2017 Lincoln Mkc

My 2017 Lincoln MKC has engine coolant leaking in to the #4 cylinder. On start-up the engine runs rough, and the check engine light is on. LINCOLN/FORD has a Technical Service Bulletin #22-2229 covering this issue. I believe this is a common problem involving a large number of these engines. LICOLN/FORD will not pay for any replacement costs. I have spent $1414.08 in an attempt to repair this problem. I believe this also causes my car not to be able to pass the Ohio E-Check.

I was told by my Lincoln dealer that I need to replace the engine on my 2017 MKC. This is due to coolant intrusion issue that seems to be a very common problem with this model. I'm really disappointed, it's a very costly repair ($10,000 +) I only had 85,000 on the car. I was driving on a highway and the car completely shut down. They said the only repair is an engine replacement and are not willing to assist in the costs. The check engine light came on when the engine seized.

The contact owns a 2017 Lincoln MKC. The contact stated that upon starting the vehicle, the check engine warning light illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the engine was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

I took my vehicle to Rainbow Muffler and Brake due to my engine light on. I was told I had an Evap leak and it may just be my gas cap. I don’t have a gas cap. They turned the light off and it stayed off for a while. A few months later I took it in and was told to do a smoke test. Smoke test showed I need a purge valve ($214 for part from dealer) and Rainbow charged $105 to install. A few weeks later light returns, I take it back to Rainbow. I’m told a tune up $$250. A few weeks later light comes back on. I’m told I needed coils $325. A few weeks later light is back on. I immediately called Rainbow to be told, Lincoln knows there a defect but they aren’t acknowledging it. I filed a complaint with The BBB and my States Attorney General Office.

The contact owns a 2017 Lincoln MKC. The contact stated while driving at an undisclosed speed, the check engine warning light and the #4 coil failure indicator warning light illuminated. The vehicle was taken to an independent mechanic and coil #2 was switched with coil #4; however, the failure reoccurred. The independent mechanic reset the codes however, the check engine warning light illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,000.

Within 4 months, I’ve spent $12k on transmission replacement (refurb.) (Metallics in the fluid), Fuel injectors, etc. The check engine light is still on…Now Im told that coolant is leaking into my engine, and the engine needs replaced! (Coolant intrusion) Another $9k for parts and labor! i just paid the car off! Ive kept up with repairs and service! Ive done everything the dealer has suggested…except replace the engine! I’m still recovering from the cost of the transmission! The 2017 Lincoln MKC with a 2.0L EcoBoost engine has a known defect where coolant leaks into the engine cylinders, often causing misfires, overheating, or engine failure. This issue, linked to faulty engine block and cylinder head design, typically requires engine replacement ($5,000-$9,500). Ford issued TSB 22-2229 but no recall. A class-action lawsuit is ongoing. Check warranty status; report to NHTSA.

August of 2024 I took my vehicle to Island Street Automotive in Stoughton Mass because my engine light kept going off and off. The test showed the cylinder one misfire. They change the spark plugs and cylinder. However, I ended up taking the vehicle back 3 times for the same issue and experienced the same results. By now the check engine light was on all the time. I then realized a week or so later that the coolant was empty. For the next couple of weeks I continued replacing the coolant and had an auto shop look to see where the coolant could be going but they could not figure it out. There wasn't any leaking out of the vehicle. Soon my vehicle would begin shaking at the start up with the engine light blinking and then it would go solid. I decided to take the vehicle to Herb Chambers Lincoln of Norwood where I purchased the vehicle. They never mentioned that there was a bulletin out on this vehicle when I purchased it. It took them 3 days to diagnose. I was told the engine had to be replaced and needed a long block assembly. The charge would have been $8,634.31 plus tax. I called CarShield to put in the claim and they denied it because they found a bulletin out on the engine and stated it was a manufacturers error so they would not honor the claim. I called Lincoln directly and spoke about this issue but they blew me off and said there were no programs to help me pay for the cost of fixing the problem. I reluctantly chose to take the vehicle to North End Motors in Canton. They came up with the same conclusion. The engine was built with an open block and they needed to replace it with a closed block engine because the coolant was leaking into the oil. The charge was $7,494.72 plus tax, less than Herb Chambers. I chose to have the vehicle repaired with much anguish. I was not responsible for the issue with this vehicle but had to pay the astronomical cost. Thank you for reading.

I have a recurring coolant intrusion problem. Available for inspection. Risk of engine seizing up and running hot. The problem has been identified by a licensed mechanic. The vehicle component has not been inspected by manufactured however this is a known issue by Ford. Check engine light, misfire of cylinder #4 (P0304) and coolant inside cylinder.
