Just something you have to deal with as the alternator deals with heat cycles, mileage, and age.

The car itself will last much longer than 120k. The powertrain is relatively bulletproof (although, people tend to do have trans issues when mileage starts getting up there if they beat on it/ignore fluid changes), it should easily exceed 200k. There are quite a few people on here in the high 100s/200s at this point.

Should I or wait?

Soccer moms beat the heck out of the 2GRs in Siennas and Highlanders and can't seem to kill them.

As others have mentioned, there are, of course, items that are considered wear items that will require replacement at some point. Alternators, batteries, water pumps, etc. Suspension is a highly overlooked area. The suspension starts to display symptoms around 200k, maybe less, depending on how you drive, where you live, etc. A friend of mine has a 1998 Land Cruiser with almost 200k miles. He's maintained it well and it still runs like new.

I just bought a 2010 IS350 with 106k miles. I consider it barely broken in.

I love driving this car, better than any car I have driven before (Genesis, Avalon, ES350, RX 300). I purchased insurance on it after the last service and they have agreed to pay for the oil leak
I am worried if this car should be a keeper. Did I buy a lemon, is it my driving habits or this is all normal
thanks

I only drive it to work which is close to my house now, so I don't even get close to the miles for each service appointment, I do it by date.
A few months ago, my car did die on me for the first time. The alternator went out and killed my battery too. I got those replaced and everything is running good again.
How much more can I safely get out of my car though? I was hoping to maybe reach 120k or higher ?? Maybe 3-4 more years ?? I have no idea.
Anyone else have any ideas for my car? Do others have more miles and are running fine? Any big issues?

Thanks!!
