20. 2005-2010 Nissan Pathfinder
The Nissan Pathfinder is one of Nissan’s first entries into the SUV market. It sold well and was relatively popular, but the 2005-2010 model year Pathfinders had a serious mechanical defect that makes it a terrible choice for a used car. There was a defect in the coolant system that caused a coolant leak, as if a leaking coolant line wasn’t bad enough, the system leaked into the transmission causing catastrophic transmission failure. The transmission requires replacement, which could end up costing upwards of $3,500.00 according to owner reports. Other issues reported with the Pathfinder include fuel system problems and body / paint problems. Much like the Honda Accords that suffered from transmission failures, if the owner can’t provide proof that the vehicle has had this defect corrected, avoid this car at all costs.
