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 4 service bulletins or notices for the 2017 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.

What owners wrote

“For the last 17,000 miles, the engine light has been on. We got it checked out and there is coolant and cylinder three we change the cylinder thought it was a misfire, but the problem keeps occurring and we found out information that those engines are bad.”

“My engine kept misfiring upon starting and not accelerating while I was driving it. A coolant leak into the cylinder caused the engine to malfunction. I had to replace the entire engine block which cost over $7,000.00. The Ford repairman & service center told me that Ford had issued a service bulletin regarding this issue but then refused to pay for the engine damage. I only have 70K miles on the Lincoln.”

“I don’t have the eco boost engine so they told me my car is NOT in the TSB even though I was just told that I need a new engine due to coolant intrusion. I have a ford engine with a defect that caused the problem!! Only MKC’s with eco boost are included. How many people with these ford engines are affected but not included??”

Should you keep driving it?

This page can't tell you that. 1 of 85 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.
