| Description of the problem | When the brakes are applied moderately at around 40mph to slow down, and if a wheel go on top of some bumps or pot holes, car seems to loose braking power, brake padel drop about 1 inch, have to pedal hard to get the brakes back. At one time i saw a message on dashboard "not available" which i was not able to read and confirm, as this happened in a panic situation. This is occational but has happened to be 4 - 5 times now. My guess is car try to apply regenerative brakes first, if that cannot work due to excessive, bump / pot-hole on the road, it give up, and as a result, car loose braking power for 1-2 seconds. This 2 seconds can be life and death in an emergency braking situation. I took the car to dealer, and they said, no issues found. This problem is hard to reproduce, but can be reproduced. This happened in local roads with 45mph speed limit. One time when there was rough road due to construction. Another time when one tire was going on top of road dividers which are about 1 inch tall and 1 foot apart, it had many of these next to each other, when i was applying brake. |
