Lower oxygen sensor malfunctioned, causing the "check engine" light to stay on. I have been returning to the suntrup dealership in missouri every since I purchased the car for the same exact problem. And the problem is always the oxygen sensors. I have a 2001 hyundai sonata and I have been having the same problems over and over. I had an extended warranty that I purchased with the car for $1,300.00 and I find out on my last visit to the dealership that the warranty company filed bankruptcy. So now I have no warranty on my car and I have lost money for no reason.
2001 Hyundai Sonata engine complaints
Page 2 of 2: complaints 11 to 24 of 24, newest first, as owners wrote them.
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 $135.00 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. *ak *sc
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. *ak 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. *sc
Engine misses and backfires through the intake. The major problem is when the engine is running and it doesn't matter if it is in park, or if you are driving it. I was on my way to work when it malfunctioned. I was sitting at a signal light when the engine accelerator went up to 4200 RPM by itself with no foot on the pedal. I almost got into an accident, I pressed harder on the brake pedal and had to take it out of drive to avoid hitting the car in front of me. The engines rpms change a lot now and will not idle right at all; this car is not safe to drive with these engine problems; and should not be on the highway. I had a pennsylvania certified inspection mechanic look at and drive the car; and he said the car is not safe to drive; and if it would have been due for state inspection that it would have not passed; but failed and would be illegal to drive.
I bought my 2001 hyundai sonata less than 2 years ago. Since that time I have had to replace both window motors, front and rear brakes, timing belt and all tires. I would have thought that a brand new car would be trouble-free (that's why I chose hyundai, because of the great warranty) however, it appears that is not the case. My car recently broke down on my way home from work, had to be towed and was in for repair for a week (timing belt), which was a huge inconvenience and expense for me. I am now looking for a suitable trade-in for my hyundai and would not recommend one to friends and family members.
Engine check light comes on intermittently. Dealer has replaced a sensor three times.
The vehicle stalled without warning while driving.
The vehicle stalled, which caused the vehicle to abruptly pull. *jb 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.
Engine making loud ticking noise/loses power/quits. Repeated repair attempts by authorize dealerships (jim ellis hyundai-770‑458‑6811) failed to correct the problem. *ts ***dimsii ivoq entry posted after 12-12-02 cut over to artemis***761399
With less than 1300 miles on the vehicle, it began to buck and surge in traffic at 65mph, and the tachometer began swinging wildly from 0 to 2500rpm. After getting off to the side of the road quickly, where it stalled again and again, I called hyundai roadside assistance for a tow to the dealer. They examined and drove the car, and told me it wasn't acting up for them, and suggested I take it home while they ordered an exhaust purge valve per a 2.4l engine problem service bulletin from hyundai. While on the highway toward home, it began bucking and the tachometer was swinging wildly again, so I got off to the side, where it repeatedly stalled, and again I called hyundai roadside assistance for a tow back to the dealer. They rented a car for me, and over the next week replaced the purge valve, but the car also died on them, so they did a more thorough analysis, which showed a failed crankshaft position sensor, which caused ignition spark failure. After replacing that, they called me to come get the car and take it home. This time it failed just as I reached my driveway, again bucking and stalling with the tachometer swinging wildly up and down. For a third time, I called roadside assistance for a tow to the dealer, which promised a search to determine the cause of the failures, involvement of the district manager, and an attempt to obtain a different sensor model in case the batch of available sensors was "bad". Subsequent phone calls to the dealership have not produced any answer as to the cause of the failures, delays in obtaining a suitable replacement part, and so far, a total of 18 inoperable days for my new car. This failure is a serious issue; a person at the dealership told me that "other (hyundai) vehicles with the same engine had the same problem" one of which was there while I was at the dealer waiting for my second rental car. I repeat; this is a serious safety issue; such sudden loss of engine power in traffic can have fatal results!
The main pulley came disconnected and fell off onto the street with no waring whatsoever. Luckily I was preparing to turn left and was stopped in the left turn lane. There was a bad thunk and shake and the car shut down. Had I been moving, it could have been a very different story, especially at highway speed. It is a brand new car, I just had the oil changed. Everything was fine, I thought. I was told that this was a serious problem that should be reported to you.
While driving at any speed during normal operation vehicle fails to start, problem is intermittent. Dealer has examined vehicle numerous times, and failed to remedy problem. *ak engine light illuminated and then vehicle began havinb problems with no power, stalling, and making noises, dealer replaced the purge control valve, however problem till continues. Brakes feel low to the floor. Center AC vents and right passenger vent broke, dealer replaced. Dealer adjusted drive belts due to being noisy.
When driving vehicle would have a coking sound like it wanted to cut off. With no prior warning vehicle cuts off in traffic when slowing down. Also, after cutting off, vehicle will start back up.
Engine failed at 1633 miles going 65 MPH on major highway. According to hyndai service there is a problem with engine sleeves in early production engines. Sleeves come loose causing pistons to smash spark plugs. New engine installed, but did not run properly. Hyundai service ordering second new engine. Problem diagnosed quickly due to another 2001 santa fe with 3900 miles in shop with same problem. Peoples hyundai in folsom, ca were very helpful.
