2025 Hyundai Tucson Powertrain & Transmission Problems

The car was backing out of a driveway in Reverse. Came to a stop to shift to drive, and recieved a "shift system malfunction! Service immediately" screen message and the car was locked in the middle of the roadway unable to be put into any gear or be turned off. It was a huge roadway safety issue. The tow driver had to search for a code or sequence of commands to put it into neutral to be able to be safely lifted onto the tow bed, and the vehicle was stuck in accessory mode, which effectively drained the battery.

As of today, March 17, 2026 , my 2025 Hyundai Tucson keeps having safety issues. On March 8th , 11th, 14th and 25th the car once again shut down mid-drive. This issue occurred last month as well but dealership claims no DTCs were found. I am noticing that the forward collision warning comes on without any cars or objects in front periodically since the purchase of my car. The light will remain on for a few seconds and disappear. The automatic brake system seems to be causing issues as well which I believe causes the car to shut off completely mid-drive. Once the car shuts off the panel lights turn on to include the engine light, but then after a few seconds I able to change gears back to park in order to turn car back on and continue driving. This has happened now several times since last month. However, I have had issues with my brand new vehicle since I purchased it last year. My car remained in the dealership for 3 months last year due to an engine, ac and power train issues. Prior to the car shutting off, No actual warning lights illuminate other than the forward collision warning light and the notification of headlights are turned off even though it’s daylight and headlights do not need to be turned on . Periodically and intermittently an alert about consider taking a coffee break alert has also popped up in the past. It seems Hyundai has a severe issue with the FCA operating system and over 100 complaints have been made about this vehicle nationwide and no recalls have been issued. I am afraid for my life and the life of others on the road as this car should not be stopping and shutting off while driving for no apparent reason.

This has happened at least 6-10:times. We park the car put it into park and the car lurches forward. Once the car hit a sign in front of it, a few times to hit the transient in the ground in front of the car. Car was taken to the dealer and the mechanic could not get the event to occur. Nothing occurs prior to the vehicle lurching forward. Issue has been reported to the manufacturer case number assigned but manufacturer refuses to do anything about the issue. Case number is XXX. As I have written to the manufacturer - we are concerned that this may occur with a sold wall, another vehicle or good forbid a human being in front of the car.

I am reporting a serious safety and reliability concern with my 2025 Hyundai Tucson. At only about 2,000 miles, I was informed by the Hyundai dealership that the transmission has already failed and needs to be replaced. This vehicle is essentially brand new and should not be experiencing a major powertrain failure so early in its lifespan. The transmission issue has caused significant concern regarding the safety of the vehicle. Sudden failure of a major drivetrain component creates an increased risk of loss of power, unpredictable drivability, and unsafe operation in traffic. This is especially concerning because this vehicle was already given to me as a replacement for a previous Hyundai Tucson that qualified under my state’s lemon law. A transmission failure at such a low mileage indicates a possible manufacturing defect or a systemic quality issue that could affect other consumers. I am requesting that NHTSA investigate this matter to determine if this is part of a broader problem in the 2025 Hyundai Tucson model line. This situation is unacceptable for a vehicle this new, and it raises serious concerns about long term safety and reliability. I am seeking further review and action so that other consumers are not placed in similar unsafe situations.

engine RPMs surged and the car accelerated forward without foot on the gas pedal concerned about possible pedestrian accident or collision with objects and prop. damage. dealer was unable to duplicate the problem and no repair was made there is no warning...I never know when it will happen and it has occurred in a number of different circumstances

I bought a Hyundai Tucson Hybrid 2025 on Aug. 7, 2025. My car has 1541 miles on Oct. 8. I tried to drive my car out of the garage, and the engine would start, but it wouldn't move forward or backward. There were three warnings on the dashboard: Powertrain, hybrid, and something. Hyundai headquarters called and said there was a problem with my car. They will send a tow truck. It has been one week since my car was taken to the dealer. I haven't heard back. When I called today, they said there was a problem with the TCM and they ordered a module. So, I guess I just have to wait and see.

While driving my car to Virginia to see my daughter, the oil light came on in the middle of a highway, where the speed limit was 70, The car slowed down and I had to pull off to the shoulder as the car lost all acceleration, making it very dangerous on a highway I waited for about 2 hours for a tow truck I waited for almost 2 months to get my car back and it happened again after having it back for a little over a week Mind you, I bought the car brand new with 45 miles on it and the first problem happened a little over 2 weeks after I bought it Hopefully this can be resolved so that my car doesn’t spend more time being serviced than me driving it

Car would not go over 25 MPH.Had to pull to side of the road.I had to turn the car off and on then it ran normal.

The following problems began 5 months ago, 8 months after purchase with about 4770 mileage and current mileage of about 7623: Multiple occurrences of Check Engine light coming on, sometimes setting DTC code, but often not setting code. Multiple occurrences of Crash Warning light coming on; It may have set a code or codes, but usually not. I think neither dealer was able to reproduce these 2 intermittent problems. Engine light, so far, has not occurred since it was traced to faulty connectors. As far as I know, the Crash Warning light has not come on since the dealer reduced front camera sensitivity. Also, for the past 5 months there has been intermittent, engine miss, skipping or cut-out. As of this writing it still occurs while driving and will lurch or buck if it happens under acceleration This is not frequent, but it happens erratically and it may happen only once or a few times in one day or several days between. This has not set a DTC code as far as I know; I think the following may be related to the skipping. Once, while coming to a stop, the engine stopped or almost stopped; it bucked when it happened, but continued to run. All warning lights came on for a second or two, then went off, except 3 warning lights and the warning triangle. Although the engine was running, the tachometer and speedometer read Zero. The engine bucked as I slowly drove into a parking lot, then I restarted the engine; it seemed ok, then. About 3 weeks later, while driving at slow speed, just as I took my foot off the brake and was about to accelerate, the engine quit. When the engine quit, the audible Crash Alarm went off with a message saying the engine was not running, press the start button. I started the engine, it did not have normal power. I stopped, restarted the engine and it seemed ok. I have been to the dealer several times because of these problems; dealer is still troubleshooting the last incident. This could cause an accident, especially if it occurs at a higher speed.

The contact owns a 2025 Hyundai Tucson. The contact stated while driving 24 MPH, the vehicle shuddered abnormally. After releasing the accelerator pedal and slowing down, the shuddering ceased. There were no warning lights illuminated. Additionally, the Auto STOP/START feature failed to activate as designed. The vehicle was taken to a dealer where it was diagnosed and determined that the electric oil pump needed to be replaced. The vehicle was repaired but the failure persisted. The dealer then diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.

This vehicle has had numerous problems since I leased it. To summarize, at times the vehicle randomly shifts out of the ECO mode, usually into the SNOW mode. The engine has also raced, hesitated, bucked, rattled and vibrated when trying to change gears. Sometimes, these actions are subtle and sometimes they are borderline violent. This happens more frequently when the engine is cold. Additionally, the AEB system has activated a number of times while in stop and go traffic, even though the vehicle in front was moving forward. On at least 3 of these occasions, i barely avoided being rear-ended by the vehicle following me. The final issue that I have noticed is a problem with the odometer. It has appeared to work normally most of the time, but I have noticed times where I didn't think the odometer accurately reflected the distance I had traveled. I was able to synch the odometer with the trip odometer on a local road that I was quite familiar with. The trip odometer registered 1.8 miles while the odometer only registered 1 mile traveled. All of these issues happened multiple times and are intermittent. I have had the vehicle to Hyundai dealers on 5 occasions, and they claim to have not been able to duplicate any of the problems that I have been consistently logging in to a "diary" that represents a list of when I have noticed these issues. I have been in constant contact with Hyundai, but they promised to send out a factory rep, then reneged, instead relying on the local service techs. Said techs had the vehicle for nearly 2 weeks, but only drove it for 16 miles (until I called AFTER a determination was made and they hurriedly drove it an additional 22 miles to give the appearance of a more complete exam), using less than a quarter tank of gas. To me, this wasn't a thorough exam and appeared to be a cover-up to avoid having to buy back the vehicle. Note: these problems have occurred on multiple occasions, therefore the date below is the lease date.

-auto start/stop "feature" Since there is no way to permanently disable this feature i forgot that it was on. while stopped a stop light i was unable to move when the car behind me could not stop due to the wet roads. If the car behind me was unable to swerve in time i would have been rear-ended. by the time the engine started the car behind me was in line with my back seat. no amount of gas saving is worth being immobilized essentially in a emergency situation. - forward collision avoidance is way too sensitive, in the same trip as above a car hit their brakes approximately 6 car lengths in front of me to turn into a parking lot. the car in front of me did slam on their brakes to make the turn. As i took my foot off the gas to slow down the "safety feature" activated, applied my brakes and almost caused the car behind me to rear end me. i was going roughly 45 mph and the car behind me was roughly 2 car lengths behind me when the "safety feature" activated. the sensitivity of this system is way too high and will wind up causing more accidents then it prevents
