Alternator Replacement Report

Alternator Replacement Report
Problem - On my way to work on Monday. Driving normally, no check engine light or any dash indicators to show a problem. As I was driving, my red "Battery" indicator came on. Seconds later, almost all indicators came on the dash. I assumed it was an alternator problem immediately since my battery was only 2 years old. Pulled off the freeway and into a large name brand auto repair for a quick check and diagnosis. Paid $27.00 for the diagnosis to tell me that the Alternator was not charging. There was no way I would ever let them do maintenance on my car anyway but I asked for a battery charge to get home. They didn't have that capability. Of course. Since my battery had been depleted a few times due to stupidity like leaving my emergency flashers on or whatever, I decided to replace the battery on the spot. I purchased the battery with the diagnostic service for $233.00. Not cheap in CA. Drove home with all systems working normally. No dash lights etc.
Next I did some quick research on this forum as well as YT to see what was involved with changing out the Alternator. Found it to be pretty straight forward with the exception of a Pulley needing to be removed to drop the alternator from the bottom. I saw a few post with horror stories of trying to get the pulley off and just didn't have time to risk that I would run into a similar situation so I called my local Lexus dealer for a price on a new one. Over $300.00 with core charge. I made the decision to just have my dealer do the replacement because of time and I also live in a condo where working on vehicles in the parking lot is not allowed. I can get away with quick things like oil changes etc., but this job was not guarantee to be quick. I got a same day appointment amazingly. Took her in where they were confused because they expected her to come in on a flatbed. ;-) I still had no dash indicators after driving for approximately 25 miles. But it did have a brand new battery also. They questioned if it was the alternator at all. I told them that I was making no assumptions since the name brand store mechanics were not what I would call a trusted source for diagnosing my girl. They took my keys and got me a loaner vehicle. 26 hours later she was done. Inspected, a few minor oil leaks that they admit are nothing to worry about. Just monitor for now. No Power steering leakage issues noted so that's a plus. Washed, tires shined up, vacuumed and all using genuine Lexus parts with one year warranty. Total cost was $563.01. They did say that the cost book stated it was an hour long procedure and it took them with all of their equipment and experience, two and a half hours. BUT they still only charged me the book labor and not for the time it actually took. All in all, I was very Pleased with this dealership. I don't say that often. My compliments have to be earned. They earned them.
So, she's back on the road with a new battery and alternator and should be issue free for years to come. Thanks.

P.S. went through the service records and see no mention of the alternator ever being replaced.

I do believe that its still a rarity for their mechanics to get their hands on an SC. She drew quite a bit of attention in the Service bay when she pulled in. But they have been nothing but square with me in our dealings in my opinion and am happy to give them a shout out.

Since you asked, I live in SoCal and it was Lexus of Escondido. The two service items I had done were programming my new TPMS sensors and now the Alternator. The TPMS programming procedure actually cost more when everything was complete. But their prices for parts were the best in my area with two other Lexus dealers to shop at.

Lexus of Westminster in Southern California earned the high mark in my opinion. They have done my airbag recall twice, both times with courtesy and professional. Even though I do not take my SC to them for service due to the cost saving, I highly recommend to those who do.

Not to butt in here but my 02 experienced the same thing at 130K or so. It had been hard to start for a couple of months before this happened but always jumped right off. No lights, no warnings, just boom, dash lights up like a Christmas tree and the motor died. We replaced a two-year-old battery and take it to the shop. Repairs were about the same as mentioned. Coming up on 5K later and no problems. I saw a big increase in MPG after replacing it. I don't know if it was related or not but it was noted.

Maybe they replaced his 130 Alternator for a 150 amp one

Could be that also. Did you know the SC had two different alternator outputs?
