2012 kia serento 2/25/2017& kia had a "anti-corrosion"recall and we had it serviced at mike smith kia in paducah,ky-4/14/17,we will call this document1. Then we we received major engine recall in September 20,2017 about 2012 kia serento's stalling,document 2. We took the vehicle to wyatt johnson kia of TN. October 7,2017 & we were told if it did not pass their tests they would replace the engine. Ok,well they said it passed,and changed the oil,&supposedly put an "mil" sensor and"mil" dash light to detect oncoming engine failure and send the car into what they call a 'limp" mode. Which is not documented on document #3 which to our surprise it passed because it had been making an knocking sound and experiencing some attempt's of the vehicle stalling. Yes after the oil change ran some what smoother,but still every now and then we would get an occasional throttle spike,or an attempt to stall. Got an recall to do a logicupgrade,& took it immediately to wyatt j. Kia Dec. 12,2018,diagn.

Vehicle suffers catastrophic high pressure fuel pump failure on highway resulting in loss of power. Dealership replaced part. This is a high pressure direct injection engine. Engine has suffered extreme noise, vibration, and harshness issues since new. Sudden loss of power at highway speeds is potentially life threatening.
