Summary: Certain sport utility vehicles have a rear side closure latch that may not latch or unlatch due to corrosion caused by road splash, such as water and road salt. These vehicles were originally sold in or currently registered in the following states: connecticut, delaware, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin, and the district of columbia.
Consequence: If the door is not latched properly and it goes unnoticed, it may open while the vehicle is in motion. If an unbelted occupant fell out of the vehicle, personal injuries could occur.
Remedy: Dealers will install a seal along the lower part of the rocker panel to prevent intrusion of corrosive material, and inspect the rear side closure latches. Functional latches will be cleaned and lubricated. Non-functioning latches will be replaced. The recall began on February 24, 2006. Owners may contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or Isuzu at 1-800-255-6727.

Has your Chevrolet been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Chevrolet dealer can also check your VIN. Recall repairs are free.
