thank you, I appreciate it

 

Mine just failed a few weeks ago, 120k Replaced myself

 

What are the symptoms of an alternator thats failing?

 

If I remember correctly mine went out around the 8yr mark. Replaced with a lifetime replacement warrantied AutoZone reman unit. So if it happens again, back to AutoZone for a free replacement.

 

2007 IS250, 150k miles. No failure yet.

 

07 IS250

Failed at 170K

 

06 IS350, 165k, original alternator as far as I know. P/O took to Sewell Lexus for every tiny thing. Not shown as ever replaced, still works great.

 

My 06 250 died at 120k

 

when I had my 07 IS350 after 180k on the odo, had one fail, idk if this played a part but had a large amp powering a sub for most of that time too

 

My '06 IS350 failed last year at around 80,000 miles. No warning. Took out the battery as well. Had it towed to the dealer for new alt. and battery. Never, ever have I had an alternator fail without ample warning and I've owned many, many cars over the past 56 years. Ahhh, but it's a Lexus, right? So all is just fine.

 

06 is250 with 150k miles. No fails and I've had 1500w RMS amp powering my sub since 95k miles.

 

Mine slowly failed at 145k. Replaced at the dealer. They picked up the car with a flatbed.

 

2008 IS250 with 78k miles and no failure yet.

 

Mine failed at 10 years 110K.

 

reviving thread. had my alt replaced by Lexus in 2013 at around 80k or so and it might be going out again at 111k. i'll know for sure monday.
