2024 Hyundai Tucson Fuel system Problems

“My 2024 SEL hybrid has a very annoying acceleration delay after a full or partial stop. The delay has occurred many times. It is present no matter which mode the car is on. It is not a matter of slow acceleration, but a 1-2 second delay of anything happening after I press the pedal. this could be a safety issue when you're at a stop sign and you need to proceed and you can't go.”

“On 6 occasions over the last 2 months when coming to a stop the engine will increase rpm to 1600 forcing much extra brake pressure to stop, forcing me to shutoff the engine. No codes or indicators and the dealer can't duplicate. I mentioned to the dealer that the car will accelerate while holding down the brake thinking that as a clue as to what's wrong and the service tech told me that is normal but as far as I know it isn't normal. I don't know what to do.”

“My wife was slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the AWD likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the EDR (event data recorder). …”

“On multiple occasions the vehicle has not transferred from EV to mechanical mode and has stalled out. Shutting the car and restarting it resolved the problem each time. Hyundai has not been able to find the fault after multiple trips to the dealership and no code is recorded or reported. I bought a code reader and the last time this occurred recorded a code. P1120 $07e8Pd I brought the car back into Hyundai and reported the code to- It was not saved in the car's memory. They have had the car for over 3 weeks now and repairs have not been completed.”

“While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. …”
