Open the full vehicle complaint log (all categories)High pressure fuel pump defective. Code p016b. Dealer replaced high pressure pump, gasket, bolt. Sonata has 43265 miles and 80 months.
Complete loss of power. Car shut down at freeway speeds. Dealership runs codes and they cannot find out what specifically is causing issue. Issue cannot be replicated as it only happens a few times a year and has existed since shortly after purchase of the car brand new. There is articles all over the internet people having similar experiences. This car is NOT safe. Hyundai does not communicate hybrid system codes through their telematics system so there is no paper trail. The car also clears the codes out after 3 reboots following the check hybrid system codes. Dealer has reported car shut down due to voltage issues-not able to determine the reason since after reboot the car drives normally.
I work from home so I don't travel that much. A few months ago, my car was jerking when trying to accelerate. The engine light was flashing on and off. I took it on to the dealership and was told it was a computer update causing the problem. After leaving, the car was doing better, but not completely right as it was prior to the issue. I returned back to the dealership later to explain what else was going on. The car still Jenks on acceleration, but not as forceful. I was then told it is possibly my intake manifold and spark plugs. I plan to take my car back for the spark plugs, but I'm curious about the intake manifold. Either way, this is an issue for when I'm trying to accelerate after a stop and I have a long delay. It also does this on an incline. My car doesn't want to climb on an incline.
MY 2017 SONATA HAS STALLED WHILE IDLING IN DRIVE. THE CAR COMPLETELY STOPPED AT A RED LIGHT; RPMS DROPPED AND IT STOPPED. PRIOR TO THIS HAPPENING, I HAD COMPLAINED TO MY LOCAL DEALER THAT WHEN IDLING, IT HAS DROPPED IN RPMS AND FELT LIKE IT WANTED TO CUT OFF BUT DID NOT...UNTIL TODAY. AT THAT VISIT, I HAD THE FUEL SYSTEM SERVICED, AS THEY THOUGHT THAT MAYBE THIS WOULD HELP. THAT WAS APPROXIMATELY 2 WEEKS AGO AND NOW IT HAS COMPLETELY STOPPED AT A LIGHT. I AM TAKING THE CAR BACK IN AS I AM NOT CERTAIN WHAT ELSE IT COULD BE...MAYBE MASS FLOW SENSOR? I HAVE SEEN WHERE THE 2018 SONATA HAD A RECALL REGARDING HESITATION/STALLING ISSUES AND NOW I AM WONDERING IF THE 2017 HAS ISSUES AS WELL. I AM AFRAID TO DRIVE IT IN HEAVY TRAFFIC AS NOW IT MAY CUT OFF ON ME AND NOT START UP AGAIN.
