apparent reason. Tests would show nothing. Then the whining started. This was fixed at the dealership. Next the flickering lights. It only seems to happen at night (or that is when I notice them). When the flickering started the lunging started. This is when I am coming to a stop or going slow my car seems to jump forward for no apparent reason. The dealership found nothing wrong with my car when they checked these problems out. Next when making u-turns my car would just die. Since it is an automatic I would have to then put it into park and restart my car. Again when I took it to the dealership, they found nothing. My speedometer has started to jump or fail to work altogether. And most recently the engine light turned on again and and my car was running as though it was going to die. Upon taking it to the dealership, they ran $500.00 worth of test to tell me that my car at 60,000 miles was firing incorrectly in the 1st cylinder. This is going to cost me $4,000.00.

I purchased a 2005 chevy trailblazer on 4/15/05 shortly there after I was having problems with a whining sound. I took it to a dealer and I was told that it was the ignition pulley. I contacted the corporate office of chevrolet to inquire about assistance with payment considering I was about 3, 000 miles over the warranty. After several calls chevrolet absorbed this cost. Then in sept. Of 2005, my husband totaled his car and I purchased a 2005 trailblazer for him. Again this car began making similar noises and my husband was driving home with our 2 year old son and the car began smoking. My husband immediately pulled off the road and contact roadservice. Once we took it to a mechanic he said that it was the ignition pulley which caused the transmission to die. We took it to a chevrolet dealership and they said that was the transmission. I contacted the corporate office once again and this time they would not offer any financial assistance. It seems that the dealership said that it was the result of an oil change that did not occur at the 3000. They, the dealership based this off of a sticker that was in the window of the car. When I went to look at the car they was no oil sticker in the window. Despite that, I had contacted the chevy office about the same whining noise that I heard in my car (the ignition pulley) that my husband was experiencing in his car. This is still not resolved. We were told to fix this car it would cost $10,000.00, yes, for a new transmission. We have since towed to home in order to avoid storage fees. Here sits a 2005 chevy trailblazer with approx. 50,000.00 and a new transmission is needed. We do not have the money to fix this and also pay the car note on it as well. As a read reports, this is a similar problem with many many trailblazers. There needs to be a recall on this vehicle for faulty transmissions!!!!!
