Audi A6

"Brakes were grinding and throbbing from the time of delivery. Dealer attributed this to "Audi's big brakes." At 15000 miles the front brakes had to be replaced. Initially, the dealer attributed this to normal wear but then agreed to waive the cost of replacement. The replacement brakes are fine"

"I had to replace both front brakes at 12000 miles which seems excessive to me and after 27000 they want me to replace the rear"

"Rear Caliper seized. Rotor required replacement."

"I bought the vehicle in May 2019. Three months later the rotors had warped and needed to be replaced. This was my second A6 so i know who to use the brakes, my last A6 went nearly 60k miles before I needed rotors replaced. After much arguing, the dealership agreed to replace the rotors on their dime (otherwise what does certified pre-owned mean?). Less than three months after the replacement, the rotors began vibrating again and will need to be replaced soon. Something is fundamentally wrong with the system"

"Front brake pads needed to be replaced at about 19000 miles. Dealer replaced brake pads at no cost."

"The Audi brakes do not last. I have had issue with the brakes grinding and shaking the car. Have replaced the brakes twice already and only have 50,000 mile on the car."

"warped rotors. Audi did not offer to fix. Happens all the time when slowing from higher speeds"

"car devolped harsh pulsation soon after purchase. I had a number of complaint all of which was fixed promptly under certified warranty."

"2nd time brake rotors were replaced in 25000 miles."

"Uneven wear of the rotors, which had to be replaced to solve the problem"

"Brake rotors were turned about 36 months ago for the same pulsating problem. Now need to have it done again. Seems to be a recurring problem with the 2016 Audi A6. The service Tech did not disagree with me when I sted so."

"Best sedan on the market bar none...I just have issues with pulsation and warped rotors. Three different times before 20K miles. The dealer keeps repairing them under warranty, but it doesn't take long for the issue to come back. I do not have many hills and I do not ride my brakes, and I even drop the trans into sport mode to slow down the car. People on line say its the electronic parking brake, which is activated as soon as you get out of your car when it's running (getting mail) pushing on the rotors? But, it happened on front also..."

"Vehicle was a stop sale Turbo Diesel A6 and due to 'Lot Rot the brakes became rusted and pitted"

"At 10,000 miles the rotors failed and had to be replaced. Audi service said that it was because I had used the Adaptive Cruise Control in the mountains, and that the Adaptive Cruise Control had put too much wear on the brakes. I live in the mountains, and the Adaptive Cruise Control was the primary reason for having chosen Audi over other brands. At first Audi Service advised me not to use the feature in the mountains, and then they relented and said to try using the manual transmission control"

"This was the second time that the rotors warped under regular use. The first was at 15,000 miles. Both times were covered by Audi. This last time the rotors were on back order so took a month before a repair was made. Car was operational but braking was impacted by warped feedback."

"Front rotors warped and had to be replaced."

"The A6 was in the shop for warped rotors 3 times for the first 16,000 miles. The car was returned to Audi today for a soft brake pedal. It almost goes to the floor and will only come back after the second pump. I don't think they bled the brake line properly."

"warped front brake rotors -- started after only 12000 miles on the car. Design or manufacturing flaw. Common problem, and Audi definitely knows about it. Audi replaced mine for free but is not doing this for everyone (which I don't understand)."

"I am on my fourth set of rotors in 48k miles. Rotors seem to warp rapidly, especially if you commute involves rush hours highway driving. Apparently the rotors don't dissipate heat well enough and warp under stressful use. The dealer has replaced them but Audi USA does not accept this as a design flaw. It is. Recently replaced with nonAudi brakes that are Less expensive and heavier than the OEM. Perhaps the lighter weight contributes to the rotor heating problem. New brakes working well but only 1k miles so far...."

"Rotors had to be replaced at 18000 miles and again about one year later. Very premature wearing"

"Replacement 2nd time may be due to the dealership not replacing the pads the first time the rotors were replaced"

"brakes pulsated going down hills etc., started with only 19000 miles on car. told roters needed replacing at cost of $800 and audi would not cover even though car was under warranty"

"At 28000 miles each of the 4 rotors test out of spec. I replaced all 4 for $1,500. The full warranty is in place but Audi said brakes are only covered for a year. Besides, the service rep said, most people only get 30,000 miles so your wear is normal. By the way, there was very little wear on the pads so the brakes were not used hard. Poor performance on the brakes and poor attitude on Audi saying 30k is normal and acceptable."

"It appears the rotors are not large enough for the weight of this car. They wear rapidly and groove severely."

"The systems often does not connect to the smart phone in the car that has been previously paired. Manual connection is required."

"Responses to the exact same voice commands are inconsistent. Compared to Google and Siri, the system is very complex and not intuitive"

"The system is designed to allow one to send an address from a PC to the Directions mode of the navigation system. After years of trying, they have given up on fixing it."

"The navigation system almost always had a destination which did not relate to the one I put in. After many service calls it was never fixed. Terrible service."

"The phone, Samsung Note 4 with Verizon will pair OK. When driving and talking, the car will loose the connection with the phone and the radio comes through the speakers. But the phone still has the caller active. I can't hear the caller because the phone thinks the Bluetooth is still connected. After 10-20 seconds, the voice comes back on the car speakers. The car call timer resets to zero, but the phone timer shows the total length of the call. My phone works fine in my MERCEDES-BENZ and my girlfriends Mercedes. The phone has the same problem with service loaners from Audi. I have had it in 3 times and they claim they can't find any problem. I can't count on it to make business calls."

"making phone calls"

"Turns on when backing up"

"Radio cuts out often. Horrible system"

"antenna failed twice in 6 months"

"XM radio was cutting out. This was a known bulletin and required removal of ceiling liner to fix connection at antenna. This was covered under warranty. ."

"Volume stopped working and the speakers sound was bad. They had to replace the entire console."

"switch for on and off does not work most of the time . .but I have found a work around"

"Radio stopped working. After several days of analysis the dealer had to order a new antenna module. Replaced under warranty."

"The radio presets don't stay set."

"See prior answer."

"Totally useless. Never works. Also, loads of other problems in car"

"When I leased the car the navigation system did not work. Dealer told me to bring in for a fix. They said no problem. Problem persisted till now. Never fixed. Phone system goes to navigation when tried by voice. They can’t fix it. Flashing lights to show car in blind spot doesn’t work. They can’t fix it. Radio shuts of in tunnel. Worst car I ever had."

"Unable to use fone or navigation system by voice."

"Line into radiator either failed or wasn't attached properly. Had to have vehicle towed to dealership to correct problem."

"rattle in dash board"

"The rear shade rattles when it is lowered while the car is moving."

"Rattle in the pop-up display when drive over rough surfaces, which is quite common on the island of Oahu, Hawaii, where I reside and operate this vehicle."

"Low level rattle in the dash area that's there for a while then goes away to return sometime later. It's quiet most of the time."

"noise is louder then expected around windshild"

"Apparently there was a hole in the rubber sealing that seals steering rack from the firewall. It took over a year and ~7 visits for the dealership to figure this out, which happened after I threatened the dealership that I will file the car as a lemon, by then the factory rep visited to take a look"

"simply much more road noise than friends who have BMW or MB vehicles"
