  1. GM says it needs to bleed the brake systems of 230,000 previously recalled cars.

    Some of the recalled vehicles have rear brake caliper pistons that have hydrogen gas trapped inside that could be released into the brake systems. ZF, the manufacturer of the brake pistons, didn't properly temper and chrome-coat the pistons, causing hydrogen gas to remain trapped in the bodies of the pistons.

    Excess gas –– we’ve all had it, no-one likes it, and the same holds true for your braking system. This problem may cause your brake pedal to feel “spongy” but it’s unclear if it affects stopping distances.

  3. General Motors' Technical Service Bulletin (TSB 15285C)

    could be of great interest to 2011 Terrain owners who've been complaining about excessive oil consumption.

    _Chevy and GMC dealers were told in previous technical service bulletins to install updated engine control module calibration and perform an oil consumption test. This time dealers are told to diagnose the problem and replace the pistons ... General Motors says repairs will be made free of charge based on warranty coverage extended to 7.5 years or 120,000 miles, whichever comes first. The coverage begins from the date of sale of the SUV.

    This is great news for Terrain owners.
