Filed Oct 14, 2026 · Engine, Transmission · 90,502 miles · LA

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at 65 MPH, the vehicle unexpectedly stalled and was unable to exceed 30 MPH. The contact pulled the vehicle over to the shoulder of the road, and the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed that the transmission failed and oil contaminated the catalytic converter, causing the catalytic converter to fail and require replacement. The transmission was repaired by the dealer, and the catalytic converter was replaced by an independent repair facility. The contact subsequently observed continued oil loss following the repairs. The vehicle was returned to the dealer, where it was diagnosed that the exhaust manifold headers failed and required replacement. The vehicle was not repaired. The contact requested and received a complete diagnostic report from the dealer. The failure mileage was approximately 90,502.

I am submitting a complaint regarding a 2017 Hyundai Tucson Ultimate AWD equipped with the 1.6L Turbo Gamma GDI engine. My vehicle currently has approximately 127,000 miles and has experienced sudden engine knocking consistent with rod bearing failure and/or catastrophic internal engine damage. The vehicle has been properly maintained, including regular oil changes. However, the engine began consuming excessive oil without warning. Upon inspection by an independent repair facility, the engine was found to have extremely low oil levels despite being within the normal oil change interval. After refilling the oil, the engine continued making severe knocking noises, and the repair facility advised that the engine is likely non-repairable and requires replacement. This failure appears materially similar to the rod bearing and engine failure issues already widely documented in Hyundai/Kia engine defect investigations and class action settlements involving related Gamma and GDI engine platforms. I have learned that Hyundai extended warranties for certain vehicles with similar engine defects up to 15 years/150,000 miles; however, my specific Tucson trim/engine configuration does not appear included despite experiencing the same type of failure. This vehicle has also previously required major drivetrain repairs under warranty, including two transmission replacements and turbocharger replacement. My concern is both financial and safety-related. A sudden engine failure or seizure while driving could create a serious roadway hazard and risk of loss of power in traffic. Additionally, Hyundai dealerships have advised that replacement engines for this vehicle are no longer readily available. I believe Hyundai should further investigate whether the 2017 Tucson 1.6T Gamma GDI engine should be included in existing engine defect warranty extensions and/or recalls.

The vehicle has a transmission (powertrain) malfunction that first appeared in July 2025, a few weeks after I purchased the vehicle and after the warranty had expired. At the time the issue began, the vehicle had well under 80,000 miles. The transmission slips, fails to properly engage, and cannot provide sufficient power, particularly when accelerating or driving uphill. The vehicle struggles to move forward and behaves unpredictably during normal driving conditions. This defect has put my safety and the safety of others at risk. On one occasion, the transmission failed while I was driving and I became stuck in the middle of an intersection, unable to accelerate, creating a serious traffic hazard. The issue has been reproduced consistently and has persisted despite repeated transmission fluid services. Multiple mechanics have inspected the vehicle and have indicated that the problem is not due to lack of maintenance, but instead is likely caused by the transmission not being properly filled with transmission fluid at the time of manufacture. Despite servicing, the problem continues, indicating an internal or manufacturing-related defect. I have also been in contact with multiple owners of the same make and model vehicle who report the same transmission failure, suggesting this is a widespread issue rather than an isolated incident.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at various speeds or accelerating from idle, there was a knocking sound coming from the engine. While accelerating from idle, the vehicle failed to exceed 30 MPH, requiring that the driver slowly accelerate and gradually increase the speed. No warning lights were illuminated. The vehicle was taken to a certified mechanic who diagnosed the vehicle with transmission failure. The mechanic replaced the brakes and tires. The vehicle was then taken to the dealer, who diagnosed failures with the muffler assembly and catalytic converter related to the failure to accelerate. The failure persisted, and the vehicle was returned to the dealer, who confirmed the noises coming from the engine while the accelerator pedal was depressed, with a burning odor, and oil issues. After five visits to the dealer, an oil leak from the drain plug was determined. The drain plug and oil pan were replaced a year and six months later. The vehicle continued to fail to accelerate properly, making it difficult to drive uphill. The vehicle was taken to another dealer, Niagara Hyundai of Grand Island (1910 Alvin Rd, Grand Island, NY 14072), who confirmed that the vehicle was not safe to drive. The catalytic converter was replaced again but the failure persisted, and there was no engine oil in the vehicle. While driving 65 MPH, the vehicle started shaking. The contact pulled over to the side of the road and waited approximately 10–15 minutes before continuing to drive at 50 MPH. The contact inspected the vehicle and noticed that the engine was hot. The vehicle was towed back to the second dealer, who performed an oil consumption test requiring the contact to drive 1,000 miles. The test determined the engine oil level was extremely low. The dealer suggested a chamber cleaning, but the request was still pending. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 63,000.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate, the transmission failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact stated that while driving approximately 25-30 MPH, the vehicle was making an abnormal rattling and knocking sound that was coming from the engine while accelerating. The transmission was shaking continuously while driving at 10 MPH. The vehicle was taken to the local dealer, where it was diagnosed with camshaft and engine failure and needed a cam finish over an advanced timing system overhaul. The contact was informed that the camshaft, CVT, timing chain and tensioner, front valve cover and valve cover gasket, turbocharger, turbocharger gasket, and turbocharger lines needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 92,000.

The transmission failed, and it's only at 70k. This was only diagnosed AFTER being told that my dual clutch was faulty. I had that replaced, only to be told that my actuator was faulty and NOT the clutch, after haviing paid for the replacement. Now, the vehicle will barely move with rpms through the roof. So not only was Ithe vehicle misdiagnosed TWICE, the cost of repairs was sky high! This could have been avoided. I contacted the dealerships, at they advised that they did everything as hyundai instructed them. Well, hyundai was wrong, and now my vehicle doesn't even work.

The engine is failing. Our vehicle continues to experience tremendous oil consumption and it's all of a sudden gone into "limp mode" where we lose engine power even after the knock sensor recall update was performed. No check engine lights, no indication of what's happening and it just loses power on the highway as well as city streets. It's a danger to everyone around us and it's a danger for us as we try to drive the vehicle. The dealer / Hyundai had us do 2 oil consumption tests but would not do anything to fix the issue. They informed us they needed to replace the engine after the first oil consumption but then they backed off of that and didn't fix the issue. It’s just gotten worse. We also had a transmission service done and they said the transmission looked fine. We took it in for a diagnostic just after this as the power issue began in "limp mode" where we lose engine power. They are trying to say it needs a new transmission but with the known issues with the Hyundai oil consumption and engine issues where the vehicles go into power loss / limp mode, we’re reporting this issue for our safety and the safety of the community as it’s unsafe to drive this care. We hope you will push Hyundai to do a recall for the engine not just for us but for all Hyundai Owners who are dealing with the same issue.

The transmission in my vehicle failed while driving and the car completely shut off while driving. Less than 4 months after replacing the transmission with a brand new transmission, the engine failed while driving on the highway. The engine started sputtering, then it started smoking, then the car stalled.

The problem began in mid to late April 2024 with the Tucson shuddering in the driveway while moving forward slowly. This vehicle has a 1.6L turbo with a dual clutch transmission. The mileage was around 96,000 miles. Once on the road, it ran fine. Approximately a month later the check engine light came on and it began hesitating upon acceleration. It would change to the next gear, accelerate and slam me against the seat! Whenever I try to accelerate too fast, it hesitates and loses power until it "catches" and starts speeding up. This is very dangerous especially when accelerating from a complete stop or after a turn. It also has trouble going up a hill and has actually died out 3 times while attempting to go uphill at a low speed. I am the second owner and it is out of warranty. I have contacted the local Hyundai dealer but their shop does not have a very good reputation and is always backed up for 3+ weeks. They also charge $230 or more to hook up their code reader!! I've already taken it to 2 other shops where that was done at no charge. The code was P073F - Unable to engage gear 1. Of course the only option I've been given is to replace the transmission for $3000 or have it rebuilt for $4100. This problem makes it very dangerous to continue driving it. I get the oil changed every 5000 miles. Of course it's almost paid for but I'm afraid if I try to trade it in I'll be lucky to even get enough to pay it off. I have been endlessly researching this online for recalls, updates or remedies. I want to know if replacing the entire transmission is the only option or is it a component of the transmission or a computer module that is the cause. How do I know the new transmission won't do the same thing?

Since I was notified of this recall on November 16, 2021, I have diligently followed the instructions provided, and my vehicle has been taken to a Hyundai service center for inspection and necessary repairs. However, I am deeply disappointed and concerned that despite the recall and subsequent corrective actions, my vehicle has continued to experience persistent issues related to the engine. I have experienced several engine problems, including repeated transmission replacements (twice) and dual-clutch replacements (three times), which have had a significant impact on the overall performance and safety of my vehicle. The frequency of these issues and the potential consequences, including engine stalling and increased risk of accidents, are alarming. I understand that Hyundai has taken measures to address the recall issue, but it appears that the corrective actions have not resolved the problem in my vehicle. Given the seriousness of the engine-related concerns outlined in the recall, I strongly believe that my vehicle's issues should be thoroughly investigated, and the necessary steps should be taken to ensure my safety and reliability.

2022-1-09 Left the house to run errands and noticed the car seemed sluggish when I stepped on the gas to accelerate. I'd actually felt like this may have been happening for some time but it is a "Sport" and it always felt a little funky when you accelerrated. It was blistery cold so my initial thought was I left too quickly and the vehicle maybe needed time to warm up. It felt like the engine didn't either seem to be shifting to a higher gear, or getting enough power to accelerate which was very concerning as this happened as I pulled out onto a busier road, yet couldn't accelerate. I made it to my first stop but called my husband to express concern something seems off with the vehicle. I told him I would likely skip my errands and come home for him to take a look. After my stop, I started the Tucson up to head home - and now the check engine light came on (solid)! Apparently flashing check engine is more serious? I was able to make the drive home to unload groceries but the whole ride home I couldn't accelerate properly so it was a scary drive home, I drove slowly on backroads and used my flashers to get home safely. We immediately called the Hyundai dealer near us which closed. Called four times the next am as we needed whatever was going on fixed quickly. Once the vehicle was at the dealer, we learned it had complete transmission failure. Thankfully it appears this is under warranty. It is STILL at the dealer as it needed to get an inspector to come out to confirm it was transmission failure (which has now been confirmed 10 days later).
