2016 Hyundai Elantra GT engine problems

“Bought a 2016 Elantra in 2020 with 44,000 miles on it and a clean repair/ maintenance history. Let me preface the rest of this by saying I am an ASE certified mechanic of 15 years who has been in the industry even longer. The first major issues I incurred with the vehicle happened approximately one year after purchase. The lifters started tapping and not long afterwards (about a week) I had a total engine failure on my hands. I was almost killed by a passing semi truck that was merging on to the interstate but was luckily able to avoid it and get the car on the side of the interstate where I had it towed to Ralph Sellers Hyundai in Baton Rouge Louisiana. Long story short , even though the second owner is entitled to a 5 year, 60,000 mile warranty, they made me pay for a new engine. Here we are only 19,000 miles later and the same issue is occurring; except this time due to the stress the failing engine is putting on the torque converter the transmission is now failing to do its job properly. I have been back to the dealership but they offered no help except lies (they told me my high pressure fuel pump was bad, this model doesn't even have one!!!!!) I fully…”

“While driving the car will stall regardless of speed or distance. Hyundai dealership states that this is due to a drop in oil pressure due to a faulty oil pump. I replaced this pump 18 months ago on 6/7/2023 with 87K miles. The car is displaying the same issue again on this date (1/14/2025) with 104K miles, and I took it to the Hyundai dealership, and they state that it is experiencing the same oil pump failure. The service department at the dealership stated that this is a known issue with these Hyundai Elantras, and this would be the third replacement of this oil pump. It was replaced once by the original owner under warranty. My contention is that this is a safety issue, because when the oil pressure dips the engine shuts off, and we lose all power to the car. This is a danger to us if this happens while driving the car.”

“I am writing to formally request an urgent investigation into a potential recall for my vehicle, a 2016 Hyundai Elantra GT. I purchased this vehicle in 2017 and completed my payments in March 2023. However, in late July, I experienced a catastrophic failure that has rendered my vehicle inoperable. While driving home from work, I suddenly experienced a complete loss of power. My car slowed down significantly, forcing me to pull over to the side of the road. Once I came to a stop, the engine failed to restart, despite the dashboard lights and radio functioning normally. It has now been over two months since my vehicle has been non-operational. After taking it to a certified repair shop for diagnosis, I was informed that the engine is seized. The estimated cost for repairs exceeds $13,000, which is financially unfeasible for me. This situation not only poses a significant financial burden but also raises serious safety concerns. A sudden engine seizure while driving can lead to dangerous situations, potentially endangering both the driver and other road users. Given the severity of this issue and its implications, I urge the NHTSA to investigate the possibility of…”

“I hear a lot of sounds from the engine of my 2016 Elantra that’s only 96600 miles. It sometimes pulls back even though I step on the gas, and when the car is not moving it shakes a lot, though there is no problem according to my mechanic.”

“This car is consuming oil to the degree that it is empty 1,000 miles after an oil change. The engine has stalled out on the highway twice, and once on a back road. It will not accelerate properly, and won’t go over 40 mph. I had the catalytic converter replaced less than a year ago, and I am experiencing these issues all over again.”

“The contact owns a 2016 Hyundai Elantra. The contact stated while driving at an undisclosed speed, the RPM fell to ZERO(0) and the vehicle hesitated while accelerating. The check engine warning light was illuminated. The contact was able to drive to the destination. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.”
