2019 Hyundai Tucson POWER TRAIN,ENGINE

Engine making knocking sounds, losing power, no indication of low oil levels until very low.

Fitzgerald Countryside Hyundai - address is 27419 US Hwy 19 N, Clearwater, FL 33761 refuses to fix a recall on my unsafe car. Check engine light flashing due to code P1326 which is an issue detected by KSDS that monitors unusual engine vibrations and is designed to prevent engine damage

High oil consumption, Taken to dealer for oil consumption test, Have to drive vehicle 1000 miles , Then take vehicle back to dealership to see how many quotes of all I’ve burnt or lost recheck oil levels

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. Had recall performed for the knock sensor detection system as required by class action. Dealership first asked for most recent oil change record (provided) and than informed that Hyundai declined repairs due to full maintenance records not being submitted. Have now submitted full maintenance records to dealer and Hyundai directly since I purchased in 2023 as certified pre owned. All maintenance performed as per factory recommendations In manual. Hyundai still declining repairs without any explanation.

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.

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 former never triggered a light or produced codes, and with the latter the CEL flashed three times at the very start of the breakdown, and then went off and never came back on, despite the obvious problems the car was having.

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. They sent me to Hyundai dealer as it was under warranty with documentation. I get to Hyundai dealer tell them it needs the sensor for inspection and an investigation for oil leaking from back of the engine. I also told them I was adding 2-3 quarts of oil between oil changes. They told me my mechanic over filled oil by .5 quarts and that's why the engine leaked. They investigated after I disputed by saying an oil change had been performed the day I brought it to them and found a bad head gasket, fuel pump seal, and oil pan seal. They charged my extended warranty for those repairs, shut off engine light for cat converter sensor without replacing it, and made me do an oil consumption test of 1000 miles. Car was still not inspected at this point. After 35 miles check engine light comes back on. Cat converter sensor P0420. I take it back in. They tell me they won't replace it until the oil consumption test is done because they need to know if oil is coming through the exhaust pipes (it was). I complete the test and go in. They tell me engine is burning .5 quarts of oil/1000 miles which is acceptable and as long as I complete oil changes every 5000 miles I will be fine. They then tell me if I want sensor replaced I'm 800 miles over warranty so I have to pay $2400 to replace. Called corporate they're only willing to cover half the repair as "good will" for the cat converter and was quoted $1300 by the dealer in question. Almost a month and still not fixed and still can't get car inspected because the check engine light is tripped by the P0420 sensor in the cat converter. It's the only vehicle my family has. I'm forced to pay to have transportation.

Knock sensor keeps throwing codes, the car will not accelerate over 20mph and under 2000 rpms

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. Again no leaks and have checked so there is good transmission fluid in it

- replaced catalytic convertor twice - Check engine light on , needs another catalytic convertor - Exhaust fumes are coming back into my car through the AC vents , I’ve had to pull over due to being nauseas and extremely dizzy. - The dealership will not answer my phone calls , but will answer another phone because I have called from another phone and they picked up immediately - Was told from a service advisor that they would not help me “ unless the car blew up “ - My car did recently ,8/8/24, shake aggressively, the check engine light flicked rapidly and a strong puff of fumes came through my car - They will not help me because they stated that my rod bearings are not rotted therefore I do not qualify for assistance and everything would come out of pocket , the engine replacement , the catalytic convertor due to me being a few thousand miles outside of my 100,000 warranty. - I have the invoice stating oil is leaking profusely out of my engine - I was told within the last 2 weeks that if my car was to actually seize , Hyundai is not responsible bc when they kept telling me to bring my car in , they kept diagnosing it so they quoted me at about $5k to fix everything.

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. What the dealership told me would take 2 days has now been almost a month and still counting. I’ve had 3 denials for engine replacement due to being outside of warranty with Hyundai even though I have the extended warranty. The dealership has sent pictures and spoke with my case manager at Hyundai to confirm that the engine failure was due to the bent connecting rod bearing that is again covered under warranty. They came back and said other codes populated showing the cause was not the rod bearing but that has to be false. One of the other codes was regarding coolant and I’ve never had any issues with my car overheating or anything prior to my engine shutting down on the highway. I never had any flashing lights or warning signals on my dashboard. This was very unexpected and I refuse to pay for a repair that I didn’t cause especially when this is consistent with Hyundai and their engines. This is a 2019 I should not have any issues. I need a solution quick

I’m traveling for work and I have only had to car 11 months. I have 52,000 miles on it and today tracking home my car engine light came on and my car wouldn’t shift through the hills in Missouri. It got so bad after 1 mile of the engine light flashing at me that I had to stop in a construction highway with one lane and stop all traffic to let my car cool down for almost 15 minutes and I started it up and it would not go over 10 miles a hour. With my flashers on I got off the next exit and ran a diagnostic at O’riley’s in St. James Missouri. My codes are reading CAMSHAFT IGNITION CONTROL (P000B) and IGNITION CONTROL MODULE COMBUSTION QUALITY INPUT SIGNAL (P1326)

I bought my Hyundai Tucson 2019 brand new, it has 38000 miles on it still under warranty in the past two months engine light came on three different times brought it back to two different dealership still have same problem, my car still in dealership parking lots waiting for three different parts from Hyundai, my car is not safe to drive and I feel there are cover up about engine problem with the Hyundai Tucson 2019, please I need help to to solve this problem thank you

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.

Purchased the vehicle in June 2021 only had 1 previous owner. The dealership stated it was a pre-owned certified used vehicle that had just been inspected and service. Within the first month I had to take it back for multiple issues most recently the catalytic converter to be replaced and the Engine. I haven't even owned it let alone driven it long or far enough for either of these parts to need service or have failed. It's not even time for my first oil change that how low the mileage is that I've put on it. The dealership originally told me they never head about the complaints regarding the engine now they are trying to stiff me on selling me a lemon by charging me 3000 and telling me Hyundai isn't willing to cover the repairs. If this is a known issue which is seems to be a recall should now be issued.

SPORADIC HESITATION WHEN STARTING FROM A COMPLETE STOP. THIS HAS HAPPENED TO ME ABOUT 15 TIMES, USUALLY WHEN PULLING OUT INTO TRAFFIC. THE CAR HAS 4000 MILES AND HAS BEEN IN SERVICE ABOUT 6 MONTHS. THE SERVICE MANAGER.STATED THEY HAVE NO OTHER COMPLAINTS BUT IS PROBABLY DUE TO THE "SMART" TRANSMISSION ADAPTING TO DIFFERENT DRIVERS. I UNDERSTAND THAT THERE WAS A RECALL FOR 41,000 2017 TUSCONS FOR THE SAME ISSUE.
