Two issues: Severe problem - when driving at a rate of approximately 35mph today on a major city thoroughfare, our 2017 Hyundai Santa Fe 2.0T ultimate suffered a sudden and complete loss of power (engine and all electrical systems including lighting). After coming to a stop, the vehicle was stranded in place until it was able to start up again many minutes later. Fortunately no one was physically harmed as the individual driving behind our vehicle was observant enough to identify the issue (despite a lack of brake lights or hazards) and stop in time. No visible engine light or fault code was triggered. Less severe problem: On a regular basis, the vehicle suffers abrupt and sustained loss of power in merging situations (especially when turning on city streets from a stop). This seems to be from an overactive or otherwise ineffective traction control system/programming. Despite even planning for the possible loss of power, this has still resulted in a number of "near miss" situations. A warranty visit has been scheduled for these issue and we will gladly provide the results and/or other updates upon request. We are, however, seriously considering selling the vehicle at a loss due to these two issues.

In the affected vehicle, the wires in the can wiring harness assembly and airbag wiring harness assembly may be damaged by the passenger seat's height adjuster mechanism. A metal 3rd party power inverter was positioned underneath the passenger seat. Prior seat adjustments caused the sheath around the harnesses to become bare, exposing the electrical wiring. The metal power inverter become lodged against the wiring causing a short in the wiring and causing the entire vehicle's electrical system to fail. The epb (electronic parking break) became engaged and it was impossible to drive the vehicle. Although acknowledge that the 3rd party power inverter was under the seat, the vehicle had been driven 4 times with it under it, totaling less than 800 miles. It is not known how long it would take for that box to rub against the sheath on the harness and bare the wiring, therefore it is suspected that the power seat adjuster caused the wires to become bare and that recall #141 safety campaign #16V145000 may not have been properly resolved. We believe the seat adjuster caused the wires to become bare, prior to the inverter being placed under the seat. The inverter was positioned such that it wasn't making contact with the bare wire, until the seat was adjusted on 7/2/2017. The car was not driven on 7/3/2016. The incident occurred on 7/4/216 as the vehicle was driven across railroad tracks. It is believed the inverter was then jarred against the bare wire, causing the short. The dealership has not validated this; they are suggesting it was the inverter that caused the wires to become bare. Our opinion is that the inverter was not there long enough to cause that wiring to become bare. It wasn't until I discovered this previous recall that everything started to make sense. It is a $5,300 repair because the other wires involved that are bare are for the airbags.

I bought the vehicle on 5/7/16. On 6/2/16 I was driving on highway 395 when I noticed smoke coming out of the engine compartment. The car started losing power and eventually died. When I got it pulled over to the side of the road I noticed flames coming out from the front of the engine. I grabbed what I could and got out of the car. Within 5 min the front of the car was engulfed in flames. I had approximately 675 miles on it. I have contacted Hyundai but they have not responded to me. I ordered a copy of the police report but have not received it yet. I have pictures that I have attached. I am concerned about this happening to other people. Thankfully I didn't have grandkids in the car, I'm not sure I would have been able to get them out.
