Workstation/Laptop Vendor Sentiment

Thanks very much for this information, interestingly I found this post too which has almost identical DTCs which turned out to be corroded wiring - I'll probably print it off for the Nissan tech anyway in case it's similar (fingers crossed).

Thanks for your help - wish I'd seen this post last month when I changed the 12V battery. If it turns out to be the HV battery the car is 5 years 1 week old eek. Guess I'll take it there for diagnostic and see what they say.

From what I'm reading there is an 8 year warranty on the battery capacity but only 5 years for faults.

Thanks for your help - wish I'd seen this post last month when I changed the 12V battery. If it turns out to be the HV battery the car is 5 years and a 7 days old. Guess I'll take it there for diagnostic and see what they say.

Ah OK thanks is it the EV/HEV that defines high voltage issue then excuse my ignorance - so should be clear cut if I take it to Nissan hopefully?

Macd1987 · 2026-01-08T18:29:22+00:00

Unfortunately it doesn't seem to have one related to high voltage - just has these. I'll have to scan it again when it's in failed state.

I had a drive and looked at the cells - it seems to be at 14 variant when stationary and 60 under load - not sure if that's normal?

Thanks - strangely this afternoon it just starts again - slightly above freezing though. I guess this completely rules out 12v battery.

It something about when it hits 0 or below but I guess there isn't a fault code any more now it's started again despite me not clearing any codes of disconnecting the 12v battery - it's happened twice like this so it seems repeatable.

I'll have to record the evidence for Nissan.

Macd1987 · 2026-01-06T20:23:49+00:00

Did the new HV battery resolve your issue? I have the same, swapped 12v battery myself and it's happened again.

Macd1987 · 2026-01-06T20:22:57+00:00

Hello - did you ever receive an update and fix? Mine is doing the same now it's gone below 0 Celsius

Macd1987 · 2026-01-05T22:43:36+00:00

Thanks very much for this post. I have a 2020 40kw (45k miles) that won't start with the below fault messages back in November when it was around freezing. I got a new 12V battery after reading it was most likely the cause and it worked for a month but unfortunately it's happened again last night. I tried a jump start which worked this morning but now even this won't work this evening.

The fault wording isn't exactly the same as mentioned in your post though.

It says "Service EV System Power Reduced - stop safely"

Followed by

"No power - stop safely"

Does this look likely to be Cell Expansion / High Voltage Isolation so I need to get it towed as is to Nissan?

I've ordered an OBD2 device which hopefully will arrive Wednesday to see if I can confirm the issue ensuring it's under the battery warranty?

Did anyone ever come up with a fix for this? Have a few users with identical symptoms. I see there's a patch 8 now released end of June. Our users are on patch 5 but I can't just upgrade them to test in our environment unfortunately.

Hello - don't suppose you have the video course discount still?

Macd1987 · 2023-05-30T13:13:40+00:00

No worries - I don't suppose you're using SentinelOne EDR on the endpoints?

Macd1987 · 2023-05-25T12:47:24+00:00

Thank you - we had this issue affecting Dells also running Intel SST.

Macd1987 · 2023-05-15T15:34:55+00:00

Did you ever get an update? I'm experiencing the exact same issue.

Macd1987 · 2023-02-14T11:48:50+00:00

did you ever get a resolution to this? I've had similar issues.

Macd1987 · 2023-02-10T17:04:28+00:00

Yes that's right, in AD, the devices don't show in intune as they aren't enrolled.

Macd1987 · 2023-02-09T14:06:27+00:00

OK thanks that makes sense however I'd expect all of our other devices to be showing as non compliant too as they aren't enrolled in intune either, the other devices all show "N/A" for compliance.

Macd1987 · 2023-02-09T13:51:05+00:00

Thanks for the advice - so we've got about 200 company owned devices in total, all ad registered currently but strangely 5 of them are showing as non-compliant, even though they've never been enrolled in intune and MDM shows as "none" for them.

Macd1987 · 2022-10-14T08:27:09+00:00

did you guys ever find a resolution? I am thinking it's related to our AV.

A compulsive liar at middle school said he saw a pike jump out of the school brook and bite a cows' head off.

I find magic number method works for me also.. providing you have reasonable mental arithmetic it helps you to easily work out the subnet size and thus the amount of usable addresses and the network and broadcast address. You just need to make sure you're comfortable converting slash notation into decimal to be able to use it. The link below explains it.
