Recalls: Jeep WK2 Grand Cherokee

2012-13 Jeep WK2 Grand Cherokee: increased brake pedal resistance

In March 2014, a recall was issued for WK2 Grand Cherokee vehicles that were manufactured in 2012 and 2013. In these vehicles, the Ready Alert Braking (RAB) System may result in the driver experiencing a hard brake pedal feel. Due to increased pedal resistance, the driver may not apply the brake pedal as intended, thereby lengthening the vehicle’s stopping distance (PRA 2014/14036).

2011-14 Jeep WK2 Grand Cherokee: reduced braking ability

In April 2014, a recall was issued for WK2 Grand Cherokee vehicles that were manufactured from 2011 to 2014. In these vehicles, the brake booster had a centre shell which could corrode over time and allow water to enter. If water entered the centre shell it could freeze, thereby reducing the vehicle’s braking ability and increasing the risk of a crash (PRA 2014/14060).

In November 2017, a recall was issued because the brake booster water shield that was to be fitted as part of PRA 2014/14060 may have been incorrectly installed. As a result, the brake booster water shield may not be effective in diverting water away from the brake booster assembly – this could cause corrosion and water intrusion of the brake booster. In cold climates, water in the brake booster could freeze and limit the braking ability of the vehicle – this posed a safety hazard to vehicle occupants and other road users. For the VINs of the recalled Jeep WK2 Grand Cherokee vehicles, please see PRA 2017/16427.

Jeep WK2 Grand Cherokee with Adaptive Cruise Control: untintended and continued acceleration

In June 2014, a recall was issued for WK2 Grand Cherokee vehicles that were fitted with Adaptive Cruise Control. In these vehicles, the vehicle may experience unintended and continued acceleration after the Adaptive Cruise Control had been overridden. If this occurred, the vehicle may accelerate to very high speeds and make it difficult to stop or slow the vehicle, posing an accident hazard to the driver and other road users (PRA 2014/14139).
