Park brake fail
My wife has a 2008 Pontiac Solstice with 22,000 miles. This summer I noticed that the emergency/parking brake did not hold the car, and searching here I found that's a common problem on these cars. It took 4 trips to the dealer under warranty before the brake would hold. However, I discovered this week that if the car is moving the brake does nothing. I can jerk it up as hard as I can and literally nothing happens. If the car is rolling less than 5mph you can discern a slight drag, but that's all. This also allowed my daughter, who just got her learner's permit, to drive off with the brake set and I didn't notice it until I smelled them. The dealer claims the brake was never intended to stop the car and that this is normal. He also claims all cars have always been this way, but I've never owned a car in my life that wouldn't lock the rear wheels with the e/park brake. (That's how I did all those cool bootleg turns back in high school!)
I can't believe that this is intentional. Without getting into the whole parking brake vs emergency brake controversy, it would be a liability for GM to have cars driving around with the brake set and causing brake fires and such.
My 2004 Jaguar XJR has an electric e-brake, and if you pull the switch when stopped it goes on instantly, but if you are moving it engages gradually, taking about 3 seconds to lock the wheels. This allows it to function as an emergency brake the way the owner's manual describes. I tried my sister-in-law's 2013 Lexus, and when I jerked the brake up the rear wheels locked. My friends 2011 Corvette will lock the wheels with the e-brake. Literally every car I've ever owned or ever driven does this, so I find it hard to believe that the Kappa is the ONLY car that is designed not to.
