Owner reports
Selected complaints filed with NHTSA by 2023 Hyundai Tucson owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2023 Hyundai Tucson. The contact stated while driving approximately 45 MPH, the accelerator pedal was depressed while merging onto a highway, but the vehicle lost forward momentum. The contact stated that the message "Limited to 20 MPH" was displayed on the instrument cluster. The contact depressed the accelerator pedal, and the vehicle failed to respond as needed. The contact stated that the engine was not revving. The contact pulled off the highway and into a parking lot. The contact turned the vehicle off and on, and normal driving was resumed. The contact stated that the failure was intermittent and was occurring while accelerating. Additionally, the contact stated that upon starting the vehicle in the morning, the vehicle would jump forward while still in park (P). …
The contact's son owns a 2023 Hyundai Tucson. The contact stated that while driving at various speeds, various warning lights illuminated, and various messages were displayed on the instrument panel; however, the warning lights disappeared upon restarting the engine. The contact stated that her son was forced to restart the vehicle after the vehicle failed to accelerate from a complete stop on one occasion. The vehicle was taken to the dealer for diagnosis; however, the dealer was unable to diagnose or duplicate the failure. The contact was informed that the vehicle could not be diagnosed unless the warning lights were illuminated. The manufacturer was notified of the failure, and a case was filed. The contact later received a letter from the manufacturer confirming the dealer's information. The vehicle had yet to be repaired. The failure mileage was 21,000.
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
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.
As I was parking my car in a parking spot going about 5 miles or less. My car surged forward at a very accelerated speed, and I ended up running into a brushed and a metal fence, which is what stopped me. There were no warnings that went off on my car. No emergency brakes, nothing.
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. …
The vehicle developed an intermittent but potentially dangerous engine control malfunction. After the engine reached normal operating temperature, the engine speed (RPM) would repeatedly surge while the vehicle was stopped in Park and Neutral, fluctuating from approximately 1,000 RPM to over 3,000 RPM without any throttle input from the driver. The condition occurred with the air conditioning turned off and could be reproduced multiple times. At approximately the same time, the Auto Start/Stop system stopped functioning and displayed a warning indicator. A malfunction indicator lamp (check engine light) also appeared during the incident. The warning light later turned off, but the engine surging continued. …
I received a Recall notice around January 2026 for the trailer hitch wiring harness on my 2023 Hyundai Tucson Hybrid. For 6 months the local dealer told me there was no fix available from Hyundai. I finally received a notice informing me that parts were now available and to bring it in to dealer for repairs. I took the vehicle in for recall repairs on May 27, 2026. Instead of repairing/replacing the wiring harness, Hyundai removed the entire wiring harness making the trailer hitch which I use for my business inoperable legally. When I noticed the wiring harness missing several days later, the dealer said that was Hyundai's "fix" for the recall issue. I contacted Hyundai USA Customer Service who also told me that removing the wiring harness and replacing it with an inexpensive dust cover was the fix. …
Horn on vehicle consistently goes out. Either goes out entirely or the volume of the horn is below a safe level. This is a known Hyundai issue and Hyundai refuses to acknowledge it on this specific model, but has acknowledged it on different models. I Have had multiple repairs by Hyundai directly, and the horn consistently keeps going out. There are sometimes in dangerous situations where I need to utilize the horn to avoid an accident and warn other drivers of danger, and I am unable to do so, and it causes dangerous driving situations. This is a known defect on multiple Hyundai vehicles in this year, but the Tucson is one of the few vehicles they will not call a voluntary recall on and NHTSA needs to be notified about this and act accordingly as a regulatory body to protect consumers and people on the road.
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.
