Agree but Lex dealer is another towing and total cost will end up significantly more. Mechanic i am at now is recommended by local friends. He quoted Denso part and his software did show the 6.1h labor.

Agree on all counts, taking care of the rest can wait. I did see the 6.1h on his screen along with the proper car info. Based on circumstances and fact that he is recomended, I'll have him do it and cross fingers all goes well- we will see.

A bad starter alone will not cause this.

-------
I replaced my LS460 starter a few years ago on my driveway with hand tools by following this ClubLexus member's instructions: Post 22 of ls460 starter ? - Page 2 - ClubLexus - Lexus Forum Discussion. It took me about 6 hours. The procedure was not difficult but needed patience. I used the Denso starter from Rockauto (about $160) More Information for DENSO 2800370 (rockauto.com), plus a few gaskets from the local Lexus dealer. If you are handy, you may do the work yourself.

You need to check the battery’s State-Of-Charge to see if it has enough energy to start the engine. The battery may be just discharged. Before you start on the starter, you should try a battery that you know has an adequate charge.

You are correct; I saw videos on YouTube potentially showing how to install an LS460 starter replacement in as little as "6 minutes" however, sadly, and unlike you, my DIY abilities end at attempting to order the best part:-) I got the mechanic to buy a Denso part (at least), but doing it myself was out of the question:-(

I agree, and as I had just installed a brand new costco battery stamped "09/23" more than a week before, I instantly rejected the battery as the source of the problem, because at the time of the failure, I first attempted to jumpstart the LS with another car, but in vain. As a result, I "narrowed it down" to the starter because the dashboard was powered properly and even jumpstarting with cables didn't help, indicating that the battery is working properly (since it is still charged after more than a week of use) and this issue is not related to a battery or/and alternator failure--hence the starter, particularly because of the clicking sound when you try to start the engine.

Here is the costco battery that I installed over a week ago: https://costco.interstatebatteries.c...183&Country=US , stamped "09-23" and it has been functioning since as expected, so I don't think the battery is the problem. But only time will tell, especially if this replacement of the starter is the only action needed to be taken - or not..

Thanks but I want to see the condition of the terminals. What some people consider great condition isn't. Your description of a no start can happen when the terminals flake out under heavy load I'd hate for you to replace the starter and find out it wasn't the cause.

I did check the terminals to make sure none had come loose, but they were both secure, and I use the red and green rings to prevent corrosion. I concur that the terminal might be the source of the problem, and I've also read that an electric harness coming loose can also result in this kind of problem. I rolled the dice and it is being "fixed" because it happened 50 miles away and I'm not good at do-it-yourself projects. We'll see when I pick it up next week.

Again, I want to thank you all for your wonderful feedback. According to the clicking sound, something went wrong at the starter level, even though the battery is brand new and even jumping it didn't help. I hope it gets corrected properly.

I agree with several others here that the starter is probably not the problem. My starter went and when I pressed the start button I got nothing.

That clicking sound is text book for not enough juice getting to the starter motor. I would start with the battery. For cheap money you can get a charger that also has a power setting that will produce enough to start the car. As far as the terminals, whenever I have changed batteries I also use fine sandpaper and scour the inside of the terminals. They may appear clean, but a thin clear film can form that limits the connection from the battery.

And yes, it is a labor intensive job to change the starter motor. I remember when mine failed I told the flatbed truck driver that I knew it was the starter motor. Trying to be helpful he said "let me get my hammer and rap it a couple times". I laughed and said good luck with finding it!

LS2k

That's what I initially thought—not enough power to start the engine—but my car has been running smoothly ever since I installed a Costco battery less than ten days ago. First, I tried using my standby quick charger, checking the battery terminals to see if any had come free, and then even getting someone to jump start me using cables, but to no avail—the starter still won't crank. I'm not sure if it was a bad starter or something else, but because I was stuck 50 miles away, I had to get it fixed there. I picked it up today, and yes, it did start correctly—for the time being, anyhow - time will tell.
