Front engine valve cover gasket leaked oil onto alternator causing it to become damaged, which led to poor transmission shifting and then complete loss of all electrical power.

Car started as usual and I was driving on a city street getting ready to get on the highway. All of a sudden the car would only go about 20 mph and reach 1000 RPM. It died shortly thereafter on the highway frontage road. All of the lights for ABS, brakes, check engine etc. Came on but the emergency flashers would not work so I had to keep pumping the brakes so nobody would run into the back end of my car. It would not restart so I had to have it towed to the dealer. Dealer stated valve cover gasket had leaked oil onto the alternator and ruined it. That in turn ruined the battery. Car was repaired for $1400 including the tow and a rental car. After looking at Hyundai recalls, I noticed the one for the 2009 vera cruz (NHTSA# 14V415000) in which 61,122 units were recalled for this same problem. In researching the affected valve cover gasket, I found the same one was used on my 3.3L engine that was listed as defective on the 3.8L vera cruz engine. If that part was defective on that vehicle, why was the scope of this recall not extended to cover all possible vehicles that could be affected? I would like the cost of repairs refunded to me since Hyundai obviously knew this part was defective but didn't issue a recall to cover all affected vehicles.

On 10/08/2009 my 209 Hyundai Sonata went into an unintended acceleration. As soon as I put the car into drive it began to accelerate. The brakes did not work and I was able to shift into neutral. I was on a narrow dirt road with little limited options as to where to steer the vehicle. I missed a boulder, garage, and tree before hitting the side of a house. The ambulance was called and I was transported to the local emergency room. I had a concussion, fractured knee along with a number of bruises and abrasions. The emts told me how lucky if was since the air bags did not deploy.. an internet search, including your website, notes these problems going back several years. Toyota had the same problem and did a recall. My injuries will exceed the limit of my insurance and I will have to purchase a car. I know how lucky I was to walk away. I am sure others had more serious injuries and higher expenses. What does it take to force Hyundai to do the right thing?

Bought car new, at 30,000 mile starter replaced [ could not turn key in ignition]. that was covered by warranty. At 63,000 miles igntion went [ again unable to turn key to start car ] and I was stranded with vehicle.--this time approx $650 I for repairs. I have heard /read there is a history fo this kind of problem. Hyundai did give me a $200.credit toward next repair. With my age and being widowed I really would like to feel confident that this car is going to be safe for me. I just don't think with the amount of mileage that these problems should have existed. Are they using inferior parts ??

ESC light comes on intermittently common problem with Hyundai. Previous recalls and current recall on some models. I am filing a complaints with national safety so that a recall can be extended to more vehicles. Hyundai is unwilling to fix these issues without a recall. Want people to pay out of pocket for something that is a manufacturing defect.

Hyundai Sonata 2009 red warning light for passenger seal belt stays lit even if no ones setting there or only a purse, or no one setting ther. So I have to put seal belt into lock even when no one setting there. So I have to fasten seat belt all the time. When driving car all the time have to keep it fastened. Also window electric switch on driver side most times doesn't function properly. Then deal sold me it a few months ago. I opened door cover to see if it was a switch problem & there was 2/12 inches of dried dirt in bottom of door panel. Dealer large one in san antonio, tx, at used lot say it is normal. I seem to think it might have been flooded in water he say no way it normal. Sure jokes on me now purchased as is dummy me, in limbo in tx. Car paint is starting to chip as well with deep open scratches weird every wash seems to make it worse looking.

My driver side door lock button does not work. As the driver, I am unable to unlock or lock doors using this button. Instead I either have to get out of my seat to unlock the other doors. This is a personal safety hazard because I have no control over my door locks and forced to get out of my seat or vehicle to either lock or unlock doors when the car is in park.

Sonata 4-cyl

  • 163,925 miles
After vehicle engine was running the starter motor engaged while the engine was running. The vehicle was idle parked the shift position lever was in the park position.the starter motor will engage on it's own in the park position and in the neutral position. The stater motor will also engage and crank the the vehicle engine in the drive or reverse positions this symptom developed later. I had a certified mechanic look at the vehicle and he said the ignition switch was defective and will have to be replaced. I check for recall information online and found no reference to the problem.

The car was in the driveway warming up and caught fire it burned up the starter and starter assembly, the battery wire harness and the manifold. All of this has to be replaced before we can assess any other damages or run a diagnostic.
