Customer Notification
Beginning on September 3, 1996 affected customers will be notified of this campaign on their vehicles by letter from Cadillac Motor Car Division. A copy of the customer letter is included with this bulletin.
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure to do so could legally be determined to be lack of proper maintenance, and that the vehicle may fail a state or local emission inspection test if the recall work is not completed. Additionally, if the dealer finds that the emission system has be intentionally disabled, the letter explains that the cost of system restoration, so that it will function as designed, is the responsibility of the customer.
Regardless of whether the owner decides to have an intentionally disabled emission system repaired, the dealer should perform the campaign correction unless it is determined that performing the remedy without repairing the intentionally disabled emission system might create a risk of accident or injury.
