#DoorLatch

On Wednesday, Ford Motor Co. announced two safety recalls. One is a brake line issue involving 343,900 F-150 pickups equipped with the 3.5-liter EcoBoost V6. The other relates to door latches — an obnoxiously familiar headache for the company — and encompasses a whopping 2.15 million vehicles from the 2011-15 model years.

Ford says the affected vehicles may not have had all door latches correctly replaced or replaced at all when repaired by dealerships under safety recalls 15S16 or 16S30 — both of which were done fix faulty equipment that was susceptible to failure in direct sunlight.

Apparently, the thermal threshold of the parts wasn’t all that impressive,and a few doors popped open while vehicles were in motion. While the manufacturer said it was unaware of any injuries related to the incidents, having a door randomly pop open on the motorway is universally undesirable.

Ford is going to take another whack at it.

Sajeev,

As I look outside a the terrible weather, I felt it was opportune to ask you (and the B&B) a relatively simple yet timely question about preventing car door freezing: door handles, windows, etc, during the freeze and thaw cycles that we are increasingly experiencing.

On Sunday our temperature reached a record low of – 22C but on Thursday we had driving rain and a record high of + 10C melting all the snow. Friday we are dropping to – 13C with high winds and freezing rain/sleet/snow. All of these freeze thaw cycles play havoc with our autos.

The high temperatures combined with the salt used to keep the roads less icy results in rusting. Perhaps less serious but just as frustrating are the freezing of windows, doors, door locks and door handles.

On Wednesday, Ford Motor Co. recalled 1.3 million F-150 and Super Duty pickups to fix faulty side door latches. In the affected vehicles, a frozen door latch or a bent actuation cable could result in a door that neither opens or closes — nullifying the only thing it’s responsible for.

However, the real risk comes from faulty doors that appear to be functional but latch improperly when shut. Points of entry that may appear to have shut as intended could still have latches that don’t engage with the striker effectively, allowing for a seemingly closed door to swing open suddenly while a vehicle is in motion.
