Campaign - Incorrect Transmission Mount Bolts
SERVICE UPDATEBulletin No.: 10361
Date: October 20, 2010
Subject: 10361 - Service Update for Inventory and Customer Vehicles - Incorrect Transmission Mount Bolts - Expires with Base Warranty
Models:
2011 Chevrolet HHR
This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.
Purpose
This bulletin provides a service procedure to install four new bolts in the transmission mount on certain 2011 model year Chevrolet HHR vehicles. Incorrect transmission mount bolts were installed on these vehicles that may result in loosening of the joint causing noise and vibration. If the noise and vibration is ignored, over time the bolts could break, resulting in more severe noise and vibration and component wear that could impact vehicle durability.
This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.
Vehicles Involved
A list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility.
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty system. Not all vehicles within the above breakpoints may be involved.
