What the defect is
Equipment description: air bypass valves part nos. 20-401, 20-402, and 20-403, sold between august 1, 2000, and january 31, 2001, for installation on passenger vehicles to prevent ingestion of water into the engine. The valves are constructed of two plastic pieces sonically welded with a silicon diaphragm and foam spring. The weld seam can crack under high stress loads and the valve's internal diaphragm and spring may be ingested into the throttle body, which in turn, may cause the throttle to stick open.
What could happen
If the throttle is unable to return to the closed position, the driver may lose control of the vehicle possibly resulting in a vehicle crash.
What gets fixed
AEM WILL NOTIFY AND PROVIDE TO ITS CUSTOMERS A FREE RETAINING CLIP TO PREVENT INGESTION OF THE DIAPHRAGM/FOAM PIECES INTO THE THROTTLE BODY SHOULD THE VALVE SEPARATE. OWNER NOTIFICATION BEGAN APRIL 26, 2001. OWNERS WHO DO NOT RECEIVE THE FREE CLIP WITHIN A REASONABLE TIME SHOULD CONTACT AEM AT 310-484-2322X500.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 25 April 2001.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
Also contact the national highway traffic safety administration's auto safety hotline at 1-888-DASH-2-DOT (1-888-327-4236).
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
