Chronological view of owner reports
Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.
Low pressure oil light did not come on until the oil drain plug had completely fallen out. Once the light came on, the vehicle was slowed and came to a stop on the side of the highway within 2 minutes. The car completely shut off as if the battery were dead. It had to be jumped in order to put the car into neutral for the tow truck. The safety issue is that the hwy we were traveling on is 70mph. At no time, did we receive a warning until it was almost too late. The car is currently at an auto repair shop as the engine is most likely catastrophic and due to the car having no power, they want to replace not only the engine but also the 12 volt battery and it's module. The low pressure oil warning should have come on way before the plug completely fell out and the battery should not be dead. The mechanics can't even fathom why an engine would fail quickly and drain the battery as well.
The HORN has been replaced on 4 separate occasions through Hyundai under warranty and it can not be fixed. This seems to be a wide spread issues involving the 2023 and 2024 Hyundai Elantra models and there are multiple TSB's at the dealerships. Hyundai has not done a recall or come up with a fix and it renders the horn useless and can cause a major safety problem or accident.
Hi horn and low horn stopped working after 1 1/2 years of driving and only 7000 miles. This is a safety recall because it will fail West Virginia state inspection without the horn working. Also, it puts myself at risk while driving because I can't alert oncoming traffic if they are heading towards me. This could cause an accident. Hyundai Service Center will be inspecting the issue on 05/07/24.
The horn constantly fails and needs to be replaced. This is not only an issue with the Elantra, as I've seen it as a common issue among a range of Hyundai vehicles. Even my local dealership has many horns on hand, as it is so common for them to be replaced, as they stated. I've gone through 2 horns in less than a year. This is complete negligence on Hyundai's part, as the horn is a critical safety feature of any highway vehicle. They replace it knowing it's going to fail, completely disregarding the safety of both the operator and nearby car and foot traffic.
