Electrical system
4 reports
“The check engine light appeared on my 2018 Volvo s60. After taking the car to 2 Independent mechanics and the dealer, it was diagnosed as an Engine Control Module (ECM) failure. My 2018 Volvo s60 has ONLY 44,200 miles. The dealer stated that they "haven't seen this failure in cars with such low mileage. Usually, cars have 125,000+ miles if/when the ECM fails". The dealer and an Independent mechanic both stated that the brakes, steering, starter, thermostat, etc., could fail at any time. This could put my family, and other families on the road, at risk. Volvo refused to pay for the repairs.”
