What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
In a hard-braking situation, brakes failed - no discernible deceleration at all, pushing harder than I've ever had to before. This made for rear-ending the guy ahead of me. Forensics investigator w/ mech found odb dtcs showed only p0a8d and b1318 - one of which shows a low voltage to ABS system. Multiple reports of this with escape hybrid owners. I wonder if it is related to the ford fusion hybrid failures? This occurred at 10-15 MPH. What happens at 60?
Tl* the contact owns a 2008 mercury mariner hybrid. The contact stated that while pulling into a parking lot at 3 MPH, she attempted to engage the brakes but they failed to stop the vehicle. The contact mentioned that the ABS and the check brake warning lamp illuminated. Also, the contact stated that she had to crash into a tree in order to stop the vehicle. No injuries were reported. The vehicle was towed to the dealer. The manufacturer was not made aware of the failure. The vehicle was not repaired.
I have a 2008 mercury mariner hybrid 4 wheel drive. On occasion the steering will loose power assist while turning. The loss of power lasts for a few seconds before the power assist returns. This problem is dangerous as I have to compensate for the loss of steering assist by turning the steering wheel harder, then when the power assist returns the vehicle turns more than I want because the wheel is easy to turn as I am applying a lot of pressure to the steering wheel.
Regenerative braking system light appeared on dash, 2013. Took vehicle in to get checked. Was told that it was the master cylinder. Cost approx 1500.00. Went on line and found that other people had same experience and after paying for the replacement of the master cylinder they then had to replace the an ABS module to the tune of 4500.00. Took my vehicle to another dealership feb of 2014 and was told the ABS module needed replaced for 4,724.00 and then the master cylinder for 1360.00.
ABS brake light came on, with regen brake disengaged notice appearing, hcu unit failed, seems to be a frequent problem with hybrid
