My 2016 Lincoln MKC with a 2.0L EcoBoost engine experienced coolant intrusion into cylinder 3, leading to engine misfire and check engine light to turn on. The dealership confirmed the issue for $176.55 and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at 98,000 miles. Two weeks before this, the check engine light illuminated and we took it to a repair shop where we paid $628 to repair the purge valve and fuel pressure sensor, while it was most likely this coolant intrusion both times! Ford and Lincoln (including concierge) have refused any assistance in this matter. The local dealership has also said that they cannot help us with any of the cost. I've found this to be a very well documented problem/engine design failure, Including HTSA ID Number: 10162062 Manufacturer Communication Number: TSB 19-2172 entitled Components: ENGINE AND ENGINE COOLING The TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. In addition, this appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2.0L EcoBoost engine, including the Lincoln MKC and MKZ. I believe this is a widespread design defect and request the federal safety agency’s investigation to ensure proper manufacturer accountability. I am so thankful that this car does not belong to one of my daughters as it poses a severe safety hazard on the road and it is going to be a huge financial setback that we may not recover from.

When driving you could smell fumes, it would jerk, and kick in and out of gear and would have no heat. Coolant was always low with no visible leaks to the mechanic.

The contact owns a 2016 Lincoln MKC. The contact stated that while starting the vehicle, the vehicle was shaking, and the check engine warning light was intermittently illuminated. The contact stated that her brother had replaced the spark plugs and ignition coils. The vehicle was taken to the dealer, who determined that there was coolant intrusion into the engine. The contact was informed that the spark plugs and coils needed to be replaced with OEM parts, and the turbocharger, purge valve, vacuum line, long block, and fuel pressure sensor needed to be replaced. The contact stated that her nephew replaced the spark plugs and ignition coils with OEM parts, and AAMCO replaced the fuel pressure sensor; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to report the failure to the federal safety agency Hotline. The failure mileage was approximately 158,000.

At 85,000 miles I was experiencing a grinding noise coming from my front end when making sharp turns to left or right. Took car to my mechanic immediately for diagnosis. They found the motor mounts and rear differential is binding and close to failure. My mechanic contacted FOMOCO to see about a replacement for the rear differential and was told that there were not any available due to a REDESIGN of the product. He was asked to check back in two weeks! Two weeks w/o my transportation! I replaced the motor mounts, (85Kmi?) After researching on line, several ford & lincoln sites the problems I am experiencing are not unique or infrequent on Lincolns and ford Edges. It would seem to me that these problems are frequent enough to have the manufacturer ininitiate a recall on these products! My mechanic also works on our Sherriff department vehicles and their Ford Edge units are experiencing same problems. I would hope these problems will initiate an investigation into this matter!

While driving a short distance to work, my 2016 MKC check engine light came on. The previous week I noticed that the engine hesitated slightly when it first started, but it drove normally. However, when the light came on, my husband took the vehicle to the dealership where we bought it in Dec 2019. We were shocked when we were told this was a very common problem with this type of engine, a 2.0 eco boost, and that the engine would have to be replaced due to coolant intrusion, at the cost of $9300! The vehicle only has 57,000 miles on it and has always been maintained at Prater Ford Lincoln in Calhoun GA. After some research I've found this to be a very well documented problem/engine design failure. Ford and Lincoln have refused any assistance in this matter. The local dealership where we purchased it has told us they won't provide any assistance either. The vehicle is currently in the shop, and the engine is being replaced. It was supposed to be completed 5 days ago. Why hasn't there been a recall? Even though there were no deaths or injuries in my case as well as the others on this site, the financial burden is immense! Since this is such a well-documented problem, there should be a recall on the affected engines, or at the very least some assistance should be provided by Ford and/or Lincoln to the unfortunate owners of these vehicles. Thank you.
