The internal water pump failed, dumping a half gallon of antifreeze into the engine oil. This caused the engine to suddenly stall and lose all power while driving in the middle of active traffic, creating a severe crash hazard .
2016 Lincoln MKX has stalled numerous times. We left home and had driven about a mile in our subdivision when I slowed for and stopped at stop sign. The engine shuddered and shook, engine revolutions slowed down. Sped up, slowed down and engine quit. The message, "full accessory power active' displayed on the dash and my wife got a pad and pencil and copied it down for me. This was the second time that has happened and evidently was the same message displayed when the engine quit while we were on vacation in new orleans. Checked the internet and found several instances to this happening due to a computer glitch. Ford has known about this problem for some time. Do we have to get killed before Ford corrects their faulty computers? …
When you hit the gas pedal you lose all acceleration. You have to drift to a complete stop, turn the car off and then restart it. Have almost been hit multiple times and once on the highway traveling about 50 MPH. Thankfully traffic was not heavy and I was able to get my car stopped and restarted before the possibility of someone running into us. There was no shoulder to pull off on because of construction. It was terrifying. It happens randomly and there is no warning as to when. A vehicle in this condition is not safe to drive and Lincoln seems to not know what the problem is so they send people home in their defective vehicles because as they say they can't get the problem to duplicate so they told me that there is nothing wrong with my car and sent me home now twice. Trust me there is something wrong with my car and many others and it is a huge safety hazard!!!
Car was in motion at 65mph on a 4 lane freeway traveling in lane 2 or 3. It made a loud thud and the wrench icon appeared on the dashboard. At the same time, the gas pedal no longer provided acceleration and the only thing I could do was coast to a stop, while maneuvering the vehicle to the shoulder. After stopping I restarted the car and it functioned perfectly fine. The wrench light was no longer illuminated. Two months later it happened again while in a forward motion on city streets...made a loud thud, the wrench icon appeared. I was at the west side of a 4 lane intersection and barely had enough power to coast through the intersection and pull over on the east side. After shutting the car off, it started up fine again. I am afraid to drive it now
Entering I-294 express ramp, vehicle was not accelerating beyond 40mph. then as I entered highway it shut down completely. I coasted to the right shoulder. The dash displayed a "low oil pressure" alert. So I did not attempt to restart the car. When I had it towed home, I checked the oil level and it was full. Nothing like this happened before. The vehicle is almost 12 years old with 167,000 miles. Had this happened in traffic on the expy, I could have been creamed by other cars or a truck. I am going to the dealer today to investigate but this seems like an anomaly where the engine shuts down because the computer thinks there is a catastrophic failure that is not really happening.
I was driving down 4 lane divided highway in florida and this time of year there are many citrus hauling semis on the road in fact three or four directly behind me during this occurrence. My vehicle was driving then suddenly without warning started to lose power. Engine was still running but vehicle would not respond while traffic barreling down on me during noon traffic. I had no other choice but to steer off. Had to restart engine and still not responding properly. Finally able to make it into dealership where we were told this vehicle had no recalls and they didn't have time to check. This had happened roughly six times in last six months vehicle has only 42000 miles on it I am unsure of what the proximate cause was please help
We saw something leaking onto our driveway from inside the garage a couple weeks ago. I verified it was leaking from underneath the engine area of my car but didn't think anything else about it. A week later I went somewhere and was gone about an hour and came back and parked in the garage. I came back into the garage maybe a half hour later and it smelled like gas. I looked and noticed it dripping under the engine area again. I took my car to a shop (QualTech Automotive 620 in Austin, TX) and they called me today and said there was a fuel leak. They think it is by the rollover valve. I have not seen any pictures of this. They stated the only way to fix it is to replace the entire fuel tank. $$$$ There were no check engine lights or any other warnings to notify me of this issue. …
Problems with the electronic throttle body (etb). When driving, there is an extreme, sudden and dangerous loss of power. At the same time, Ford's infamous "wrench warning light' for this problem comes on and the car enters into the 'limp home mode'. This is the same problem that Ford / Lincoln is having in which the NHTSA had opened an investigation in feb. 2013 after thousands of Ford / Lincoln owners complained of the same issue I am currently having, then closed it after Ford agreed to 'fix 1,600,000 cars that "limped home"'. My research shows that Ford claims that customer satisfaction program 16b23 has been issued. However, when I contacted Lincoln hq, they stated that since NHTSA has closed this investigation, they are not willing to include my VIN with this reported problem. This problem is getting worse as well. …
