I drive a Cadillac SRX 2011 approximately 77000 miles. A few times I have experienced a soft brake almost to the floor after hitting a bump. This is so scary because it felt like I was not going to be able to stop the car. The brake comes back afterward as if nothing happened. It is so frustrating when the mechanic can’t reproduce this issue. It angers me that Cadillac has ignored complaint after complaint for this issue along with headlight moisture and roof drainage issues among a few to name.

The brake issue is a safety issue that could cause serious crashes involving failed brakes and Cadillac has ignored the complaints. It is helpful reading other common complaints such as the soft brakes and how customers tried to resolve the issue.

When it is how out, over 85°F the brake pedal becomes hard to press with very little assist, and all four wheels have the breaks applied. So the break pedal becomes hard to press while the breaks engaged and cannot disengaged them even after turning off the car and restarting the car. The only way I was able to disengage the brakes was by leaving the car overnight to cool off; alternatively, after some troubleshooting, removing the vacuum hose off of the break booster (removing the vacuum) will disengage the brakes, curiously. This is where my limited engineering knowledge left me scathing my head. Could be the a dirty poppet valve not closing on the driver side, allowing atmospheric pressure to push constantly?
