Filed May 1, 2017 · Electrical, Transmission · 80,000 miles · CA

My key will not come out of the ignition I had to unscrew and remove the bottom of my steering to push the button also all of my instrument gauge do not work including the speedometer and all gauges so I never know my temperature or fuel level, oil pressure they all are not working properly my speedometer only works sometimes. Also my engine is runny rough and I hear a vibration and ticking. My check engine light is and I'm getting code saying theres a leak in the fuel evap system. I have searched the internet and everyone has the same problems with their 2003 trailblazers. Why isn't chevrolet recalling these problems its fustrating they want several hundreds of dollars I cannot afford

The federal safety agency action number : pe07014 occurred on my vehicle around november 2014. The problem presented as p0442 cel and odor of gas after parking in garage. Gm has indicated because the special consideration allowance has expired, despite the low mileage they will do nothing. This vehicle was purchased new in august 2003. I do not understand why gm was not compelled to issue a safety recall due to the risk of gas leaking. I would appreciate assistance to get gm to minimally provide defective parts replacement, due to the know manufacturing defect in the gas tank.

I started my vehicle and the instrument cluster did not work. No precheck lights except check engine light came on and none of the instruments on the panel would work. Tried shutting down the engine and restarting but to no avail.

Purchased a 2003 chevy trailblazer-ext lt in dec 2002 from the dealer, team chevrolet in pasadena. Since purchasing the vehicle, there's been several recalls, one in particular that keeps recurring are the brake lights keep burning, the dealer changed both units but it keeps burning out. I got tired of taking it to the dealer, so I purchased new bulbs and looked into replacing them myself. However when I unscrewed the bulb, I noticed the bulb just didn't burn normally (like a home lamp) it looked more of an electrical issue, the lining of where the bulb is screwed in looked like it had white residue and it smelled smoky. Also, don't know if its the shocks or suspension,makes odd noises. Dealer said its fine, but the noise is still there.shorly after my engine light turned on...the dealer could not figure what was wrong after a 2 to 3 week and costly expense and time...they switched out the gas tank...come to find out, that wasn't the problem, the engine light turned on again, they said one of the pistons needed replacing...$$$ that was a big expense and time consuming... Everytime I took it to them it, something was fixed, they charge, I pay, and the engine light would turn on, it got frustrating. Till, they finally got it right. Now my car sounds horrible (shocks/suspension noise got worse) when I go over city bumps or driving even small like hills, and mind you,which is driven by myself (female 124lbs) it shouldn't squeak or make noises, the brakes pedal makes a noise when I place my foot on it....yes it has 90k miles and it's an 8 year old car, but I kept up with the maintenances, I've taken it to the same dealer since it was purchased, only drive it to and from work....the car is in good condition, no hit/scratches/no tears.... I can't explain why.... Are there any other recalls, the dealer isn't aware of??? For instance they were not aware of the gas tank recall..which they were charging me over $1200 to repair, how can I trust they are doing their job?

I purchased a 2003 chevy trailblazer ext in june,2007. In jan of 2009 my problem first began. While driving normal speed, the service engine light sometimes comes on immediately followed by the "reduced engine power". When this happens, the car immediately loses power and the vehicles only goes around 10mph. You never know when it is going to happen. It can happen several times in a day or not at all. It is very dangerous when it happens because you can sometimes stop the traffic flow. The light will come off and the vehicle will return to normal speed if you stop the car and then restart it. It happens particularly when it is cold outside. In the morning it can happen 15-20 times before I get to work, and then in the afternoon only once or twice. I have taken it to several auto repair shops and no one seems to be able to fix it. They recommend one thing, I pay for it and then it happens again. I have had my clutch replaced and also the accelerator pedal system. I researched "chevy reduced engine power" on the internet and there are a great amount of pages of people experiencing this same problem. It appears to happen to chevy suvs, in particular the trailblazer. I don't understand how so many people can experience this same problem and there not be a recall. I have taken it to 2 chevy dealers and they don't even know what to do. I paid $18k for this vehicle in june, 2007 - I put $5k down and still owe about $10k. Chevy needs to recognize this problem and correct it. The vehicle is virtually undrivable and unsafe.

I am filing a complaint against the 2003 chevrolet trailblazer. I took my car into the mechanic because to see why the service engine light was on. He stated in that is was the evap system, meaning gases are leaking from my car. He stated in that its a common problem on these models because the hose attached to my gas tank causes the rim to crack and gas leaks through the crack everytime I fill up my car. I inquired having it fixed. In some many words he stated the only thing I could do is to replace the gas tank, but part (the hose) has not been modified from the original, so basically I will have the same problem. He showed me where the gas tank was moist from gas leaking. I am fortunate to have not been in an accident yet. However just to know that I have gas leaking from my car is enough to have me concerned. I would appreciate if someone can look into this problem. Thanks

The service engine light was coming on and we had diagnostic done and was told that it was the gas cap. We replaced several time. Everytime I drove or rode in my vehicle I smelled gas and I would get a horrible headache. My husband took my vehicle to get an emission test done we were told the fuel tank was cracked at the neck and leaking gas. We had it repaired nov 6, 2009 after we had been told of this. The shop that repaired my vehicle said they were shocked it had not caught on fire. There was evidence this had been going on for a while. Probably when we were told the gas cap was loose is when it started, and that had been over a year before.

My check engine light came on but the vehicle ran o.k. Took it to mechanic and was told that the oil pressure gauge was not working and he believed there was a recall on this. It wasn't a recall so we were told we would have to pay for the repairs ourselves and since we regularly change/check our oil I wasn't too worried. Now we have noticed the temperature gauge has shot all the way around and has stayed but when it is really cold outside it drops back to normal. The speedometer and the RPM gauge also sticks. Spent many days for a few years trying to solve problem with the radio and dvd player not working properly and switching stations on its own and after several replacements finally gave up because it was never corrected. This is a real concern as I do travel by myself and rely on the instrument panel and this seems to be a real problem with the trailblazer and should be recalled by chevorlet.

I filled my gas tank on my 2003 chevy trailblazer ext. And got a gas smell, shortly after the check engine light came on. There is a leak in the fill and fuel pump area I guess. I was referred to see if there were any recalls for this defect and came across this. The garage did a temp. Repair with silicon that only lasted 3 weeks. Now the same thing is happening. I would have to change the entire gas tank to fix this issue.
