2023 Hyundai Tucson Electrical System

Horn has been replaced three times and is now out for a fourth time.

my 2023 Hyundai Tucson has had the horn replaced twice. the technician indicated this is a common problem due to the location of the horn its susceptible to water damage rendering it useless. The horn is something rarely used and we were not aware it did not work until we tried to use it to alert a car entering our lane of traffic!

Approximately 2-3 months ago, the horn had failed. This was reported to the dealer and covered under warranty. During the service the dealer advised that this issue was due to a faulty electrical contact and was a “known issue with the supplier of the horn”. Because of this, Hyundai extended the warranty period on the horn. Now, the horn had failed a second time and was discovered during a safety hazard in which I needed to alert another driver. This had the potential to cause serious injury but was avoided.

The horn stopped working. I’m told by Hyundai service technician this is fairly common issue due to the location of the horns they are susceptible to “shorting out”

Purchased car in January 2033. I noticed the radio failed to work so I took it in to the closest dealership on May 10th. Dealership said there was a problem with the navigation system and the car needed a software update. Also advised, the update would repair some other electrical and system issues as well. Was told on 5/17 update would not be available until the end of May and that my carcshould not be driven so I should maintain the rental they provided. Lsstly, I have noticed some performance issues with shifting and speed as well. I thought update might fix, but after reading other complaints I will be reporting it to the dealership as well.

When I push the brake and push start button at the same time to start the vehicle, it will appear as if it is fully started. It is not until I put the vehicle in reverse that I notice the vehicle is not fully started. This happens on cold or hot starts and anytime of the day sometimes multiple times a day. The battery, malfunction indicator light, immobilizer, and engine oil pressure lights/lamps are on.The service department advisor did say my vehicle replicated but the vehicle was not hooked up to reader at the time. After that no service technician has been able to reproduce the problem. The vehicle has been to the dealership on 3 different occasions and I have provided them with a video.

The contact owns a 2023 Hyundai Tucson. The contact stated that while driving from a stationary position, the vehicle switched to safe mode and suddenly decelerated, and would not accelerate above 20 - 27 MPH. During the failure, the message "Limited to 20 MPH" was displayed. The cause of the failure was not determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 1,789.
