On two occasions, both on busy highways traveling at about 65mph the engine just quit running. Very scary but fortunately was able to drift to the side of the road and wait for assistance. The car was towed to the nearest dealer two hours from my home. After the fuel injectors were replaced it was returned to us two weeks later. It only had 9,000 miles on it. This is a very dangerous problem to just stop running with no warning. We could have been hit from behind and killed.

On Friday 05.26.2023 I was driving on the highway and lost all acceleration power to the vehicle and was almost rear ended by a semi. Iwas able to pull off the road but had no power of more than 2 MPH to do so. No warning lights came on, no engine error codes. I had the vehicle towed to the dealership pending review. I have only 1,355 miles on the vehicle. I am afraid to drive this car.

Attempting to enter I-295 South in Portland, ME at Exit 7 on March 18, 2023. We were in our 2022 Hyundai Tucson Hybrid Limited with approximately 6,000 miles. I tried to accelerate from the ramp to merge into traffic. The vehicle would not accelerate at all. I made several attempts to accelerate and nothing would happen. Pulled into the breakdown lane while applying pressure to the accelerator but it would not accelerate. The vehicle was in EV (electric vehicle) mode. After approximately 1 minute the vehicle did accelerate. No further problems that day. We called the dealership immediately and left a message regarding the incident. On Monday March 20th We followed up with the dealership and scheduled an appointment for the next day On the 21st of March We dropped the vehicle at the dealership. We picked it up at the end of the day and they told us they installed a software update TSB 23-EE-002H to repair the issue.

The car completely stalled while in the middle of driving. I was on the interstate and was unable to go at appropriate speed, making it dangerous for other drivers. This is the second time that this has happened. The first time, the dealerships said that it was a faulty fuel injector, and replaced it. However, 2 months later, the same problem occurred again. Because I wasn't in an accident, the car was not inspected by anyone other than the dealer. I did not receive any warning lights or symptoms.

I am an active-duty service member who purchased a new 2022 Hyundai Tucson Hybrid on 16 October 2021. The car occasionally makes a strange humming noise while the vehicle is completely turned off. I recorded my car making this strange noise, and the video recording can be seen at https://youtu.be/bY8GJenoWBQ. I had previously notified Hyundai Maintenance of this during a scheduled vehicle check; nothing was done to resolve this matter. The advertised fuel economy on this car is 36/37/37 (city/combined/highway) Miles per Gallon. I am currently getting 28 MPG (see attachment), which is approximately 30% below the advertised fuel economy. Since I purchased this vehicle, it has consistently delivered a poor fuel economy well below the advertised fuel economy. After trying to resolve the poor fuel economy issue with Hyundai for 9 months (see attachment), I reached out to the Better Business Bureau seeking a resolution. On 17 November 2022, I was notified by the Better Business Bureau that Hyundai rejected my proposed resolutions of Hyundai repairing the car under manufacturer warranty or replace it if unable to fix the poor fuel economy, as well as reimburse me for money spent due to excessive fuel consumption. Additionally, other persons have reported their Hyundai cars delivering a fuel economy much lower than advertised (visit https://www.reddit.com/r/Hyundai/comments/nwayqv/2022_tucson_hybrid_poor_gas_mileage/). I have the perception that Hyundai lied and deliberately deceived me. Something is wrong with my car, and Hyundai has been either incompetent or unwilling to repair the issue under the car manufacturer warranty. I believe that it's important to hold companies such as Hyundai accountable. Otherwise, it would have no incentive for doing what is right. I request your assistance with investigating, and if possible, taking actions to hold Hyundai accountable for deceiving consumers by exaggerating its car fuel economy.

With approximately 6552 miles on the car, 7 months after I bought it new, the Vehicle sputtered and shut off. The GDI pump was replaced. It has not runnright since. It sputters, it does not respond appropriately when the accelerator is pressed, it went into limp mode and would not go more than 35 mph. It did not throw and engine code when this happened. This is a huge problem in itself. I could be out of oil and it potentially will not throw a code or warning. When the dealer had it for 45 days they drove it approximately 100 mile and could not duplicate. It is a serious danger to my life and I refuse to drive it. I had it towed and it now sits in my driveway will the lemon law case is processing

My wife was driving on the parkway north in New Jersey at approximately 65 miles an hour at about 3:45 pm. The car began to lose power, was shaking, and sputtering. Luckily, she was able to pull onto the shoulder and did not get hit by another car or truck. Once she pulled over, she let the car rest for about 10 minutes and started it up again. It hesitated, but started. Once she put it in gear, it stalled. she tried this two other times and it stalled each time. she waited for a tow truck and the care was towed to the dealer. The dealer invoice with repairs is attached.
