While driving car, speed decelerated despite pressing on gas/accelerator pedal. Total ability to control speed on high way ended, as car crawled to a speed of under 5mph, nearly resulting in being hit by vehicles behind me. Immediately called independent mechanic who advised me to cut off ignition and restart the car. Highly dangerous to even attempt on a highway during rush hour traffic, nearly resulting in a multiple car crash. Reproduced several times until mechanic was able to diagnose and correct an issue unknown to me. There was no warning light indicator at all, no messages on car navigation/information panel.

I was driving down HWY 101 in Oregon State in the rain. I was accelerating because I had just turned onto the highway, I got up to about 60 mph whe the car started dinging as it does when you open the door with the keys still in the ignition. The VSA light, as well as the engine, oil, abs and battery lights all started flashing on the dash and the car turned off. The steering wheel locked up and I had to throw it in neutral, turning the key back and forth from the off position to the start position to get it to unlock right before I crashed into on coming traffick! There has been nothing wrong with the car other than routine maintenance an absolutely no signs anything is wrong with the car. It has 168436 miles on it and has been religiously maintained. There is a SERIOUS problem with this vehicle for something like this to happen. I've owned hundreds of cars and never experienced anything like this happening, ever!

My 2008 acura tl continues to display a "tighten fuel cap" warning light. I've replaced the fuel cap, but it continues to display this light. It is very annoying, and I've been reading other complaints online. My car is not the only one with this problem. I also had to replace my front motor mount and transmission.
