NHTSA Complaint #11496839 — 2013 NISSAN PATHFINDER

Three times our battery has ruptured. Two separate batteries, the second and third being a Nissan dealership battery because I thought maybe the aftermarket battery was the cause. I have purchased four batteries over the two years I have owned the pathfinder. The first battery that came with the car I did not see the battery condition as the car was towed in after it lost power while driving up hill. They assumed alternator however concluded it was the battery. When looking at the new battery the dealership installed I noticed corrosion from the splash of battery acid all over the engine bay. It wasn’t until I was in the car when the new battery once again ruptured, separating the whole top and bottom casing. That left acid dripping in my engine bay. So battery number three I made sure was an OEM Nissan battery that could handle the Platnium OEM options. Just months replacement the battery ruptured again. This time the dealer covered replacement. Well I brought my pathfinder in for its 60k mile service and sure enough the battery acid has caused the area around terminals to separate and have huge amounts of corrosion. The advisor even mentioned how the battery looks brand new and shiny except for all the corrosion. They got the battery holding a charge but can’t pinpoint the issue. I can not find a lot of info on batteries rupturing like this without being attached to an external power source - Like it someone is over applying voltage to the battery. That was not the case I have been actively driving when it pressurized the battery causing the rupture and spewing battery acid throughout the engine bay.
