2016 Hyundai Tucson

My car has an unresponsive accelerator pedal, delayed or no acceleration, jerking, shuddering, shaking, and stalling. The defects cause dangerous and unsafe conditions, including failing to shift, stalling and delayed or unresponsive acceleration, especially from a stop. I have been stuck on major highways and have had to disconnect battery and wait just to get the car to restart and actually move. I have had to be towed just to get out of the way of traffic

The contact stated that while at a complete stop, the vehicle would hesitate upon depression of the accelerator pedal as the wrench warning light would illuminate on the instrument panel. The contact took the vehicle to an independent mechanic where they changed the rear driver’s side tire and cleared the code; however, the hesitation persisted after the repair. The vehicle was taken back to the independent mechanic where they replaced the engine booster as well as eight bolts that had been fractured on the intake manifold while the booster was being replaced. Despite the second repair, the failure persisted and the vehicle was taken back to the dealer.

A warning light indicating that a brake light is out has been active for over 4 years. The bulbs have been replaced and checked and the brake light outage persists. This is an electrical issue and poses a serious safety hazard. Secondly, when trying to accelerate, the engine will rev between 400-500rpms but the car won’t speed up for several seconds. Lately while pressing the gas pedal the engine is revving in the 500’s while the car actually DEcelerates from 70mph to 40mph while ON THE FREEWAY. This is a mega dangerous safety issue for myself and other drivers. A mechanic quoted us yesterday as needing a new transmission. The car is 6 years old. In my opinion, these issues coupled with the existing recalls make this car a true lemon.

Engine Burns excessive oil, We change our oil every 3k miles since owning it sept 2019. I had taken it to the dealer for a repair on a separate issue and asked them to look at the engine and transmission due to noise and intermittent issues taking off. was told there was no issue and i did not need an oil change until I reach 5 k miles ( i was at 3k) and that the transmission has had the update and this is how the car operates noise and all, a week and a half later engine stalled while turning through a light at an intersection and the oil light came onfor a split second then off, no oil lights ever indicated low oil until that moment, I checked the oil and it was dry, I did an oil change, next time I reached 3k miles I took it to a shop, not the dealer and oil was dry at 3k miles, have had to refill the oil at 1500 miles since finding this out and have made multiple complaints to the dealer, they will not inspect it for what is a widely known issue unless i pay the money to do an oil consumption test that i cannot afford i have made numerous calls and have been unable to reach corporate after my first contact and delaer will not assist due to me being out of warranty even though this could have been prevented while i was in warranty and informed them i was having concerns, this company is aware of the issues these cars have and is knowing selling them when they can cause injury or death, as well none of my door handles will open the car upon first try(though this part is now under an extended warranty due to this issue) this company is knownly selling and doing everything not to recall dangerous vehicles

The vehicle issue began with needing an engine check light. Searched for a recall but there wasn't any engine recalls online for my VIN number. Took the car to the dealer for a recall and they did the recall on some electrical wire that was separate from the engine issue but they just overlooked the engine check light on my dashboard and made no mention of it. They actually bypassed it and so I thought maybe they fixed the issue since the light isn't present anymore. However the engine light came and the problem developed into a transmission failure. Upon pressing the gas pedal, the vehicle wouldn't run over 30 miles per hour and could only go up to 4 rpms.. I took the car to the mechanic and he replaced the transmission and he said that the root cause was a result of a burnt gasket. So we had that replace also.. After spending $5000 in repairs, the motor or the engine completely overheated and now the car is just a potato. Another issue is the doors on my car and not opening anymore. I have to manually ply them open by pulling on some mechanical wiring inside the door. Why do I have to pay for bad engineering? This is an obvious risk.

The transmission will fail to deliver power to the wheels when starting from a stop. You will hit the gas and nothing will happen for a beat, before kicking in suddenly. this creates a safety issue, especially when turning left, as it can leave you stranded in front of traffic. Multiple Tucson owners have reported the same issue with their transmisison.
