The alternator failed causing the vehicle to shutdown in the middle of traffic. I was on a surface road not the highway so I was able to get local police to assist. When it failed there was no car electrical system function, so I could not even turn on my emergency blinkers. This is apparently very common on Audis, as the same part was used to replace the alternator-??. It took a month for the dealership to get the part in stock.

While driving in heavy traffic on 12/23/22 the entire electrical system shut down and all power was lost. Fortunately I was not hit by another vehicle and coasted into a parking lot with no power. This is very dangerous. Per conversations with the dealership and with Audi (1/10/23), alternators on thousands of vehicles are failing (possibly due to a software issue). The vehicles are sitting on dealer lots and in driveways useless. Audi online forums confirm this as well. There are no alternators available. No recall has been issued and no warning of this unsafe situation has been made by Audi. Per the dealership, they are largely in the dark as well as there has been no meaningful communication by Audi. Someone will get hurt when their car dies on a highway. People are paying thousands for their cars to be undrivable. Audi dealers will not trade the vehicles because they are effectively worthless until repaired.

The Generator (Part #: 4N0903028P) failed causing the car to shutoff while driving. This is a known issue by Audi as it has issued a TSB. Further steps must be taken by the OEM to ensure safe operation of the vehicle by its owners. This is a safety issue that must be resolved soonest!

I'm very upset with NHTSA and Audi. I submitted a complaint with NHTSA on 10/22/20 and the complaint number is 11365744. Again as stated in my complaint this is an actual safety issue. I then took the vehicle into the dealership for them to look at the problem. Well it turns out that the dealership's service department has had a number of complaints just like mine. It also turns out that Audi has a fix for the problem. The fix is a software update 37M6. I'm glad the issue has been fixed on my vehicle but the real issue is that NHTSA and Audi are aware of this fix but both of these entities are not requiring the fix to be made via a gov't issued recall. Audi calls this fix a "campaign". Audi is avoiding the standard practices of NHTSA by referring to this problem and fix as a campaign which is outside of the normal technical service bulletin and safety recall process. Has no one at NHTSA or Audi learned the lessons of the GM debacle with the ignition switch. This cover up by NHTSA/dot and Audi is a complete an utter disgrace. To allow Audi to operate outside of the NHTSA system is a complete failure. NHTSA needs to mandate Audi issue a safety recall asap!
