Bulletin Summary
During a recent investigation of reported battery fires in 2013-2018 RAV4 vehicles with gasoline engines (excluding hybrid models), Toyota discovered that many non-Toyota retailers and others who sell or install replacement batteries were recommending a small size battery for replacement. Toyota specifies a particular size replacement battery for the RAV4 that does not include this small size. The smaller battery may not fit securely with the RAV4’s battery mounting parts, and, in some cases, can move around when the vehicle is driven, causing a short circuit. Using the wrong size battery, or not installing a replacement battery properly, can cause damage to the battery and the vehicle, and it could cause a vehicle fire.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
