2018 Hyundai Elantra acceleration complaints
Page 2 of 2: complaints 11 to 13 of 13, newest first, as owners wrote them.
Car has intermittent problem with acceleration. Will go into a fail safe mode, wont accelerate past 40-60 MPH. I have had very close call on multiple accidents due to the fact I am unable to accelerate. My car lost power and could not pick up speed at all. This is a major safety issue and the car dealership will not help me.
Tl* the contact owns a 2018 hyundai elantra. The contact stated that there was a sudden loss of acceleration when the accelerator pedal was applied. The vehicle was taken to the dealer (empire hyundai inc, 428 pleasant st, fall river, ma 02721, (508) 673-7646) more than twice, but they could not replicate and diagnose the failure due to no dtc. In addition, a service technician test drove the vehicle and was unable to duplicate the failure. The manufacturer was notified and indicated that they would provide a follow-up response to determine a solution. The approximate failure mileage was 50. *tt
