general problems of the 2008 Lincoln MKZ

Vehicle is awd, part is transfer case/power transfer unit. Many issues from customers online and what was marketed as a lifetime part was changed to maintenance at 30,000 miles since the amount of gear oil is minuscule and the heat this part has to contend with is extreme due to location. Car becomes undriveable very quickly and is very dangerous. A leak began and due to small amount of oil it starts to grind, jerk and tires won’t move very rapidly. Extremely dangerous! instead of a change it should be a recall. This part is also about $1600 alone which means Ford is making money on this to top it off. The mechanic said it was starting to melt the parts and could have been a fire if I didn’t drive it right over.

I experienced unintended acceleration upon entering a highway. The vehicle accelerated normally in first gear, but upon shifting into second gear, acceleration exceeded pedal input, as though the cruise control 'resume' function had activated. Acceleration continued with my foot completely off the accelerator pedal and with full brake application. The event stopped when I kicked the accelerator pedal, suddenly, to full deflection, and engine operation returned to normal. I experienced three separate occurrences of this problem within a few hours. No codes were generated to activate the 'check engine' light, or any other warning light. Cruise control was off at the time of the events.

Check engine light went on . . Took to tech . . Timing issues . . Further examination reveled water pump leaking, timing chain stretched on one side . . Result required water pump replacement, timing chain replacement, replacement of right bank phaser and secondary chain and tentioner, replaced upper chain guides, replaced crank/sprocket. Total cost of repairs $2775. 23 . . Mileage 88245 . . Detailed invoice from repair shop is available.

My car keeps running hot and the antifreeze disappears when you poor it in also the rpm good slow then goes fast then cuts off.
