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.

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.

I have a 2015 Hyundai Sonata with 24K miles. The check engine light came on and was flashing as I pulled into a parking lot for my daughter to pickup her car. The garage owner said to pull in my car. The diagnostic read out was P2600 obs-ll. Upon researching it the code said, coolant pump "a" control circuit?open. They provided me with the print out. They said try to drive it. I did & drove maybe 300 feet & it would not accelralte above 15 mph. I turned around took it back to the garage's lot. The next day I called Hyundai roadside assist to have it towed to superior Hyundai South, where I purchased the car.this occurred Thursday January 17th. The car is still at superior Hyundai waiting word from Hyundai motors. Dave the service manager said it either needs a wire harness or an engine. Not sure the relationship. Seems to me they should put on the wire harness, if that doesn't fix it replace the engine.

Cylinder 4 went bad at 113,000 miles. Out of warranty, Hyundai did decide to cover the cost of a new engine. This happened on 8-10-18 and the vehicle has still not been repaired. Hyundai has stated that the engine is on back order and could be the 1st week of January 2019 and possibly later before the engine is available. I have heard from the dealer that there are close to 10,000 Hyundai 2.0T engines that are needing replaced for the same issue. So far 4 months of car payments and car insurance being paid on a vehicle that cannot be driven.

On Friday October 12. 2018, I was driving on the 78 high East bound and was about to pass another car. As my car was accelerated, the car engine lost power. The engine check light came on. My car was decelerated. I was lucky because the traffic on the freeway was light. I was able to move the car slowly to the emergency parking area and stop the car. I have a car computer diagnostic device and hooked it to the car computer. The device read an error code P1326_ glow relay stuck on the car was towed to the nearest Hyundai dealer. So far the dealer service department has not told me what wrong with my car and how they fix my car..

I took my car to priorty Hyundai because it wouldn't start. They said it was a issue and then priorty Hyundai fixed it and let me drive it. 3 weeks later it did not start. They say they fixed it but now they are telling me to tow it to them so they can check it. They say a recall has been issued. And I have to wait 5 days until the check it. I am missing work. They said it was already fixed. Before it stop working I took a 5 he trip. The car was defected and they let me drive it. It stopped once when I was in the highway coming back luckily traffic went around me until it started and I was able to get home. Now it doesn't start.
