According to the National Highway Transportation Safety Administration, the issue is specific to 2010 and 2011 model year diesel trucks. Models made between March 2009 and October 2010 may have been built with power steering reservoir caps with “excessive vent pressure levels.” Somehow, the faulty power steering cap causes the brake pedals to be slow to return.
We aren’t entirely clear on how the power steering cap impacts the braking system, but NHTSA says that the danger isn’t that drivers won’t be able to stop their trucks â€“ the brakes release when they should. Instead, the vehicle’s brake lights will stay illuminated for too long, increasing the likelihood of an accident.
Chrysler says it has received 175 reports of the issue, but it has received no reports of any accidents or injuries stemming from the defect. Chrysler will notify owners of affected trucks that it will inspect and replace the power steering reservoir cap for free as necessary.
