Mine Just Died 07 136k IS350
Drove her back on highway, car shutoff close to home, everything went black and I was driving at 40 MPH, Steering wheel and brakes where working great and I managed to park safely !
However when stationary you almost lose power-steering without the alternator working. Keep in mind I was driving with lights off when ever possible, and all accessories were off. It was charging when throttle is pressed but not in idle, very weak.

Mine died at 155K when i purchased the car. As others said, the hidden bracket made it tricky, and I also pulled a wire from one of the camshaft sensor connectors during the replacement.

Mine died last week 2007 IS 350, only 36k miles. Had it replaced with a rebuilt one at the shop, and also put in a new battery. Now, the steering wheel feels a little more firm than before. Any idea what the problem might be?

Bought mine @ 89K imported from owner in Cali. Just hit 150K and alternator seems to be hanging in there. I’ve had to replace my battery 3 times over the past 3 3 years of ownership. (Car died 2 hours after leaving dealership, they replaced for free, then had to get another about 1 year later.) Just replaced battery 3 days ago after a long trip in CO, and everything seems back to normal. Will update if anything happens haha.

IS350 @ 110K, “Battery” Light on the dashboard. Put the tester across the battery while running only measures 11.9V. Should be 13V+ so it charges the battery.
