Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2014 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.

Hyundai is conducting a product improvement campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs.
Hyundai has developed a new engine monitoring technology called a Knock Sensor Detection System (KSDS). The technology uses software innovations and leverages existing engine sensors to continuously monitor for symptoms that may precede an engine failure.
What owners wrote
“My truck started knock and losing power as I drove it. I took it to get serviced put the machine same is was a recall on the engine.

“I was drying my 2014 Hyundai Tucson 12/27 and the engine began knocking and the speed dramatically decreased. Now, the engine no longer works at all. I took it to the hyundai dealer and they refused to fix because it is not currently in a vehicle recall campaign (although it should be). I am also filing a complaint with the nhtsa today, which currently shows 49 similar complaints for this exact year and model.”

Should you keep driving it?
This page can't tell you that. 1 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
