While driving down the road my car is knocking out of gear, not getting acceleration. Pretty certain its the gear shifter. Also a burning smell comes from my motor.

Press the start button and the car doesn't crank to turn on. Power to all other systems appears fine. I put the car in N then back to P and was able to turn the car on. Change battery and the battery on the key. Still having issues. No-start, no-crank due to gear selector range switch I was informed by Hyundai that my 2012 Sonata was not included in there campaign

Sudden unintentional acceleration on a highway going approximately 45 mph. Saw brake lights on vehicles and started braking. Suddenly, my vehicle sped up, catching up to the vehicle ahead of me. The front of the car was bobbing up and down, but not stopping the vehicle. I do not know how fast I was going when I finally hit the other vehicle. We both got out of our vehicles and to my surprise, there was no damage on either vehicle. (miracle) there was no police or tow trucks called. I was able to get my car home safely. My car will probably be sold by the time you read this. Also, there were no injuries. I was so nervous I did not know what kind of vehicle I hit or if there were other passengers.

The transmission has already been replaced once and now it's starting to do the same things it did before it was replaced... jerking transmission shifts. Took it back to the dealership and they told me the transmission was acting up because the gas engine's battery (not the hybrid battery) was bad and needed to be replaced. The service guy said the battery only showed 10.8 volts which means it's dead. He said a new battery will likely fix the transmission problem because it's an "electronic transmission". I said, "if the battery is bad/dead, why does it start the gas engine with no problem??" so I reluctantly said to replace the battery. Then he tells me the battery is $400... I told him that was way too expensive and I can buy one myself for less than 1/2 their cost. So I took it first to an advanced auto where I asked them to load test the battery before I bought a new one. Their load tester showed the battery as good @ 12.8 volts (not 10.8). Before I left, I had them test it a 2nd time and that test showed $12.57 volts... still good. 2 days later when my wife leaves work, the transmission starts jerking again and a yellow "wrench" icon pops up on the dash. She called me and I had her stop by a different parts store to have another test on the car battery. She stopped at an O'reilly's this time and their tester also showed the battery to be good. So the question is, is the jim hudson Hyundai dealership giving us the runaround because they don't want to fix/replace the transmission again? now we're trying to get the other Hyundai dealership in town to check the car out. Gonna be the last Hyundai we own...

Last year (2016) 2 months after I purchased my 2012 Hyundai Sonata my engine failed. I realized it was due to a recall on my car. I was not notified at time of purchase and car facts did not mention open recall. The dealer refused to pay or be involved in the fixing of the car or the rental. Even though I paid 2000 dollars out of pocket for an extended warranty. The Hyundai company completed the recall fix on my engine and my insurance company (state farm ) got the dealership to cover half the cost of the rental. This year (2017) almost exactly 1 year later I am driving 60 mph down the freeway and my engine fails once again. I had my car towed to the same merced Hyundai dealership hat "fixed" the problem last year. The problem is the fuel tank has metal debri in it from the time hey built the car and over time as it passed through your engine it breaks it down. The "fixed" the problem by replacing my engine block but not replacing he fuel tank so won't the problem just happen again? I am hoping they don't try to make me pay for it this time around. I would like to know my options for this situation and who needs to be held accountable.

Boyfriend's vehicle. Check engine light came on and the code P0087 was noted by the obdii (fuel rail pressure low) mechanic originally stated that this was an "intermittent" problem and the whole system would have to be replaced at + $1200. This didn't make sense to him so he asked to be shown exactly where the problem was located, and what part was causing the problem. The mechanic could not give him an answer. "it's around this area" he replied as he waved across the center of car. He went to another mechanic and another after that. Only consistency has been the lack of know how to fix this problem. In the meantime, his oil is thickening and darkening, and his fuel is not giving him the mileage it should. It seems the only assistance anyone wants to give revolves around replacing the whole system, yet the servicemen themselves admit that they are uncertain that this avenue for repair is necessary. None of them can offer us a repair or replacement of the sensor itself. Finally, one mechanic advised us that under the P0087 error code the following could be causing the engine light to come on: 1. weak fuel pump, clogged filter or screen, restricted fuel supply line 2.faulty fuel pump driver module 3.faulty fuel pressure sensor. Unfortunately, this mechanic is a student and not certified to perform repairs. I verified his opinion thru obdcodes.com but was quickly disillusioned because again, no one is willing to check these causes individually. Finally my boyfriend was told to just buy a can of air spray to blow out any surrounding dust and then just let him 'reset' the check engine light and see how long it stays off. I know that this is wrong and have found a repair guide finally. But, I also now find service bulletin no.: tsb-15-01-010 component(s): Engine NHTSA id number: 10058132 that seems to be about this issue. How do we resolve this problem already?

The contact owns a 2012 Hyundai Sonata. While driving approximately 5 mph, the vehicle accelerated when the brake pedal was depressed. As a result, the vehicle crashed into a pole. The vehicle was towed to the dealer, but the failure was unable to be duplicated or diagnosed. On a separate occasion, the failure recurred and the vehicle sideswiped a tree. There were no injuries in either crash nor were police reports filed. The unintended acceleration recurred sporadically. The manufacturer was notified of the failures. The approximate failure mileage was 53,000. Updated 04/29/16

While sitting still at stop light on a city street with foot on the brake pedal and in drive- the car lurched slightly like it was trying to go forward. The brakes stopped it from moving.it felt a bit like the car shifted to a another gear.the whole event lasted about 2 seconds. Otherwise the car behaved normally. This has happened three to four times since we bought the car new in Dec. 2011. A disturbing event. We would like to know if others have encountered this, and is it dangerous?

Issues with loud rattle noise coming from engine when accelerating over 40 mph.called Hyundai dealer service dept.& made appt to get inspected. Service rep claimed the mechanic heard no noise, so I had to go drive car with mechanic to identify noise. (noise obviously noticeable) after driving car with mechanic he said the cvts needed to be replaced. I took my recall notice for NHTSA # 15V-568. I asked if this was due to metal debris left in engine they said no.they gave me a rental.took 2 weeks for cvts to be replaced. About 8 days later after Hyundai returning car the noise was back. 3 weeks it got worse, called Hyundai dealer, took it back. The service rep. Again claims they dont hear anthing.have to drive my car again to identify noise to mechanic.its very frustrating. There still is no solution to rattle noise, recall or have they inspected my car properly for the car issues I am experiencing & reporting to them. The car stalled on my way to drop it off. Rpms increased but car did not accelerate. Let off gas pedal then tried again serveral times finally the car puttered & proceeded. My daughter was in the car with me so it was a scary situation for the both of us. I told the service rep what just happened. Left my car & they gave me rental.I have experienced loud noise from engine since I bought the car new in December 2011. Was told that the car is supposed to be loud & make the rattle noise bc of eco engine. As the years have gone by the car's performance has worsen. It has stalled several times. I dont feel safe. The car only has 45,000 miles. Ive had several issues battery, steerling wheel, radio, etc..bad experinces. Ive maintained the car with proper oil changes, reported all issues on file with Hyundai service dept.Hyundai needs to take responsibility & fix the problems with their cars & find a remedy to thier engine recall asap. Safety is important.

On August 7, 2015 at approximately 9:30 pm, I was coming back from running an errand with my 16-year old daughter in the car with me. I made a right-hand turn when suddenly, all of the lights on the instrument panel illuminated and the engine stopped. Additionally, I lost all power steering, etc. I was able to maneuver the vehicle to the side of the road immediately, but almost got rear-ended by a pickup truck that was following me. I turned off the car, let it sit for a few minutes, and started it up again. The car seemed fine at that point, and I was able to continue my short drive back to my home (approximately 1.25 miles). When I arrived at home and placed the car in park, the oil pressure light was flickering slightly. I turned the car off and went into the house for the night. The next morning (8/8/15), I checked the oil level in the engine, and noted that it was slightly above the fill line. I added some synthetic oil to the engine, checked the level and noted that it was adequate. I started the engine to go run some errands. The car seemed fine at first, but when I was approximately 5 miles from my home, the oil pressure light began to flicker again while the car was idling (at a stop light, etc.) I called my husband right away, who told me to bring the car home. I noted that the engine had somewhat of a ticking noise while driving it. When I was approximately a quarter-mile from home, the engine started knocking/banging very loudly. I immediately shut the car off, called my husband, and called for a tow truck. I had the car towed to my mechanic's shop. On Tuesday, 8/11/15, my mechanic removed the oil pan and informed me that the bearings were failing, which caused metal shards to clog the oil pump filter, and he also noted that the oil pan was full of shards. This car is a safety hazard and needs to be recalled!!!

First time noticed that the oil pan is leaking at 15,042 miles. Took the car to the dealership and they resealed it under warranty. Started leaking again at 22,566 miles and took it to the dealership. This time they replaced the oil pan and resealed it again under the warranty. I just noticed it that it's leaking again at 30,660 miles. I am really concerned that this brand new car is leaking oil like this. Also, I strongly feel that the fix is not addressing the underlying issue which may be something else. I think Hyundai needs to look at this issue closely and must come up with a permanent solid fix. I have been reading on the Hyundai Sonata forum that many are facing the same problem. I am surprise that there is no recall for this yet. This is my first and last Hyundai.

The car hesitates during start up! I have had it into the shop approx 9 times since we have had the car. This last time (approx 30K miles) they told me it was normal. I am afraid this car is an accident waiting to happen!
