Received a recall last October 2015 about strong gas small. Got appointment at Chevy dealer to fix problem in November. Dealer says I need a gas tank,but they can't get any from company. They have other recalls also with the same problem that are waiting. Now vehicle has become hard to start. Still waiting for dealer to fix. Why does Chevrolet send recalls if they have no intention of fixing the problem?? This is a dangerous situation with gas dripping, and the strong gas smell. It is a lawsuit waiting to happen if someone accidently drops a cigarette around the car.

My fiance had purchased a 2002 s10 Chevrolet Blazer in October of 2004 because he wanted me to have something that was safe and dependable to drive. Just recently my children were driving the Blazer when all of a sudden there wasn't any power from the motor. The Blazer stalled and my daughter who was driving tried to restart the engine when a passing motorist yelled out to her to get out of the car that it was on fire. The entire engine compartment had caught on fire from a faulty fuel line fitting. I was unaware of a recall to replace this and needless to say I am highly upset that I had come very close to losing two of my children. A car can be replaced but my children's lives cannot. This problem needs to be brought out into the public so others will know of its possible dangers. This time I was extremely lucky, but another consumer May not be. …
Hello, my vehicle is a 2002 Chevrolet Blazer, that I leased then bought. I am the only owner. On 10-13-06, I smelled gas when I walked up to the vehicle to get in. I took the Blazer into mike shaw (GM dealer) at 1080 s. Colorado blvd. Denver, colorado 80246 to be checked. Mike shaw found that one of the fuel lines coming out of the fuel pump was leaking gas. Mike shaw's service adviser (calvin scott) told me that they thought a rock hit the fuel line. The service technician (michael j. Tymitz) doing the work on the Blazer showed me the leak before any repairs were made. The complete fuel pump needed to be replaced at the cost was $890.51. I asked mike shaw if GM would pay for the repair and they told me no. The vehicle is out of the factory warrant time wise, but only has 31,900 miles on it. …
The fuel gauge sensor system becomes faulty after 74,000 miles. Mine started at approx. 90,000 miles. I have learned online this has happened to many 2002 Blazer owners & GM will not address the issue. Because of this the cars will not pass emissions due to a diagnostic trouble code & costs over $1,000 to repair on a 12 year old vehicle even thought it has nothing to do with the actual emission output. It is one thing to have parts break down with age and quite another to have the same part become faulty on a large scale. I cannot renew my plates due to the emission failure and cannot afford to fix a gage for a $1,000. GM needs to recall the vehicles and admit their fault using a cheap faulty part to save $$. I know this May not be a "safety" concern per say but GM advised me to make a complaint with NHTSA. My vehicle is my lively hood & I don't know what else to do.
After refueling our 2002 Chevrolet Blazer, there was a strong smell of gasoline. After taking it into the shop for repairs, the diagnosis was that the fuel tank and lines were rusting away and need to be replaced. Shop called us back and advised that parking break drums are falling apart. Every time we have an issue with this vehicle it has always been a major repair. Never a simple fix. With all the complaints on this vehicle I don't understand why the government doesn't force GM into a recall. This vehicle even qualified under the cash for clunkers program.
The fuel pump went out. It was replaced with a brand new pump, then 4 months later there is an obvious fuel line issue. My sons 2002 Blazer died while going down the street and there seems to be a leak in the fuel lines. After spending $331 for the fuel pump and now the Chevy dealer wants over $200 for the fuel lines for a problem that seems to be with the truck itself. I have read numerous complaints about the fuel lines in this year and make truck with no recalls I know of to resolve the problem.
