While driving on October 31st our car starting making a loud knocking sound but the engine light did not come on so we thought maybe something got stuck on the bottom but nothing was there. On Nov 1st the oil light came on so we went to get the oil changed. On the way the check engine light came on and shortly after the knocking sound got worse. When the sound got worse the car would no longer accelerate no matter how hard I pressed the peddle. We assumed it was the battery and got a replacement but the issue didn't go away. I was able to coast to a place for an oil change but after that the problem was even worse. I was on the highway with my kids in the car when the car completely gave out, it would no longer start. When I turned the key you can hear the engine wanting to turn on bit it never does. I had it towed to a mechanic the same day and he was able to look at it today (Nov 1st). He said the motor was completely shot and the car was unusable. We are about 1200 over the warranty so the dealship will not help us. There was no previous warning that anything was wrong with the car and it was extremely dangerous for the car to give out on the highway without notice. Now we are stuck with the expense while hyu youndai does nothing about checking the check engine light. After reading other complaints that are way too similar to mine, this needs to be looked into.

For a few days prior to the incident, the car hesitated slightly from a dead stop while we accelerated. There were no warning lights from the car indicating any issue. Because it seemed odd, we made a appointment to take the car to the dealership to look into the issue. While waiting for our appointment on July 12th, 2020, merging onto the interstate, there was a failure of the transmission, such that the engine would just spin with no power going to the wheels at higher RPM's. feathering the throttle, a speed of about 45 mph could be attained on flat ground and significantly slower on hills. After limping it along to a local shop, were were told that the catalytic converter was clogged, causing it to overheat the torque converter, which had failed sending shrapnel through the transmission. They only knew this because they had to take the car apart, since even after the failure, no warning lights came on. We ended up needing a full transmission rebuild, a new torque converter and a new catalytic converter. This is a huge safety issue, especially since there was no indication from the cars warning systems that anything was wrong, even after the transmission failure. This could have lead to a very serious accident on the interstate.

When accelerating after stopping, the gas pedal will be pushed down but car will stall and not go. The engine will rev up, but the car does not move and then all of a sudden will accelerate forward. Also, when coasting in rush-hour, accelerating after a stop sign, the car will make jerking movements. It has been taken to a Hyundai dealership where they told me it is a dual-transmission so I just need to be more aggressive with it when taking off from stop light/stop sign. I know that this is not normal and most definitely needs to be revisited as there have obviously been enough complaints and has been an issue previously.

My vehicle is exhibiting issues with power. My car has stop on the hwy and has clanking noise when it gets close to 4000rpm. It's slow to speed up and sometimes stays at 50mph no matter how long my foot is on the accelerator. I've taken it in to get looked and even had a tune up and it's the same issue. In reverse it's fine but going forward that's when you can feel and hear the problems. This is a safety hazard and I don't have $5000 for a new transmission. My mechanic says it's internal issue with the power train. It needs to be recalled!

Got this car at the dealership in July last year. A few weeks before this happened you would notice a hesitation from the car to move forward when you press the gas pedal whiles driving on the road. The engine began to make loud knocking noises one morning and broke down while driving on the street. Got it towed to a Hyundai service shop and they are talking about making a "goodwill" repair which will end up costing $4800. I have read many complaints noted from the 2016 Tucson owners who experienced the same issues with their cars. This is obviously a manufacturing defect. The vehicle has been recalled before for a Tucson secondary hood latch recall campaign.

Hello, I bought a used 2016 Hyundai Tucson eco less then a month ago from autonation that had only 40,000 miles on it. Within 2 weeks of buying the vehicle, the check engine turned on for a P259F trouble code for a turbocharger position sensor that I had got from using autonation's vehicle app. Naturally, I called autonation to have my car fixed, but the engine light had gone off before I brought my in vehicle in for repairs. When I did bring my vehicle in to the dealership, they confirmed that there was a check engine light on from my turbo, but that it had gone off and that the car was functioning normally, and to go to a Hyundai dealership for a special diagnostic if the issue consisted. On the same day of getting my car back, I started noticing engine performance issues, my acceleration would be affected by 1 to 2 seconds where the car would not go, and when it would finally notice the throttle it would jump kick the car. Also the worst of all, it also cut out at one point where it did not want to give any sort of throttle at all, I needed to have my foot all the way down on the pedal to just go 30 mph. During that time I noticed that the engine would be revving high while no speed was being gained, and no check engine lights where going off either. Because of that, I was almost involved in an accident where I could not accelerate out of an intersection when making a turn. What makes me believe this is the turbo electrical problem, is that the way I got my car to accelerate normally is that I parked it and restarted it, after that it started accelerating normally, but at times the acceleration would still be affected.

I'm the original owner of a 2016 Tucson. Here are all the symptoms and issues with this vehicle: Dealer recommended replacing the catalytic converter Dec 2019 and I had the part replaced. Had an oil change on 1-26-2020 and the next week on 2-2-2020 the engine was tapping, checked the oil and discovered no oil in the engine. The low oil indicator light never came on. The car continues to burn oil. Mechanics checked car again and no leaks was discovered. And still unable to determine why this car is burning oil. Mechanic is recommending a new engine. Also, the car will not accelerate accurately and hesitates at about 45 mph. There is a clicking noise when turning the steering wheel. The dealership says that does cause any problems but the part can be replaced. The drivers door sticks have to pull on the door handle 2-3 times before the door opens. Major engine issues,
