Recalls and investigations
One recall on the engine covers the 2017 model year. A recall on the same system isn't always the same failure, so read the defect text.

Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2017 Hyundai Tucson that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs.

What owners wrote
“Knocking noise in motor and metal flakes in the oil. Called local dealership. They report no recalls for this issue.”

“Loud knocking in the engine that increases or decreases with the rpm. Metal shavings found in the oil. Appears to be same issues described as active recall for 2017 Tucsonâs, but no recall for this vin. No alerts were or have been triggered within the car. This has not been brought to a dealership out of fear of seizing the engine.”

“2017 tuscon with less than 100k miles, started making knocking sounds and unable to accerlate. The engine light came on. I go to the dealership, without any inspections he says it's a rod bearings. The 1.6T engine was retired because of the issues and they are still selling these faulty vehicles! I've only had the vehicle for 2 yrs.”
