2014 Hyundai Sonata Owner Comments

problem #8

I own a new 2014 Hyundai Sonata, and my main concern from what I recently have researched is that some of these vehicles are prone to major motor and power train problems, that can lead to fatalities. I understand that the NHTSA has been notified of these problems, and there is a current class action lawsuit pending. What I'd like to ask is, why a recall has not been issued by the Agency, given the grave nature that one of these motors could potentially seize while driving at high speed and can very well lead to fatalities. A personal note: When I first bought the vehicle. In August 2014, it stalled once, while driving at 5-10 miles mph, I took it to the dealer and they found nothing wrong with it. It has not happened ever since.

Hesitation and delays in acceleration when driving from 0 - 30 mph. Originally it started with the rpms dropping way down before catching. Brought the car in for service and they replaced a brake sensor. The problem became much worse. When reaching 30 mph the transmission felt like it went into neutral and had a problem catching. Rpms jumped way up to 4 and revved 3 times before catching. Leaving me unable to have control over the car. Very scary. The car has been at the dealership for a week and will not duplicate the problem when driven by the mechanics and is not throwing any codes. According to the dealership they are unable to fix this because they do not know what the problem is. I am being told to bring it back if it happens again. The majority of my driving is city driving. My commute to work is approximately 30 miles round trip, 5 days a week and seemed to get worse in the rain.

My vehicle has for the last year showed signs of the recall and we have gotten a Hyundai to fix it with a ring but the next day the vehicle showed the same things. The symbol in the middle that displays drive when it disappears the car struggles to accelerate and drive, and when I come to a complete stop with it disappereared the car takes alot of gas to accelerate. Which I believe is from the transmission and the car not being on the same page.. which is terrible as it can cost a lost of life due to the car suddenly stopping and it is a extreme hazard to myself and my family. And I wish that Hyundai would do something or replace the vehicle.

Driving the car the transmission stays in high gear and should be down shifting into lower gear makes a grumbling noise then goes away when at higher speeds 45 plus. I have gone back twice to the dealer and they tell me and the the man that worked on the car thats the 6 speed transmission and thats how it works. I owned the same model 3 years before 2012 and never had this happen. I think theres is a problem with the transmission. Nothing has happen to me or my wife. But something is wrong with the cars transmission. This has happen many times before but dealer states nothing wrong.

Sonata 4-cyl

I was driving on a 25 mph street but when I merge to 50mph highway I notice the engine is not accelerating well, it sound like the gear was stuck to a lower position. Then the problem came when I decided to pull over and tried to park, the shift lever was stuck in the drive position. The car stop when I shut off the engine and called for roadside assistance. The dealer told me that it wasn't connected w/ the recall and they don't know either the cause of it because they told me that it didn't registered in the car computer the code. Just concerned of safety about this car.

I was driving East bound highway 495 to work on 11/13/14 and my car shaken and I found check engine light is on. I was so worry to drive the car and try to pull over nearest exit. And I was able to find a Hyundai dealership near by. I've called Hyundai bluelink to check my car issue and they've told me possible transmission related issue. Advantage Hyundai took my car for service and I had to call taxi to go to work and I was late for my work with my co-worker. We both late for work and I had to go back to dealership to pick up my car. Based on what they've told me that spider web causing the issue which I don't understand. I've lost time and extra money for taxi money. After about 2 weeks later, I was driving back to home from work and my car shaken again and I saw check engine light on my dash board again!!. I was so terrified to drive and pull over nearest exit and drive slow to my home. It was around 7pm and dealership was closed. I took my car back to dealership's service center where I leased this car on Jan of 2014. Same incident happen 2 times in a month and I do not feel safe to drive this car. Also dealer's service center advise me that they don't have part for this car and I have to wait until mid next week. Dealership manager told me they will be no loaner car or rental car they can provide and just told me to wait. I've request dealer to exchange to different car due to safety issue and they can't do that and telling me to contact to buy back my car from dealership, otherwise I have to drive the same car. Main point is I don't feel safe to drive this car. I do not want put myself risky situation. What should I do?

Sonata 4-cyl

  • 700 miles
On May 7,2014 the Sonata was leaking transmission fluid on my garage floor. This vehicle is only two weeks old and about 700 miles on it. When O'brien Hyundai towed it to urbana, Illinois. The service manager told me the transmission had leaked one quart of transmission fluid. He also stated one of the ports had not been sealed at the factory. When pressed he told me the transmission fluid could have caught on fire. He also stated when the car ran out of fluid it would just lock up. Frightening thought of the car was traveling 70 mph. Thanks for your time in this matter.
