Acceleration & cruise controlEngine & cooling

As I was driving down the road at apprx 30 mph. The car would de celerate. I would have to take my foot off the gas and then put back on to get the car to move. Also at the same time the car would bang into gear from park and into reverse. I was told it needed a new transmission. The car was purchased new out of the showroom with 10 miles on it and 6 months later a new transmission. ( Well we were told at the time it was brand new, I have since learned that it was a rebuilt) shame on the dealer for lying...

to customers. The car did ok till about 3 months ago. The car will decelerate and I have to do what I stated above. Then cant get out of park and the traction control light comes on. This has happened numerous times. A new brake switch was put in and the car was fine for 7 full days and on the 8th day same thing. So back we go to the dealers and they are really rude and not happy to see me at all . ( I don't' want to see them either) I was told same problem and another switch has been put in this is the third one. The other issue is we are not being notified of recalls. And the dealership is so rude. Will never own another one. *Tr

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. *Tr

cannister,purge valve,gas cap. They state they also cleared the codes to pass inspection. But, again I had to drive my car another 50+ miles again so that they could reset the monitors. Engine light was off, which was a good sign. This cost me $508.00. However, the next morning,i started up the car. It started very rough and felt like it was ready to stall out on me. Engine light came back on also. Visit #3- on, 1/8/08 took car back again,explained what happened. They said to leave it overnight. The next day, service manager calls me at work. She tells me that their was a #4 cylinder misfire code, needed a fuel injector,spark plugs, plug wires,timing belt, serpentine belt,belt tensioner,oill change and fuel injector service. Estimated at least $1200.00. This was very upsetting. I declined all work and file a customer complaint against them. My car was running fine when I took it the first time. This is an unfair practice by these people and they need to get reported. Perhaps, their mechanic triggered something on the codes to create these problems all of a sudden. I need your help or some advise on how to further pursue this problem. Thank you for your cooperation. *Tr

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. *Nm

My 2001 hyundai sonata was bought new. It has given me nothing but problems from the time I drove it off the lot and as soon as I hit the 60,000 mile mark (the bumper-to-bumper warranty ended at this point), the car constantly has something wrong with it. I have spent thousands of dollars in repairs. The airbags were fixed by the dealer because there was a problem. The brakes had a loud squeak and dealer replaced (under warranty at that time). The side front window motors have been fixed twice and now the...

passenger side window motor is broken and I had to put tape on it so that it will stay up. The timing belt went out after the warranty. Some kind of coil broke and needed replacement. The engine light is always turning on. I stopped taking it to the dealer after the car broke down, had it towed, dealer in laurel, md claimed to have fixed it, charged me $768, picked up car, same problem, engine light still on and took it back to dealer. Dealer said there was yet another problem. They said they fixed it and they charged me over $500. Still the same problem. I took the car to a mechanic and was charged $45 for the repair. There have been several other problems that I have had to pay for repairs. I just spent $435 on another repair. Now, after each repair, I just wait for the engine light to turn on again for the next expensive repair and yet I'm still making car payments. Absolute worst car I have ever had. *Jb

Dt*: the contact stated without warning the vehicle stalled, on five occasions. This happened while driving at no particular speed. The vehicle had to be pulled over and towed to the dealership. The final time, the dealership determined there was a rotor in the crankshaft sensor that was dented. The crankshaft sensor was replaced. Also, a puddle was noticed under the vehicle. The dealership determined there was a rupture in the power steering line and the line was replaced.

I was told that the timing belt had failed causing catastrophic damage to the engine and that since I now had 60255 miles on the car, and had not had the timing belt replaced, the 100000 mile warranty was void and they would not cover any damage. I was informed that the damage to the motor was more than $5000 and hyundai was not responsible for any of that cost.

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.*Ak

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 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. *Jb

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.*Ak

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.

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! *Ak

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.
