Dishonest mileage claims: 2012 Hyundai Sonata."advertised: 26/35" - actual 24/25...not even close. Class action suit in ca but, inexplicably, only 'certain' models. I've not heard one Sonata owner 'happy' with their mileage. Its fraudulent and misleading at best. Hyundai is sending an engineer to look at the vehicle but if they're on Hyundai payroll what kind of result do you think I'll get?

The vehicle looses power while driving on the road and all the electronics shut down. I lost power steering and power brakes and could not stop the vehicle. The vehicle has an electrical problem that the service technicians can not see on the computer or figure out. First the service tech said it was a fuse not plugged in all the way then they say it was the battery.. I fear for my life in this car and will never drive it again. If I were in a cross walk I would have hit a pedestrian or I could have hit another vehicle. Luckily I was not on a high speed road or going through a toll booth or there would have been serious injuries. I cannot believe that the manufacturer feels I should drive this car. They told me it was ok before and I ended up having an accident. This car has an electronic defect. They do not put any value on lives.

2012 Hyundai Sonata. Consumer states concern with electronic ignition system and the lack of an engine kill switch. The consumer stated he had no way of shutting down the vehicle if the computer system accelerated or if he encountered a stuck gas pedal. The consumer wants to know, that he has a positive means of manually shutting down the vehicle in an emergency situation. The consumer would like a clear explanation of the push button engine star/stop switch. He would like to know is it a computer function or a manual electrical disconnect to the vehicles electronics. Also, if it is a computer function, will the dealer install a manual toggle switch under the dash that will kill all electrical power to the vehicle. The consumer stated the Hyundai sent him a letter, advising him to reference his owners manual. However, the manual did not address his primary concern. The manual only talked about how to operate the switch. Updated 11/13/12

After owning the car for one month (980 miles), my car lost power steering, air, and engine power while driving. A warning came on that said, "check charging system." It was towed to the dealer who said that they had never heard of the problem and that there was nothing wrong with the car. I refused to take the car back until a district parts and services manager can look at it. I called the Hyundai corporation who didn't seem too concerned. This is an extremely dangerous problem that Hyundai is not acknowledging.

Vehicle check engine lit and all dash lights lit upon starting the car. It would not let me shift it into any other gear. Car was towed to dealer for several days with them consulting with Hyundai. They replaced some control module to repair it. -------------------------- two weeks later, the same problem occurred. Idiot lights were on after starting the car, but I could not shift it out of park. Dealership swears its a different issue and they are consulting Hyundai yet again. My car has been in the dealership for over a week now and they can't tell me when I'll get it back.
