general problems of the 2008 Lincoln MKX

I am reporting a serious mechanical defect in my 2008 Lincoln Mkx involving the internal water pump. This vehicle uses the Ford 3. 5l v6 cyclone engine, where the water pump is mounted inside the engine and driven by the timing chain. My water pump failed unexpectedly, causing coolant to leak into the engine oil. This design flaw poses a serious safety risk due to potential engine failure while driving. This could lead to the engine seizing without warning, loss of power steering and braking, and increased risk of a crash. Ford and Lincoln are aware of this issue, and many owners have reported similar failures, but no recall has been issued. Repairs cost thousands of dollars and often require full engine replacement. This is a known design defect that puts drivers and passengers in danger. I urge NHTSA to investigate and mandate a recall before someone is seriously injured or worse. This failure is unpredictable, dangerous, and affects many vehicles using this engine platform.

My passenger rear door will not unlock. Tou can't open from outside or inside. My grandson got stuck. I had to have him use a didn't door to get out. If there was a accident he would have been stuck in there. It was stationary.

Had all air filters replaced and air unit replaced due to over heating but still when turn air on and on seats jumps or loses throttle and lights go off and at times seats re adjust while driving, keeps happing can't figure it out.

Takata recall: since receiving our airbag recall (over 1 year ago) we have been to our local dealership over 3 times and no parts are available to fix the recall and driving the vehicle can cause death. Local dealership stated no date for parts was given by Ford. Contacted Ford and no date given and no resolution to fix vehicle which is not drivable without the risk of death.

Takata recall we were driving down the road all of a sudden the wrench light come on and the speedometer quit working and tire pressure sensor monitor failure light came on. Then rpm picked up to 3000 was loosing power, drove 3 miles to nearest wide spot. Put vehicle in park cut engine off, let it sit , all lights went off , put it in reverse it jerked abnormally hard and when I put it in drive it would not pull out. Vehicle now will not drive forward at all. When we finally got home with our son I looked online to find that this vehicle has done this to other people. I went to you tube and typed in 2008 Lincoln Mkx and was amazed to find that others have had the same problem with this vehicle and it says its something with a speed sensors for the transmission. There are hundreds of compliants similar to mine. I feel if this were to happen to someone who was driving down the highway it could get them killed. Please look into to this and see if a recall needs done for the safety of everyone. Thanks.
