2019 Volkswagen Golf Alltrack

I was making my final trip of my move from Minneapolis to the Denver area and was on [XXX] traveling West in the right lane. The truck ahead was moving from the right lane to the left to give room to a car stopped on the right shoulder. There was another car in the left lane so I couldn’t move to the left. The truck was soon blocking much of the left lane so the car in the left lane was slowing as I slowed. I then applied my brakes and the pedal went all the way to the floor without actuating the brakes! Fortunately, by then there was room between the truck and the car on the shoulder and I was able to miss both as I sailed by. Pumping the brake pedal restored the brake function. Thinking that I must be low on brake fluid, I pulled off the highway at the next large service station. The brake fluid reservoir was full. I continued to my new home and at my first opportunity I went to the nearest VW dealership and left it for several days to be checked. No error codes so they did nothing. VW customer service arranged for another dealership to check it out. No error codes and not able to reproduce the problem so they did nothing. About a month later I was one a trip on a very hilly rout. Costing down a steep section I applied the brakes as I started to be more than 10 mph over the speed limit. The pedal went about 80% to the floor! But there was braking this time. Pumping the pedal restored normal brake function. VW customer serviced had arranged for yet one more dealership to look at the car. Again, not surprisingly, they couldn’t reproduce the problem and no error codes so they did nothing. I consider this to be a significant safety problem. As VW would not fix the problem, even as the car is still under warranty, I replaced the master cylinder at my own expense and have taken the car on a 2500 mile trip with no sign of the braking problem I have more confidence in the car.

I was driving during the afternoon on a local road at approximately 30 mph. When I approached a traffic light with car brake lights showing ahead of me, I gently tapped my brakes in anticipation of possibly needing to slow down or stop. Instead of an expected gradual slowing of the vehicle, I was surprised when the brakes seemed to grab and the car stopped abruptly as if I had stepped down hard on the brake pedal. Fortunately, the situation appeared to return to normal in an instant when I let up on the brakes. The incident has not reoccurred.

The plastic button for the hand brake/ parking brake pops out of the handle which then causes the brake to release. VW has replaced the part under warranty 2 times since I purchased the vehicle. In my case the second time it happened the car popped out of gear and struck 2 cars across the street from my driveway. Dealer states its a common issue. But Volkswagen has done nothing to correct the issue other than replacing the hand brake repeatedly on the cars. It's a major safety issue in my opinion. And I feel they need to come up with a permanent solution rather than replacing with a new faulty part. I have since sold the car back to the dealer as I don't trust that the hand brake on the car won't fail again.
