Car was completely dead. Because it is a PHEV, wheels were locked and the vehicle needed special equipment to be towed. Tow drivers (3 trucks eventually came) couldn't jump or charge the 12v battery. Traction batteries had a good charge. Locked wheels and sudden loss of all power makes this a safety issue.

New 2023 Hyundai Tucson purchased 9/9/2023 from Curry Hyundai in Cortland NY. On several instances of highway driving during the first 1,000 miles, on highways and at highway speeds, the forward collision avoidance system activated without any reason and applied the brakes at highway speed. This happened 6 or more times in only 6 or 7 highway trips during the 1,000 break-in period, and happened after the first visit to service for this problem, during which the dealer reset the system and sent me on my way, only to leave me driving a vehicle with the same, continuing defect. After the third service attempt, dealer and Hyundai have been unable to repair the vehicle (now with the dealer for over a week). Hyundai fails to even acknowledge its warranty or any other obligations to me, and all its communications show that it doesn't take these problems seriously, it has no standard process for dealing with them, and it offers basically nothing to the frustrated car owner. All its "customer care" department has done is check with the dealer, only to leave the problem with me for an unlimited timeframe.

The Hybrid system has twice now failed on this vehicle shortly after starting it up. The second incident, I drove not even 300 feet, got onto a main, very busy road, and the system made a loud grinding noise, error messages came on the infotainment system and dash and the car stopped moving. It basically stalled without stalling. I was nearly hit from behind but thankfully a quick thinking pedestrian noticed and flagged the car behind me to stop. It took 5 minutes to get the car to reset and move but meanwhile it kept saying I need to hit my brake pedal to shift gears. I was in drive and I attempted to use my brake, to park, reverse, etc and nothing happened. As I attempted to drive to turn my vehicle around and get home it kept telling me I needed to hit the brake pedal to shift the vehicle (an automatic). This is the second time this vehicle stalled in three weeks and it has already once been repaired.

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.

Unknown what fails. After driving approximately 30 minutes on a highway, car suddenly stops accelerating and bucks a bit as it slows. Must turn off car and turn it back on to accelerate again. Happens on the highway frequently. Very dangerous as there-??s no way to accelerate. Only stop. It-??s like it can-??t find a gear and the engine revs. It happened 6 times during a 2.5 hour drive.

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 began to hear knocking noise from the front of the vehicle that progressively got louder. Then immediately the check engine, brake, oil, key with car, battery, open doors, every light that the dashboard has came on. Immediately the whole vehicle lost power and I could no longer accelerate. The steering wheel got stiff and the vehicle had no response to brakes. The vehicle started stuttering.The engine died, RPMs at 0 and no response on the accelerator, brakes and steering. The vehicle would not start.I tried push start several times start the vehicle, remote start, app start and putting the remote close to the push start with no results.

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.
