Volvo recalls some hybrid model lines due to a possible software problem. The combustion engine may not be able to start.
The problem is that the estimated cooling current in the electric drive (ED) cooling circuit is incorrectly set to zero when maximum cooling is requested. When the estimated cooling current is set to zero, the inverter-generator module sets the available torque to zero, and the combustion engine does not start; a Volvo spokesperson describes the error pattern to asp-Online. This can lead to battery drain and loss of drive while driving, increasing the risk of an accident.
In Germany, 8,054 vehicles of the following model series for the 2022 and 2023 model years are affected:
| Make, Model (years) | Problem |
|---|---|
| Volvo S60 (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
| Volvo V60 (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
| Volvo S90 / S90L (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
| Volvo V90 (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
| Volvo XC60 (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
| Volvo XC90 (2021 – 2022) | The combustion engine may not start, leaving only the high-voltage battery to drive on. |
In the UK, that’s an additional 4,755 cars built between 26 April 2021 and 29 September 2022.
A rough half-hour ECM software update at an authorized service centre should fix the error. The internal action code is “R10198”, and the start date was 24. 10. 2022.
Where now?
