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 federal safety agency 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.
