Unfortunately, at 50,000 miles my car began having major issues. It has been less than a year, since I bought my used car, and it is having major mechanical issues. Every time I go from parking to drive, or drive to reverse, my car jumps. While on the highway it jumped in motion. After that incident I was afraid to drive my car again. My mechanic told me it was the transmission. A new transmission costs over $3,000 dollars! I am a student and do not have that money, nor will I have it anytime soon. The dealership that sold me the car, gettel hyundai of charlotte county florida, never advised me that hyundai's have been know to have transmission failures. I invested money into a car that I cannot drive because it was faulty when sold to me.

The transmission needs to be replaced.

48 hours after the dealer replaced two selenodes and wiring harness (stating it could be my driving habits, but would file it under the warranty) - the vehicle starting shifting even harder than it previously had and then suddenly would not go over 25mph and the rpms were 5-6. Luckily was able to get vehicle to the dealer (I am the original owner) - and was told it now needs a new transmission. I had zero issues with my vehicle till it hit approximately 75,000 miles. I have filed two other complaints on this website regarding the other two incidents that I've had warranty work done on in the last 3 months. I expect that this vehicle will completely fall apart by the time I hit 100k and there is no longer a warranty. I am very fortunate that I did not have my 3 kids with me this last time.

The first time I thought something strange was going on with my new car (purchased with 16,000 miles on it) at the 18,000 mile mark. . The car was stuck in 4th gear and would not change gears with the auto stick or with the pedals. I stopped the car and tried to pull out in traffic but had no power. I pulled over asap and turned the car off (rebooted the car) and everything worked again. On the dec 17th,2011, (3 weeks later) I was pulling out of a friends house at 10pm and everything seem normal. However, as the car got to about 15mph the tach raced over to 5,000 rpms and then I heard a loud slam and the car shot forward. I recalled the last time the car acted strange so I checked to see what gear it was in and sure enough it was again in 4th gear. When I tried to change gears it would not change gears just as before. I pulled over and tired to reboot the car again, but this time it did not fix itself. I had to drive 30miles home, so I got on the interstate and headed home. The tach raced a few times, but because the car stayed in 4th gear I make it home safely. When I got home I discover the reverse was gone out as well. Now for the good news, I researched the issues one this and a few other site and discover I was not the only one with this problem. I took my car to the dealer this morning and asked for a new transmission. The service tech got me a loaner in less than 30mins I was on my way. Same car and color. I got a call from the dealer a couple of hours later saying they were going to replace the entire transmission. While and I not happy that my new car required a new transmission after only 3500 miles of me driving it and under 20,000 total miles, I am very happy how the dealer handled the entire issue. Hats off to eastern shore h of daphne, ala and thank god I got the 100,000 extended warranty. Will up date when I get my car back in 5 days.

On 12/2/2010, I was driving at highway speed (approximately 60 MPH) and the car violently jolted, as if I had run over a large object. If I had not had both hands on the steering wheel, I might have lost control of the vehicle. Subsequently, I was able to drive the vehicle, but it seemed to be over-revving, as if it was stuck in the wrong gear. I returned the vehicle to the dealership that night. After reading the computer error code, the service manager indicated that they would have to replace the transmission. I was provided with a loaner vehicle. On 12/8/10, I received a call from the service manager. He stated that in these circumstance, the transmission is typically replaced with a rebuilt transmission with a new housing. He indicated that the dealership was trying to obtain a new transmission for me. They were experiencing difficulty because there was 80 some requests for new transmissions and only 70 some available (county?, state?, central florida?) updated 01/20/11

While driving my new 2011 hyundai sonata gls sedan with 200 miles on the odometer, the transmission failed completely when a transmission hose blew off releasing all the oil out of the transmission. Once at the dealership they showed me that hose clamp for the hose had never been attached correctly at the factory! The car is at the dealership for repairs. It is not know at this time if the transmission has been damaged due to the loss of oil. We were not hurt and didn't lose control of the car. This incident occurred on a flat piece of highway, should it occurred in hilly terrain or passing another vehicle the results could have been much different since the car became inoperable. Very disappointing since the car had only 200 miles on it!
