On highway 70mp Sonata loses all power towed to Hyundai dealership. 3 days letter knock was to blame an wiring replaced. 15 minutes after picking up Sonata an reaching speeds of 70 again on highway Sonata loses all power again almost causing pileup in rush hour traffic gain Sonata is towed back to dealership. Dealership confirms only parking lot test was done not highway after replacement even knowing the wide spread engine failures / issues Sonata is having an catching fire. This is serious an life threating you lose all control no power no warning !!!! at high speeds. 1/8 Sonata currently at dealership.
At around 80,000 miles car started going down hill. It hesitates to take off from a stopping point. It shakes sometimes when about to accelerate and it doesn't accelerate very fast anymore gets up to about 1800-2000 rpm before it actually picks up speed.
P0010 code and p0011 can hear a metal grinding noise when accelerating also fluctuating rpms. I keep immaculate maintenance and take excellent care of it. Absolutely no idea how but parked car everything was normal, started car next day and rpms shot high and light came on. They reset light and say nothing wrong but this keeps occuring. Highly upset as I have absolutely loved everything about this car until now.
Car decellarates on it ,s on when you try to pass or speed up. Cuts off. Jumps.
Whenever I accelerate on the highway my engine would rev to a high rpm with a delayed reaction in order to get the car accelerated. Also, whenever I slow down my car for a stop light or stop sign, my engine would rev to a high rpm to slow down my car. I asked the Hyundai dealerships, they said the everything is okay, however I can tell right away there's a difference with my 2015 Hyundai Sonata vs my girlfriends 2015 Hyundai Sonata, exactly the same year and model and trim, but the drive is totally different. Also, I can also tell because the mpg on my car is far lower than my girlfriends. And she has a heavy foot on the gas petal. It doesn't make sense. The Hyundai dealership also reset the computer of the car, but no difference.
Car hesitates taking off from stop. Shakes and sometimes is unresponsive for a couple seconds.
1/14/18 upon entering a 4 lane major road from a store parking lot, my 2015 Sonata would not accelerate. I let off and pushed the accelerator pedal, no response though the rpm's were revving. The check engine light came on. I pulled over, shut the car off, and restarted the car. The car seemed to accelerate ok after some initial hesitation. However, the engine light is still on and the car is accelerating up to 11 mph, in drive and reverse, on its own when the brake is released (no use of accelerator pedal). In addition, when in drive, the car lurches forward reaching a speed of about 5 mph as soon as the break is released. I see recalls for these engine issues on 2011-2012 models. Appears issue not resolved with engine recalls showing for mode years 2013-2014, it seems the engine issues are still not resolved for 2015. My car has less than 45,000 miles and has been serviced at the Hyundai dealership I purchased the car new every 3000 miles until my oil change time before last. The next service sticker was for a 5000 mile interval and when I questioned this, I was told the dealership was using a higher performance oil that didn't require changing prior to 5000 miles. I had the next oil change done at about 4000 miles. I am concerned I will be told there is nothing wrong with my car, my engine is going to seize, and I will be stuck with this repair expense.
Car keep cutting off and speed keep dropping.
On multiple occasions (about 10) since April 2017, vehicle has decelerated to very low speeds, e. G. , 10 mph while traveling at 35-40 mph on a city street, which is usually accompanied by engine dying. This was reported to o'brien Hyundai of fort myers, FL on 4/20/17. They were not able to duplicate the problem after test driving for 8 miles. Since April 2017, we have also experienced numerous failed electric switching functions, e. G. , door opener switches while vehicle is stationary. While these have been reported to o'brien, the company has not been able to duplicate the problems. However, both my wife and I have experience the smaller problems on a daily basis, and the more serious problem described above on a weekly basis.
Takata recall. . . . . . I was driving my car and I heard a loud noise, shortly thereafter, the car dashboard said that the car was running hot and it shut down in the middle of traffic. I rolled to a stop and put the car in park. I got out the car and look under the car to see if I saw anything because of the noise, and I didn't see anything. I popped the hood and noticed that the antifreeze level was not low and that the pressure was not tight on the radiator hose. So I could not understand why the car was running hot. I closed the hood and got back into the car and started the car back up because it appeared to have cool down. I drove the car to the nearest parking lot and called a tow truck to take the car to the dealership. Once the dealership look at the car, they noticed that the pulley was not on the alternator, the serpentine belt was at the bottom of the car and that was the reason the car was running hot. They said they have never seen anything like that before. New car with only 66,000 miles on it and the pulley on the alternator is completely off while driving is not safe. In rush hour traffic in the city, is not safe for me and my kids.

On July 12,2016 I was pulling into a parking spot at the bank. My foot was on the brake as I entered the space. My car then seemed to make a loud noise like the engine was revering ups it then shot forward like a rocket. It felt someone had smashed behind me! luckily there were pillars in front of the bank which prevented my car from crashing in the bank. I have found several complaints with the 2015 Hyundai Sonatas doing this however there is no recall. Cost of damage was $9,051. This was an extremely frightening experience!.
