I recently purchased a CPO 2018 Audi Q7, and shortly after purchase, I encountered the problem indicated in this TSB about break squeal (https://static.nhtsa.gov/odi/tsbs/2018/MC-10153128-9999.pdf) I contacted the dealer (Audi North Austin, located at 12971 Pond Springs Road, Austin, TX 78729) to fix this problem, but was refused because my car does not meet the criteria specified in the TSB, namely 24 Months / 24,000 Miles (my car has 27,700 Miles). In doing so, I found another TSB (https://static.nhtsa.gov/odi/tsbs/2018/MC-10153129-9999.pdf) with the same problem as in my car. And it has different criteria, namely 48 Months/50,000 Mile. In this regard, I would like to ask why there are different criteria for the same problem" Why are 2017 Audi Q7 models has 48 Months/50,000 Miles to fix this problem, but 2018 Audi Q7 only 24 Months/24,000 Miles "

Loud squeaking noise when backing up/on reverse coming from front brakes. Advised Audi dealership at rocherst hills, mi for the issue when the car was less then 2 years old and with only 20,000 miles on it, but service adviser said there was no bulletin tsb, service campaig or recall for the the issue. I should pay out of my pocket for the service. After speaking to an Audi representative directly, I was advised that there was a tsb for the car and my car it should be serviced. When contacted the same dealership I was advised that I was out of 24,000 miles (by 1,000 miles) or 2 years warranty (out 4 months) and they could not fix it. When I complained to them that the other advised told me there is no coverage available, when my car was under coverage limits, then the dealer told me that the adviser dos not work with them anymore. I opened a complain with Audi customer care and after 2 weeks, Audi customer service stated that the dealer advised that I need to replace rotor and pads due to dust'.. Audi could not do anything as they have a relatioship with the dealership, as per customer service repersentative. The squeaing is very, very loud, my 3 kids and people around get scared or wondering what is happening when I press brakes while on reverse. Neither Audi usa or Audi rocherster hills, mi care about their customers safetybut just our money.

Front brakes have issues from the beginning with brand new tires from the dealer. Dealer changed all tires with brand new tires again and brake pads for front brakes six months ago. Vehicle makes noise when I push brake. Vehicle is now with the dealer and they are trying to figure out. This is not at all acceptable being a $80K vehicle. Audi should discontinue these defective vehicles and refund the money. This is also a road hazard and risky issue to drive. This is a major safety issue.

Loud squeaking noise when backing up coming from brakes. Noise is alarming and causes one to immediately brake, and noise dramatically alarms those around and in vehicle. 2018 Audi Q7 with 26K miles. Dealer did not advise of tsb advising self...only aware after calling Audi directly. Dealer service advised brake and rotor replacement if problem continues. Internet research reveals problem existed since 2016 Q7 model. Audi never informed us directly and dealer service did not inform us...we needed to call and or inform both before being advised of tsb. NHTSA called and informed self of Audi's decision to not do recall and only issue tsb. Where is the responsibility for advising vehicle owners of such problems.... dealer service rep did not advise of tsb initially...owner advised to repair and absorb cost. Once tsb discuss by owner, arrangement was made for cost sharing.

Audi has a pre sense feature that will automatically slam on the brakes. It fails constantly and slams on the brakes at various times. So far it has been at slow speeds, but someone is going to get killed by this feature. There is no way to automatically turn it off, and it turns on every time you restart the car

I was taking a U-turn under a freeway in my 10 month old Audi Q7. As I was finishing the U-turn a stabilization error message appeared and my brakes went out. I was finishing my uturn and couldn't slow down soi ended up running into the cement barrier with my right back wheel and went onto the feeder. Luckily it was at 5am so no other cars were on the road. Hitting the barrier slowed by car down to 5 mph. As I straightened out my car, the brakes started working again. I had the car towed to the dealership. The dealership said Audi of America had to look at it. The engineer finally came to look at it on Jan 3rd (3 weeks after the accident). He said that they couldn't test drive the car because the control arm was broken but the tests they ran showed that nothing was wrong with the car and told me to call my insurance. I asked how they knew nothing was wrong and they said tests were run. I asked how they explained the error messages (stabilization error and safety error). They said those came up after the accident. They don't the time of the accident so how do they know this?. I took pictures of the error messages and know the timing of that. I asked for a print out of their findings 3 times. It has been 10 days and I still have not gotten anything from them. The car is still sitting at the dealership.

The brakes have squealed since 3K miles. No matter the weather conditions may be. We have been told that is normal, but I am researching otherwise. At 5am leaving the home, the brakes squeal, at 2pm squealing, 5pm squealing, midnight squealing. For being a luxury vehicle I love and trust, this makes me extremely nervous and embarrassed when neighbors are out and hear this squealing. The brake foot pedal does not glide when being used. The steering wheel has a locking motion when being used on turns.
