I have a 2014 Hyundai Santa Fe Sport that is 5 months old with 4000 miles. The engine is intermittently and randomly non-responsive at speed under 40 mph. This has been in for service 3 times, soon to be 4. Computer diagnoses no problems and the technicians cannot replicate the issue. This fault is dangerous since you do not know when the issue will occur. Two very close calls on accidents. Begin to compile records for lemon law arbitration.

Hyundai has similar complaints with its 2012 model but I have no way to know which engine is in this car. Maybe a 2012 engine was slipped in? Any other similar complaints and potential solutions. I have a love/hate relationship with this car because of the seemingly unsolvable problem.
