Not just that they are cracking down on their parts as well. I can no longer get brake pads or rotors at OReillys or AutoZone. I was forced to use crappy knock offs for the same price as I couldn't wait on ordered parts.
Went through the same thing with a recent starter replacement. They no longer offer OEM bosch (this was oreilly not sure about AZ) and they no longer sell Bosch OEM even remanufactures.
Again they explained to me this was due to BMW themselves.
I'm going to ride my 328i into the ground, but once its repairs outweigh the value of the car (doing the repairs myself now, had to become my own mechanic to avoid a $1700 bill and 2 week wait for a starter replacement),I am never touching one of their vehicles again.
When in the dealership in Seattle 2 years ago for an oil change and fluid top off/inspection it was a horror show.
They only added about 3 quarts of oil to my car out of the almost 7 needed after a change (light came on immediately as leaving and oil level was - null-). They never did their whatever-point inspection, never did the fluid top off, and left my oil filter cap loose! My 'account manager' was supposed to go over some stuff with me- never saw him. Was told he'd left notes on my file- did not.
While waiting I saw three different people come in with problems with their EV batteries no longer charging. The 1st two were told they'd be covered under warranty. I heard the reps talking amongst themselves about how bad it was getting and whether there would be a recall. 3d person was a lady who was pissed as she'd just had her battery replaced under warranty, it'd happened again and this time they wanted her to pay for a new one. She threatened to sue and they comped everything they could think of for her.
Now with this heated seats fiasco BMW has officially nuked the fridge.
Edit to add- if anyone is interested check out the starter replacement [1], absolutely fucking ridiculous the way cars are now engineered to stop the layman from affecting their own repairs.
Used to be starter replacement was something anyone could do and was all of two to four bolts and a wire and took ten minutes of time. You could even just replace the solenoid half the time for a few bucks.
I've now replaced brakes, rotors, control arms, shocks, struts, starter, window actuators, headlights, radiator, mass airflow sensor, ECM, spark plugs and ignition coils, cleaned the O2 sensors etc. Some of the steps are insane especially the radiator which was 600 just because California ones have a stupid sensor on them that cant be used on an off-brand radiator.
So much blood and sweat because why leave room to work on anything.
Seriously fuck BMW.
