Hyundai installed a software update on our 2014 Sonata due to engine fires about a year ago. This software update resulted in the car going into what is called " limp mode" and the malfunction indicator light coming on which results in the car losing acceleration and not being able to climb hills. This occurred when the car was being driven on the highway at 65 mph. Once the car went into limp mode it would barely go up hills and presented a hazard on the highway. When I called the dealership they told me my car was no longer under warranty for anything other than engine or drive train and that they would not tow the car into their shop. They also told me I should not drive the car. I had the car towed to a local shop and they diagnosed the problem as a P1326, which I had to pay for out of my pocket. The mechanic told me there was a recall on the motor and it would have to be replaced. I then called the dealership and they agreed to tow the car to their dealership. After the dealership diagnosed the problem they informed me the software system detected a noise in the engine and went into limp mode to protect the engine. They said everything was fine and that the malfunction indicator light and limp mode were a false positive due to the software update that was installed. When I pointed out the inconvenience this had caused me I was told this happens all the time and I would have to get used to it or sell the car. I only have 64,000 miles on this vehicle and I no longer have any confidence in this vehicle to commute long distances. The issue with these false positives and the limp mode needs to be eliminated.

2014 Hyundai Sonata with VIN # [xxx] has had campaign recalls which started 3/ 2019 ( campaign recall123 powertrain transmission/transaxle). Vehicle received repair for campaign recall 123 10/2014 under Hyundai dealership. Recently car stalled while driving and got diagnosed by Hyundai dealership that engine seized and would need new engine.car was underwarranty with the campaign recall and stated that car would need transmission due to 3rd shift not working like it should. Caseworker from Consumer Affairs stated that I would have to pay for transmission due to transmission not under warranty and he would not approve for repair. I had mentioned to caseworker that campaign recall 123 had been repaired by Hyundai back in 2014. He denied any approval. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

In July 2019 2014 Hyundai Sonata as I was driving vehicle stalled. Again in September 2019 vehicle did same thing. Prior to that as I would put vehicle in park and turn off engine the shift nob would not completely be in park position. It would make a noise like it shifted. Took it to huyndai dealership and they were able to approve warranty for engine, but then stated it was going to need new transmission. And that the 3rd shift was difficult. As I look under recalls I see that campaign recall 123 was done 2014. However upon researching came across if dealership repaired a recall and it failed they should have been able to repair the problem. Unfortunately I was not getting anywhere with Consumer Affairs and getting recall campaign 123 repaired.. I needed vehicle running to get to work so since Hyundai didn't want to repair something they supposedly billed out. I had to pay out of pocket for transmission repair.

I purchased a car from Toyota of hollywood in March of 2019. At the time of purchase the dealer kept vehicle for 1 day to make service repairs to the brakes. I brang vehicle back to the dealership in April of 2019 because of noises being heard from car ( brake noises, rocky noises, water rushing forward) but was told by service manager that noises were normal. I brang vehicle back to dealership in August of 2019 at 8am because of additional noises being heard from car (explained to employee) but was told to make an appointment. I called and made an appointment for the same morning at 9am. Car was diagnosed with multiple issues ( brakes, rotors, axle). Management (ray and michael ) made the decision to hold my car without consent due to safety issues. It has been held without my consent since Friday, August 30th 2019. Bid patrol was called by managers because they did not want to speak with me or release my vehicle and asked the patrol that I leave premises without my car. I have made multiple attempts to contact the dealership by phone, email and an in person visit( with police escort) but have been unsuccessful in obtaining my vehicle. Visited dealership on Monday, September 2nd with a police escort and was not allowed on premises. Manager would not speak to me, would not release vehicle and requested I contact service manager michael. The service manager did not respond to any of my calls, voicemails or emails throughout the week. On Friday, September 6th 2019 I made another in person visit( with police escort because managers did not want me on premises) and managers did not want to speak with me. An employee was sent in place of manager to speak with me and I was able to obtain my vehicle but none of the safety issues were fixed( brakes, rotors, axle). I was given documents I did not want to sign but signed only to get my vehicle released to me.

No warning.from the car.now the car will not turn off even with key out of car it will try to start and keeps trying to start.I had to disconnect the battery to get car locked. Brakes failed car rolling and used emergency brake to keep car from rolling. Towed to local Firestone and the reading was not done bc the obd was found just hanging there. Car has only 51,000 miles. Very dangerous I could have been rear ended. I could have had my children with me.if this had happened on the express way I would have likely caused a very hugh accident.

On 4/24/19 at approximately 5:00pm, I was driving down a busy city driving when my check engine light came on followed by all of the lights on the dashboard blinking. I drove into a parking lot and my car completely shut down on me. It would not turn on or start at all. I had to use my car insurance to have my car towed to my friends house because the Hyundai dealership was not within the towing range to be covered by my insurance. I called the Hyundai dealership service department at the very beginning of the next day, 4/25/19. The dealership came and towed my car to the dealership. After the inspection, I was notified that I suffered an engine failure and the engine had to be replaced. I was provided with a rental car, which I can use until my car is fixed, but Hyundai will need to send them a new engine so they dont know yet when the car will be fixed. I was also told that I would have to pay for the hoses, gaskets; anything that wasn't either a black surface or metal because the warranty does not cover those. The estimate for me to pay would be around $300. Also, during the inspection for the engine, I was told the axels were leaking and those needed to be replaced including all of the components of the brake system. I would have to pay the $50 deductible and the warranty would cover the rest. When the car completely shut down while it was still moving was very unsafe, especially during rush hour traffic.

I took my vehicle to the Hyundai dealer and requested an emissions inspection, a safety inspection, a correction of all recall maintenance items, and an oil change. I told the representative that I did not want to order the 60,000 mile service since I still had not reached the 60,000 mile mark, and wanted to wait for a short period since my daughter's college tuition was due this month. The representative requested and drove the vehicle for approximately 40 miles as part of the emissions test and completed all requested services. I drove the vehicle home (approximately 10 miles) and parked it in the garage. The next morning I entered and started the vehicle; however, the gear shift was completely locked and I could not release it. Moreover, the check engine warning light on the dashboard appeared. The check engine light was not active prior to executing services. The car was parked on a level surface in the garage and the gear was properly placed in the park position. The emergency brakes were not engaged because the vehicle was not on an incline. A check of the internet revealed that the problem is occurring in a number of Sonatas; however, there is no recall for this defect noted on the NHTSA's safety recall site.

Engine began to slow down...I pulled off the freeway safely as the car beeped and displayed a warning: 'hybrid drive failure. Place car in P. do not drive' they should also add, call a wrecker, in all fairness. Waiting on Hyundai's answer. After tractoon issues in ice and snow in addition to this...when I get this car back, she's a goner! I need a real vehicle.

Motor began to fail on the highway. Pulled over. 'hybrid drive failure. Place in park and do not drive.' The warning should also have added 'call a wrecker.' Dealer says Hyundai is looking at pictures. Car was serviced twice and oil changed regularly. Waiting to see what Hyundai says.

I was driving to pick up my friend and her son, when I notice the car was revving up as if it was in the wrong gear. Then it got worse as I kept driving because the car began to jerk as I tried to pull off, and when it checked the gear, it was stuck in the fourth gear. After rushing to get back home my check engine light came on and I started searching to figure out what's wrong. I noticed a previous recall but when I told key Hyundai about the problem, I was told my VIN number was covered by the recall

The contact owns a 2014 Hyundai Sonata. While driving 80 mph, the vehicle failed to accelerate while depressing the accelerator pedal. Also, the rpms increased and the service engine warning indicator illuminated. The contact pulled the vehicle over, turned it off and restarted it, shifted into drive, and the vehicle operated normally. When the failure occurred, the gear shifter was not registering a position such as drive or park. At times, the vehicle fails to downshift. The contact called drivetime used cars (8341 Indiana ave, riverside, ca 92504, (951) 353-2277) where she recently purchased the vehicle and was advised to take the vehicle to pep boys in san bernardino, ca where it was awaiting diagnostic testing. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,000.

Takata recall - car is blowing out smoke - in 700 miles it has lost 2 quarts of oil, it has under 50K miles, it is covered under 2 different recalls thru Hyundai but they refuse to replace the engine, when you try to accelerate - the car will hesitate and then all of sudden blow smoke out the back - so much that you think the car is going to catch on fire, we have had it in the dealership 3 times already - contacted them other times in between. Now when trying to accelerate at just 1 RPM smoke comes out the back car starts shaking like its going to stall out check enginge light comes on - a few seconds later big cloud of smoke comes out back and car will then move leaving trails of smoke behind. Check engine light went off. Hyundai said unless the check engine light is on - it wont matter. They just want us to do a oil consumption test - the engine is making a knocking noise. Hyundai has heard it too. We leave so much smoke that we cant see a car behind us. It can barely make it to accelerate on the highway. 6/21/17 - massey Hyundai hagerstown 7/18/17 - massey Hyundai hagerstown 8/28/17 - massey Hyundai hagerstown Hyundai case #10553414 - they know about it! we have had it towed to the shop 2 times now.

My safety issue is that my vehicle would not start unless it is in neutral or it would not shift at all. It happens when I am in park or when I am driving it is in drive but goes to neutral on its own. So while I drive and it does that I have to shift to neutral and then back to drive. Sometimes I will be parked and I turn on the car and it won't shift at all. I have tried to take it in and I have called the manufacture and no one thinks it is a safety issue because they keep giving me the run around. I have taken it in and they told me that it was not listed on my appointment. Shouldn't that be priority?

Brought car in for service and mentioned issue with slipping transmission. Was told there was a slow leak and it would need to be replaced under warranty. Transmission was replaced but the same symptoms still occurred. Dealer then replaced the transmission a total of 4 times before giving the car back to me with the same problem. After an escalation to corporate and many months of back and forth I receive an urgent phone call to bring my vehicle in immediately because the computer system apparently had the wrong part number in it and the transmission they had been putting in all this time was the incorrect one. I am currently still waiting for the vehicle to be returned to me once again with the right transmission in it and see if the problem is now corrected. However, I have no idea what residual issues the vehicle may now have based on having the incorrect transmissions in there for more than 1000 miles.

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.
