2021 VOLVO XC90 Power Train Problems

Vehicle steer violently on pilot assist and powertrain disabled, not allowing us to steer the wheel on a highway. (Last year) We were lucky no other cars were nearby, needed a reboot for the wheels to work again. Dealership isn’t sure what happened. Now we have a hybrid system failure which a lot of cars with the same model Xc90 T8 is having with the hybrid system. Please investigate into this

Check engine light illuminated at 11,000 miles. Diagnostics showed a software update was needed but the software update did not fix the problem. Volvo corporate said the IEM module needed to be replaced. The IEM module controls the rear axle / propulsion and this is a serious safety issue because sudden loss of propulsion while driving at high speeds increases risk of having an accident. After replacing the IEM module, the mechanic cleared the DTC codes, test drove the car, and re-ran the DTC - and the code indicating a software update was still needed was present. Also the hybrid battery doesn’t keep its charge and depletes at an extremely fast rate.
