   While driving over the pass the car suddenly lost power and was running very rough. Luckily there was an exit close by that we took and the engine died on the exit. We were able to get it started and get to a parking lot where it died and would not start again. While trying to start it in the parking lot the check engine light came on. So, after a $375 tow to the nearest town the mechanic discovered a damaged spark plug and the compression test showed 0 psi. The scope showed…

   My 2018 Hyundai Santa Fe Sport (2.4L Theta II GDI, VIN [XXX], approx. 110,000 miles) has suffered a chain of engine and emissions-system failures that create a loss-of-power safety hazard. At about 80,000 miles, Hyundai replaced the original engine under warranty for excessive oil consumption, a defect Hyundai has acknowledged across the Theta II engine family. After only about 20,000 miles on that replacement engine, the catalytic converter failed and set a P0420 code. The…

   Bought this as a used vehicle with around 77k miles. The SUV was running fine for a little while until I drove onto the highway. It eventually began to bog down and there was hesitation and jumping instead of acceleration. This continued my entire trip home with the check engine light on. The car was only driven for about 300-400 miles in the time I had it. When I brought it to have an oil change, they found metal shavings in the oil. From what I’ve been reading, this has…

   The engine on this vehicle suffers from a severe oil consumption defect that was first officially reported to the authorized dealership on February 3, 2025 at approximately 90,000 miles while under the factory powertrain warranty. The vehicle completely empties its engine oil supply in under 1,000 miles of normal driving. Running entirely out of oil within such a short interval poses an imminent, extreme risk of sudden engine seizure, catastrophic mechanical failure, and…

   The Hyundai Theta engine is a bad design that has many recalls, a history of oil consumptions, and breakdowns that leave consumers in danger, on the roadside, and out of money. This engine has a design that causes worn engine components and high oil consumption causing reduced engine power, ruined spark plugs, and engine damage with no recourse as a owner. Recently, my family member had a hesitation that causes the car to run rough and display a check engine light. She was…

   I had my engine replaced in Nov 2024 due to excessive oil consumption. I was required to do an emissions update due to a recall on my car. Once the dealer did the update, it caused my check engine light to come on and now I need a new catalytic converter, which was all due to the excessive oil consumption. Hyundai dealer knows this but they are telling me I’m responsible for replacing it. It should be replaced by Hyundai not me. It was the issue with the engine.

    While driving on the highway at approximately 70 mph with a heavily loaded vehicle, my 2018 Hyundai Santa Fe Sport 2.4L suddenly lost power and entered limp mode. The check engine light flashed and diagnostic code P1326 was stored. During limp mode the engine was banging hard, almost like it was seizing and then releasing repeatedly. This is consistent with connecting rod bearing failure, not wrist pin failure. P1326 is generated by Hyundai's Knock Sensor Detection System…
