Battery died due to sitting for a long period of time. Even though car was started numerous times during the week. Tires lost air twice due to sitting and told not to drive the vehicle.
While driving upon acceleration increase of speed and slowing down there is a loud wining sound. When driving the vehicle for 15-20 minutes I can smell fuel inside the car. This is not when filling fuel it's while the car is driven for a length of time each day. The battery goes dead when sitting for one to two weeks. We have purchased 2 batteries in 1 year, had cables and connections cleaned and replaced. There has been messages coming up for "check engine" and the fan is noisy when the air or heat is turned up.
My wife was driving home from work yesterday evening at highway speed (65mph) when the car stalled and wrench icon came on. Could not accelerate but thankfully able to coast across two lanes on a busy highway at rush hour to get to shoulder! car was jerking as it came to a stop. Turned the engine off, waited a few minutes, turned engine back on and car was ok again. Unfortunately this wasn't the first time; there have been at least 5 other instances. First time was approx 9 months ago (before warranty was up). Brought the car to dealer, they plugged it into their computer and got no error codes so "no problem" detected. Now warranty is up I wonder how much this is gonna cost!! furthermore, the car battery went dead couple of weeks ago; that's only 3 and 1/2 years old. Seems odd.
