What owners wrote

“Engine has coolant intrusion at 57,000 miles. Mechanic recommends full engine replacement.”

“The head gasket has failed, leading to coolant intrusion into the number 2 cylinder. Several misfires occurred due to this. This is a known issue due to the design of the lower block, which uses a channel, thus causing a very small surface area for the head gasket between the channel and the cylinder, which accelerates wear. Spent $3,000 to fix this well-known design issue. Car at ~100k miles.”

“My car misfired, then the heat wouldn't work then started to overheat. The car is 2019 MKC 2.0L engine. Only 64k miles on it. I am the original owner. Took it to the dealership and they said the coolant has back up into the engine. I read that this has been a known issue with these engines and was never notified. It is going to cost 10k to replace this engine.”

Should you keep driving it?

This page can't tell you that. 0 of 48 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.
