TrailBlazer 4WD L6-4.2L VIN S (2002)
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired
within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence
of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an
identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having
to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as
soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall
is not completed within a reasonable time.
