“The fuel gauge is not working properly. I ran out of fuel while traveling on the illinois highway 106. Luckily no other vehicle was near me at the time, as I lost all power controls on the vehicle at that time. The fuel gauge started fluctuating between full and empty and I had no idea how much fuel I had left, hoping to reach white hall, il to fill-up the gas tank.”

“I have had incidents several times over the years where I would hit a bump in the road and my car would completely shut off. I have also had several incidents where I was traveling down the expressway and my car turned off on me. I had to shift my car into neutral and restart it to continue going. I was fortunate not to have an accident.”

“The security sensor failed to read the key code and the vehicle will not start until the security sensor resets approximately 10-20 minutes. Sometimes this happens multiple times in one day, then it won't happen for a while. A week ago my car would not start for 2 days. We tried unhooking the battery and starting the car, but it still wouldn't start until a few hours later.”
