00009 -- Engine Cradle Corrosion
1990-93 W Model Vehicles
Located in the High Corrosion Provinces of Newfoundland, Nova Scotia, Prince Edward Island and New Brunswick
Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1990-93 W model vehicles located in Newfoundland, New Brunswick, Nova Scotia and Prince Edward Island where exposure to moisture and salt can cause extreme levels of corrosion. Some of these vehicles exhibit a condition in which corrosion has caused loss of metal thickness at or near the engine cradle mounts. If sufficient metal thickness is lost, one or both of the front retainer and/or mounts may pull through, or the cradle may fracture forward of the rear mounts. If failures occur at both front or both rear locations, movement of the cradle can cause separation of the steering intermediate shaft. If this happens while the vehicle is moving, a crash could result without prior warning.
Correction
Dealers are to inspect the cradle assembly and install reinforcement plates. In vehicles where there is sufficient remaining metal thickness at the cradle mounting locations, a new cradle assembly will be installed.
Important
Cradle replacement will require DSM approval before repairs.
Where the engine cradle replacement repair costs may exceed the current fair market value of the vehicle, consult with your District Service Manager before proceeding.
It may be appropriate to assist the customer in purchasing or leasing a new or used General Motors vehicle. The offer of assistance must not exceed the fair market value of an identical model vehicle in similar condition but not requiring the engine cradle repair or the value of the repair, whichever is less. Licensing, sales tax, etc., would be customer responsibility.
Due to the age of the vehicles involved, published used vehicle value guides may not provide fair market values. It may be necessary to contact wholesalers or survey prices in your local market.
In very unusual circumstances, where the customer insists they are unable to afford any of the alternatives offered, a cash payment for their vehicle may be appropriate. Note: The customer is to sign a release.
Any vehicle purchased from the customers through the assistance outlined above must be scrapped in accordance with local practice so that it cannot be put back in service.
If the customer chooses to decline the fair market value offer, they should be advised that their vehicle is unfit for service and the Motor Vehicle Registrar will be notified by the Dealership.

Dear General Motors Customer:
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1990-93 W vehicles. Some of these vehicles operating in high corrosion provinces of Newfoundland, Nova Scotia, Prince Edward Island and New Brunswick, exhibit a condition in which corrosion has caused loss of metal thickness at or near the engine cradle mounts. If sufficient metal thickness is lost, one or both of the front retainer and/or mounts may pull through, or the cradle may fracture forward of the rear mounts. If failures occur at both front or both rear locations, movement of the cradle can cause separation of the steering intermediate shaft. If this happens while the vehicle is moving, a crash could result without prior warning.
Your GM dealer will inspect the cradle assembly and install reinforcement plates. In vehicles where there is sufficient remaining metal thickness at the cradle mounting locations, a new cradle assembly will be installed. This service will be performed for you at no charge .
You may be contacted by a dealer other than the dealer who sold or is currently servicing your vehicle. Please be advised that you may take your vehicle to the General Motors dealership of your choice to have the recall service work completed. Please contact your dealer as soon as possible to arrange a service date.
If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.
This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
