NHTSA Complaint #11440067 — 2021 VOLVO XC90

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.
