The National Highway Traffic Safety Administration has closed a preliminary investigation into over a million Toyota SUVs without taking any further action, Reuters reports.
An investigation of around 1.8 million Toyota RAV4 vehicles from model years 2013-2018 was first initiated in 2021, following reports of fires igniting in the engine compartment.
In the course of its investigation, NHTSA analyzed potential causes of the fires, and the frequency at which they occurred.
The agency discovered parts within the engine bay that were creating friction between the battery hold down bracket and the positive terminal of the 12V battery, but said that reported incidents occurred with either aftermarket batteries, or the vehicle’s original battery that had aged out of use.
As a result, the problems have not been attributed to any manufacturing error, and NHTSA will not be pursuing any further action.
