2018 LINCOLN MKZ — Problems, Recalls & Safety Data

The car had an internal transmission failure and caused most of the transmission fluid to leak out between inspections. Upon removing the cv axle on driver’s side, the seal was fine and replaced along with cv axle. The fluid drained and was only about half a liter (needs about 4.5L normally). After servicing the transmission fluid, the dealership did their assessment and came to the following conclusion. “ Good Afternoon Sir We found the transmission system requires replacement due to an internal fault, including damage to the transfer shaft and bearings, with potential additional internal damage. Replacing the transmission can help restore smooth gear shifting and overall drivetrain functionality. To replace the transmission, you are looking at $9000.00 out the door. My apology on taking much longer to diagnose this properly. If you have any other questions please let me know. ” The drastic transmission failure which makes noises and engages and disengages while on cruise control shows the failure internally. Many metal pieces were found among the fluid when drained. This could and still can easily leave someone on the middle of the road with no time to drive to the shoulder. Car still has less than 100k miles with the severe transmission failure and the fluid leak which occurred prior to the transmission making noise. Essentially, the internal components caused the leak which the caused even more damage. I’m quoted $9,000 for the repair which occurred really early in the car’s life. I do a lot of longer trips away from home and can easily be left stranded in the middle of nowhere or even cause huge accidents when in heavy fast moving traffic if I lose drivability or if metal components fly off. The cv axle moves in and out of the transaxle side meaning the shaft can pop off as well.

Car only has 97K miles and the transmission fluid has been leaking for some time causing loud noises from the transmission which took time to locate. The transmission leaked fluid and only had about half a liter of fluid when it should be around 4.5 liters. The fluid leaked from the transmission on the driver cv axle seal. The car shows no lights on dash of any kind. I discovered the leak after the noises were really bad while driving one day. I put the car on my ramps and got under and discovered the driver cv axle damaged and looked like electrical tape was jammed in the cv axle near the transfer case/transmission. Upon closer inspection the leak of transmission fluid was even more obvious. There is no dip stick for the transmission so I decided to drain and see and there is evidence of only about half a liter of fluid. The fluid is black and full of metal particles. This is concerning because the depth of damage is unknown until the car is repaired; this repair would include a new seal, cv axle and fluid replacement. There is no way to know what internal damage was done and this was such a short period of time. Periodic inspections are conducted on the vehicle when oil changed are completed. This can easily lead to transmission failure and the risk is exponential due to it happening regardless of where you are on the road with the unknown weather and road conditions. Miles reflected is when the leak was discovered after the noises. 97,839 miles.

Wheel lug nuts get swollen due to the material used causing problems when the wheels need to be removed. I was lucky to not be in an emergency situation needing to change a wheel out. This could have easily happened and I would have been unable to change a wheel on the side of the road. I went to Costco to get my tires changed and they refused to take the wheels off because the wheel lug nuts were ALL swollen and could cause issues on removal or/and installation. They were afraid of stripping the hardware during removal or being unable to torque to spec during installation. The replacement of the wheel lug nuts with parts that wont recreate the problem was about $90 and taking an extra day for the tire replacement appointment plus me replacing it on my own saved on labor.

Check engine light came on. Error code 0302 and 0316 on ODB at dealer. Was advised that engine needed to be replaced due to coolant intrusion into cylinder 2 which cause the vehicle to overheat. Engine has 3200 miles on it. Safety hazard due to engine seizing at high speed and causing an accident due to loss of power. Also possible engine fire due to loss of coolant/overheating.

Coolant Intrusion of Cylinder 3, car has less than 50,000 miles total and has been very well taken care of. Has had over a gallon of coolant added within the month of Aug
