Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; VISIBILITY; VISIBILITY:WINDSHIELD WIPER/WASHER
Information Only â Windshield washer pumps have a high No Trouble Found rate. Washer pumps may fail to spray due to a clogged filter.
EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT:APPLIANCE:AIR CONDITIONER
This SKU is a Climate Control Module. The customer communication requested return of unsold inventory to inspect alignment pins and knobs. The alignment pins may be weak which cause them to break and knob material may be weak which could cause them to break. Breaking of the alignment pins or knob could prevent adjustment of the climate control system.
ELECTRICAL SYSTEM
Information Only: This bulletin provides dealers with a battery warranty quick reference guide to ensure the appropriate tests for battery warranty are performed in order to prevent battery warranty claims filed with incorrect or incomplete information.
EQUIPMENT
Information Only: Proper jump-starting voltage will eliminate high voltage related issues and equipment damage.
ELECTRICAL SYSTEM; VEHICLE SPEED CONTROL
Information Only â Vehicles may have the connector seals on the wheel speed sensor incorrectly installed, which may lead to water intrusion and corrosion in some vehicles.
