I think every taxi I've been in has had the ABS light on! Is there a real problem with North American car ABS systems that causes them to die far before the rest of the car? Air Conditioning seems to be the same way...not worth fixing.
I've had two GMC work trucks with dead ABS systems. One had a cut wire to a front wheel so I can't say that GM was at fault. My boss wouldn't fix it and I ended up jacknifing the truck. I feel that the ABS system locked the wheels on me and wouldn't let go...I may be wrong.
The other truck had a night time failure. The battery was dead in the morning so we charged the truck. The ABS pump was growling so I pulled the ABS maxifuse and all was well. Dunno if the boss fixed that one either...I had to return to school the fall.
