Yep, this is what I've seen on the ones I've done.I have a 2015 V60 & '16 S60. BOTH had loose starter to solenoid lug fasteners. Loose lug can temp weld itself and not pass amps. Then resume later. Both cars have done the NO restart trick.
Volvo needs to look into. The starter is real robust and the brushes were 80 and 95% good on them. Cars had also had new main batteries before 25k, the '16 had gotten 2. Huge waste of moola.
