What owners say
Consumer states that while traveling at highway speed the vehicles brake pedal went to the floor, consumer had to use emergency brake to stop. Took to dealer, dealer stated ABS pump failed and brake fluid leaked out, causing loss of pedal pressure. Please provide any further information. Mr
Wet braking problem--I have no brakes (delayed) for the first 2-4 seconds during, or after a rain.
When driving and upon depressing brake pedal when attempting to stop, experienced complete brake failure without prior warning which caused extended stopping distance. Also, directional signal and emergency lights malfunctioned.
In wet conditions, my brakes have delayed braking power. The wetter the conditions the more frequent and severe. After the delayed loss of braking power (approx. .5 to 1 second), the braking power appears to go back to normal. Similar to riding a bike with wet rims except that the car's braking power recovers faster. Very scary when you're cruising along on the highway in wet conditions with traffic and you come up on an unexpected bottleneck. I mentioned it to a dealer in santa clara, but he seemed clueless. He thought it was a function of the ABS, but I know what ABS feels like. I think it has to do with wet disc brakes.
Brakes failed completely at 15mph while approaching stop sign. Car continued right onto the highway. Abs did not kick in. It had rained that morning.
