Hello everyone, I picked up my 2023 XC60 recharge in Feb this year and on 3/22, when I turned on the car, the turtle light and engine light was on and there were only 3-4 mph power for me to drive it back to garage. The car was towed in and 2 days after, they told me the fault codes retrieved weren't something they've seen before and Volvo tech support responded with a long list for them to check a day after. Today I'm told they found the problem which the Hybrid Starter Generator Control Module is faulty.

I'm wondering if anyone with XC60 recharge encountered the same problems before and whether this malfunction will impact the life of the battery or any parts of the vehicle? Thank you!

 

Sorry to hear about this. I'm not an expert, but I wouldn't expect this failure to impact the life and health of the primary battery. The good news is that they found the origin of the issue and can fix it. Often I read about people with intermittent check engine lights hearing "it's just a software issue" or "it's working fine now" with no real resolution.

 

I had an identical failure and started another thread before I saw your message here. Rather than write it all out again, I’ll cut and paste from the thread I started.

My 2023 XC60 Recharge with 20,000km on the clock left us stranded after going into reduced performance mode with the turtle symbol while driving in rural NSW a few weeks ago. After pulling over and switching off we were unable to switch back on with no electricals functional, unable to close windows, unable to activate centre screen etc. The car had been in Hybrid driving mode but was driving on the internal combustion engine at the time having transitioned normally from the driving battery some 30-40km previously.

Roadside assistance said the 12V battery was flat and connected a charged battery pack. He was unable to get the car started but some of the electricals worked but only erratically. He said his battery pack was being drained very quickly implying a short circuit of some sort. Managed (with difficulty) to release handbrake to load the car onto a truck and got trucked to nearest dealer approx 120km. 27 hours later we got home from the time of breakdown.

2 weeks later we have the car back after the IGM part number 36003582 ($3000+!!) was replaced under warranty. A quick google search shows this to be a “Hybrid Starter Generator Control Module A module which controls starter and generator function of the hybrid electric motor“. The Volvo service technician indicated that there had been an internal short circuit of this particular module so the module was replaced and the relevant software reloaded.

So my 18 month old car has left us stranded on the side of the road a long way from anywhere. Thank you to Volvo roadside assistance for getting us out of trouble but unfortunately the experience has left me a little wary of any future road trips particularly one that may involve travelling outside phone coverage. I could add here too that we have just come from a 2002 Honda MDX which we bought new, drove for 20 years covering 300,000km and it never once left us on the side of the road or had any failure of any sort.

My question is this…has anyone else had this particular module fail? Is this a known problem with this vehicle? Will replacing the faulty module with an identical module leave us prone to the same breakdown potential? Has anyone got any advice on this issue?
