Exact thing happened to my vehicle earlier this month. Left me stranded. Luckily I was in the last month of warranty and got a shiny new alternator!
Last year I had a similar experience/warnings with my 2021 RS6. Flat bedded to the dealership and they replaced the alternator under warranty.
I can\u2019t make out the sound but once upgraded the alternator on my 29 roadster pu that had a late model bronco v6 in it and the darn thing sounded like I had a super charger with the whirling. Crazy sound but ran perfectly fine for as long as I had the truck (years).
First gen Expedition- I'm not a Ford fan, but some of those old Expeditions were amazing. Definitely seem to be hit or miss, either bulletproof or a nightmare with no in between. My father had a 98 that he bought new and scrapped in 2019 with just shy of 500k miles, absolutely beat the living shit out of that truck and it just wouldn’t die, only ever needed an alternator, 2 shifter cables, a brake hose and 2 ignition coils.
Ya my alternator failed in 32k kilometers... But Audi Japan replaced it for free so it was okay ...
My alternator died in 32k kilometers.. (Audi Japan took care of it so not that bad). Otherwise the 3 lit twin turbo engine is amazing.
I love driving it on the highways, however small roads in Tokyo and small parkings are a bit challenging sometimes but the 4 wheel steering comes handy.
Wouldn\u2019t recommend unless you like spending your time on the side of the road or at the dealer. Mine just went back to my local dealer today for its 4th alternator in 32k total miles, 3rd one in the last 6 months. Literally just got the car back 5 days ago for the same issue.
Had an alternator problem (which was a recall) that completely shut down the car in the middle of driving (dash and all electronics turned off) leaving me stranded to wait for a tow truck. Audi fixed it for free.
Die neueren Generatoren sind heute noch Müll (Haltbarkeit). Musste ich erst in meinem A6 erleben (der zu meinem Glück noch auf Garantie ging). Im RS6 gehen die Dinger auch am laufenden Band flöten.
My audi B5 will absolutely refuse to use anything but OEM for the alternator
