2000 Hyundai Sonata: hesitation when accelerating

Filed Jul 16, 2009 · Acceleration, Engine · 13,559 miles · NC

Tl*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.

While driving at about 35 MPH the engine stalled then restarted while in motion. Then the vehicle started hesitating form a stand still and felt like it did not want to accelerate. I contacted the dealer and the following day they found a faulty cam sensor which they replaced. Two days later the vehicle started hesitating from a standstill and then started stalling when at a stop I.e.red lights. I contacted the dealer on 6/28 and they checked the car the next day. They agreed with the hesitation problem and said the history code for the cam sensor failure had not been cleared. Seemed a little fishy to me. I asked if this would remedy the problem. The response was if it didn't give them another call. I said what if I am on the highway and it fails. The dealer said " call the road service number and have the car towed to them" that seemed to me to be a very short sighted view of a very dangerous condition. I cannot call if I am killed because the car stalls on the highway or it is in the middle of the night and I don't have a cell phone?. They designed, manufactured and warranted t the car. Seems to me it should be emcumbent on them to backup their warranty and not leave it to the risk of the consumer's life and limb until the car finally fails at a very inopportune moment. As an observation, this problem fits the description of the federal safety agency campaign id # 00v259000 which I complied with.

I had my bearings replaced, my rear hub bearings. Now it is making to same noise and they now say it is not the bearings-they do not know what it is! My car idle sounds like is going to stall all the time when I am stopped. The car pulls around 5,20 and 50 MPH like it just cannot get gas or the transmission is bad. I brought it in 2xs. They say they do not know what it is and cannot get anything on the diag machines. Now I am passed 60,000 miles. After having my car for 2 days (giving me no lender or rental) they found a problem at the last minute. Oil leaked from the valves into the spark plug wires into the coil pack and that is the car pulling problem. They say I have to pay $600 to fix it. This was on june 6,2003. I brought the car in for the idle which was not fixed and brought it in for this engine hesitation 2xs. Both times they did not and couldnot fix these problems. I have the receipts that they could not fix nor repeat these problems, but they are noted. I should not have to pay for these repairs!!!! This is not daily upkeep!! This must be defect!! I have a real problem with this car! I need to be contacted on this matter for hyundai to pay for these repairs! I am having a difficult time on this matter. These parts need to be replaced now and I cannot and shouldn't have to pay for these parts or labor! I also have had my front driver window regulator fixed 4 times, my front passenger side regulator fixed once, my rear regulator fixed once. I had to buy a new battery for my car and a new headlight in the first year(hyundai said I had to submit paperwork to see if they would vote to repay me for my cost of the battery). I had my air bag light going off(which now I never trust for it to go off when needed or even go off when not ). My paint is chipping everywhere! My front passenger window leaks all over my carpet inside floor. And many more problems! *jb thank you, darlene liddane [email protected] 941‑637‑0802

The airbag light comes on. The district manger, jeff westland out of n.j., (609) 395-7308 stated that hyundai is aware of a defect in the right passenger seat (late 1999's & early 2000's that rolled off the assembly) which makes the light come on if a person moves around in the seat, excessive weight of a passenger, or putting any object under the seat. What I find outrageous about this, is the last two times I've taken my vehicle in, I've been told that the airbag light was not on. When I spoke with mr. Westland, he wanted me to leave the car for several days at the dealship, first team, so they could go over it bumper to bumper. On january 8, 2001 I took the car into the dealer so they could look at the transmission and the airbag light which was on again. On that evening, at approximately 5:00, I received a call from the dealship, asking if I could come into the dealership the next morning to drive with one of their mechanics because they could not duplicate the problem with the transmission. I was unable to do so because of work. I was also told that the airbag light had not been on . I picked up the car that evening since, "nothing was wrong with it" and would be unable to test drive it with a mechanic. . I do not understand why the dealership is saying that the airbag light has not been on the last several times when it has been. The transmission sporatically downshifts when I am driving on the freeway on a straight and level surface at a constant speed. It also hesitates sometimes when starting off from a dead stop. If you would like any of the invoices stating the repairs that have been done to these two problems, please contact me. Thank you for your help.
