At 16,000 miles the horns on my vehicle failed. This occured on busy tollway just as a driver began to enter my lane from the right side. When I tried to engage my horn to warn him I was unable and had to slam on my brakes to avoid a collision. The driver behind me came within inches of rear ending me and he swerved into another lane almost causing another collision. Then the original driver thought I was brake checking him and went around me an slammed on his brakes in retribution. Horns that were used to repair by dealer were new OEM's. At 24,000 miles a similar experience occured where I had to slam on my brakes because I was unable to warn another driver that we were about to collide, but the horns failed. Once again the dealer had to replace the defective horns with more of the same OEM horns that have been proven by myself and others to be unreliable. In researching complaints about this issue I have seen numerous other owners of 23 and 24 Elantras (and Konas) making same complaint, some of which had to have their horns replaced multiple times. I complained to Hyundai Corporate and requested an alternate replacement horn as now I have to drive a 1 year old car that I don't know if the horns are going to work or not, and despite all the evidence I presented to them, they refused. I cannot allow any other family members to drive my $21,000 car for fear that they might not be as "lucky" as I was in avoiding an accident. I am told that the NHTSA does not consider a horn as a safety item and therefore not within their jurisdiction. I find that difficult to understand due to the lack of horns definitely put me in a position twice that directly related to my and the other driver's safety. What other reason could there be for a horn other than waking up drivers at a redlight who are looking at their phones instead of paying attention? I'm sure that when Henry Ford put horns on his cars that it was not for any other reason than safety.

Driver attention warning: Consider taking a coffee break comes on every 5 minutes. Very distracting to the driver. There is no option to turn this warning off.

We lease 5 Hyundai 2024 Elantra Blue hybrids that were bought new a few months back. We have experienced the same issues with 3 of the 5 so far. Cars will STALL at low speeds and sometimes ENGINE LIGHT goes on. Cars will suddenly not accelerate after stopping at a stop sign. Extreme danger for our drivers who are transporting developmentally disabled clients to outings and shopping, etc. Hyundai REPLACED throttle body replacement but same issues reappeared 2 days after getting car back. Now, Hyundai is claiming the GPS units plugged in may be causing this, but other 2 are not experiencing this issue (2 of 5). They refuse to work on further unless GPS units are out, but customer needs GPS units per insurance. So we need help from Hyundai in dealing with the dealer Zimbrick East of Madison, WI. We need the vehicles, but don't want our employees at risk.

Roughly over a couple weeks, I noticed when pressing on the horn it was NOT responsive when pressing the horn section of the steering wheel, so I took it over to Napleton Hyundai dealership, to take a look at the issue base on what they said, they would have to ordered the part however, it-??s on back ordered and would call when it arrives, my issues if the horn is of a safety issue, won-??t it be a better quicker response to get the part than get it fix" How many other drivers are having the same issue"

Yesterday May 26 2024 while my husband was driving he had on the air conditioner in our car. Suddenly the warning light went off that car was overheating. This also happened the day before. He was stopped at a light the 2nd time. The car has less then 7000 miles. We recently had the oil and air filter changed at Hyundai dealership. There was no problems at the time of service a month ago. All fluids were normal and everything seemed fine. I don't know why this happened. I googled 2024 Hyundai Elantra and another customer with EXACT same model is also have this SAME issue.
