On my 2010 Forester I did have some work done on my rear hatch electric latch. Dealership fixed it by replacing latch button and addressing a short further up the line. This job was done about two months to three months ago and I didn't notice any problem until today. I was pulling into my garage and I noticed that when my rear wheels went over the bump by my garage entrance the daylight running lights blinked off and then came back on. It happened several times after that and then stopped once only to start again intermittently. What's up now. FYI Milage 94,000.
