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,…

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 rear turn signals on the 2023 Hyundai Tucson are on the rear bumper. They are never seen by any car or truck sitting behind you or next to you in your blindspot. I believe the 2022 & the 2024 also have this issue, and there are numerous complaints about it online, especially on Reddit and auto forums. They are dangerous. Cars too close behind you or next to you in your blindspot, will never see your signal, especially the larger cars & trucks or tall autos such as buses, garbage trucks, etc. Here is one of many articles & videos about this issue: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

When driving the car and stopping at red lights, stop signs, or any other stops in traffic on roads and expressways, the car engine randomly dies and cannot restart between 3 and 10 mins. There is no warning when this is about to happen – the car engine simply dies and dashboard lights come on. There is no response from the car after shifting in Neutral or Park by pressing the start button with foot on brake. After some amount of time, the car will start. There is no warning before this is going to happen. The dealer (Patrick Hyundai) has inspected the car three times and has not been able to reproduce the problem as this happens randomly. They told me on my third visit to not bring the car back as they don't know what the problem is. The first time this happened was 4 months after I owned the car and has happened in excess of 6 times I now fear for my life when I drive this car. I was almost hit twice. I was stopped on a busy main street at a red light when the light turned green and all cars drove away and the truck approaching me assumed I would drive also but couldn’t because the car was stalled in the middle of the road. The truck veered away as last second to avoid my stationary car. The 2nd time was on expressway during traffic when stop and go driving was occurring and my car engine died again. As in previous case, vehicle behind me anticipated I would move forward like other cars but couldn’t and stopped inches from back bumper.

This is copy and pasted from your site. Hyundai does not have a recall ready, so I am filing a complaint. Is this the correct action? THE TRANSMISSION ELECTRIC OIL PUMP FOR THE IDLE STOP & GO SYSTEM (ISG) IN THE SUBJECT VEHICLES MIGHT HAVE BEEN ASSEMBLED WITH PRINTED CIRCUIT BOARDS (PCB) THAT WERE DAMAGED DURING MANUFACTURING BY THE OIL PUMP CONTROLLER SUPPLIER. A DAMAGED CAPACITOR ON THE PUMP CONTROLLER PCB COULD IMPACT ELECTRICAL OPERATION LEADING TO HEAT DAMAGE TO THE ELECTRIC OIL PUMP CIRCUIT BOARD, CONNECTOR, AND WIRING HARNESS. THE HEAT DAMAGE AT THE PUMP INCREASES THE RISK OF A VEHICLE FIRE IN ADDITION TO A POTENTIAL CONTROLLER AREA NETWORK (CAN) COMMUNICATION DISRUPTION FOR MULTIPLE ONBOARD CONTROLLERS. Thanks for your time.
