Overheating on other MKC 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: 2015.

What this problem usually is

Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car. Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.

Is this a known problem?

The manufacturer has sent NHTSA 2 service bulletins or notices for the 2019 Lincoln MKC 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.

“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.”

Should you keep driving it?

This page can't tell you that. 0 of 54 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.
