How long since you had driven the vehicle? For how many miles. What engine? Do you have S/S? Do you have any non oem items connected? You also might check the 3G board for similar posts.
I drove the vehicle on 12/31/2020 and parked it in my driveway late that afternoon. The total mileage is 3,224, since August 2020, when I purchased the vehicle. Engine type is 99Z (I think), FWD only. I did not attempt to operate the vehicle on 1/1/2021. However on the morning of 1/2/2021, the battery was apparently dead. I had it "jumped" and drove it for about 20 minutes. About an hour later, dead battery, again. My VIN# 1FMCU0DZ1LUB70953. I'm not sure what S/S means. Can that be determined in my VIN #? The only NON-OEM items in or on the vehicle are Weather Tech floor mats. I am not familiar with the 3G board.
S/S is referring to the stop/start system. If that is not working it is normally because there is a problem with the battery not charged fully or not retaining it's charge.
2020 Ford Escape Hybrids have a 2.5L Atkinson cycle engine.
More specifically: do you have the 2.5 hybrid, the 1.5 liter ecoboost, or the 2.0 ecoboost engine. I need that information in order to give you a best guess. Are the trips you make almost daily long or short? The 3G section on this board is in the main menu. If you have either of the ecoboost engines, chances are your issue is already addressed by multiple posts and answers.
@ralph7up the title says 2020 Ford Escape Hybrid Titanium.
Doesn’t mean anything. Some members post in threads with engines that don’t match the thread title. That’s why confirmation is sometimes needed.
So you’re telling me the OP didn’t write the title....
Thanks. Missed that. Too used to seeing in text or signature line. Poster then has the 2.5 Atkinson engine with battery as for engine starting and no S/S per se. it is the hybrid. Likely that owner got a bad 12 volt battery.
Oops, my bad. I didn’t know he was the op of the thread.
Look for the build date on the sticker on the driver's side door jamb. Your 12v battery could have gone bad if it sat on the dealer's lot for months before you bought it, then if you drive it infrequently, It may not be able to accept an adequate charge. I would have the battery load tested (surprised the dealer didn't do that).
"Decided to quit screwing around with the Ford tiny battery and took your advice. I bought a H6 (group 48) AGM battery. You are right it exactly fits the space in the trunk where the original battery was mounted. Once I was in there I set up a parasitic test to see if there were any large current draws. My amp meter could only go down to 100 mA where it would read 0.01, so I suspect the draw is lower. Anyway, I am hoping the larger battery takes care of the strange behaviors I have been seeing. I'll post how it goes over time."
This maybe obvious but I’ll ask anyway. I tried to pull the red rubber boot backward but it wouldn’t move. Jiggles around a bit but firmly in place. Is there a trick to doing this?
I should have said: Instead of a red rubber boot I have a red hard plastic cover over the positive post.
Your dealer is correct in saying the stop/start feature will not work unless the battery is at it's optimum charge. If you do not drive the vehicle much or only take short trips you are probably wise to put the battery on a trickle charger as advised unless you take it for a regular 30 mile or more trip.
