At highway speed of 70 mph and in a rainstorm, Nissan Frontier 2005 seemed to slip out of gear and never re engage. Was left on the roadside unable to shift into any gear. Motor would start and when shifted into any gear, would rev with no transmission engagement. Vehicle towed to a transmission shop who pulled the pan and found radiator fluid in the transmission. Told me that this was a common problem with Frontiers, pathfinders, and xterras, but Nissan was not taking responsibility for the design flaw. I am now left with a $6000. 00 dollar repair on a truck the is only worth about $6000. 00.
While driving at a speed of 60-65 on the highway my 2005 Nissan Frontier feels like the transmission slips out of gear and starts to grind. This occurs only under acceleration and I do not mean hard acceleration. I am simply at a cruising speed on the highway and trying to simply maintain a speed and the noise occurs daily. I am not positive that the noise is coming from the transmission because I am no mechanic, but the sound is a grinding sound which means it is a gear grinding somewhere. I took the vehicle to a Nissan dealer three times and all I was told is that the transmission is okay. I do not have a service engine light on so maybe that is the reason, but I was able to show the dealer the noise and still no help. All I wanted when I bought this truck is a reliable car and I do not have one. Nissan should be held responsible for putting out a subpar product. I know based on the online forums that I am not alone in these issues with the truck.
