Should I buy a 2011 Mercury Mariner with documented electrical problems?

Depends on the price and the specific vehicle. Documented electrical issues should be priced into the purchase — if the seller is asking full retail, negotiate down by the expected repair cost. A pre-purchase inspection from an independent shop tells you whether THIS specific vehicle has already shown the symptoms or not.
