They changed my oil and informed my mom of an ongoing issue. Well get off headed home, on regular county road headlights flashed off and on alone with radio console.

Tried to replace it and the wire was hot and bulb wouldn't come out. So, I decided to wait till I get home. But now I'm waiting on the side of the road because my engine light is

Sonata

  • 105,000 miles
After driving for a few minutes on highway, my 2012 Sonata hybrid will start to jump and buck. It slowly loses power and when it reaches lower speeds (under 40 mph) as I try to accelerate it will feel like it's trying to catch the next gear but won't. I will continue to lose power so I have to try to leave highway or pull over, which can be dangerous on a high speed road. It has happened three times since August 2018. Just took back to dealership but first two times they said they could not replicate problem while test driving it and all diagnosis indicated the car is fine. I see in some web sites that other users nation-wide have had the very same problem but with no resolution at hand. This is a very concerning safety issue as the last time it happened the car behind me almost run into me as my car lost power and speed rapidly and started to buck/stutter.

"takata recall" 9/29/2017 my 2012 Hyundai Sonata 2.0T engine started knocking while driving and also lost of power while accelerating. I called the dealership who usually works on my car and they told me to bring it in. Come to find out they said the motor was locking up and they wold submit a form to Hyundai to see if they would replace my engine. 07/05/2018 my car has done the same thing and the dealership is refusing to replace the engine this time even though its been less than a year since they replaced it last time and I have been regularly getting my oil changed.

The car hasn't been working properly in the last few months so I pulled up the VIN number and noticed that the car had a few recalls went to Sonata cfl in clermont they said they couldn't fix anything because the engine light was on but that they fixed the airbag recall. So I'm still running my car, which is my only means of transportation with an airbag and engine light on. I'm scared for me and my children. I called today again to seek assistance or somewhat of answers of whats going on. They shared with me last time that my car had to many mileage that at the time had about 120436

Sonata

  • 126,000 miles
I pulled out into traffic on a city street and my car revved up between 4 and 5, and than all lights on dash lit up and my car died. I coasted into parking lot (safely thankfully) and car started smoking so got out immediately. My car was towed to local repair shop who replaced starter which was what they believed it to be. Turns out it was not starter it is engine that will need to be replaced. I looked into recalls and contacted Hyundai customer service who informed me this engine recall had been completed already. I was directed to dealership to follow up on what options there are as 'extended warranty' only covers up to 120000 miles which my car is over. The repair shop I went to mentioned there was no oil on dipstick when checked which is concerning to me as that seems to be what result of recall that was completed would result in, along with other symptoms like dash lighting up which I read from other reports. I am always up to date on getting regular oil changes at 5000 miles they now recommend instead of 3000 miles (which dealership records will show), and was not at 5000 mile point so that should not have been an issue. I also do not recall being informed of any oil leaks or concerns for this vehicle that I would have needed to keep an eye on. I have yet to follow up with dealership as it is holiday weekend so will see what they are able to do. I want to know who to contact if a recall does not fix the problem and what next steps are to help me as a consumer who always takes care of car. A cars engine should not be bad at under 130000 miles and too many similar symptoms to not have it followed up on and manufacturer take some responsibility. I am going to have to have repair shop fix it and get reimbursed unless Hyundai dealer is willing to have it towed so they be responsible and strive to provide honest customer service and stand behind their car.

Sonata

  • 80,000 miles
I was driving my 2012 hyundia Sonata down the road, and all of a sudden, the whole car shut off. This caused the steering wheel and the brakes to fail. Fortunately, I was able to make it to the side of the road, and I smelled smoke. At first, I thought the engine was overheating, so I opened the hood to see what was going on. I saw a ball of fire, and quickly grabbed my 4 year old and 10 year old out of the car. By the time I got them out of the car, the whole engine bay engulfed in flames. After telling my story, I have had multiple people reach out to me with similar stories.

Sonata

  • 36,000 miles
While driving in motion or after driving briefly after a complete stop. The emergency brake light may come on, or the actual brake lights would start to flicker for no reason. The rpms on the car would drop very low and then rise over 3000. The vehicle would then decelerate and not allow to go higher than 25 mph. The engine also makes a knocking noise. This has caused two near accidents, one being T-boned by another vehicle and another almost being hit in the rear of the vehicle by another vehicle. This has been stated to the local dealership at least twice and they state they cannot find anything wrong that would cause these issues. The vehicle has been taken to taylor Hyundai of augusta each time to be inspected.

Sonata

  • 105,500 miles
'engine seizure'I was drving my 2012 Hyundai Sonata (105,000 miles) on my way home from work, and suddenly after a quick passing effort by me rendered the car dead, all the dash lights came on and while I was mid way passing the car I had to break a little and pull up on the side (still on the main road). Turned off the car completely and tried turning on, but nothing happened. Got it towed to an auto shop and the mechanic said all the engine oil had drained out and the engine was locked out. Now an oil change was done about 4K miles/3months prior to the incident, an oil change was imminently near but this should not have happened after 4K miles of an oil change. After reading up, seems like this is a common issue with this Sonata, and my car had gone through an engine recall at a dealership 9 months ago, and nothing got picked up there. Hyundai needs to fix this issue asap. Scariest thing is this could have happened on a highway/vacation/with my family members in the car, it is not a small issue as it might sound

Takata recall. My son was driving down a major state route at 9:30pm when the car suddenly lost power, shortly there after, it stalled out, all the dashboard lights went on and within 2-3 mins, smoke poured from the front of the car and within 2 mins the front of the car was one huge blaze of fire. He was lucky to get out in time. It was very traumatic for him to say the least, not to mention as his parents, we were on face time with him after he pulled over and saw this as it was happening and couldn't be there to assist him.

Sonata

  • 155,000 miles
While my car is in motion it does not accelerate properly. A check engine light come on shortly after. The car will rev up to 5000-6000 RPM with very little to no acceleration. Apparently a common issue with the Sonatas with turbos. I was told it's the waste gate actuator for the turbo. When I first experienced this issue I was driving through the mountains and couldn't get up the mountain fast enough so I had to pull over to the shoulder with my hazards. The remainder of the climb over the mountains I was going 20-30 mph (while I'm at 5000 RPM or over).
