2023 Hyundai Tucson acceleration problems

Filed Nov 8, 2026 · Acceleration, Fuel system · GA

I am the original owner of a 2023 Hyundai Tucson with approximately 56,000 miles. I am reporting a recurring safety issue involving sudden loss of engine power and acceleration while driving. I previously experienced a similar incident at approximately 50 mph, when the vehicle struggled to accelerate. Hyundai of Cumming inspected the vehicle and, on XXX, at 44,199 miles, replaced the high-pressure fuel pump and fuel pipe (Repair Order XXX). Despite this repair, the same issue occurred again on XXX. The engine struggled to gain RPM, and the vehicle would not accelerate properly. There were five occupants, including my [XXX] daughter and her [XXX] friend. Fortunately, I avoided an accident, but this could have resulted in a serious collision. I regularly use this vehicle for family transportation, including school and daily activities, and my commute involves approximately 25 miles of driving each way, including highways. Unexpected loss of acceleration is extremely dangerous, particularly when merging or keeping up with highway traffic. The vehicle is currently parked because I no longer consider it safe to drive. I am requesting an investigation into this recurring loss-of-acceleration issue in 2023 Hyundai Tucson vehicles, including whether a defect involving the fuel delivery system, high-pressure fuel pump, fuel pipe, or related components could cause sudden loss of engine power while driving. This problem poses a serious risk to the driver, passengers, and other road users. I am also attaching the hyundai repair invoice from last year for your reference.

I was on the highway on the way to work when my car started stalling. Every time I pressed the gas to give it some power, it would not go anyway where. after getting it towed to get looked at some of the fuel injectors failed and were misfiring. The warning message about ‘check engine’ popped up 2 minutes before it happened. this is the third time now in less than 6 months.

As I was pulling into a parking space in a parking garage, the vehicle's engine revved, tires squealed and then the vehicle propelled forward on its own, without my foot being on the accelerator. The vehicle only stopped when it hit a support column and the wall of the parking structure. There was extensive damage to my vehicle and to the parking structure wall. My safety and the safety of others was put at risk due to the car accelerating on its own. The problem has not been confirmed or reproduced by the dealer, but we did take the vehicle to the dealer for inspection and they said they could not find anything wrong with the vehicle that would have caused the unintended acceleration. The vehicle has been inspected by the manufacturer, the insurance company and an investigator for Hyundai. Hyundai infomed us that they are not taking any responsibility for anything that occurred and that they will not share their investigator's report with us. There were no warming lamps or messages related to the problem prior to the failure. However, there have been other occasions while driving on the open road when the engine has revved on its own and I told Hyundai about that. In doing our own research, we have found that there are other 2023 Hyundai Tucson drivers who have had this exact same problem (unintended acceleration causing a crash) while pulling into parking spaces. Additionally, the air bags did not deploy during the collision and therefore the incident was not recorded by the EDR.

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.

My 2023 Hyundai Tuscon has 36000 miles. Started running rough with a slight noise. First noticed on Wed [XXX]. On Thursday [XXX] I went to start my car and it stalled. Finally after letting it sit a few minutes it started but only to have the SGI light flash yellow and stay yellow for the remainder of the drive. That day I made an appt at my local Hyundai Dealership in Brandon Florida. They kept my car. Fast forward, Monday September 15th I was notified that the car had lost a significant amount of oil. Car was inspected and free of any leaks. Tech stated because of the low oil & oil pressure the battery life was significantly impacted. I would need an oil change & new battery. Upon arriving back I came across an article stating that excessive oil consumption is common among these vehicles and the dealer wasn't even going to notify me of this issue. They were not honest and I want to file a formal complaint knowing that this is well known issue. I feel unsafe driving my children around and am upset that a recall has not been issued to fix this.

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so.” Yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black.box Should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson Owners’ group on Facebook, and my incident has been reported by others.

2023 Hyundai Tucson with just over 14,000 miles failed to accelerate. After completing a right turn the vehicle seemed like it went into neutral. A green warning light appeared stating limit 20 mph. I now know this is “limp mode”. Turning the vehicle off and back on seemed to resolve the issue. The vehicle was towed to the dealer. They found nothing wrong. I was told to take a picture of the warning next time. I was fortunate to not have caused an accident. This is incredibly dangerous.

Attempted to make right turn onto busy road. Tried to accelerate to move with the traffic, when the car would not go any faster then 20MPH. Could hear cars braking behind me. Pulled over to the side. Message appeared on speedometer, " Limit 20MPH" with green Speedometer. Shut the car off tried to find problem in the manual. Didnt find anything. Turned car back on, it ran normal. Took it to Hyundai, Fort Myers, Appointment, on 08/28/24. They diagnosed it as : "driver assist speed setting was turned on inside settings. Turned off setting, performed a DTC code scanning with no dtcs in any system. Attached stui photos, performed a 2 mile test drive with no further issues". I can only hope that the problem is solved. I do not recall turning on anything like, and wouldn't know how to, but I guess it is possible. Wanted to notify the federal safety agency, in case there are other owners experiencing the same issue. Thank you for concern
