My car has been hesitating and cuts off while driving. Whether I go 25 miles per hour or 70 my car continues to hesitate. When it hesitates I can rev the car with the accelerator to the floor but my car wont engage. I have to take my foot off the accelerator and hope my car re-engages or my engine will cut off and I have to restart it. I have had my car in the shop 5 times. 0N 11/22 orlando Hyundai replaced low pressure fuel pump. On 12/18 per the tech line says high resistance injector harness and fuel rail high pressure sensor needed replacing. On 12/23 the PCM has intermittent internal open circuit. The PCM was replaced and fuel line. 1/12-1/23/18 replace control harness and crank sensor. I placed my car into lemon law. I received a letter from Hyundai to bring my car in today 2/22 I was asked if I had any other problems and told them my car hesitated at odometer reading 10022 miles they check my car and was told my car has no issues found. John mc my service advisor drove my car with me in it he says he knows there is a problem and it hesitated on him and say but we don't know how to fix it. He said today we didn't recreate the issue so we believe your car is fixed. This car is a safety issue. This is the same problem I had with a 2015 Sonata. I traded that in for a elantra that was way to small for me and I traded for this 2017 Sonata. This car is a major safety issue. Not sure what to do. Hyundai needs to find out what wrong with this car so when this problem arises to another Hyundai a solution can be found. Just give me a new Sonata and I would be happy, I bought my car with 6 miles on it do the right thing Hyundai. It's awful scary at 70 mph to have this hesitation begin. What does it take for Hyundai to do something (have an accident?)

On Saturday 9/16/17 I was at a stop light sitting still when my car stalled and went dead. I looked at the dashboard and saw the engine light was on. The brake was frozen and before I could restart the car it rolled into the vehicle in front of me. There no damage to her Jeep. However my car hit the spare tire and rack on the back of her trunk, causing damage to the hood of my car, the grill and lower bumper. We did not exchange information, as she did not have damage to her car, so she left the scene. I drove the car home (2 miles from my house) and called the dealership. They told me to bring the car in. I brought it in the same day. Raymond, the service agent came outside to survey the damage and I told him what happened. He went to talk to the service manager and later came out and said they will take the car and put it on the machine to get a diagnostic reading to see why the car stalled. They gave me a loaner car and I left. On Monday, 9/19/17, I returned to the dealership after I got off work and was told by raymond that they could not find anything wrong thus far. He said he wanted to keep the car another day or two to take it for a drive and try to see if it would stall again. I agreed and asked raymond to also check the fuel injectors, fuel pump, fuel regulator, as my friend who is a car mechanic suggested to me that this can cause a car to stall also. He said okay. On today, Wednesday 9/21/17, raymond called me and said they took the car out for a drive and it did not stall, nor could they get a reading that anything was wrong when they put it on the machine. He said he could not understand why the car would stall. I asked for a diagnostic report and he said he could only give me a copy of the service ticket. I am afraid that this car could stall again and what if it happens while driving -- it could be much worst damage and bodily harm. Please help!

While driving to work this morning, brand new Hyundai Sonata with 980 miles shut down and turned itself off when I made a stop at a red light. I was lucky I wasn't moving fast on a highway when it happened and didn't get into an accident, but it's totally unacceptable for a brand new car to shut down like this.

First extended drive of new car, check engine light came on. Took it to dealer for service, was told I had "bad fuel" that they tested a sample and found E85 (ethanol) in it, which is not covered by Hyundai new car warranty for plug-in hybrid electric vehicles. I paid $828 to have fuel drained and replaced, fuel injection cleaning, and decarbonizing and throttle body cleaning. Check engine light went away, but turned back on a few days later. Again took it to dealer but they were unable to get it to turn on after I left it, so returned the car to me, no charge. I had only added 87 octane gasoline (per owner's manual recommendation) to my car 3 times prior to the first check engine light episode, at stations that did not sell E85. During subsequent conversation with Hyundai rep, was told maybe water was in gas. But engine ran fine and I drove 100 miles after last gas fillup so I suspect there may be a problem with the emissions sensor that manifests as check engine light with random (inaccurate) diagnostic code. I got this car in Chicago, but Illinois is not a low emissions vehicle state, so the plug-in hybrid is not allocated to Hyundai dealers in Illinois. The Sonata hybrid, however, is sold here but I don't know if it shares the same engine/emissions sensing system as my plug-in hybrid electric. Dealer service did check for obvious things: Gas cap, resetting the engine diagnostic chip. I understand the 2016 model phev is substantially the same as my 2017 model, in case similar check engine light issue happened with 2016 cars.
