Re: MPG drop after recall?

I had the S27 recall done recently and have noticed a decrease in my mileage. My usual use has been 9.1 L/100km before and after the recall I seem to be getting more like 10.1 L/100km. A 1500km prior to the recall netted an average of 8.1 L/100km - no long trips planned in the near future, so be a bit before I can compare that.

But that was only on 1 tank so far, will see what it is like after a couple more.

One other thing I personally noticed after the recall is that unlocking/locking the doors from the door handle seems to be hit and miss. Sometimes it will unlock right away, and other times you have to try it a couple times (once it would not unlock). Pushing the button to lock seems to be hit and miss now as well.

(yes I tried a new battery in the fob, but the wife's also does the same thing)

Maybe that was just a coincidence with the handle having an issue?

On the plus side, for 2014 owners the S27 recall implicitly fixes the issue where the cargo hatch periodically wouldn't open unless the remote button is pressed 4x instead of 2x. I've been waiting for that fix.

Oh, and the white "stuck pixel" above the odometer on EVIC is fixed too. Never expected a fix for that bug, given how much of a pain it is to flash the EVIC panel.

Except that it seems to have traded it for a similar, but even more annoying (to me) problem. It seems now I can't do the remote start if the jeep has been sitting for "too long" (I think it's roughly 12 hours but haven't really done enough tests to figure out the actual time). It had me baffled at first. I'd do the double press of remote start but when I got to my jeep it wasn't on. First couple times I figured I must just have been out of range or something. But then I tried it standing right next to it and no matter how many times I hit the remote start it wouldn't start. I was also looking at the EVIC to see if it was complaining about something (low fuel, etc).

Then to see if the problem was with my FOB I tried the unlock and that worked. Then I tried the remote start and it worked. I've repeated the experiment multiple times and it seems doing a lock or unlock then allows the remote start to work.

I haven't done any searches on the forum yet to see if others have experienced this issue.

Hm, I haven't heard of any problems with remote start... especially ones that have the same basic etiology as the cargo hatch problem that was fixed in last year's BCM release (i.e. the software implicitly included in the S27 recall). Does your cargo hatch work reliably with two presses instead of four now? If not, something else may be awry with your BCM.

My issue with remote start is that it only works from about 30 meters away. I rarely use it because it would only "warm up" for about a minute before I reached the vehicle by foot anyway.

I've had much success with the UConnect iphone app. Not sure if that's an option for you, but thought I'd mention it. I've not had the issues with the rmote start though...so far mine works great and I use it all the time. I do however have the issue with locking the vehicle via the handle button occasionally.

I've wondered why the remote won't always open the rear door normally. I'll have to test it out to see if it's no longer an issue.

Re: MPG drop after recall?

I didn't immediately notice some of the other fixes discussed here, but I'll be glad to see if they are indeed fixed.

However, I did notice that my engine oil life monitor now is now showing more oil life usage than before. In the 100 miles since I got the recall done this weekend, I have lost 3% oil life. Previously it was 100 miles per 1% like clockwork. I almost thought the thing was just calculating it based on the mileage since last reset counter because it was so predictable, but with a 10,000mi per oil change diesel, the calculation made sense and I never paid much attention to it. Now however, it is ticking away much faster. Anyone else noticed this?

My understanding is that on the 2014's, the BCM went to sleep rather quickly after vehicle shutdown and therefore didn't register the first two clicks. If the BCM were still awake, or awakened by some other function such as the unlock button, then the hatch would work with two clicks. Otherwise it was 1 to 2 clicks to wake the BCM and then 2 to activate the hatch function.

This was fixed in a BCM update for the 2014's last year. That code was implicitly included in the S27 that flashed the BCM, et al.

The "stuck pixel" graphical artifact requires a flash of the instrument panel to fix. My understanding is that instrument panel part of the flash sequence is why the S27 recall takes four hours instead of "minutes". The PCM, TCM, and BCM are all relatively quick to flash.

Re: MPG drop after recall?

Had the shifter recall last week. Immediately noticed a change in shift patterns, particularly hard shifts into 2nd and 3rd gear.

Mileage seems to be off too, but am not through a full tank yet.

Anyone else experience a change in the shift patterns?

Re: MPG drop after recall?

I'm going to jump back to this. Had the recall done about a month ago and have seen a 2-3 mpg drop since the recall. Anyone figure out anything? Always got 24-26mpg mixed and now only get 21-23. Jeep has 51k on it and was always consistent mpg up until the recall.

Same here. Don't like the shifting now and not sure on the mileage. Only been a few weeks and I've been driving very aggressive to make it shift without laboring the engine. That's when mine hard shifts. After s27 that is.
