I think so. I had mine right at cold mark in fall. Then a few weeks later with cold weather it was .5 inches lower. Stayed there all winter.
There have been several law firms posting here. Did you initiate the contact? Does the 2010 Ford Edge have the same issue?

Id be glad to speak with you. This just happened this weekend to me 62000 milesHi Motoarzan,
I work for a law firm in Ontario that is investigating this matter, and am wondering if you would be interested in speaking to me?
We’re do I go to find out information about this class action suit so I can be prepared if or when it happens to mine. I’m already having problems with the paint bubbling on the hood from the aluminum getting contaminated before painting. Thing is only a little more than 3 years old.
Thanks.Posted earlier in this thread, if I remember correctly - Kessler Topaz Meltzer & Check, LLP Announces A Consumer Class Action Filed Against Ford For Defective Water Pumps
I was thinking about this for awhile. What's the failure mode of the water pump? It's obvious the pump isn't weeping coolant out of the channel by the alternator as intended. I saw lots of photos of broken impellers (it is plastic BTW). And the coolant is being dumped into the engine. So is it a bearing seal leak for the pump itself?
One thing I can think of is the timing chain tensioner isn't working right or is causing the bearing/seal to prematurely wear out. Possibly due to the 5W-20 or 5W-30 oil being too thin or run too long causing it to thin out.
What if synthetic xW-40 or xW-50 was used? Would this help reduce the amount of timing chain tensioner wear/damage that might induce the pump failure?

Some of the Police Interceptor water pumps are failing at 50k miles at an earlier time than most civilian drive cycles. I doubt the coolant is becoming acidic in such a short time, if that were the case then all the other police vehicles (with external water pumps) using Dex-Cool would be spewing/leaking coolant at around the same time and mileage. This leads me to suspect the timing chain/tensioner system as this is the unique part of the transverse 3.5 water pump design.
To her defense, there's really no maintenance schedule to prevent an early water pump failure.Some of the Police Interceptor water pumps are failing at 50k miles at an earlier time than most civilian drive cycles.

My girlfriend's Grand Am GT1 had almost 210k miles and 16 years of usage before its water pump started spraying coolant all over the engine compartment (literally, slinging coolant everywhere) and it used Dex-Cool since day one (granted it is a different pump altogether and belt driven). Crown Vic were used as police cars and those water pumps weren't known to prematurely fail.But these are all metal impellers, while the Ford 3.5 uses a plastic impeller.
A co-worker has a 2011 Flex (3.5 N/A, FWD) with 111k miles and never had to replace the water pump. She doesn't seem like the person that would keep regular maintenance of her vehicle aside from oil changes.
Since the Explorer Sports are having water pump failures, 5W-30 wouldn't necessarily be the answer but the GTDI EcoBoost takes a toll on engine oil. I'm wondering if the use of a synthetic xW-40 or xW-50 would help prevent the timing chain/tensioner issues.
