NHTSA Complaint #11427058 — 2014 HYUNDAI SANTA FE

At highway speeds going through the mountains, the engine began to lose power and then began to shake. One or more cylinders began to misfire while climbing a hill with many other cars and trucks in the slower lane to avoid. The engine light was flickering and depending on the position of the accelerator would go on and off. The car began shaking rather violently, but I couldn't pull over so others needed to avoid me. I coasted down a hill and made it off an exit ramp. Then engine had no power at this point and was still shaking. I checked the oil and found it had burned nearly 1 qt. in 100 miles. I noticed nearly all the oil was gone on the prior oil change and thought the mechanic had not put enough in. I now think there is something dangerously wrong with these engines consuming oil. The engine light has been coming on for a while and the dealerships or others I had read the codes normally indicated cylinder 3 contribution. This was never solved as it would come back on after a few months from having it worked on. The dealership still has the car and stated that cylinder 1, 3, & 4 had misfire codes and that 1& 3 plugs were coated in oil. After cleaning the engine and doing compression tests it appears the engine is destroyed. I'm glad the engine didn't lock up and I can only image what would have happened had I been able to continue on that trip and it consumed all its oil while driving. A locked up engine may have resulted in a fire or wreck as the loss of power on a mountain nearly did.
