1 day after buying vehicle. It failed. 1st dealer replaced 12V battery. Then drove 17 miles and it failed again. Dealer determined hybrid battery bad. 7K for new one. 7 yr old vehicle needed new hybrid battery. Purchased hybrid battery. 1 year later vehicle started jerking on highway. Then it could not get over 40 and engine was revving high. Towef to dealer. They determined failed transmission and electric motor. Purchased used parts and had them installed for 4K. Nightmare vehicle. Awful support from Hyundai. No way I would ever buy another.

I had my engine replaced in 3/17. A couple months after that, it started hesitating when I put it in reverse. A couple months later, I had no reverse. I took it to the dealership in beckley, wv. They told me that they ran a scope in it and there is no reverse gear there. I was told of a recall on the power train so I called Hyundai. They sent me to the same dealership and I was told the same thing, I had no reverse. I was also told there was not a recall on my vehicle for this issue. I've been driving for almost 4 years with no reverse. I don't like to complain but I don't know what steps to take.

Sometimes when I press the gas, the car will basically take an extra second to speed up, and probably 70% of the times that I press the brakes to slow down or come to a stop, itll (also) take an extra second and itll stall/jerk 1 time, then finish slowing down or stopping....its gradually been getting worse as time passes...the engine needs some work definitely! (I'll feel much more safe after this engine recall is fixed!)

My engine threw a rod at approx. 85000 miles (10/2019). Hyundai replaced the short block but since then I continue to have issues with my car. After they replaced the short block and I picked my car up, the car seemed to be running like it is not getting consistent fuel like it is supposed to. I have had it in the shop 4 times because the check engine light has come on. While I am driving, the car seems to lurch at random times and this issue has gotten so bad that this (what I call lurching) makes the cruise control shut off. One time I was using the cruise control to accelerate onto the freeway and the warning bells and whistles went off, the car stalled, then restarted itself with no check engine light on. The most recent time (10/26/20 - 11/10/20), they had my car for 6 weeks, they did not fix it. They put 337 miles on my car while they had it and I experienced the same issues I have been complaining about to them since the beginning, after I drove it 38 miles. They cannot seem to find what is wrong with my car or fix it. 10/2019 threw rod - replaced short block see attached 1/3/2020 replaced hsg belt - did not fix issue see attached date unknown - check engine light went off before they could run codes.unable to find issues - did nothing no paperwork 7/3/2020 - unable to duplicate concerns, provided software updates. 8/20/2020 I called san tan Hyundai and told them I continued to have the same issues. I told them I needed a loaner car as I have no other means of transportation. I was advised they did not have one available but would call me when they did. They never called. The check engine light came on again on 10/25 while I was out of town so I took it to them 10/26. I have paid for 2 rental cars now while trying to get this issue resolved. 10/26/20 trans reset recycle cleared codes - did not fix issue see attached

My car stalls, lags and shuts off while driving and has a strong scent of exhaust and uses an awful amount of oil but there are no visible oil leaks. There are no check engine lights on. I have taken it to the muffler shop who states no exhaust leaks are found. My local gateway and mike morgan hyuandi says it throws no codes when put on the diagnostic machine so I cant find out the issue. From research I see this is a common issue with this model cars and I feel this should be looked into because it is a hazard especially when it kills in the midst of traffic

While driving 25 miles on walnut St in rialto ca.all of a sudden my hybrid Hyundai Sonata made a grinding noise and stop responding I avoid hitting a car infront of me and approached the side walk messing up my right front bumper, when I finally stopped I put the car on park and it made a nasty grinding sound. I tried to put the car on D and it wouldn't move I put it on R and nothing. It was a very scarry experience, I want to know if there is anything you can help me with if there is a recall on the transmission because thats what it sounds like. I had it towed to my house because the gears are not workingit. It has 149346 miles

Hybrid system warning, shut off don't drive!!! light came on car shut down while in reverse, it was fine in drive! took it to the Hyundai in mesquite tx where I've had numerous issues in the past but had to go somewhere close! they couldn't find a diagnosis went through all the codes, said it wasn't shutting down for them and it was an oil pump and oil assembly $1,904.49 minus the $150 diagnostic to not even tell me why it shuts down in reverse giving a whole other issue with the car that isn't a part of the reason I took it in! never again will I buy a Hyundai!

My 2012 Hyundai Sonata received a replacement engine due to a recall for excessive oil consumption. My car did not have any other problems, everything else was running as it should. After my engine was replaced, the dealership did a test drive and said everything was running well. I drove my car home everything seemed ok. I only drove the car to my local supermarket twice and lastly, my son drove it out to a best buy, which was 40 minutes away. Everything was normal during the drive on the highway as well as the local street until he pulled into the parking lot. As soon as he made the turn in, the car started to rev in an extreme way-taking the RPM needle to 6 and a little over- with very little application to the gas pedal and very little motion from the car. He parked the car then turned it on again, the engine turned on ok, but the car would not go forward or backwards. The car was towed to the dealership and after 4 days was told I need a new transmission. There were no indications, whatsoever, of issues with the transmission, and the sudden stoppage is very disconcerting to say the least. Are there issues with this model's transmission, as there were no signs of deterioration" my car has 145,000 miles on it. I contacted Hyundai hq customer service and a case was made, only to get a call from the case mgr. Stating the transmission is out of warranty and there is nothing they can do. I understand I was given a replacement engine, but I fail to understand how it's even possible or even coincidental that my transmission would collapse after a major repair. The dealership told me that the diagnostics history shows there was an incorrect ratio in gear 3.why were there no warnings or telltale signs" this could have turned out very badly for my son had it happened just a minute sooner while he was on the highway.

I purchased a 2012 Hyundai Sonata in January 2012. In 2014, a recall of the car was issued for a shift cable problem where the cable would detach from the shifter. I took the car to the local Hyundai dealer in September 2014 to have the recall repair completed. In 2018, I gave the car to my daughter so my grandson could participate in high school activities, sports and attend classes at the community college. After his graduation from high school, he is attending the univ. Of Maryland in college park, md, as a resident student and only uses the car on weekends when he comes home and during breaks from college semesters. The reason for this complaint occurred in late June 2020 and is the exact failure mechanism that caused the 2014 recall. Apparently the recall fix was either not a permanent solution or was not done correctly. The result is my daughter had to pay $974 to fix something that should have been taken care of in 2014. The problem was a result either a poor original design or the recall fix was only temporary. I called Hyundai customer service and was told that the car was not covered under warranty because my daughter was a secondary owner.

Engine started rattling while idling. Sounded like there was something lose in the engine. Looked up the VIN and discovered there was a recall for that problem with Hyundai. Havent used the car since. It had been parked. Fast forward to today 5/3/2020 and discovered that the recall was gone.

In motion going 20 mph passenger side air bag deployed without accident. Air bag busted on my head, back, and right side of my face. With a powdery sharp film on me. Air bag recall was not fixed by the dealership. I reported it to Hyundai which lead to countless email with no repairs made. Seat and door panel is ruined with a crack in the windshield that has spread. Engine had been stalling and producing white smoke from the tailpipes. While in motion car completely shuts off and will not come back on. Dash board lights up goes off comes on displays key not in vehicle when the key is in the armrest plugged in. Brake pedal freezes up preventing the car to start. Radio does not work check engine light blinks on and off when car is in motion. Reach out to Hyundai webb on route 30 in merrillville, in. They had the vehicle for a month due to the engine recall and turbo recall. They forced me to pick the vehicle up after having it for a month. In motion from the dealership the car cuts off. I get it back on a big cloud of white smoke produces and cuts off again while in traffic. Prior to picking the car up the manager of the shop called informed me to come pick it up and bring a battery due to the battery in the car is dead. The car is at the dealership...they did not have the courtesy to charge to battery to test the work that was done. I take a battery up there they keep the car for another week or 2. when I pick it up the armrest is broken they put a screw in the positive cable post to hold the post in place; I guess. There are ashes on the floor as if someone was smoking in the car, put different color antifreeze in the antifreeze reservoir; meaning they mixed the fluids that would cause more problems. I called the manager again immediately and told him the car is doing the same things. Told me to drive the white smoke out, car is not safe to drive don't stay running.

The contact owns an 2012 Hyundai Sonata. The contact stated while driving 55 mph the vehicle shuddered and stalled. The check engine, oil, and the transmission temperature warning lights illuminated. The contact pulled over abd observed white smoke coming from the under the hood. There was also an odor of burning plastic. The vehicle was towed to the residence. The vehicle was not taken to be diagnosed nor repaired. A dealer was not contacted. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

My vehicle is not recognizing that it is in park so it is not completely shutting off.

The brake lights are remaining on even if brake pads are not being depressed. While driving or in park. The car also will stall while driving down the road.

Loose power and noise from engine while in drive 60 mph....donot know what it is for sure.happens in city streets turning an driving at the same time.

- La Mesa, CA, USA

"hybrid system warning safely stop and do not drive" message come up on the display. This has happened three time. The first time at a stop light, and the motor kept revving and would the car would jump forward while pressing the brake. After getting off the road, parked, killed the car and cranked it back up. The message cleared. I turned the car on and off a couple times and made a trip round the parking lot, stopping, sifting gears, etc... with no luck of duplicating the issue. The second time two months late, I was just parked and the message came on as I was killing it. I tried cranking the car but kept getting the error and the eps came on but the car didnt crank and could not get it out of park. Multiple on and offs the car full cranked up and was able take it out of park and drive for test spin around the parking lot, test the gears from D to P.. never got it to do it again. A week later driving down the freeway the light came on and had to pull off on the shoulder. Turned the car on and off and all the lights cleared. About a month later got in the car to got work and the same message came on along with a check engine. The car cranked but the message wouldnt go away after multiple on/off's and shifting of gears. I should mention that when you shift through the gears the the light on the dash line up. I never have problem while switching gear from P to R or drive. Most while driving/stopping or after parking going from D to P. looks like it will be towed in to the dealer now.

Car stop in the middle of the road when I tried to accelerate the was making a loud grinding noise. Prior to being on this road I was on the highway for about 35-40 miles before it stopped and wouldn't move. When I would put the car in reverse it would make a loud clicking noise. I called Hyundai they said that there was no open recall related to this issue

- Middletown, PA, USA

Driving at interstate speeds, will down shift and drastically lose speed while in blue mode. No warning lights of any kind. No apparent issue at lower speeds. Engine does not rev up high because of rev limits. Drops from 6 gear down to 4 gear quickly loosing speed. Leading to impedance of traffic flow. A couple of time this happened when merging on to interstate. Had to ride on side to next exit. I have learned if I go into sport shift mode I do not experience this issue. I have taken to dealership, but unable to repeat issue on test drive. They did a diagnosis and cleared some history codes but it did not help. Again this happens unexpectedly.

- Waterloo, IA, USA

Vehicle shifted funny, then check engine light came on. Almost got into an accident. See service bulletin number 14-at-010. Apparently this is a known and ongoing problem. I was told by Hyundai that there is currently no recall.
