He was talking about me and how JC1111 has a lifetime pass from me. He can even diss my Prius all he wants. Well, at least until my CEL comes back on. Jk.

Joe Z - Sorry for the confusion, I had to edit my post because I was teasing macmaster but you posted just before mine got posted so it looked like I was referring to your post. I agree with everything that you said, and also JJC1111, I don't fault a company for having something go wrong out of the gate, it happens to all car companies. I am not ruling out the IS 500 for good, I am just saying that given my situation, it may be prudent to hold off a bit until this issue is resolved to put as much odd in my favor

So mine is a 1750+ VIN and was manufactured 12/21. I only have 100 miles, no CEL.

Moonman89

I officially hit 700 miles today no CEL. I plan on my 1st Oil-Change around the 4k mark but I will be bringing in my own oil (Castrol Edge 5W-30 Full Synthetic) to the Lexus dealer once I hit the mark.

I agree nothing is perfect, and after reading this thread, I am sure Lexus will check the box and nail this for good. With all the pre-production testing my guess is a supply or bad run of electrical components is at fault here after the pre production supplies. It is possible that its a 2 part problem with the Gaskets also, but I don't think the Gaskets are the cause. From the ECU through the Harness to the O2 sensors it transmits sensitive Voltage ranges. My guess is a electronic component that is sporadic in intermittent failure in its function. Preforming ok sometimes, then not at other times. Not a simple as a fail mode that fails, and stays failed. Lexus will fix this and figure the problem. Likely they are working to test and provide a permanent fix not a possible fix, one but permanent one. Got to find the Cause and ..... Effect, and fix.

I can totally understand the frustrations the Owners are having at this time. If were me when fixed I would ask Lexus for some kind of compensation. Don't know if they would buy something like a service dollar amount credit or something for the problem experienced. I think Joe Z hit it on the Head, with the supply chain fault issue. I thought the same when I read thought from the beginning until I got to his post. Hang in there, this is a EPA related problem. They will come to a permanent fix, I'm sure.

Lol, exactly. It may hurt gas mileage by a mpg or 2 ( which no one bought this NA V8 for gas mileage anyway), and may give you 2-3 HP less, but not like it's an issue that'll leave you stranded or cause engine/transmission failure, lol! Obviously no one wants this is and doesn't want to see CELs on their new vehicle... Just no need for overreacting.
JoeZ, my dealers have no problem installing aftermarket items btw. They are actually glad to. No all dealers are super strict on aftermarket goodies and chose to lose business by not installing them. And obviously some aftermarket parts void certain warranties, but an aftermarket exhaust won't void your power train warranty, lol. If a dealer tells you that or implies that, they're Basing you and/or are trying to scare you.

You're partially correct in that Toyota/Lexus, Honda/Acura, etc. aren't infallible. You're incorrect in your conclusion that a difference in vehicle problems, longevity, durability and ownership costs and headaches are a misconception. There is plenty of data to back up the fact that Japanese cars tend to have fewer defects and breakdowns than their European or American counterparts. Looking deeper, vehicle quality metrics are tied also to make and model, not just nation of origin. There are more misconceptions about how and why these data come to pass, e.g., "German cars are over-engineered whereas Japanese cars are simple and based on proven technology", which isn't entirely true and doesn't explain the often low-tech issues that cause vehicles to fail, but the reliability and defect data are valid. Of note, one of the most reliable cars is German. Other than Lexus, Porsche has better JD Power ratings than just about every Japanese manufacturer. Mercedes-Benz, not so much, LOL.

My biggest beef lies in the way dealers and manufacturers often deal with consumers who've truly gotten a bad product.

Edit: BTW, not a flame at all. You bring some very valid points.

ExLexOwner

Yup. Porsche has crazy good reliability.

Answer

Exactly my thoughts! It totally sucks to have a CEL on a new car, but it's not like the car isn't working anymore. Heck, one could even clear the code and be good for another couple hundreads miles before it coming back.
Could be a lot worse, like batteries exploding...

You may or may not get a CEL because my vin is higher and I got a CEL at 35 miles in. I'm not trying to jinx it.

Are you able to find your production date in the display screen??

Haku415

At the moment the car is still at the dealer but I'll keep you guys posted of the situation and the production date of the car. I'm hoping tomorrow would have some good news. I'll also ask about the codes that the car threw.

Does this mean my production date is November 19?

Not sure what the JD Power report looks like, but real world feedback from Porsche owners would suggest otherwise.
Let's assume JD is right, we should all sell our IS's and buy Porsche's...oh wait, there's that whole 'sticker price' thing.

I think I'm good driving my 7+ year old IS...and looking forward to my next IS...or worst case something in the Lexus/Toyota family.
