Gas gauge has not worked for at least 5 years every time I called the dealer they said no problem I think it is the fuel filter in the fuel tank and to fix that it will cost me about 1000.00 to fix. My son and a friend of mine had the same problem just didn't seem wright car only 5 yrs old and that goes wrong for five yrs I just fill my tank and go about 250 miles then fill up again. Please try to help me with this problem. Lights go out when it rains this is another problem

I was notified a while back about defective air bags in 2005 chevy trailblazers and I would be contacted on what procedures to take in order of correcting air bag. No one ever contacted me, giving me instructions on where to take my trailblazer re: airbag to have it corrected. Did I receive the notification in error? The date above (incident date) is not correct,..complaint could not be submitted without entering a date.

As of october 20,2014 I have yet to see the 1999 chevorlet s_10 ls or the 2005 chevorlet blazer s-t 4x4 my husband has tested both of these ignition switches and they are the same. He then called a gm dealership and they told him to not put anything heavy on the key ring. We are getting the same spill from gm as everyone else.why hasn't the s-10's and blazers been inspected, they have the same ignition switch from the 1999 s-10 to the 2005 blazer 4x4 and are very easy to knock in to accessory position. Because there has been no information put out about our ignition switches, we are highly concerned about the airbags as well. Why have these vehicles been overlooked not inspected and silenced? Noone has said the s10 or the blazers ignition switches are safe. There is absolutely no questions in our mind that the ignition switches are the same as all the recalled vehicles and faulty and possibly the air bags as well. Please,please look into this I have a daughter coming of driving age and we need to know our vehicles are safe for her to even step in.

I was returning from las vegas on a ruff paved desert hwy in my 2005 5 speed 2 door chevy blazer when I notice a slight smell of electrical smoke. I turned on the dome light and notice the turning signal switch arm bouncing a lot with some smoke coming out there at the column ! I slowed from 65 to 40 with my flashers on, problem solved . Got back on a smooth free way at 65 with no smoke. The switch arm got sloppier over time but still worked for about six months. Then one day I turn right with my signal on, windshield wipers came on by themselves, & the smoke was back (much stronger ) while driving slow! I then pulled into a auto parts parking lot, shut it off, & took out the keys! To my shock the wipers, & smoke kept going! I then opened the hood, unplugged the wiper motor, & again problem solved ! Then came a rainy day so I had to plug back in the wipers, things still all ok! But then I made a right turn with the turn signal on! The even stronger smoke was back plus my asthma attack (used my inhaler ) ! I thought about stopping in the strong rain but I turned on the A/C on full then got very mad ! I yanked on the plastic switch arm pulling it to the left, & it popped off in my hand! Problem solved except now my windshield spray, & wiper delay don't work! I still get some smoke on ruff roads! The whole turning signal witch part cost $599.95 at chevy plus $330.00 labor ! To rich for me! I took the small column dashboard panel off, put a kill switch on the wiper motor power wire just in case, & a light weight wood 6" cut off stained broom handle on the 4" metal switch arm ( drilled a 5\16 hole 4" deep)! I avoid bad roads, using turning signals, & I clean my windshield by hand often ! Problem solved for now! If the air bad goes off from this problem while driving I will probably have a heart attack, & die!

About a year ago I was driving to columbus, ohio and ran out of gas with the fuel gauge on full. This is a 2005 blazer. Was a year out of warranty and they wanted $800 dollars to take the fuel tank. Was told by the dealer this is a common problem, so where is the recall.

I was driving down the road took a right hand turn and my driverside back seat door flew open narrowly missing an on coming while I was on my way to pick up my 11 year old son. If my son was in the car and did not have his safety belt on he could have been thrown from the vehicle and even if he did he could have been seriously hurt or killed if the on coming car hit the open door. I registered a complaint with chevy and it was a real joke to them. What they said is because there is no recall they will do nothing and that I should take it to the dealer to have it fixed. I guess someone needs to be killed before they will take an action.
