Some vehicles were assembled with contaminated brake fluid and may experience a degradation of the sealing components within the brakes system, leading to potential loss of braking, Chrysler stated in its defect information report Nov. 10 to the National Highway Traffic Safety Administration.

Chrysler started an investigation Oct. 26 in response to contaminated brake fluid being dispensed into vehicles at its assembly plant in Toluca, Mexico, and placed the assembly yard on hold. It was determined that one drum was filled with a red-colored fluid that was suspected to be power steering fluid, Chrysler said.

Workers completely disassembled the brake evac and fill machines, replacing all nylon and rubber components as well as replacing internal tanks. All other components were washed in soap and water then dried thoroughly. The assembly line was restarted on Oct. 26 at about 9:30 p.m.

The company will conduct a voluntary safety recall on all affected vehicles to replace all brake components that come in contact with hydraulic brake fluid. Chrysler planned to begin notifying dealers in November and owners in December 2011.
