Selected complaints filed with NHTSA by 2017 Hyundai Elantra owners, lightly cleaned up (personal details are redacted by NHTSA).
When driving at night, sometimes the headlights and taillights will shut off leaving the car totally in the dark. This is a SEVERE SAFETY ISSUE as you can no longer see the road and other cars cannot see you. The problem appears to possibly be associated with the light switch, as you can jiggle it and get the lights back on. Also related to this problem of the lights shutting off is the fact that occasionally the lights will come on long after the car has been parked in the garage, which tends to drain the battery. After experiencing this problem, I checked the internet and found numerous other cases of Hyundai Elantra owners reporting the exact same symptoms, so it seems to be a somewhat generic problem. Hyundai's service department has been unable to isolate the problem on my car. The problem happens randomly and is infrequent but serious when it happens. …

I was driving on the highway, operating vehicle at posted speed limit, traveling about 70mph when vehicle experienced complete power loss for a short duration of time. All electrical off, loss of braking, loss of power steering. Power subsequently returned and vehicle resumed normal operation. This is not the first time this has occurred, but this episode has me concerned since I was driving on the highway this time. I understand that Hyundai has other vehicles experiencing engine problems, not sure if my vehicle is may be experiencing a similar engine part failure.
Hi, Over the course of the 8 years I have owned this vehicle. The brake lights have needed to be replaced multiple times on multiple areas. This is a common issue that there's entirely Facebook and Reddit pages dedicated to because of the known faulty harness issues. It is an incredibly expensive repair and these parts should be recalled as they are a known issue. My service guys know it. Every Hyundai owner knows it. And even random Facebook/redditors know it.
Receiving intermittent warnings to check Automatic Emergency Braking System, Lane Departure Warning System, and Automatic High Beam Light System. All three warnings occur together and happen intermittently while driving. Problem may or not begin when first start driving. The problem will also seem to rectify itself after a period of time then begin to cycle again several minutes or hours later. Will occur at any speed or while idling.
My car has been stalling shortly after purchasing when slowing down and turning. Then it started stalling on the freeway which is a safety big time issue multiple times. Dealership spoke of maintenance they said it needed. They changed a part and parts on my car has been changed multiple times it doesn't make since.
After driving the vehicle at night and turning the engine off certain exterior lighting components would not shut off. Turn signals and reverse lights and brake lamps we stuck in a static on position even when not being activate by turn signal switch or brake pedal being depressed
My car was parked and all of a sudden I noticed the headlights and tail lights turned on. There was an incident where I live that the fire alarm went off in the apartment building and I just happened to be standing outside and my car's exterior lights turned on by themselves. I had my key and I tried to turn off the car remotely, but the lights would not shut off. I had to go to my car, turn it on, and then shut it off. The same thing happened again the next day about the same time around 11 p.m. I did the same thing. Turned the car on and off and then shut it off and used the key remote to lock it. What is worse, while I was driving at night, I had my right blinker on to make a right turn, and I noticed the head lamps completely went dark when I turned and I didn't do anything, the head lights came back on by themselves. This is a very dangerous situation to be in. …
The check oil light never came on, it's a malfunction. The was no oil in the car, I have regular oil changes, but the engine ceased due to lack of oil and never any warning. Never "check oil light" or "oil low" nothing. When aaa towed they told me oil was leaking that when we checked. The engine is gone and costing me $2,600 to replace on a 2017 ugh. The car stopped in the middle of the street at 3 am in the morning. It was driving along and just stopped. The day before the check engine light came on and we had it checked out and the code was p0011 "intake camshaft position timing.
