Not Using Electric Mode

[dafish]

SOme

Mine was fine again this morning - did a ~30 mile drive, about 8 of those in electric mode which is typical.

Yesterday was the only day I noticed it staying in gas mode - I plan to just keep an eye on it and see if it happens repeatedly.

Wait! What? You typically get 8 miles out of 30 in electric mode? Huh? How?

From a stop a bicycle, heck maybe a wheel chair, out accelerates anything I can do on-bat, and I'm pretty sure 40-42mph is top speed on electric mode for me. With a tailwind. I can't imagine any scenario where I could be over 25% of my miles on electric.

So please, tell me more? What kind of drives are these, etc..

Thanks!

My drives are mostly 45-55 MPH rural roads. Not much stop and go. It switches over to electric whenever I am going a constant speed on flat surfaces for a while. It also switches most of the time I am going down hill.

I am consistently 25-30% electric miles.

There are so many parameters in play for the Hybrid side of the Powerboost. And considering the number of PCM/ABS updates since the release of the job1 2021, the code has been and is continuously being massaged.
I drive a 24 year very repetitive route to/from the office. About 46 miles round trip. I have meticulously monitored the truck for nearly 3 years. And while I too average about 20-25% electric miles, you would think that I would get near identical EV behavior day to day in the same places. But on some occasions it's not nearly as predictable as that. Especially with ambient temperatures varying.

In my opinion, on those occasions the truck will appear to be locked out of the normal electric mode. It's like some unknown (unidentified) parameter has the algorithm nixed?

A key cycle is a sure fire way of rebooting the trucks Hybrid strategy. I have also been able to trigger an end to an EV drought by switching to Tow/Haul on the fly, watch the SOC peg at 63% or more, switch back to Normal, and EV kicks in.

It doesn't happen often enough for me to learn anything definitive. But I'm pretty certain that the shear number of lines of code running on this truck leaves plenty of room for "random" bugs. I just marvel that it works so well most of the time.

You are indeed the PowerBoost Whisperer
I will certainly try tow/haul when it gets stuck in a loop next time

In the winter, my daily commute averages ~20-25% full electric, and it's 30-35% in the summer. About half my drive is 40-45 mph with several areas with minimal incline and a few spots either way with a place I can get ~½-1 mi of full electric at one shot. I've also driven it enough to know when/where I can push extra electric milage and where it's not worth trying.

You guys are doing awesome if you are getting 25% electric mode. Even in eco mode driving very mildly, mine is only about 17-18% and I'm only about 20-21 mpg. I'm going to have them take a look when I take it in for the no start issue.

I posted on here Jan 27th which was the first time I noticed my truck not switching to EV mode. Yesterday evening it did the same and I too got that exact error message this time.

Trying to get it into the dealer next week!

I have had my truck diagnosed by the dealer, they said the 'alternative Starter control module' was randomly failing, causing the truck to not go into electric mode (in my case, when idle and usually in Generator mode). This could cause a no-start scenario, or many other problems if it is defective and spewing out garbage onto the network.

however this recent code, shows a fuel error. And this looks like it is the PCM, not the module mentioned above.

Q. is the PCM simply the reporting module detecting the problem, or is it the problem itself.
Q. Could the reference to 'error' be false due to the bad module above?

The truck drives fine although the trans hard shifting may also be related to this problem, dealer had the trans approved for an overhaul, and it was found to be fine, so suspicion is back to this module above.

I don't know what that fuel message in the freezeframe data means, but I wouldn't read too far into it - you'll drive yourself nuts trying to make sense of the little errors and codes these trucks throw since they're usually harmless.

In researching this, I've never seen anything to make me think the cause of this issue is anything other than the BISG (starer/generator). The BISG can't report anything - the PCM is what will throw a code on its behalf. I think your dealer is correct.

I have not had this happen a second time on my truck, so I'm just calling it a fluke for now.

I'm curious if anyone else has noticed behavior like this.

Typically, I see 25-30% electric miles with my truck. Today driving home from work (25 miles) I noticed it wasn't going into electric mode, even at stops. Whenever checking in situations where I'd expect it to turn off the gas engine, it would say "Engine On Due To Normal Operation"

I got home, checked codes with ForScan and there are just two unrelated and seemingly harmless codes that it's been throwing for a long time (on the TRM and GWM). I checked the hybrid battery state of charge out of curiosity, and assuming I picked the right data field, it was at 62%.

I started researching and some say this happens after a PCM update, but as far as I can tell the truck hasn't gotten any updates - last one was PowerUp 6.1.0. I then went for another short drive and it used the electric motor regularly, just like it normally does - actually did around half of those miles on electric.

Anyone have anything like this happen?

I just posted on this after an update occurred. It went back to normal the next day.

 

[Snakebitten]

There have been a few reports of trucks getting new BISG (belt integrated starter/generator) on Powerboost trucks.
Almost unheard of here, and then suddenly a few posts for a few fellas, and then it went quiet again.

Perhaps a small batch of faulty ones?
Regardless, the only real pain that I recall was the lengthy delay in acquiring the replacement. Which often is the case it seems.

 

[js312]

Mine did this again - no electric over two drive cycles, then it lit the CEL. On the next drive cycle, it used electric again and the CEL went out.

I'll probably call the dealer and see how they want to play it. Hopefully at least they can pull the code out of PTS to keep on record before it disappears.

Just chiming in that my 2021 has been doing the same thing. Noticed it the week of thanksgiving and it has been doing it on and off since then. Main symptom is just that the engine is on when it would normally be off. Seems to happen randomly about once a week.

No check engine light yet, but I occasionally get a wrench light. I've found I can force the wrench light to come on by keying off to shut the engine off (but don't completely shut down the vehicle), then keying back on.

PTS confirms the truck is reporting the P0A1E code (looks like two different codes, actually). My basic OBD code reader doesn't see anything. I don't think the delear will do anything without an active check engine light, so my plan is to just keep an eye on it (esp. if the fix is a new BISG, which are on back-order).

Truck runs great otherwise with just over 60,000miles on it.

Do you currently have PTS? If so, would you mind if I PM you my VIN to see what code(s) mine threw?

My truck is back at the dealer exactly one year later for this same issue. Dropped it off this morning. I’m very curious if they replace the BISG again…
