This is our daughter's car. Yesterday (Nov 1) her car stalled, with the warning "hybrid system warning! safely stop and do not drive". this time she was parked in a parking lot and the warning message came on when she tried to start the vehicle. This is not the first time it's happened. On previous occasions the dealer's technicians did not even record anything in her maintenance records. She understands this is not an unusual problem, with many Hyundai hybrid owners of that same 2015 model year, as well as other years, reporting similar problems. Is this something that is being looked into? the dealer personnel just sort of dismiss this as no big deal.

While driving on a busy four lane I entered a turn lane to cross traffic. Immediately after I engaged the accelerator the vehicle lost all power and steering, with a alarm stating 'hybrid system warning-do not drive'. one vehicle narrowly missed hitting my car, (as it completely lost all power and steering and left me stuck in the middle of on coming traffic). Researching today I see this is common between 2012-2016 especially. This is a very dangerous situation that was narrowly avoided.

While driving on a major highway with a 55 mph speed limit, the check engine light came on and the car hesitated and was difficult to maintain the speed limit. I took the car to and auto parts store that has a code reader and saw the manifold runner control was indicating a fault. The code, P200A is described in a Hyundai technical service report for 2015 - 2016 Sonatas however after taking the car into new port richey Hyundai I was told that the service bulletin didn't apply to my vehicle. It is a danger to drive with the control unit failing and may at any time cause the car to decellarate.

My valves have been rattling upon excelleration or climbing a hill. I took it to Hyundai to get a diagnostic. While waiting the sales buzzards started circling. After finally breaking away from them I went to get results of my test. The technichan told me I needed a new motor and good thing I was trading it in. I told him I wasnt trading it in and then he said I need to do a few more tests. Of course when he came back it was a different story. I needed plugs. My car still has same problem. They are waiting and hoping my warranty runs out in 10000 more miles. Why isnt there a recall on this motor"????"

Vehicle is going through engine oil very quickly. No evidence of a leak, no evidence of burning. Oil light does not illuminate when oil is low. When I checked this morning, my oil level didn't register on the dipstick - but no warning light came on. I was only 100 miles over my scheduled oil change. Last checked 2 weeks ago and was fine.
