Well it looks like I'm getting rid of the car. No clue what's wrong with it. I'm picking up a potential new vehicle this afternoon. What a disappointment.

My car is still at the dealer. It's been in service since July 9th. I've been dealing directly with the service manager who has been great but we're just not finding the answers as to what's wrong with the car. The dealership is working with me to get me out of the car but I still haven't heard from Lexus corporate what they want to do. Hopefully I'll hear something this week.

Wondering if this has anything to do with the latest recall for valve springs.
http://www.lexus.com/recall/#hs3RecallSection
Lexus announced that it has informed the National Highway Traffic Safety Administration of its intention to file a Defect Information Report (DIR) regarding approximately 138,000 Lexus vehicles, powered by 4.6 and 5.0 liter V8 and 3.5 liter V6 engines in certain 2006, 2007 and 2008 GS, IS and LS models in the U.S. The formal report will be filed the week of July 5.
In the covered vehicles, due to slight variations during the manufacturing process, some foreign material may have contaminated a small number of the valve springs. If a vehicle is affected, there is a remote possibility that abnormal engine noise or idling may occur. In extremely rare instances, the engine may stop while the vehicle is in operation.
Lexus estimates that the likelihood of a customer vehicle experiencing this condition is two-tenths of one percent (0.2 %). Lexus has received no reports of accidents or injuries related to this condition. No vehicles from the current 2010 model year nor 2009 are affected.
Lexus will send owners of the involved vehicles a recall notification via first class mail. Owners are requested to contact their local Lexus dealer for diagnosis and repair after receiving their notification. The repair will involve replacement of the engine's valve springs at no charge.
Owners can continue to drive their vehicles. If symptoms are noticed, such as vibration, rough idling, unusual engine sounds or poor performance, the vehicle should be brought to a Lexus dealer for service.
Certain Lexus vehicles produced among the following models and years are covered:
Model
Model Year
GS 350
2007 2008
GS 450h
2007 2008
GS 460
2008
IS 350
2006 2007 2008
LS 460
2007 2008
LS 460 L
2007 2008
LS 600h L
2008
Customers with questions or concerns should contact the Customer Experience Center at
1-800-255-3987.
Crystal, maybe it would be worth a try to call the number with your VIN and see if your car is part of this. Please keep us updated. Good luck.

I've already looked into Lemon Law. Sadly, my situation doesn't qualify. I purchased the vehicle used with 3300 miles on it. It was previously a Lexus company vehicle. Also the first time the problem was acknowledged was just over 12k miles. The cutoff is at 12k miles.

This valve spring recall has also been performed on my car even with it being a 250. But this isn't the answer either. Looks like my car is headed to the auction block.

So after 3 months, Lexus purchased my vehicle back. The diagnosis was inconclusive but they feel it was a problem with carbon. My car is now a research car, hopefully they can get a handle on the design problem causing this issue.
Now to find a new car!

What computers does the lexus use? From the flintones era? Shame on them.
My 2003 (other brand car non lexus/toyota) recorded misfires with the cylinders every time. The resolution was either Spark plugs or ignition coils. There is no more "mystery" to misfires, especially on a engine with so low miles.
