Chrysler Group LLC has issued a recall for its 2008 Jeep Liberty vehicles, citing an issue with the vehicles’ windshield wiper motors. The recall could potentially affect 16,229 vehicles.

According to information from the National Highway Traffic and Safety Administration (NHTSA), the vehicles are equipped with windshield wiper motors “that contain excess adhesive that may allow for water intrusion, which could result in intermittent and eventually inoperative windshield wiper operation.”
Chrysler estimates that approximately 30 percent of the vehicle population will be affected, according to its November 3 letter to NHTSA notifying the agency of the problem. The impacted vehicles were manufactured at its assembly plant in Toledo, Ohio, between May 19 and June 27, 2008.
The windshield wiper motors were manufactured by Trico Products Corp. in Brownsville, Texas. Chrysler discovered the problem during an analysis of its third-quarter 2010 field data, when it determined “that the rate of inoperative 2008 [model-year Jeep Liberty] wiper motors had increased.” The company analyzed that data further to indicate the May 19-June 27, 2008 timeframe in which the vehicles were made.
“Analysis of returned parts indicates that the motor failures during the suspect period are caused by both water ingestion and excessive adhesive on the motor magnets,” writes David Dillon of Chrysler in the notification letter. “The water ingestion is caused by the removal of a vent in the wiper motor. The vent allowed the motor to equalize pressure with the atmosphere during a water spray thermal shock and not draw water into the motor.”
On June 27 of that year, the Toledo plant began using wiper module assemblies with an enhanced motor magnet adhesive application process, according to the letter. Company officials say they are not aware of any accidents or injuries related to the issue.
The company reported the recall to NHTSA on November 3, and has said its dealers will replace the windshield wiper motor free of charge.
