2019 Hyundai Tucson Transmission Problems

The vehicle is experiencing excessive oil consumption and increasingly severe engine performance symptoms. The oil level drops rapidly between changes, but the loss is not due to external leaks. The engine burns oil internally, causing residue buildup and damage to other components — specifically the intake manifold and catalytic converter, which the dealer has now recommended replacing.

When u try and pull out in traffic the Car hesitates and kicks to pick up and go . Had a few mechanics look at it and was told it is the Torque Converter With the Vehicle only having 19,000 miles on it .it is a huge safety issue and Hyundai is saying my Tucson has no warranty on it. So what I till crash and sue Hyundai?

I was driving approx 55mph on [XXX] in my 2019 hyundai tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks.

I was driving on the highway when my vehicle started decelerating and shutting down completely. I ended up safely pulling over because it could’ve been a serious accident and called FHP they tested my car code p1326 came up I had it towed to the dealership where they assured me I had the extended warranty and that the car should be covered and I don’t have to pay out of pocket.

The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete.

I have a Hyundai Tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: [XXX] The knock sensor failing is not really what causes the safety issue.

While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road.

Car has had shaking during acceleration and a noise (rattle/knock/tapping) from the engine for last 18 months. Dealer “could not find any issues” until July 31st 2025 when the engine broke down with a P1326 code (connecting rod bearing failure) and the engine seized. Vehicle is under class action class with extended 150k 15 year warranty on engine for this concern.

On a busy highway, my car broke down. It was due to the rod bearings, specifically, the Hyundai Theta "extended warranty"/recall issue, or "recall" issue. There is currently a class action lawsuit against Hyundai.

My catalytic converter failed at roughly 70k miles (confirmed by mechanic and replaced). I have now been having transmission issues ever since, starting with the rpms jumping up on their own when trying to downshift (reproduced by mechanic) and ending with the car fully going into limp mode while in the middle of driving on the highway at speed.

The vehicle was repaired under the major engine failure recall. Took the dealer months to replace the engine and now they are reporting the transmission is bad too. The car had absolutely no issues pre engine failure leaving me stranded.

Engine failure due to connecting rods issue. Engine began to smoke while driving with no warning, had complete engine failure and had to have vehicle towed to dealership.

There is a significant issue for engine oil consumption that may cause the engines to seize up and require repairs and or replacement. To that end the vehicle purchased has a 15 year 150,000 mile extended warranty included. The vehicle is now in for additional repairs related to the same issues and verification if a new engine will be required.

I took my vehicle to my mechanic for inspection check up. My mechanic told me and supplied paperwork from their scans that the P0420 sensor in the cat converter was shot again (3x in 5 years) and needed to be replaced. The engine light had come on 3 weeks beforehand and I had it read and knew what it was.

’ve replaced the catalytic converter two times , the check engine light is on so it says I need another catalytic converter, that was in June 2024. The car was at the shop yesterday, needs catalytic converter and oil is pooling all throughout the car , fumes from the exhaust are coming back into the car which makes me physically ill.

I have to add oil to my every 2 days.. there is no leaks and I get frequent oil changes. Also acceleration to meet state limits my RPM go super high not wanting to shift.

The check engine light goes on and off every few weeks and it would stay off for a few days! The last code I had was P0420 that came up and I had a different one before that and it was for the catalytic converter! So I had already made the appointment to get it checked out and it was a faulty catalytic converter!
