When I wash my car I like to wipe down the engine and the inner part of the front hood. About a week ago I went to wash my car open the hood only to discover a white substance (almost like white battery corrosion) running all down my fire wall cover. I made an appointment with the service department told them not to do anything to the car until they can explain to me how it happen and how are they going to fix it. About 20 minutes later the service manager calls me over and explains to me that the white substance on my firewall was when the detail people from where I purchase my car left it there. I explain to him that would be impossible since I always look at my hood and this was the first time I saw it. The service manager then turns to the two decals on the top of the hood and stated they may be water seeking in but because he did not find the firewall wet he just wiped off the white substance and told me there is nothing he can do it's just the designee of the decals. I'm not even sure it is the two decals; but one thing for sure something is allowing water to seek into my firewall and Hyundai is not taking care of their customers NHTSA please help.

This vehicle had a serious safety issue occur around 5:00 am on July 10th; as I was driving out of my driveway (car in drive and in motion) all power failed. No lights, acceleration, power steering or brakes, etc. Which was a serious hazard especially given the darkness at that time of day. This safety issue followed multiple occasions where all the power failed when trying to enter the vehicle using the provided key fobs. These situations could also have been dangerous as on one occasion this happened while my car was in an urban parking garage in the evening. It took approximately 45 minutes- 1 hour before the power restored and I could start the vehicle. I brought it to the dealership on July 5th to remedy the power issue and the technician could find no issue - they switched out the car battery as a precaution in the event there was a hairline crack causing the intermittent power failures. As of August 27th, the vehicle was still not repaired from the July 10th incident. Dealership notified me it was replacing the entire fuse box and engine wiring harness as the diagnosed cause of the failure.

It started as some small shocks from door and steering wheel. The vehicle now shocks you from just about anywhere you stand. I did bring it to the dealer and after having for over 3 days only a oil change had been done. I asked to pick up for a appt. I had on Sunday and all three pages of what was to be looked at stated work not done.I told service advisor I needed to get car fixed before I drove across country, I asked to bring it back and he said I thought you were leaving which I am but very concerned about driving any length because it gets painful if I have to turn on lights.

While traveling down the road at approximately 50 mph the crank pulley fell off the motor. This prevents the alternator, water pump and ac compressor from functioning as they are belt driven. With the alternator not functioning the batter will be drained to the point of dead (depending on what accessories are on) and with the water pump not functioning the car will almost immediately overheat leaving the vehicle stranded.
