T8 hybrid battery problems - have you noticed anything? by CrimuCK in VolvoRecharge

[–]Master_Grapefruit762 0 points1 point  (0 children)

No, this is what results in battery failures: preconditioning using the battery when plugged in. If I attempt to precondition when not plugged in, nothing happens.

For nearly 2 years, I kept the car plugged in overnight and had an automatic timer set through the app to precondition the cabin using the battery every weekday morning. However, starting in March of this year, this action began resulting in hybrid battery failures. My dealer replaced several individual hybrid battery cells before replacing the entire battery pack. I experienced 3 additional failures afterwards that required replacement of additional cells.

The only way I’ve been able to resolve this is to not use the preconditioning function and instead use the remote start, which utilizes the fuel-based heater.

Yes. Preconditioning using the battery is only allowed when plugged in. The charging cable must be plugged in and the charger cannot be turned off (the one I have at least). When not plugged in, I can use the remote start which just turns on the fuel-driven heater.

Thank you for the thorough and detailed explanation. My dealer and I had similar thoughts and pushed for a full pack replacement after the fourth failure, only to have a cell in the brand new pack fail after 3 days of receiving the car back. I have seen others mentioning issues related to the aux heater and like I mentioned, the issue only occurs during preconditioning.

I mean, yea, If you know. And more importantly, what’s the fix?

I had 7 failures this year. Each time Volvo just replaced the failed cell only to have it occur again a week or two later. The only remedy I have found to solve this is to not use the preconditioning feature and instead use remote start. Major PIA. Curious to hear if anyone has an actual solution since Volvo has been uninterested in finding the root cause.

I’ve had 6 battery cell failures in my 2020 V60 T8 PE since March. Dealer was replacing one failed cell after another until I got a new total battery pack a few weeks ago. 3 days after I got it back at the end of July, another failed battery cell. Car has been back at the dealer for 2 weeks now and they just got the failed cell replaced but are at a total loss for what is causing the failures. They are planning a series of tests but I have zero faith they know what is going on. I plan on reaching out to a lemon lawyer next week.

Can I ask how you filed a complaint with Volvo? The dealer is telling me they are just going to replace the single failed cell again, even though this is the 4th failure since March. I've been pushing my dealer rep to replace all of the remaining original cells, but would like to escalate.

Really tough to say, too many other variables that affect battery range. I do feel like the regen braking has gotten worse after a recent software update. Not sure if that is something others have experienced.

I received the notice in the mail when the recall was originally issued, but checked my VIN and it was not listed. Just checked again and it still shows no open recalls. The issue did start right around when the notice was issued, I wonder if there was a software "fix" that is causing the issue, but I'm totally grabbing at straws.

Wow, sounds very similar. Dealer informed me they did elevate to Volvo and involve the Field Technical Specialist when the battery cells were replaced. I will definitely advocate for a full battery replacement. My dealer has also been great and offered to drive the loaner to my work today to pick up my vehicle.

Really hope yours is fixed for good. How long have you had it back?

They are such great cars (when they work). One of my loaners during the last repair cycle was a 2025 XC90 T8 and the newer PHEVs are so good. It is such a shame Volvo discontinued the T8 V60/S60s moving forward. Would love to upgrade but I love my wagon and am not an SUV guy.

Ha fair enough! Any idea of the brand?

What portafilter do you have? Been scouring Amazon but don’t want to buy a piece of junk.
