My 09 reg C-Max has just suffered a second Power Steering failure in the last 5 weeks.
Both repaired under warranty, both reportedly due to water ingress down the electrical cable loom.
Both failures occurred on starting the engine so at least I was not travelling.
Is this a common fault?
In both cases, immediately following the failure (for around 10-20 minutes), I was unable to steer the car. This later eased to very heavy steering, to enable me to drive home/drive to the dealer. both journeys around 2-3 miles. The heavy steering seemed to include pushing against the hydraulic fluid.
I am concerned that there may be a failure mode scenario where the pump fails whilst driving andthe steering fails due the hydraulic pressure.
The possible consequences are horrifying.
Am I worrying over a scenario that could not happen? or is my concern real?
