The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides diagnosis and procedure information to be applied when diagnosing potential fluid leaks on front and rear brake calipers. This information has been developed to reduce unnecessary brake caliper replacement.
full bulletin at NHTSA ↗This Service Information bulletin announces instruction for application of additional lubrication between the brake caliper support and pad clips. This will prevent the pad from dragging due to corrosion buildup which may result in uneven or premature wear of the replacement brake pads. This additional instruction applies to all models with brake pads using the upper and lower pad clips and has been added to the brake pad installation procedures found in the related Service Manuals.
