Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

MALFUNCTION OF THE AIR BRAKE SYSTEM COULD RESULT IN A VEHICLE CRASH.

MERITOR WABCO IS RECALLING 4,520 QUICK RELEASE VALVES (QRV) MANUFACTURED BY HALDEX BRAKE PRODUCTS FROM MAY 27 TO OCTOBER 15, 2008, AND BEAR CORRESPONDING PRODUCTION DATE CODES OF 148 THROUGH 289.

THE AFFECTED VALVES WERE LABELED WITH THE FOLLOWING MERITOR WABCO P/NOS. 9738990110, 9738990030, 9340990100, AND 9340990200 AND DISTRIBUTED TO CERTAIN VEHICLE MANUFACTURERS.

THE RUBBER DIAPHRAGM INSIDE THE QRV MAY EXPERIENCE DELAMINATION RESULTING IN SIGNIFICANT LEVELS OF AIR PRESSURE LEAKAGE PAST AND/OR THROUGH THE DIAPHRAGM, OR THE DEVELOPMENT OF A BUBBLE IN THE DIAPHRAGM WHICH MAY TRAP AIR PRESSURE IN THE VALVE AND NOT ALLOW THE SERVICE OR PARKING BRAKES TO RELEASE.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
  • How many have been returned or fixed isn’t in the notice.
