2023 Hyundai Tucson Hybrid

The contact owns a 2023 Hyundai Tucson. The contact stated that while driving at slow speeds and attempting to park the vehicle, the vehicle unintendedly accelerated before the contact was able to regain control of the vehicle. The following day while driving away from a stop light, the vehicle briefly shuddered and was unable to exceed 20 MPH, prompting the contact to pull to the shoulder of the roadway. After restarting the vehicle, the vehicle returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 3,000.

While driving the vehicle, the acceleration stopped and the car came to a halt right in the middle of the road. It acted like the battery drained and the gas did not kick in. The only fix was to shut it off and turn it back on. Took it to dealership they said they couldn’t find anything wrong with it so we picked up the car and as soon as we drove off, it happened again. This could result in a fatality if it happens on a busy highway since there is no warning and it just stops working. Took it back and the dealer says they can’t find anything wrong. Although the receptionist said they are aware of this because they call it a “limp” problem because the car goes limp. The second time it happened we took a picture of the dash.

2023 Hyundai Tucson Hybrid Blue Issue: no power /accelerator response from slow speed. Since 4/23- 9 instances involving this issue none resulted in crashes but did result in near misses and 2 cases coasting off the edge of the road to avoid being hit. 6 of the instances happened when attempting a left turn in traffic at an intersection. 3 of the instances involved when trying to enter a traffic circle(turning right). In all of the instances the vehicle was in Eco mode. Description of Intersection Instances: Left turn with a blinking yellow arrow traffic light signal. I approached the intersection in the left turn lane slowed and was coasting forward. The vehicle had shift to EV mode. There was a gap in oncoming traffic and I hit the accelerator to cross. No response I pressed the accelerator to the floor and still no response. I lifted my foot off the accelerator and jammed it back down and had power but now the oncoming traffic was on me. Fortunately, only one car that did hit their brakes and honk. This same scenario happened two more times at the same intersection as well as three other times in city traffic. No power when entering a traffic circle: I approached the traffic circle slowed and coasted forward waiting for the cars in the traffic circle to clear. There was a gap and I hit the gas and not power. Pedal to the floor and no power. Traffic was on me and I turned the steering wheel hard to the right and drove off the edge of the road to not get hit. I had three passengers with me at the time. The same scenario happened two more times- where I hit the gas no response but these times I let up off the accelerator all the way and then pressed it down and had full power. This resulted in about a 3-4 second delay from when I first realized I did not have power to having power. I did check 4 a recall and none found. However, I did notice another complaint citing the same issue w-Hybrid on NHTSB site. but in error listed under reg Tucson.

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.

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.

AC system is not functioning properly. Having the car on for 20 minutes, Ac system does not kick in allowing the car to cool properly. This happens when Temps are above 95 degrees. This is an issue as it could lead to someone passing out as someone is driving a car. As the Temps of outside and inside of the car compound as the cabin can't cool down. Serious issue as a car should cool down with 5 to 10 minutes. Car rarely blows cold air and ahould not be operated in hot environments.

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.

My son was backing out of a parking spot at a strip mall. He released some pressure on the brake and indicated that the car lurched backwards and even though he reapplied full pressure to the brakes, he hit the car at the curb resulting in damage to our Tucson, but luckily not the to the other car. The Rear Cross-Traffic Collision-Avoidance Assist system did not engage, but my son indicated that the rear distance warning system did beep. I am concerned due to the sudden acceleration/lurching incident my son experienced and this is not acceptable in any car. I ask the NHTSA to see if other Hyundai Tucson or Kia Sportage owners, especially with the Hybrid engine are experiencing this.
