2016 Hyundai Elantra

Vehicle stalls while driving which is very dangerous. All dashboard lights go on prior to stalling. No engine light is on. Knocking sound coming from engine. Dealer states engine needs to be replaced. Car has been serviced regularly despite that Hyundai denies engine replacement. The knocking sound that engine does is common between this model and year but mysteriously there has not been engine recalls.

I received confirmation from my local Hyundai dealership that my 2016 Hyundai Elantra GT is consuming over 1.8 quarts of oil every 1000 miles. The mileage is currently 70k miles. This is not the result of lack of maintenance or neglect but because of Hyundais engine design. I was told by the local dealership that I would need a total engine re build. This was the only option to fix the issue 100%. I was told that if the issue is not fixed it will result in engine failure. Hyundai is not recalling their engines or acknowledging the inherent danger this will cause. I am at my engines will if I cannot afford this repair because Hyundai won’t honor the Powertrain warranty.

While driving on the freeway at normal highway speed, the vehicle experienced a sudden and catastrophic engine failure. The engine immediately lost power, and the vehicle shut down within seconds. There was no prior warning or opportunity to take corrective action. The vehicle became completely disabled and could not be driven. This occurred late at night with limited traffic, and I was LUCKY to be near a freeway exit. I was able to coast toward the exit, but the engine seized fully, resulting in total loss of propulsion and blocking the freeway exit ramp. Law enforcement had to assist due to the disabled vehicle creating a traffic obstruction and safety hazard. A tow truck was required to remove the vehicle because it could not be restarted or moved. Under normal traffic conditions, this sudden loss of engine power at freeway speed could have resulted in a SERIOUS, potentially FATAL COLLISION. The outcome depended on luck, timing, and location rather than any safety system functioning as intended. The engine was later diagnosed by an authorized Hyundai dealership as seized due to internal failure. Hyundai denied warranty coverage because a software safety campaign had not been completed prior to the failure, even though the failure occurred suddenly and without warning, leaving no opportunity to complete the campaign. However, at the time of the failure, the NHTSA recall lookup tool showed ZERO unrepaired recalls associated with this vehicle’s VIN. The campaign referenced by Hyundai is intended only to detect certain engine conditions and does not repair engine defects. In this case, the engine failed before any detection or warning could occur. The vehicle had just been refueled and was equipped with four brand-new tires, confirming it was being operated normally. This incident involved an unexpected and complete loss of engine power at freeway speed due to an apparent engine defect, presenting a SERIOUS SAFETY RISK to the driver and other motorists.

My fuel pump comes up and my check engine light saying that it needs to be replaced when I fill up my car it automatically resets my mileage for AAA and trippy and it will tell me that I have no gas even though I just filled up or it will say I’m full when I know I’m empty so it’s not reliable. It comes and goes. And then for an electrical issue my Car will randomly stop working and then like come back up and it was underneath the positive plug. there is a clip that someone had to extend because it was too short and causing electrical surges so it’s still a problem if I go over a bump it gets loose so that clip under the positive terminal I believe is loose and makes my car shut off in the middle of driving at once and then it came right back on

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 intend to sue Hyundai of America unless some appeasement can be made. Do not EVER buy a hyundai, they are trash cars made to look nicer than they are. Additional details will reflect most recent incident with engine/transmission.

Bought the car a yr ago and transmission started slipping and stalling sometimes even engine shutting off while driving at higher speeds unable to steer and when pulling into traffic is on interstate almost got hit because I could not speed up it's also using double the fuel while driving longer distances I tried to use my warranty 2x before my warranty was up but both neither time did Hyundai in Owensboro check what I booked the appt for. First one was booked to check transmission and power issue then called the day before and added oil change. When I arrived the tech retyped my order and changed the oil. Brought my keys I asked about the power/transmission issues and was told they didn't know to check that but at that point there was no time and had to reschedule... So I did. Waited almost 2 months booked appt for transmission / power issue and also check the fuel usage. Finish the service call quoting me over $1300 to fix the fuel issue because no one could find my warranty eventhough I had my original paperwork showing who warranty was with and also the acct number for the warranty. When I asked about transmission or power issue I was told there was no one to check that and I had to rebook but this time it was going to be 8 weeks and by then my warranty had expired. I feel like Hyundai did this on purpose because they are in cahoots with the lot I bought the car from. Now my car is getting worse and worse and scared to even drive the car im overpaying for. This was my first Hyundai and more than likely will forever be my last because the car I got was a lemon it seems, the customer service was worthless and the service even worse. I'm reporting to BBB and everywhere I can.

For the past three years I have had to add oil to my car proir to the 3000 mile mark that is recommended. As of the past year, I have had to add oil every 1000 miles. I have had several oil changer businesses tell me that they see this issue all the time with Hyundai vehicles. My car is used to get me to work, doctor appointments, children to school/appointments, grocery store. I live seven minutes from my work. I live three minutes away from the store I grocery shop at. And two minutes from my children's school. I am now starting to hear noises in the engine and I'm fearful this has caused further damage to my car. If I had been made aware of this persistent issue at the time of purchase, I would not have chosen this vehicle. The car never indicates that I'm low on oil. If it runs low prior to the 1000 mile mark it makes an awful rattling noise. My car has been taken into the Hyundai dealership where I live and the issue hasn't been fixed, because they can't fix it. I am very surprised there has not been a recall of these vehicles for this reason.

Component or System that Failed or Malfunctioned: Engine or other I was driving my 2016 Hyundai Elantra in Kissimmee, FL, 34746 when the engine suddenly lost power and the car stalled out. The rpms dropped to 0, and the car could not be restarted. I was able to coast to the side of the road, but I was nearly hit by oncoming traffic. After several minutes on the side of the road, I was able to restart the vehicle to arrive safely home. The vehicle also shuts off at stop lights, drive-through, or idle. How was your safety or the safety of others put at risk? The loss of power while driving could have caused a serious accident. If I had been in the middle of the road or if there had been more traffic, I could have been hit by another vehicle. Has the problem been reproduced or confirmed by a dealer or independent service center? No, I have not yet taken the car to a dealer or independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle or component has not been inspected by anyone other than myself. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were no warning lamps, messages or other symptoms of the problem prior to the failure. The check engine light seems to come and go. I am requesting that the National Highway Traffic Safety Administration (NHTSA) investigate this safety problem. I am also requesting that Hyundai Motor America recall all 2016 Hyundai Elantras that may be affected by this problem. Thank you for your time and attention to this matter.

Brake and fuel lines corroded due to failure of manufacture to coat lines completely. Lost brakes completely without warning. Confirmed by Hoffman and Burnham auto services. Also contacted Garvey Hyundai who stayed this is a problem with these vehicles. Contacted Hyundai customer service as there is a Recall issued in Canada for this problem. Hyundai stated no foreseeable recall in the U.S. Lost of brakes could be deathly, not to mention high risk of fire and death if fuel lines corroded thru
