A news report today is claiming older Nissan Altima cars are having a rust problem with their floor pans
At first i was thinking it was caused by rock salt and sodium chloride used by northern states to melt snow and ice in the winter. But it turns out the Altima is rusting from it’s inside out. Hard to point the finger at rock salt and sodium chloride in that case.
The problem has not been diagnosed yet, but is suspected to be caused by poor drainage causing the floor pans to rust from the inside out.
From NBC News: Hundreds of motorists have complained to the feds that the bottoms of their older-model Nissan Altimas are rusting through, potentially putting their feet awfully close to the road.
The National Highway Traffic Safety Administration (NHTSA) has received more than 400 complaints of rusted-out Altimas rolled out between 2002 and 2006.
Some came from states that have heavy snow, where road salt can eat away at metal – but not all of them. And Nissan Maximas from the same period had far fewer complaints.
Nissan said it has no plans to order a recall and notes that corrosion in older cars is not unusual.
“This issue is not considered a safety defect by Nissan or the government agency that administers safety recalls,” the automaker said in a statement.
