Stalling on other Sonata years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2019, 2020, 2021, 2022, 2023, 2024.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the battery (13 reports), the engine (11 reports) and the fuel pump (3 reports).
Recalls and investigations
5 recalls on the engine cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
The low pressure fuel hose that connects the low pressure fuel pump to the direct injection fuel pump may crack over time, due to heat generated within the engine compartment.
The low pressure fuel hose that connects the low pressure fuel pump to the direct injection fuel pump may crack over time due to heat generated within the engine compartment.
The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe.
Machining errors during the engine manufacturing process may cause premature bearing wear within the engine.
In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2014 Hyundai Sonata 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.
If you are servicing a vehicle with a transmission slipping concern, follow the Service Procedure shown below and perform a stall test. This TSB provides a procedure to test each clutch in the transmission.

Should you keep driving it?
This page can't tell you that. 2 of 141 reports involved a crash and 1 people were hurt. 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.
