The contact owns a 2000 Hyundai Sonata. While driving approximately 45 mph, the engine began to rev excessively high and the vehicle lunged forward unexpectedly. When the accelerator pedal was depressed, the vehicle hesitated and vibrated. In addition, the automatic transmission shifted violently into gear. There was no power response during acceleration, which resulted in the engine stalling intermittently. The warning indicator also illuminated on the instrument panel intermittently. The vehicle was taken to an authorized dealer for inspection, but they were unable to duplicate the failures. The mass damper was replaced. The vehicle was taken to an authorized dealer on six separate occasions for identical failures. The repairs consisted of a complete tune up, replacement of the "output" speed sensor, and the battery was replaced twice; however, the failures continued. The extended warranty on the vehicle expired at 60,000 miles. The vehicle has not been repaired. The failure mileage was 13,559 and current mileage was 82,505.

The contact owns a 2000 Hyundai Sonata. While driving 25 mph, the front passenger side tire assembly was falling off the vehicle due to a rusted engine cradle on the front passenger side. The vehicle was taken to a service station and they replaced the passenger side driveshaft assembly. After the repair was made, the contact still heard noises. The vehicle was returned to the shop and, upon further inspection, the engine cradle wheel hub assembly was found to be out of place due to rust. The entire wheel rotated while the driver side remained stationary. The failure caused the engine cradle to rust. There is a current investigation (PE08029) for this failure. The current and failure mileages were 129,358.

The crankshaft position sensor is faulty. I don't understand how Hyundai can have a recall for this item in their Kia optimas and Santa Fe 2.5L V-6 engines, but not in the 2.5L V-6 Sonatas. The least of the problems is difficulty starting, which seems to be the culmination of the problem. The beginning of the problem is the loss of power and stalling, incredibly dangerous while on the highway traveling at 60 mph and without warning the car loses power. Last year I spent over $500 for a tune up and spark plug wires. The check engine just came on today after having trouble getting started and had it diagnosed as a P0335 crankshaft position sensor a circuit malfunction. I called several dealerships and the repair is in excess of $400 for labor plus parts.

I was traveling down the highway when without warning my engine simply shut off, and the power assist to the brakes and steering was stopped. I tried moving from the center lane over to the shoulder and was almost rear-ended by a vehicle in the right lane. I was able to pull the car off on the right shoulder and stop. The vehicle would not restart and I had to have it towed to the nearest dealer in the area, pugi Hyundai in downers grove, il. They took the vehicle in for service and later in the morning informed me that the crankshaft position sensor had failed. The cost of repair will be a minimum of $600, and possibly more, depending if they determine the engine needs additional repair parts.
