I have had my vehicle in for service 5 times for the same issue, it would not start. The first 3 times a sensor switch was replaced. The fourth time I was told my battery was the issue so I got a new battery. Today was the fifth time and the service dept indicated they could not find anything wrong but they went ahead and replaced the sensor switch again. I am not happy, I feel that I cannot depend on my vehicle. I am planning an out of town trip for thanksgiving and have resorted to renting a vehicle because I am paranoid about being stranded on the road with this issue. I paid alot of money for this vehicle and this just is not right. I am considering trading it in for a vehicle that starts the traditional way (with a key).

Waste gate actuator fails (replaced multiple times under warranty already) leaving the car with almost no power to accelerate or pass, unfortunately this usually appears when you try and cross a road/intersection and what should take 5 or 6 seconds to make a safe crossing takes much longer and it completely unexpected. This failure has now almost ended up in two accidents first when passing a vehicle and second crossing a 2 way stop and almost being T boned in what should have been an easy, safe crossing.

Car is not starting with push button start and depressing the brake. It takes several tries for it to finally start. It is intermittent, sometimes starts up right away, other times it doesn't.

3X the driver window button is inoperable. Would turn off car and then it would again work. The worst issue is this: Started up car this morning 7-9-12 (this is the 3rd occurrence) and the doors do not lock, then I put it in reverse and it goes about 2 feet and it applies the brakes. I noticed each time the gear console does not light up. The car actually does not go into gear. Each time I have turned off the ignition and restarted it and it works fine. It's going to the shop for the 30K check up and this will be brought up. The drivers window has been brought up and the dealer has said there was no problem. Wrong. There is when it doesn't work. I had one of these in 2001 and it too had electrical issues. My neighbor just sold their 05 Sonata due to electrical issues.
