2001 Hyundai Sonata Owner Comments

problem #7

May 292010


  • 130,000 miles


I came to a complete stop after driving only 10mph, my engine cradle dropped down there for smashing through my front axel, and turning in both of my front wheels. Not realizing what happened I continued to drive to a repair shop. Both tires popped. I called a tow truck and paid an outrageous amount to get a tow to a repair shop. I was without a car for 2 weeks while they replied my vehicle which cost me almost $1,300. My insure company would not total out my vehicle because they said it was due to salt corrosion and rust (ware and tear). Did I mention I was on vacation when this happened? $$$. now my transmission is trouble shooting somehow (151,000 miles). It's having trouble switching gears and it hits pretty hard when it finally does. I have to turn the car off and turn it back on, sometimes this helps sometimes it does. My RPM shot up to 4 or 5 which burns gas like crazy. The rust on the rear wheel wells and bottom is unfixible. Steering wheel shakes really bad at speeds 60+. my rear struts are rusted and need replaced.

The contact owns a 2001 Hyundai Sonata. The contact stated that the cam position position sensor failed. She took the vehicle to the dealer and they stated that they did not have the part to repair the failure. The contact would have to purchase the entire engine harness. The failure and current mileages were 87,000. Updated 11-25-08 updated 11/26/08.

Sonata 4-cyl

  • Automatic transmission
  • 80,000 miles
I bought this car brand new. Since its 80,000 miles mark the dealership has been having trouble fixing the camshaft position sensor. This defect causes my car to stall in ongoing traffic and caused it to come to a roll and stop. My car has been in the dealership for 2 whole months where it has been test driven and now has 100,000 miles on it. The air bag light stays on even after it has been turned off.

Sonata 6-cyl

  • Automatic transmission
  • 29,100 miles
The consumer was going about 25 mph and the check engine light came on and vehicle just died. The vehicle jerked to a stop, then later drove normally. Later, the check engine light went off, and it began to drive normally. The consumer took the vehicle to the dealer, who was not able to duplicate the problem. However, the service manager said there was no problem, but the consumer $135 for changing the transmission fluid. After getting the vehicle back on 8/24/04, the vehicle suddenly made a loud grinding metal sound, the dealership claimed it was the trans axle. The consumer stated that they were guessing just to get her out of the dealership.

Sonata 6-cyl

  • Automatic transmission
  • 28,000 miles
While driving, thr vehicle jerked to a stop. It was discovered that speed sensor was defective. The vehicle was taken to the dealer, but the manufacture will not accept responsibility. The brakes had worn away, one brake pad was missing, there was a loud grinding sound in the rear of the vehicle and the vehicle refused to shift when turning corners. The service dealer found it nessasary to replace the rear oxygen sensor and found that the output speed sensor was faulty.

problem #1

Feb 232003

Sonata 4-cyl

  • miles
The vehicle stalled, which caused the vehicle to abruptly pull. There was a vibration when the vehicle was stopped at high speeds(due to warped rotors), a tap noise was coming from the timing belt, and the vehicle would die at the speed of 60 mph. The timing belt, the broken counter balance, and the missing timing belt teeth were replaced.
