Lately, and intermittently, when the gas tank is 1/2 full or less and a sharp turn is made, the gas gauge goes to E, the low gas light comes on and the car will not go more than 20 mph as if it is losing power. It's most scary when it occurs making a turn onto freeway entrance ramp and I am trying to get power to enter moving traffic. Typically, I have to pull over, turn the car off and restart to get the car to run normal.

My car has been swallowing gas. It uses 1 gallon per 5 or 6 miles, it doesn┐┐T accelerate, and it keeps turning off when I slow down, and I have to re-start it. It has become very unsafe for me and all the drivers around me. I took to the dealer. They said they checked it, and they replaced only one little gas cap. They said that it will take care of the problem. It didn't. I still have the same problem of high fuel burning. I took it back to the dealer. They checked again. They said the fuel tank needs to be replaced and they want to charge me $1027 to replace the fuel tank. Several mechanics told me that there was recall on fuel system on my type of vehicles. I shared the recall information with the dealer, but they said that there is not recall. I have checked recalls on line, and have checked more. Others drivers have had similar problem. The complaints can be found in www.mycarstats.com/reports/Chevrolet/Trailblazer/2002/complaints.aspx please assist in anyway you can. My contact information is 480-232-9116, and my name is rosa hacopians. Thank you!

I was driving home from work and started hearing the trucks undercarriage start to rattle and grind on the bumps of the road. I had a sudden loss of power on engine and it wouldnt respond to my pressing on the gas. I believed that I had gas in the truck because the gauge read half full and apparently I was out of gas. So I proceeded to pull into a gas station and as soon as we filled up, the truck would not start! I saw that my check engine light was on and had to ask for a jumpstart to get it started again. At another time and date again the truck went dead, I asked for a jumpstart and the vehicle would not respond. I now had to buy a new battery because the car damaged the original battery and now with the new battery installed my car starts but will not stay on without me pressing on the gas while in park gear. I believe something may be defective with the electrical gauges, fuel delivery system, and suspension.

I feel that even if you have had a recall issue once and the situation continues to happen then it needs to be fixed until the problem is solved I have contact GM several time and nothing has been done to ratify my problem with the windshield wipers and the 4 wheel drive and several other recall issues this is sad I say we need a class action law suit I am not one to take legal action but for people that have this kind of money and to not fix their problem that they put out on the roads for us to drive safely is shameful.

When I drive my Chevrolet Trailblazer, the gas gauge is all over. I can have a full tank one minute, and half a mile down the road have 3/4 of a tank. Also it does the same thing when it has a quarter of a tank, it will say it has 1/4 of a tank, and a mile down the road it just drops and the low fuel light comes on. Also I can park the vehicle with about 3/8 of a tank, and start it later, and it says empty, and the low fuel light is on. We also have a 2004 GMC Envoy that does the same thing. This has been an issue for both vehicles the entire time we have owned them. Both were bought in 2010. This occurs every tank of gas, and the actions are not always the exact same, so it is hard to tell if we actually need gas or not, sometimes they are actually almost out other times the have approximately 1/4 of a tank left. We have not done anything to correct the issue because we do not know what is causing it.

The contact owns a 2002 Chevrolet Trailblazer. While driving approximately 40 mph, there was an overpowering gasoline odor in the vehicle. She stated that the service engine warning light was illuminated on the dashboard and the failure persisted for several months before the vehicle was taken to the dealer. The dealer advised that the fuel tank was leaking where the filler neck met the tank body. She was advised that the fuel tank assembly would need replacing. The vehicle was not repaired. The failure mileage was 162,121 and the current mileage was 162,563.

Parked Trailblazer in garage last night and this morning smelled gas in garage. Underneath the truck was a puddle of gasoline that had leaked out. It seams to be leaking from below the rear seat and middle of the vehicle. I am reading about many similar problems and concerns that other owners have about this potentially dangerous situation. I would like to know if there are recalls or other means of getting some help so I can repair the problem asap. Hopefully not at my expense. Thank you for the opportunity.

Wife put fuel in the vehicle because it was down to a 1/4 tank and it is now the winter months, we dont like to be below half a tank. She drove it home and later that nite I got into the vehicle and noticed the gauge read empty and the light was on. I went to put fuel in it and at 5 dollars the tank for fuel. The gas gauge show empty upon even after filling the tank. The fuel level in the tank falls to a sufficient level to cause the gauge to display erratic and false readings. Nothing has been done to correct the failure which continues to be a constant problem. Fuel level now must be estimated through the use of the trip odometer the gauge reads full when you first start the vehicle and sometimes stays at full or reads empty with the light on. Called local garage they said sounds like a bad fuel level sensor common problem with Chevy Trailblazers from 02-09.

Trailblazer 6-cyl

  • 144,000 miles
I have been smelling a gasoline odor on the side of my SUV where the fuel door/fuel tank is located. Research on the internet yielded many Trailblazer owners reporting fuel tank/sending unit/pump corrosion resulting in a fuel leak. A family member of mine just had this exact problem repaired on a 2003 Chevrolet Trailblazer. I believe this same issue is starting with my 2002 Trailblazer. I replaced the gas cap to eliminate the possibility of the gas odor coming from the tank fill area, but the odor persisted. The odor resembles an actual gasoline spill and/or leak and not just gasoline vapor odor, ie: Filling the tank. Like I stated before, internet research yields many Trailblazer owners reporting this issue and having to pay for costly repairs. Any issue regarding the fuel system/gasoline, in my opinion, should be an immediate safety concern. I have not received any information from GM in regards to a recall bulletin. I am going to conduct more investigation, but in the meantime the smell of a gasoline leak is unmistakable. I hope this information is helpful and I hope that a recourse regarding this issue and its repairs can be formulated. In the meantime I feel that a major safety issue is present and needs fast and efficient attention. Thank you. The consumer stated the fuel pump was severely corroded on the top including two fuel lines that exit the top of the fuel pump. There was a fuel leak resulting from corrosion. The consumer paid for the repairs at his expense. Updated 12/16/10

I have a 2002 Chevy Trailblazer that has had a host of problems to date. Now I am experiencing two more. Twice in the past few months I have been driving down the road with a 1/4 of a tank of gas or better when suddenly the car stalls, the gas gauge goes to empty. If I sit for a moment and then restart the car, the gas gauge goes back to 1/4 full or better. It is very frightening when the car just suddenly stalls out without warning. The other problem is the ABS system is now coming on when it should not. In the past two weeks I have had trouble bringing the car to a stop. The ABS comes on and disengages the brakes and the car skids ahead instead of stopping immediately. We had the same thing happen on our 2000 Chevy Silverado truck. It was fixed under recall, then started happening again after a couple of years. When we called Chevy, they said they only fix under recall once. We were able to disengage the ABS. I have my service station looking now to see if we can disengage the ABS on the Trailblazer too. These Chevy are a real hazard!

There is a very bad gas smell coming from my 2002 Trailblazer. From what I'm led to believe it's the gas tank and the fuel pump. I have not had it replaced as of yet but I'm sure I going to have to at my expense. I think it should have been a recall if it is an error on their behave. With all the complaints I'm finding on the internet I think it was something they may have missed.

Came home after refueling my 2002 Chevy Trailblazer ltz w/151000mi, noticed strong smell of gasoline. Never noticed before - thought I just spilled some. Smell persisted, looked under hood, under car, noticed fuel dripping down from fuel tank. Called GM cust svc 866-790-5600 was advised there is special coverage for warranty replacement of plastic tank to remedy corrosion. Supervisor confirmed my VIN is in range but would not honor warranty - they only cover to 10yr-120K mi. Vehicle has never been in an accident, so crack in tank must be a manufacturing defect - plastic tank should last the life of the vehicle. GM refuses to accept responsibility for defective tank.
