Carry handle, shell, base
My husband secured our infant into the car seat and attached the seat to the base installed in the car. He then drove our child. When he removed the car seat it was discovered the right side of the seat (when facing) was not clicked in and could be lifted up. When he removed the seat he noticed the clip on the inside of the shell, that connects to the base, was completely missing meaning he had been driving our child only partially secured. When we turned the car seat to take a picture the retractable clip on the outside of the same portion fell out.

I am reporting a serious intermittent transmission and loss-of-propulsion problem with my 2021 Lincoln Navigator, VIN 5LMJJ3LT6MEL05416.

I purchased this 2021 Lincoln Navigator L Black Label used on March 22, 2024 with approximately 42,726mi.

This is our primary family vehicle and routinely transports our three young children. The transmission hesitates, slips, skips gears, bangs into gear, and frequently delays engagement before suddenly surging forward. Engine RPM increases without corresponding acceleration.
