In 2018 we were having a fuel pressure issue and discovered that the icv had cracked around the gas tank. When I researched the issue I found there was a special coverage warranty for the issue and called the nearest Chevy dealership. They told me that the coverage had expired a month earlier and they wouldn't honor the coverage but if we wanted the car fixed it would be over$1000. We're not the first owner of the vehicle and im sure that's why I never received the notice of the special coverage. Considering this is an issue with the fuel tank and I have children in my car, I'm not understanding why this special coverage expired in the first place. People buy used cars all the time and if the dealership didn't catch it before selling the car it's unfair to put the expense on the new owner when it's a defect caused by the manufacturer's choice in unreliable parts.

Takata recall yes I was smelling fuel coming from the inside of the cab of my vehicle every morning well starting it up and it would remain so I looked into it and it was on a recall but they told me that the recall had expired and there's nothing they could do about it I don't think something as serious as this should have a limit on it because of the gas fumes constantly entering the vehicle I'd sometimes get dizzy and lightheaded causing me to pull over to leave the vehicle so I can get fresh air not mentioning always afraid of something sparking and possibly catching the truck on fire I have taken the truck to the dealer and they tell me like I said the recall has expired I am reaching out to you to help me get this corrected hope to hear from you very soon thank you for taking this time to read my complaint my name tracy O'brien live in palmdale California I cannot provide pictures because I do not know where it is coming from

Error code indicates a problem with the evap system. Won't pass state emission test. Cant diagnose further because of a gas leak at the gas tank filler hose connection to the gas tank. Notified by mechanic that they replaced tanks up to 150,000 miles but my truck is 185,000.

The area around the fuel tank filler neck, where it connects to the fuel tank, is leaking. This is a common issue with 2002 - 2003 Chevrolet Trailblazer ext's and GMC Envoy XL's. it is covered under General Motors special coverage program #14423 for 15 years or 150,000 miles. My Trailblazer now has 180,000 miles on it and I have been smelling gasoline fumes in the area of the filler neck for a long time, but I didn't know where it was coming from. I just found out about this program and checked the filler neck area and found the leak. Because the vehicle's mileage is outside the mileage limit of the program, GM will not cover the replacement of the fuel tank and filler assembly. I am stuck with a vehicle that may be hazardous to drive, but I have no choice.

Fuel leakage from fuel tank. Very noticeable after fueling up, and when it's warm outside. Fuel smell and visible fluid dripping from the fuel tank. Vehicle isn't safe to drive, and GM is unwilling to cover the cost for the poor quality of the design of the fuel tanks. It's a known problem that GM and it's dealerships try to pass the bill for repair onto the consumer.

Fuel tank inlet check valve fracture - Chevy Trailblazer (2003) I received the attached notice for special coverage in November 2015 for my Trailblazer's fuel tank inlet check valve that fractures and allows for fuel to seep out of the tank. Sounds pretty dangerous to me. I took my vehicle to the local Chevy dealership and sure enough, my vehicle was affected and the fuel tank needed to be replaced. The replacement fuel tank part was ordered by the dealership in November 2015 and the replacement part has still not come in, 6 months later. I've called the dealership, as well as GM/Chevy corporate at least 20 times over the past 6 months and the update I received today from the dealership was the part 'may come in September 2016 or it may not'. I can't drive the vehicle during this time due to this dangerous gas leak repair. This is wildly unfair. I was patient, but this is ridiculous - a replacement part should not take a year to receive. I'm guessing the part will not arrive in September either, as I was told in January 2016 that the part would arrive in February 2016 and obviously that didn't happen (today is April 15, 2016). Finally, the service I received from GM/Chevy corporate was appalling. Donna seymour - a senior advisor at GM/Chevy (1-866-790-5600 ext. 5911534) provided the worst service I've ever had, anywhere. She repeated would say she would call me back and fail to do so, and do absolutely nothing to try to resolve the situation. She was awful and GM/Chevy should be ashamed that they treat their customers in this manner.

While driving my vehicle in December 2015 I received a "service engine soon" display. I took the SUV to a service center who informed me my fuel tank was cracked & needed to be replaced. They ordered a new tank but have not been able to obtain the part. While researching the situation, I found record of an NHTSA investigation (action # PE07014) conducted in 2007 for the same problem, involving the same make, model & year as my vehicle in which GM was supposed to send letters to owners & repair the fuel tanks free of charge. I never received the notification and reached out to GM customer service to find out why, file a report and expressing my grave concerns regarding the safety issues of driving a vehicle in this condition. Over the course of approximately two weeks of communication, I was advised my VIN wasn't included in the action therefore they wouldn't have notified me, it was past the mileage warranty & they won't extend it, the part is on backorder and the soonest it might be available is may, they won't provide a temporary repair or loaner vehicle, there's nothing further they can do and they're closing the file on my complaint. They were however, willing to offer a potential discount on a new vehicle. I advised them I was not in a position to purchase a vehicle and that wasn't an appropriate solution to the problem.
