While driving the car I press the gas pedal and it loses power or won't accelerate at all, then all of a sudden something happens and it lunges forward fast it is scary I have almost crashed 2 times. This issues is intermittent, thus the driver has no control of when the car is going to drive properly when I doesn't it is scary. I'm have been relegated to 45 miles an hour on the freeway I cannot control any part of the car to ensure I can make a lane change if I need to to overt an accident. The reason I'm filing this is because Audi has known about this since at least 2010, there are TSB'S FOR EVERY YEAR REGARDING THIS PROBLEM EITHER EXACT OR a slight change of this problem because every car is different. Meaning how it's driven to where it is located and weather issues. AUDI HAS PREEMPTED THESE Issues bY stating the problem I'm having a long with thousands of others is a PERFORMANCE ISSUE BUT THIS IS WAY MORE THAN THAT. IT IS Definitely A SAFETY ISSUE WHEN YOUR CAR ALL OF A SUDDEN WONT ACCELERATE. THIS ISSUE CAN REMAIN FOR 45 MINUTES OR Literally A SECOND. THIS IS A VERY DANGEROUS SAFETY Problem AND IF THEY MEANING AUDI HAD NOT HAD KNOWN ABOUT THIS PROBLEM FOR OVER A DECADE AND CONTINUE TO MAKE THESE CARS THE SAME WAY THEN I WOULDN'T HAVE HAD TO MAKE THIS REPORT IF THEY WOULD HAVE PUT THIS UNDER SAFETY AND NOT PERFORMANCE AND PREEMPTED A INVESTIGATION CIRCUMVENTING THE NTSB'S AUTHORITY BY PUTTING OUT A TSB BEFORE IT CAN BE INVESTIGATED. THE dealership REFUSES TO LOOK AT THE TECHNICAL SERVICE BULLETINS WITHOUT A COINCIDING CODE, BUT THE SOFTWARE UPDATE DOES NOT STATE A CODE WITH IT BECAUSE IT'S FOR DECADES OF AUDIS. THE SOFTWARE UPDATE WILL FIX MY CAR AND I CANNOT DO THAT MYSELF SO I HAVE AN UNSAFE CAR. Also the dealership is refusing to update my software as Audis TSB CLEARLY STATE ALL AUDIS FROM 2002 TO 2025 NEED THIS SOFTWARE UPDATE FOR PROPER REPAIR OF ALL AUDI VEHICLES! The Dealership is refusing give me the warranty documents & recalls done.

2014 AUDI A5. CONSUMER WRITES IN REGARD TO SAFETY RECALL NO. 80C5, 19M1, 19N4 AND PARTS FOR THE REPAIRS ARE OUT OF STOCK. *AS *JS
AUDI OF SEATTLE CONFIRMED 1/22/2018 THAT MY CAR IS FUNCTIONING AS DESIGNED, BUT I BELIEVE THIS DESIGN IS UNSAFE AND UNDESIRABLE. SPECIFICALLY, WHEN DRIVING IN REVERSE USING THE BACKUP CAMERA VIEW, IF I RECEIVE AN INCOMING CELL PHONE CALL TO MY PAIRED PHONE, THE CAR PRIORITIZES THE TELEPHONE SCREEN VIEW OVER THE BACKUP CAMERA SCREEN VIEW, WHICH IMMEDIATELY DISAPPEARS. BACKING UP IS OF COURSE A TIME WHEN THE DRIVER'S ARMS AND HANDS ARE NOT WELL POSITIONED TO POKE THE "IGNORE" BUTTON ON THE PHONE SCREEN.
