2018 Audi Q5 Brakes Problems

Problem with Brake booster servo issue comes on the dash then goes away. Brakes are spongy and brake pedal makes a swooshing sound when pressed

recently on a number of occassions the car stopped because the pre-sense sensor went off prematurely. There were no cars within 500 feet of my car on all occassions. Now the Pre-Sense has completely turned off and will not turn back on

I was trying to park my car in my office parking space, after right turn to parking space, I applied brake to stop, but the car suddenly accelerated and within few seconds it crashed into the office building. I was still applying brake when it accelerated and I could not do anything else. The fact that vehicle climbed two levels of curbs to hit the building shows that the acceleration was out of my control. And even vehicle's collision system did not kick in when car was climbed over the curb. Polic report #: 22-350-0239C Agency: SCCSO

While driving at a relatively low speed, approximately 30 mph, I approached a red light and proceeded to slow down. The brakes did not engage, so I continue to pump them but had to swerve into the right lane to avoid hitting the car in front of me. Fortunately, there wasn’t a car in the right lane. It was raining but not heavily, although earlier we did go through heavy rain on the freeway. After this incident we still had to drive about 5 more miles to get to our destination. The brakes worked the rest of the way. I took the car to Audi to have them check it and they said they didn’t find anything; however, this was certainly some sort of brake malfunction.

WHEN PRESSING THE BRAKE PEDAL AT TIMES YOU HEAR A METAL CLANG SOUND LIKE SOMETHING HITTING A TIN CAN. THIS HAPPENS OFTEN BUT IS NOT CONSISTENT. I HAVE VIDEO EVIDENCE OF THIS AS WELL AS HAVE SEEN THIS ITEM DISCUSSED IN DETAIL OF AUDI FORUMS. AUDI CLAIMS REGARDLESS OF MY EVIDENCE NOTHING CAN BE DONE. MY CONCERN IS IT HAS TO DO SOMETHING WITH THE BRAKE AND TO ME IS A SAFTEY CONCERN*DT

I HAVE REPORTED TO SEWICKLEY AUDI, MY CLOSEST DEALER, ON SEVERAL APPOINTMENTS THAT MY BRAKES SEVERLY GRIND UPON APPLICATION. I WOULD BELIEVE THAT THE ROTORS ARE SEVERLY SCORERD OR WARPED. IT HAPPENS UPON FIRST USE EVERY DAY, AS WELL AS A LOUD GRINDING UPON EVERY STOP ESPECIALLY FROM HIGHWAY SPEEDS. I HAVE BEEN TOLD THERE IS NOTHING WRONG WITH MY BRAKES ALTHOUGH I COMPLAINED FROM MY INITIAL VISIT , MY LAST INSPECTION AND RECENTLY BROUGHT IT IN SPECIFICALLY FOR THAT. THE NOISE/ GRINDING IS BAD, BUT THE LACK OF QUALITY BRAKING HAS ME MORE CONCERNED. I AM GOING TO TAKE IT TO "MIDAS MUFFLER" OR SOMEONE ELSE TO CHECK. I BELIEVE OTHER Q5 AND CROSS LINKED VOLKSWAGENS HAVE CALIPER PROBLEMS AND I BELIEVE MY CAR DOES AS WELL BUT THEY ARE UNWILLING TO REPAIR IT UNDER WARRANTY TO SAVE COST.

THE VEHICLE WAS STOPPED AND I WAS INTENDING TO TURN LEFT AT A SIGNAL LIGHT. WHEN THE SIGNAL CHANGED FOR ME TO PROCEED I ACCELERATED INTO MY LEFT TURN WHEN THE CAR SUDDENLY BRAKED ON ITS OWN AND PULLED ME BACK INTO THE SEAT. THE AUDI SENSE INDICATOR CAME ON BEING ACTIVATED AS IF IT SENSED I WAS ABOUT TO MAKE IMPACT WITH ANOTHER VEHICLE. HOWEVER, I WAS THE FIRST VEHICLE TURNING LEFT AND THERE WERE NO OTHER VEHICLES IN FRONT OF ME NOR ANY OTHER VEHICLES OPPOSITE OF MY LANE OF TRAVEL SO THERE WERE NO VEHICLES ANYWHERE NEAR MY VICINITY THAT SHOULD HAVE TRIGGERED THE AUDI SENSE. THERE WERE NO VEHICLES BEHIND ME ALSO TURNING OR I'M SURE THEY WOULD HAVE REAR-ENDED MY VEHICLE GIVEN THE SEVERE BRAKING ACTION. THE SYSTEM INITIATED A SEVERE BRAKING ACTION AS IF I WAS ABOUT TO REAR-END ANOTHER VEHICLE. THIS OCCURRED ON JUNE 14, 2018 AT AT APPROXIMATELY 10:30 AM. WEATHER CONDITIONS WERE WARM, DRY AND CLEAR WITH NO PRECIPITATION. I BELIEVE THIS WAS CAUSED BY A MALFUNCTION IN THE AUDI SENSE CAUSING THE BRAKING SYSTEM TO INITIATE.

SQUEALING BRAKES AT SLOW SPEEDS. DEALERSHIP ABLE TO REPLICATE ISSUE BUT UNABLE TO RESOLVE ADEQUATELY. THEY ASKING US TO REPLACE ROTORS AND PADS WITH SEVERAL HUNDRED DOLLAR COST TO US. CAR IS ONLY 2 YRS OLD NOW. WE BOUGHT CPO AFTER CAR WAS USED BY DEALER SALESMAN FOR 6MO. BRAKES HAVE BEEN SQUEALING SOON AFTER WE GOT THE CAR.
