Has the Volvo XC90 T8 PHEV a rear-axle issue?
Hi,
I'm looking at Volvo XC90s. In the 2019/2020 T8 hybrid, should the known ERAD problem be a concern? Is there anything to mitigate the risk? Does Volvo cover replacement if the vehicle has a full Volvo service history? Or is it safer to stick with the D5/B5 variant?
Thanks

Hi Donal,
For the benefit of our other readers, ERAD stands for Electric Rear Axle Drive, which is effectively the electric motor used on the rear axle of the plug-in-hybrid XC90 T8 (and other Volvo PHEVs) to give it all-wheel drive and fully electric operation. And yes, they are a known weak point of the car.
There is some evidence that Volvo will help with repair or replacement for cars with a full service history, but it seems to be dealt with on a case-by-case basis as there has been no official recall or statement on it from Volvo. Do not rely on this.
We'd strongly recommend you avoid early cars unless the ERAD unit has been replaced relatively recently, but Volvo did make improvements as early as 2018, and the facelifted cars from 2020 on (badged “Recharge”) are a relatively safe bet.
Look not only for a regular service history, but also for maintenance details relating specifically to the rear axle.
The D5/B5 cars are certainly a better bet in terms of dependability, but obviously come with higher running costs and motor tax.
