The contact owned a 2023 Hyundai Tucson. The contact stated that while his mother was driving at an undisclosed speed, she heard an abnormal sound emanating from an unknown location of the vehicle, after which the vehicle began to accelerate on its own. The driver attempted to stop the vehicle, but the brake pedal pulsated and failed to slow the vehicle, resulting in the driver briefly losing control of the vehicle and only coming to a complete stop after colliding with a utility pole. Both the driver and passenger side air bags deployed. No warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider. A police report was filed, and injuries were reported. The driver and passenger were both transported to an area hospital by EMT and treated for injuries to the chest sustained from the air bags. The manufacturer was not notified of the failure. The failure mileage was 10,000.

When pulling out of my driveway onto street, I lost acceleration. My vehicle would not go oer 35 mph and the RPMs were revving up too 5000 without speed moving. I tried changing the drive mode to fix it, that did not help. I pulled over, s topped the car and restarted and all seemed normal. This has happened 2 other times since I bought the car. The other 2 times was while i was on the interstate the engine stopped engaging and i could not accelerate. Both times the issue corrected itself by the time I could get safely out of traffic. This is a major accident concern as there is no warning before this happens.

This Hyundai Tucson was 3 months old when the transmission started to shudder and miss gears. I immediately took it in to Ken Garff Hyundai and the service advisor drove the car and said nothing is wrong with the car and that the transmission needs to break in and sent me on my way. The Tucson did it again while in traffic and the vehicle would not go and I had to put my hazard lights on and let the car struggle in changing gears to get it off the road. The car was towed in to Peoria Larry Miller Hyundai and this was documented by that dealership of the car shuddering and that they thought it was from my insurance plug in device. I explained that the car did it before the plug in. I removed the plug in device and the car continued to shudder. On [XXX] while backing out of my garage the car began to shudder while in reverse and i continued down the road while the transmission refused to change gears. It almost sounded aa if the car was in neutral and the car would on go no more than 3mp. I had the gas pedal floored and the car would not go. I reparked the car back at my home and called Hyundai for a tow. The tow came and the tow driver stated that the seemed as if it is in neutral as he drove it up on to the tow truck. After getting the vehicle to the dealership i was told from the service advisor that this is an ongoing problem with Hyundai's dual clutch transmission and this sounds like the problem.

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.

On four occasions in the last five weeks, I have been driving at relatively low speed (20-30 MPH), and when I attempt to accelerate, the vehicle will not accelerate when I press the gas pedal. The tachometer shows the RPMs are maxed out, but the vehicle does not accelerate no matter how hard I press the gas pedal. I have to pull off the road, turn off the vehicle, and restart to fix it. I am certain I have not accidentally hit any buttons or switches each time. I have tried changing drive modes (eco/normal/sport) and using the paddle shifters and that has no effect. Cruise control is off, and no other speed limiting system is activated. There are no warning lights or indicators when this occurs. This is incredibly dangerous, as I am unable to get up to speed on a main road. A few instances led me to be unable to successfully merge onto a main road, which has led to me almost being rear-ended on one occasion, and the most recent instance I was in the left lane of a main road and attempting to pass a large truck and could not maintain speed. I was fortunate to come upon a slight downhill slope and was able to coast across the right lane and get off the road, but it was a near-accident. The dealer service center was unable to diagnose the issue, and therefore could not repair it.

When vehicle is just slightly moving and the accelerator is depressed, the vehicle does not respond, zero acceleration. This issue is repeatable and poses a hazard when cross traffic is coming. Wether in Eco, Smart or Sport mode, it has this non-accelerating issue.

My suv is a hybrid. I slowed down before making a right turn to check if it was clear before continuing with the turn. I see one car and its pretty far away. My gas engine switch off to go into EV. I step on the gas and my suv goes no where for about 5 seconds. Now the car down the street is approaching me fast. Finally the gas engine kicks on my suv started moving. The other car honk and went around me.

Two times in the last two weeks of March and about 10 times since we purchased the vehicle new in December 2022, after starting the vehicle and backing out of our garage onto our street, then stopping then shifting from reverse to drive and going no faster than 15-20 mph for about 300 yards, the Tucson revs up to about 3ooo-3500 rpm and will not shift into second gear. After about 1 minute or so it seems ok. But until then the transmission does not shift smoothly like it did the first six weeks of ownership. It did not operate like this until about the beginning of February. Something is not right with the transmission. I suspect his will be difficult to diagnose since it is intermittent. Want to get this documented and checked out before this becomes a major problem. This is also a safety concern since the vehicle is limited to about 15 mph and could cause an accident if it malfunctions when pulling out onto the street and there is following traffic. Our vehicle has been at the dealership since April 7th waiting for approval and installation of a new factory transmission. Was supposed to be completed yesterday or today, but no info from the dealership yet. I suspect this may not have resolved the vehicle defect.

I bought a 2023 Tucson SEL from Rohrman Auto in Lafayette, Indiana It had a major drive train failure from the factory This is Failure #1 and should have been caught at the factory upon inspections I did not want to buy a vehicle from Rohrman that had a problem This is Failure #2 as the dealer admitted that they should have caught this defect in their inspections before they sold it It took me over a week to get the dealer interested in the problem. I do not want this defective car. This is Failure #3 as the dealer has pushed the resolution of this problem on me and is generally unresponsive to my direct, clear, and respectful requests I made a case with Hyundai Customer service (Case # 21183458) requesting the same. This is Failure #4 as the customer service system seems to be broken, and left me stuck between a staff turnover problem there -?"> As you can clearly see, HMUSA's manufacturing and quality checks failures have been compounded by customer service failures by both the ROHRMAN and HMUSA that now leaving me stuck with a major problem. I simply want a new, defect free Tucson SEL in Amazon Green or Sea Blue. You can have this defective vehicle back.

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.
