My husband and I just dropped our two kids off at my mother-in-laws house and were on our way back home when I started to smell gas. I told my husband and he stated to pull the car over and he would check it out. He popped the hood and flames shot out from under the hood. The first thing that I thought was my husband was on fire. I jumped out of the car and found my husband on the other side of the car looking for the kids in the backseat and he was screaming get out of the car. I jumped out of the car and we ran. We looked back and all I saw was a big ball of fire. When the fired department put out the flames all that was left of my car was a burnt frame, the 2 back tires and the spoiler. My husband and I are really upset by this situation. What if our five months old and nine year old was in the car at the time? What if my husband was burnt severely by the fire? …
On July 29, 2008 I went to get into my 2007 Toyota Corolla and smelled gas. I crouched down to look under the car and noticed a gas leak coming from the gas line under the gas tank. I got up to walk into the garage and when I closed the car door, the car exploded into flames. The explosion pushed me into the garage and I was able to get the garage door closed. The car was a total loss. After looking at other 2007 Toyota Corolla's it seems there is a defect in the fuel line under the car. The fuel line is the same consistency as a radiator hose and is the lowest hanging structure under the car, with an area that is not protected and could very well get punctured by normal road conditions causing a gas leak in the fuel line which is very dangerous, obviously, since ours exploded into flames and burned so hot that it melted the top of the engine. …
I had just started the car up and was pulling out of a parking lot.the car excelerated on its own .I could not control the speed and it did not respond to my trying to break. I had to put the car in neutral to regain control.I missed htiting another vehicle and people walking in the parking lot. I had the car repaired technician suggested throttle body replacement. . To correct the problem the throttle body was replaced with gasket and performed relearn. Total cost $619.50 jan .2 2019
Started car this morning and the check engine light came on. Took to parts store and hooked it up to the computer and found codes (p2401, p043e, p043f, p2402, p2419) everything I have researched comes back to EVAP canister failure, and possible wiring failure. More research shows these issues causing people getting stranded and others with no problem other then light, and others with a strong gas smell. If this causes a gas smell, then a potential fire hazard is formed.
The check engine light came on. Took it to a mechanic & he said the gas cap wasn't on tight enough. That worked for a couple months before the light came on again. So the next step we replaced the gas cap & a week later it came back on. The mechanic now says it's the fuel tank needs replaced.
I have been smelling strong gas smell with my 2007 Corolla car. The RPM reves high. In just a 20 mile trip I can visabily see the gas go down on the gas odomitor. No warning lights are on but there is something defineatly wrong with my 2007 ce Corolla.
1- an undetectable event caused a small hole in the fuel line of a Toyota Corolla. The air in the garage where the car was parked overnight was permeated with the odor of gasoline, and introduced the real possibility of an explosion. 2- the failure is a weakness in the strength and durability of the fuel line of Toyota corollas. The fuel line had a small puncture and filled the confined area with gasoline vapor. 3 - Toyota required a replacement of the fuel line and gas tank, claiming that a rodent chewed through the fuel line. The new gas tank has the same design flaws and weaknesses as the old gas tank and can easily be punctured. Fuel line problems have happened in more than one Toyota Corolla that the company has owned; one of which burst into flames. …

The vehicle check engine light comes on. The codes identify it as p0456. When we took it to the dealer, they tried to tell us that an animal had made a small pinhole in the gas return line. They wanted to charge 600.00 to replace the tank or they could temporarily fix it until we could get that done. The temporary fix after a few months opened and we got the alert again. Taking it back they said the temp fix was okay and they couldn't find anything wrong. Upon return home, I looked and found the temp fix was electrical tape rapped around the line. There was evidence of leakage and you could smell the gas. I removed the tape and it appears this is a very thin hose. It is in a position over the tank where wind could blow it up and hit the underside of the car. That is not smooth and could have caused the puncture. Taking to another dealer, they wanted to say the same thing. …
I stopped at a gas station to fill my gas tank and while this was being done I heard a loud bang similar to a gunshot. When I started my car there was a loud rattling sound. I stopped the car and got out to look underneath but couldn't see anything hanging. Since I was near home I started the car and drove slowly home. I took it to the dealer the next day and they repaired the gas tank strap passenger side. I told them I considered this to be a design defection and a safety issue. They stated there has been no recall despite the fact that they had seen quite a few of the same problems. I had to pay for the repair. Toyota corp has refused to reimburse me for the repair because my car is out of warranty. I have had many cars and have never had this problem before. …
