Nissan has been able to largely avoid mention on this blog because they have not had a lot of prolific recalls. That may change. The National Highway Traffic Safety Administration is apparently received numerous complaints from drivers of Nissan Frontiers, Pathfinders and Xterras who are complaining about transmission failures because of a leaking radiator coolant.
Nissan, to their credit, has extended the warranties to cover radiators. But Nissan did not apply the warranty to vehicles with over 80,000 miles. Drivers report that the transmission failures are causing safety issues, like rapid slowing or the inability to safely cross an intersection. It is hard not to imagine car accidents flowing from this defect.
