1. "Transmission or ECU" 2. There is a lag and sometimes almost stall when accelerating from a stop. I was turning into a lane from a stop sign and the car decided to not move for 3-4 seconds after pressing accelerator. If people had come around the blind corner when that happened I would have been T boned. 3. All four people living in my house...... and our mechanic. Yes 4.No, because were not paying for something that has had a recall. 5. We inherited this car from my grandmother and she knows nothing about cars so she never thought anything was wrong. Since the day we got it, it has been doing the same thing "DCT CONTROL LOGIC UPDATE & P0128 DTC LOGIC UPDATE (RECALL 149)" #17-01-023

I have been dealing with ongoing engine performance problems for over a year. My Tucson consumes oil at an abnormal rate, and I constantly have to refill it. There is also sluggish acceleration, and the Check Engine Light has stayed on despite multiple inspections and maintenance efforts. I’ve seen hundreds of complaints about this exact issue from other Hyundai owners. I also found that an the federal safety agency investigation is ongoing, yet Hyundai continues to deny responsibility, often blaming the issue on the owner. I believe this is a safety concern and a manufacturer defect that needs to be addressed before more drivers experience full engine failure. Please investigate this further and include my VIN in any future action or recall.

The vehicle does not accelerate entering roadway, transmission replaced in 2022, catalytic convertor replaced in 2024. Several instances occurred when entering highway vehicle lost power and failed to merge safely, ultimately requiring hasty exit to roadside to avoid collision. The vehicle was purchased used but has been a safety risk since purchase date. Originally diagnosed transmission, then catalytic convertor, then knock control sensor. Engine oil is replaced more often than routine maintenance and refilled in between oil changes. Autonation Hyundai Mall of Georgia originally assisted with transmission replacement Feb 2022, catalytic convertor was replaced in Mar 2024. The vehicle has been parked for considerable time while insurance and car payments continue. In Feb 2025 my daughter was driving and was nearly rear ended when vehicle failed to accelerate, it has primarily parked since that time while exploring repairs. Car fails [XXX] enroute to game. Last quote to repair catalytic convertor was Total Automotive in Gainesville Ga. around 19 May 2025. I believe this vehicle poses a significant safety risk due to acceleration delays, all attempts to resolve have been unsuccessful.

Car started to not accelerate when pressing on gas pedal the RPMs would not raise or lower during this time it could be on a hill or on a flat surface at any type of stops whether it was a stop sign or a stoplight it didn't matter how much gas you gave the car it would not move and then it would start bouncing what I would describe as hopping the car would start jerking constantly until you released off the gas and gave it more gas until it would finally go this was happening on highways or on city streets while driving down a highway my engine made a funky sound and it turns out my engine rods blue I went to the dealership they told me my car was safe to drive I continued driving my car until it started not shifting this was 3 days after going to the dealership. I called the dealership back told them I was bringing my car to them due to the issues it was having. After several weeks the dealership told me my car needed a brand new engine and transmission due to engine rods breaking transmission went out and metal in the oil filter. Not even 6 months later my car is have the exact same issues and my dealership is not want to do anything to fix my car even with having a warranty to cover everything they fixed.

All my doors stick and sometimes I have to fight with my car to even get a door open. Also, when trying to accelerate sometimes my throttle response is slow and i will not move for a few seconds.

Over the last 5-6 years, the 2016 Tucson has experienced an acceleration issue. When making a turn after a stop, the car will not accelerate above 30 mph. The RPMs will go up to 3000-4000, but the car will not go above 30 miles per hour. This has happened 5 times. I have had my mechanic look at the car, but because it was intermittent, they could not determine the cause. The fuel pump as well as the purge solenoid have been replaced on the car. If I turn the car off and let it sit for a few minutes, the issue seems to resolve. Only once has the check engine light gone on. Because the car will not accelerate this is causing a safety issue.
