Known issues on the 2014 Terrain. Two recalls are on the federal record. The headlight housings produce a reflection that lights areas outside the driver's own view brightly enough to glare other drivers, and the ball joints in the windshield wiper module can corrode until one or both wipers quit. Those two are consistent with the complaint record: of 301 filings with NHTSA, the engine draws the most, with visibility and wipers close behind and the power train third. Wiper linkage service, engine diagnostics and driveline procedures are all documented here.
