While driving car just stops. It has done this several times but starts back up once you put in park. However this time it stop while driving and did not start back up. The first it happen I took it to the shop and they said they could not find anything wrong. Even though the "check engine" light was on. Now it will not start at all.

Several issues with the vehicle, airbag has had several problems, never deployed when in accident, first issue was covered under warranty, said they had to rewire it, a few months later light come on again. This time they tell me the circuit motherboard has crashed, completely disabling the airbag. Second incident was with alternator, light continued coming on, dealership said nothing was wrong with car. Car eventually broke down in traffic, alternator had went out completely and it was only a few days after the warranty expired. I was forced to come out the pocket, now there are issues with the engine. The shaft position sensor has failed and my car broke down on the interstate. There have been several issues with my car, and I use it for transportation from school and work locally.

While driving, under many different conditions, my Hyundai Sonata stalls. It has happened over a dozen times. After pulling over to the side of the road, I let the car sit for a while and it starts right back up again. Occasionally I have to have it towed. It does not seem to occur while the car has cruise control on, even without it being engaged, just powered on.

This car presents with a loud clicking sound which is very distressing.once it begins it lasts for several minutes sounding for long periods and at times short bursts. I have taken it to the dealer twice and the problem has been neither identified or rectified. Until last night I have been alone in the car when this sound presents. Last night when it presented there were passengers present. Although the car did not falter it was none the less very distressing for my passengers and me. We turned off our cell phones and shut off the radio to no avail. With no resolution or information as to what is the cause I am left wondering if I am driving towards some malfunction. This clicking sound always presents while driving on freeways at freeway speed.

Consumer called complaining about having problems with idle speed and vehicle will stall. Also stated that while driving the vehicle the vehicle will start loosing power on highway speed. Dealer was contacted and stated that this is a intermediate problem and unless Hyundai sends out a letter or something that states the problem they can't do nothing about it.
