I had just put $35 in gassed the car still said I needed gas and that I had zero miles left of gas I made a trip that was about 45 miles in distance. My car was then parked and turned off for about 3 to 4 hours then it had trouble starting at first but turned on and I proceeded onto the freeway which was across the street from the parking lot I parked inside of. It was about 9:00 pm and thankfully there was not a lot of cars out. The entrance of this freeway consist of one medium sized steep hill which remains traveling upward onto a mountain when my car suddenly shut off my 3 year old daughter and I were in the car and thankfully we were on the last lane due to the fact that we were barely entering the freeway. I parked on the right side skirt I had just replaced that battery earlier that week (no more than 5 day before). I had a small gas can in my trunk and had someone go to the gas station and bring me the gallon of gas which I emptied into my car and it turned on. At times the car does smell like gasoline especially if I just put gas. It doesn't matter how much gas I fill up my tank with it will indicate I have 0 miles of gas in the screen and the fuel gauge will not go below the middle indicator and will never show above 3/4 full. My tpmsa is always indicating a problem when the I have a mechanic see it and he assured me it's in good condition

Just purchased the car april 13, 2020. Strong gasoline smell emitting from front end of vehicle and in cabin. Seems to be coming from the driver side of car. Does not happen all the time. Does not matter if the gas tank is full, half, or empty. Can't find any leaks under the hood, but still has a very strong smell of gasoline.

My car started to smell like gas inside, and it was a very strong odor. I went to an auozone to get a diagnostic, in the system it had said it was a very small gas leak and that it would have been okay to drive. I kept driving and it still smelled like gasoline and stronger each time. Therefore, I took it to the mechanic the next day driving it, and under the back seats was filled with gasoline. The mechanic still cant find the leak. However, if I would have kept driving it, the car could have exploded on me.

Excessive gas fumes from car. Dealer and other service center looked for problem several times. After car was unfit to drive - smelled so bad from gasoline fumes - a service garage removed the fuel tank. The fuel was seeping through molded in plastic connection fittings on top of the tank at their molded interface to the tank - the tank is a poly type tank. The tank was replaced. This is clearly a design defect. Had the fumes been near an ignition source a possible fire or worse could have resulted. It is my opinion that the dissimilar materials used for the tank and fittings lost their seal over time. Audi of america has shown no interest in dealing with this. Since there were 4 fuel tanks available on a friday and on the following monday, there were none, so I had to wait up to 2 additional weeks to get a tank - I suspect they are keenly aware of this defect. This car has been garage kept, I am original owner, and it has no accidents. I have the original failed fuel tank at this time. Date of repair 6/29/09 to 7/21/09.

I purchased certified pre owned car from dealership-audi a4 3.0 quattro, 2005. 2 days later I could not pass required state inspection due to "check engine" issue-misfire on a 6th cylinder. I brought the car back to dealership a few days later to correct the problem. The problem was corrected temporarily and car passed the inspection-'check engine' light was reset by dealership. A few months later "check engine" issue came back after scheduled maintenance (at 50,000 miles) was done by authorized dealership. Problem was temporarily corrected 2nd time. In december 2008 after 3rd time "check engine" issue, dealership proposed to replace whole engine in order to resolve this issue, which was done. On february 11, 2009 driving back home from work I've noticed an exhaust gas smell inside the car, car was shaking and "check engine " light was "on"/not steady. I contacted audi customer service advocates to report the problem and start the case. I brought the car back to dealership for repair 4th time. They performed necessary steps to correct the problem but failed (2 sensors were replaced according to them and "check engine" light still "on"). I was informed that dealership did not replace the whole engine back in december 2008 - they only replaced lower part of the engine knowing that there was a problem with misfire on 6th cylinder (upper part of the engine). After 3 weeks of waiting and constant repairs I am not sure that this problem has been corrected permanently. Facts: car was purchased at 49,000 miles on april 29, 2008. My car has been at dealership for 75-80 days out of 10 months since I purchased it. Total mileage as of february 28, 2009 is 52,450.

This incident happened in indianapolis indiana around 11:40am the temperature outside was two degrees fahrenheit. I was driving my 98 audi a4 2.8 quattro north on a two lane city street with a speed limit of 35mph. I had been driving for twenty minutes and smelled a very powerful gas smell since I started driving. My foot was on the gas and all of the sudden the acceleration of my car increased to 45mph. I tried breaking to slow the car down and the break pedal resisted my effort. I was able to slow to 40mph but no lower. When I took my foot off the break the car accelerated greatly. Despite breaking, the speed kept increasing. I felt I had no control over my car. I was traveling for over a mile at speeds reaching 60mph on a 35mph speed limit. I approached a red light, luckily it turned green the minute I went under it. Had it not, I would have run the red light at a busy intersection. My car reached speeds too dangerous for the road I was on. I moved into the center lane into oncoming traffic, fearing I would hit the traffic in front of me. While driving over a mile unable to control my speed I was looking for somewhere to pull off and get out of traffic. When I did pull into the center lane I was able to turn into a parking lot at 50mph. I pushed the breaks with all my might; it did not stop the car, so I put it in park and turned the ignition off. Had I not found that parking lot, I would've run into a snow embankment or hit a building. There was no chance my car was stopping and I had no control of the speed or breaking. I am very lucky that parking lot was empty. I realize that my speeds were very dangerous on this road. Speeds of this nature could've resulted in damaged property and injuries or death to myself and/or others. This was a very frightening and upsetting experience that could've resulted in major damages, injuries, or even death. My safety was compromised.
