Pearson is where I purchased my 14 Cx5.. All service done there.Went for oil change 8/25. Check thoroughly my vehicle. Noted battery corosion. They put in new one 14 months prior. 30 dollars to clean and I declined. Got home, inspection showed excessive positive post corosion. There was no grease applied!!? I completed and grease. Called and inquired; they don't do that anymore. VERY disappointed in customer service!!! Normally satisfied with their work. I should have had a talk with the boss.....
