1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, RPMs spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. Had we been on the interstate we would have died, These incidents were sporadic and occurred on and off during the month of April and May. Each of the above occurred numerous times to different drivers. Service at two locations were unable to ID. We sold the moving death trap to one of the Hyundai dealers who could find no mechanical problems with the vehicle. The vehicle was terrifying to drive. There are other reports on this vehicle of these issues... which appear to be electronic. Hyundai has good engineers. They know what is causing this and simply do not want to replace a very expensive but obviously failing electronic control module.

- Hendersonville, TN, USA

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.

- Cleveland Hts, OH, USA

The car turned off while I was driving. Everything went black. I was able to coast to the side of the road.

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-??

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.

When the vehicle was started the SRS light remained illuminated and when driving the vehicle over 40 MPH the abs, traction control, collision avoidance, and start-stop lights on the instrument cluster come on and remained on. The adaptive cruise control, nor the button for the start-stop deactivation work. The vehicle has just over 500 miles on the vehicle and is less than a week old.

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.

I purchased a new vehicle in February 2023. After a month and a half, I traveled to Washington DC on a pleasure trip. After my work/vacation trip when I am returning back to home all of the sudden, there was heavy smoke from the hood and eventually tried to turn off the engine but the car didn't respond, and when I tried to open the Hood in order to cool down the engine I see fire already in the engine. So, there was no intimation on the dashboard about the fire or not even an alert. Moreover, the engine didn't turn off even after trying to turn it off 4- 5 times. I was really worried about what would happen if the door locks stops working

I just bought the car, it was brand new off the lot. The check engine light came on followed by every emergency warning on my dash. After this my power steering failed, I was able to move over to the right lane a bit, but that-??s it. I tried turning the car off at this point and turning it back on, but it would not turn back on. I could not even put on my emergency 4 way blinkers. The car would not even detect the key at this point. Thankfully we were on a small, low traffic road and not the freeway or a major accident would have been inevitable.
