DIY Oil Changes Lead to Warranty Denial for Subaru Outback Owner

An Ontario driver who serviced her leased Subaru Outback herself for two years is facing a warranty denial after the engine developed serious problems. Shannon Desjardins told CTV News that her 2024 Outback showed a red oil warning light in January at around 44,000 miles (71,000 km).

The light went away the next day, then returned, prompting her to have the vehicle towed.

According to Desjardins, the dealer found sludge and other significant engine issues. When asked for service records, she explained she had performed the oil changes herself. She claims the dealership refused warranty coverage solely because of her DIY maintenance. "They're telling me the only reason they are denying it is because I did my own oil changes," she told CTV News.

Subaru Canada responded that owners may perform their own maintenance, but they must follow the manufacturer's schedule and keep documentation, including receipts for products used. The automaker says it is investigating Desjardins' case. It remains unclear whether she followed the required procedures exactly.

Meanwhile, Desjardins continues making lease and insurance payments on a car she cannot drive while awaiting a decision. If Subaru upholds the denial, she could face thousands in repair costs. The situation highlights the importance of keeping detailed records when performing your own car maintenance, especially on a leased vehicle.
