Car just went from complete cool to over heating and engine light to flash. Checked to make sure I had fluids. All full. While I had car turned off turned it back on after 15 minutes and car went straight to overheating again. Had a garage look at my car, there’s a 3 cylinder misfire on just the one side of the engine. They agree and don’t understand why this happened or how.

I have had fairly issues with overheating and have had several repairs done including: 12/29/2019 - Radiator Fan Assembly and Electric Fan Motor Replacement 10/02/2021 - Replace Thermostat and Gasket & Replace Coolant Recovery Tank 8/9/2022 - Installed Module, Control, Sensors and Fuel Filler (all done with regards to presumably fixing the overheating and RPM fluctuation while overheating) I paid $3K for the August 2022 repairs and they told me they could not replicate the issue but believe that the repairs are related to the problems I am experiencing. I use my car to drive to periodically drive to another town (60 miles away) and then to drive to the airport for work (about 25 miles). After August, I took my car on the 60 mile drive and 30 miles in, the car started overheating. I called the Ford dealership and they told me to check the radiator (it was full and slightly bubbling). The idea of driving a vehicle that is not safe (not going to make it to my destination after repairs intended to do so) is terrible. When I got back home (terrified after having to drive the same car back 60 miles later that evening), I took the car back to the same Ford dealership. After a couple of days, they told me they THINK it is the internal water pump. When I asked them if that would guarantee the fix, they said NO because no codes are showing up and there are no other signs of overheating (so it SHOULD be the internal water pump). This does not seem right to me. The car has electronic sensors everywhere and the dealership put me back on the road with a car that started to overheat within 30 miles.

First it was the alarm system it would lock me out the car. Then it was the air conditioning it would only turn on when it wanted too. Then I would press the seat cooler and it malfunctioned and I had a second degree burn on my lower back. Then the check engine light came on and it started to overheat. I pulled over turned off the ignition and the car was still running. That happened twice my mechanic would come turn the car off even by disconnecting the battery the car was still on somehow he had to disconnect another part for car to turn off. He told me not move it anymore. 15 to 20 minutes later the car was on fire and the fire department came and turned it off. I bought the car on 4/24/2021 and it was on fire on 05/27/2021.

I took my 2013 lincoln mkx for maintenance. I was told that my power transfer unit, (ptu) was defective, it is a sealed unit and being an integral part of the drive train, it needed to be changed. Vehicle was stationery. I contacted lincoln to see why an essential part should have failed. I was told there are no recalls, nothing could be done. 1.other people had similar issues. 2. The police cars were equipped with coolers so that the ptu would not overheat. 3. The cars with the ptus sold overseas were given a drain plug. 4. Ford switched the makers to a new one because of the incidents. I sent an email to nancy joy falotico, president, the lincoln motor company, not hearing I called the executive offices, I received a call from another rep. Who was responding for ms. Falotico, she said again, nothing could be done. Keep your receipts and if there should be a recall you can get reimbursement. The malfunction of this part could have catastrophic results. Lincoln motors gave the bbb an unacceptable response. 2.contacted attorney general's office of ct response not acceptable. Same response as twas sent to bbb. 3.reccommended to contact you. 4. Letter from ford tried to make it just a warranty issue. It obviously has nothing to do with warranty.

2011 lincoln mkx electrical system software recall lincoln issued a recall (10v659000) the federal safety agency campaign #11v128000 which required replacement of affected bcms may have the potential for an internal short. If an electrical short develops, an overheating condition may occur which could result in a vehicle fire. Our lincoln started to develop issues only a few weeks after purchase. The turn signal would repeatedly burn out. The dealership we purchased from replaced the bulb & housing several times with no permanent fix. After some research we found the recall notice & called lincoln directly. As it turns our the car (VIN number & all fit the criteria for the recall per ford) however lincoln refuses to fix the affected module because the car is originally from canada! We live 1 hour away form canada, so iam sure we are not the first to buy a car in the us that originated in canada. At this point we do not even feel safe driving the vehicle for fear it will catch fire. The signal & running lights burn out every 2-3 weeks. Very scary! We cannot in good faith trade the car in either with knowledge of this information. The mechanics that have looked at the vehicle stated that there is evidence of an actual fire around the turn signal housing.

Driving at night headlights started to flicker and then went out. 1st left side then right side. Solder connecting headlight assembly to electrical wiring dissolved. Per ford dealership the solder is dissolving because the electrical circuitry in the headlight assembly overheated causing the solder connection to fail. This happened three times. The first two time the dealership re-soldered the connection. The third time they had to replace the headlight assembly with a new er headlight assembly with updated internal circuitry from my conversation with the ford dealership this had happen in the higher end models of the lincolns that are a few years old. Why did I have to wait for it to happen three times before they told me it is an internal design defect of the headlight assembly. The cost of the replacement assembly for both sides is around $2,300. I got caught with this twice late at night, I originally thought it was the headlight bulbs. Fortunately, I was still relatively close to home, and not halfway into my 180 trip I was starting out on. This happened around 4 in the morning when I was driving on a rural highway without street lights. Not very pleasant driving without headlights.
