I leased my 2017 Hyundai Elantra new in July 2016 and later purchased it. As of September 2026, it has approximately 77,000 miles. I am reporting two unresolved safety concerns despite repeated repairs and more than five months of seeking assistance from Hyundai. Multiple ignition coils have failed during my ownership. Most recently, I paid approximately $400 for service after another coil failure. Although the check engine light is no longer illuminated, the vehicle continues to struggle to accelerate and abruptly jerks or âburps,â particularly around 30 mph. At times, I must press the accelerator nearly to the floor to gain enough speed to safely merge onto the highway. I commute…

I bought my 2017 Hyundai Elantra SE earlier this year with about 119,000 miles. It had good maintenance records when I bought it, and it now has about 128,000 miles. Since buying it, I've had two oil changes done along with new spark plugs, coils, front brake pads, and tires. About two days before the engine failed, I noticed the car had suddenly burned through a significant amount of oil. There was no visible oil leak. The car stopped running, so I had it towed instead of continuing to drive it. Oil was added, and afterward it started and seemed to be running fine.The next day, I was driving approximately 70 mph on the interstate when the car suddenly lost acceleration and warning lights…

All four rear/side door latch mechanisms have exhibited intermittent failure to release the door from the interior and/or exterior handle. Repeated operation or increased force can sometimes cause the door to release. This creates a potential safety hazard because an occupant may be unable to exit the vehicle through an affected door during an emergency. The manufacturer has previously issued an extended warranty/TSB addressing this latch failure, but the vehicle is now beyond the 10-year extension period.
