2014 HYUNDAI SONATA Complaints

Headlights will randomly flash off/on while driving. Using turn signals will also make the headlights (and some interior lighting) flicker off/on. Headlights were replaced, but problem still exists. This is a major safety issue for me as other drivers believe I'm flashing my lights intentionally, not to mention, driving at night and having your headlights turn off randomly isn't very safe. We feel very unsafe driving this vehicle after dark because of this issue. This problem started at approx. 70,000 miles. Took the vehicle to the dealer and was told the issue is a defective multi function switch and that others are having the same issue. However, but the dealer said this issue is only covered by the warranty up to 50K miles and I would have to pay to have this resolved. I contacted Hyundai Consumer Affair's and opened a complaint with them. I was assigned case number 18855023, but was told there isn't anything Hyundai could do and I would need to deal with my dealer to get this repaired out of warranty. From my research I've found that many other Sonata owners are experiencing this same issue and that some of the Hyundai Genesis line of vehicles also are experiencing these issues, but in response to these Genesis owners, Hyundai has extended the warranty of the multifunction switch assembly to 15 years with unlimited miles from the date of original retail delivery or date of first use (whichever occurs first). Why is Hyundai not addressing this same issue that exists on their other model lines??? Hyundai needs to extend the warranty and repair this defective switch for ALL other Hyundai models. This is a very unsafe and potentially life threatening hazardous issue that needs to be address for all Hyundai customers and not just the Genesis owners.

I’ve had my car for a year and I change the oil faithfully. Well I now have a rod knocking and not sure why? My car has 138,000 miles on it. And I’ve changed my oil and filter as I should so now my car is sitting in the yard it cranks but when you crank it you wouldn’t think anything was wrong with it. You give it gas and it starts knocking. Why is this happening?

I brought my 2014 Hyundai Sonata Hybrid in for the 964- AUXILIARY CANISTER INSTALLION & 966- ENGINE MONITORING LOGIC Service recall campaigns on 12/08/21. Today, 12/21/21, in heavy traffic on the highway, my car engine abruptly shuts off, immediately decelerating, completely losing any ability to accerate while the engine light, parking break light come on along with an "electric motor warning - safely pull over and do not drive" message on the dashboard. All this happens while a high pitch alarm goes off. All happening simultaneously without warning on the highway with vehicles surrounding us driving 70 mph! This has never happened prior to today and should never happen. How we managed to avoid an accident or worse was a miracle. This was life threatening and should not be taken lightly!

Vehicle died while driving on the highway had to pull over and have the car towed. Hyaundai dealership diagnosed it as a bad engine bearing which was part of an open and active recall which they confirmed. Hyaundai advised it is part of a recall that is still open but stated we didn’t come soon enough so they refuse to fix it. We never received the recall notice and the recall is still open and active.

Engine needs to be replaced, engine light, brake light and loud ticking sound in engine

I purchased this car on November 17th, it started giving me trouble on November 25th so i parked it. The problem was it started making a really loud noise and started to slow down in mid traffic while i was driving. i had to bear to the side of the road to avoid a car crash. i think it’s the motor , i’ve purchased a brand new battery and starter and neither of those was the problem. my car have been sitting every since the 25th i need to know what’s wrong with my vehicle beside the recalls i have on it!
