My vehicle is a 2019 Hyundai Elantra. It has the Hyundai Nu 2.0L engine, which has been the subject of recalls for engine failure, stalling, and sudden loss of power. The check engine light came on but not before the majority of the dangerous driving conditions surfaced, meaning I had almost no warning before the issue put my life in danger. My vehicle was not included in the recall even though other models with the same engine had been. I experienced unpredictable stalling, hesitation, and engine failure while driving. On several occasions, the car stalled unexpectedly in traffic, creating a serious safety risk; I nearly was rear-ended multiple times. The vehicle became increasingly unreliable, prompting me to take it to the dealership. The dealership confirmed that the engine failure was consistent with the known Nu 2.0L engine defect. There was metal debris in the oil even though I have kept up with maintaince and oil changes at the regular intervals suggested by Hyundai guidelines. Hyundai covered approximately 90% of the engine replacement under a “good faith” adjustment. Documentation of engine inspection and repair available upon request

My car started hesitating when shifting gears in smart and normal mode smelled like something was burning. Car only drives in sport mode, shifts hard, engine lags, and the check engine light has not come on. This is the second incident with this car. The first time I lost all power to the car and the entire electrical system shut down, when it was towed to the dealership they said nothing was wrong with it. I keep up on all the maintenance.

High beams quit working I. Weather conditions and now high beams don’t work period and have to replace head light do to problem with assembly driver side and passenger side high beams don’t work. Vehicle engine light came on and vehicle started driving rough at times stalling while driving it. Took it to a mechanic after replacing all coils plus spark plugs vehicle still showed engine light on. It also diagnosed sensors and cam shafts, solenoids. After all work performed vehicle engine light was still on and was driving rough at times still stalling on the road. The car would stall constantly with out warning. Sometimes will start up again and sometimes it wont. Then increased oil consumption, progressing to a knocking sound, and the engine seizing and stalling. Also warning light in the instrument panel, knocking noise from the engine, reduced power or hesitation when accelerating, or the smell of burning oil. Engine shut off while driving. Now car won't start at all. Took the car to be looked at they ran all kinds of diagnostic testing, one of which came back showing my engine lost almost all compression. Bought it from dealer car was used as a rental. I am the first real owner. There was a hyndai Elantra recall for engines but I believe my car is not included and I think my car has a 2l engine.

I was driving down a main highway, approaching a busy intersection preparing to turn left... I had a green light without a green arrow and had quite a bit of distance/time between myself and any approaching vehicle so I went ahead and proceeded. Just as I entered the intersection, all of the sudden my car stopped responding to my pressing on the gas pedal. The motor was very loud and dry sounding, and the RPM gauge was running abnormally high but the car itself, was barely moving. I continued trying to give it gas, even checked to see if something had knocked it out of gear (that was NOT the case)! Cross-traffic began to approach the intersection so I really started to work on the gas pedal, pumping it and when that failed, I mashed the gas all the way to the floor and finally just before I was about to be hit the car down the pedal and finally the car began to move!! It has been doing some hesitating for a while now but it barely made it out of the intersection this time and that was terrifying!! I have it in the shop now waiting to see what the problem is but this needs reporting. I do everything I'm supposed to with maintaining my car... oil changes, spark plugs, fluid checks and it has less than 50,000 miles so that shouldn't have happened!
