Around 25000 miles, after start, strong engine vibration with no power - about to stall. Dealer changed variable charge motor after 5 occurrence of similar situation. After few months at 29000 miles, 2015 Sonata SE (2.4L 4 cylinder engine) lost power and stalled in the middle of city street, while driving. Could have caused big accident if I was on highway. Car was unable to restart. Towed to dealer and replaced accelerator position sensor. Could be related to issue with 2011-2014 Sonata engine recall since my 2015 Sonata uses almost same theta-II engine.

While coming to a red light car engine revved very high and I had a hard time braking. At red light I put car into neutral but the engine still was revving high. I put the car into park and when the light turned green I put it into drive and drove it back home less than half a mile away.

I am experiencing problems with the steering. The steering has dead spots and feels extremely loose, it is very stressful keeping the car strait on the highway as it is all over the road. The steering light comes on but the dealers always tell me "we can't find any codes". there was a loud what he thought was an "electrical" sound in the front end while turning the steering wheel as the service manager at tameron Hyundai put it. Instead of checking the steering they put struts on it, which has made the problem 1000X worse now the alignment is off which they can't seem to fix and with the steering problems makes it nearly impossible to drive. Whenever it rains the steering light comes on and the steering wheel either stops responding or becomes hard to steer. I put new tires on it less than a year ago that have less than 10,000 miles on them and have rotated them twice at 5,000 miles the alignment is so bad that one tire is now bald! every time I go to a dealer they refuse to help. I'm putting this here in case I die in this car! also the engine hesitates and shakes violently when starting. The shaking is when it ideals, but on the interstate when you press the gas it "pulses" and hesitate while accelerating (I hardly get a chance to test to see how bad the hesitation is because the steering is so lose) I am now finding out the 2015 Sonata engine is effected by the massive defect they have had in 2011- 2014 models but are not making it publicly known. One would think with all the steering and engine problems Hyundai has had in the past Sonata's they would take this serious. All they do is blame customers, if you call their customer support line they will tell you they closed your case in less than a day without looking at the car. I hope the government gets this company under control for consumers sake and safety sake.

My vehicle is stalling out while driving it I took it to the Hyundai dealership and they said they could not find anything wrong with my car. This has happened three (3) times two of which my 11year old child was a passenger in my car. It happens at random sometimes the car starts shaking then seems to loose power or die down then picks back up or the worst stalls completely! no one can tell me what's wrong or help me the Hyundai dealership tells me that until something happens or the computer reads something they can't help me! I have witnesses who have also experienced it while driving my car aside from the three times I have experienced it myself.

Engine has approximately 60,000 miles and burns between half to one quart of oil every 1,000 miles. Hyundai dealer performed an "oil consumption test" where they recorded oil level after 1,000 miles three times. After the first 1K miles it was down about half a quart of oil, same on second 1K miles, and about 1 quart on third 1K miles. Hyundai advised this is normal oil consumption and would not investigate further unless average use was more than 1 quart after 1K miles. The suggested oil change interval from Hyundai is 7,500 miles. At the rate of oil consumption the vehicle would be out of oil before the recommended service interval for oil changes.

I bought my 2015 Hyundai Sonata brand new. Today (Mar 22), I made a right turn to a ramp into my company site. Speed was about 10 to 15 mph. All the sudden, I heard a laud engine revving sound. I have to let go my gas pedal, waited couple seconds and then slowly stepped on the gas pedal to move the car. It almost like the gear box was not engaging all the sudden and the car speed stalled. This would have been really dangerous when driving on a highway. The government should investigate the similar cases and make the manufacturer for a repair/recall.

My 2015 Hyundai Sonata was purchased brand new, and have had multiple power/acceleration issues; however, the most recent happened on March 19, 2019. While driving on a street (evening time) with the speed limit of 45, my car started to sputter/jerk back and forth, abruptly bringing my car to a speed limit of under 15 mphs. I tried to accelerate, but the gas paddle was unresponsive. This a major hazard and extremely dangerous. This is a known issue, and Hyundai corporate office is aware (I called after the first incident), and is not doing anything to rectify the issue. NHTSA need to make the manufacturer accountable, by reason of the numerous complaints about the same issue. I was close to being rear-ended, and if nothing is rectified, it will cause an owner to be severely injured.

While driving on a busy street, on March 19, 2019, my 2015 Hyundai Sonata begin to sputter and not accelerate over 10-15 mph. This is not the first time that I have had this issue. The corporate office is aware of this issue. I was told that it was electrical and that it was my throttle body. I purchased that car new and now it has a little over 74,000 miles on it.

My 2015 Hyundai Sonata limited suddenly lost all power while driving 60mph on they highway during morning rush hour nearly causing a major accident. This seems to be significant problem after looking up this issue with these cars and furious Hyundai has not sent out notices of such a serious safety issue. I don't have confidence in this car to travel with our children.

Received a Sonata's engine control unit letter, stating a product improvement campaign has been issued on my car, on excessive connecting rod bearing wear in the engine. I have a severe knocking in my engine, when moving, especially when excelling up a hill, and it stated this can cause severe engine damage including engine failure. Told service man and he stated if it is this it could take one-three weeks for repair. Why isn't this a recall. States for this VIN# -8 recalls, but doesn't list them"? how do I find this out"

Took vehicle for a safety recall on Feb 22, 2019. After leaving the dealership the engine stalled on a busy highway. Narrowly escaped getting into an accident/ crash. Vehicle is back at dealership and they are trying to figure out the problem. I browsed the internet and saw that there are several similar complaints of the engine stalling. The main issue I have is that no one at the dealership informed me of this problem. Will it take crashes and people dying before a recall is orderd on this known problem.
