2006 GS300 has a timing chain not a belt and needs not be changed. steviej

need three things to start the car. spark, fuel and air. you replaced battery but did anyone check the cables to make sure ground connection was secure and clean? To me is sounds like a fuel pressure or lazy fuel pump problem. Any problems with performance once car is started? Has anyone hooked up a scan tool upon start up to see what fuel pressures are. If the car is warm, does it start right up? You mention the car has to sit for a time for the no start condition to occur. This makes me think it could be a coolant temperature sensor malfunction or some other temperature related sensor. It is a very open ended question with too many possibilities for a no start condition. steviej

hard to say without knowing what the orginal trouble codes were. It could be that the failed O2 sensor allowed too much gas fumes into the CC and thus causesd that to crap out. Sounds like the chicken and the egg conundrum. steviej

I had both my rear calipers replaced by Lexus FOR FREE after a writing a letter to customer service. They original calipers were fine and pins replaced via the 2009 service campaign. Less than 2 years later both calipers supposedly remedied by the service campaign failed for the exact reason the serivce campaign was intended. Lexus is aware of the poor design of the lower caliper pin on the rear units. Simple resolve for me is to grease these pins well 2x a year when I swap my summer wheels for winter wheels and back. It is very easy to grease these pins. You have the same model as me, a 2006 which was the first year of this generation. It is expected to have some flaws. I do agree maybe more than other Lexus models. My 2002 ES was great and didn't have near as many quirks. But you will find that in any make, Acura included. Look back to the 2002 TL with close to a 33% failure rate on the triptronic transmissions. Every manufacturer has growing pains. steviej

have you tried www.tirerack.com? they have the Lexus sensors for pretty decent money. You will have to have the sensor mounted and then programmed into your ECU though so figure some money for that as well. Toyota dealerships tend to be less expensive in that task as well. steviej

the answer you seek lies in the reply to your post in a different thread: see below. You stated the reason yourself. It is because you diconnected the battery. Both the moonroof and power windows will have to be "normalized", in other words, they have relearn their respective programming. The instructions are clearly described in your owners manual and previously in this thread. Simply stated: Moonroof: push and hold the UP button unitl the moon roof tilts all the way up and then down a little automatically. Windows: 1. push down the power window switch for each window using the switch of each door so that the window goes halfway down. 2. then pull up the switch unitl the windows close and hold the switch for one second. steviej

request/kindly demand a meeting with the service manager, the general manager of the dealership and the regional Lexus customer service representative. Unfortunately that panel piece is about $900 online. Tell them that if they do not replace it, then you will move all your service business to another dealership and recommend to all your friends on and offline that they do so as well. The dealership stands to lose more revenue in lost service than they will by replacing one panel. Ask them to show you in print where their "bumper to bumper" warranty states that this piece is not covered. If you have a friend who is a lawyer, bring him to the meeting. Threaten small claims court. This will mean that someone from the dealership will have to show up on the court date, again a loss of revenue for the dealership. People's time is money and if the people are not at the dealership, then they are being paid to be elsewhere (ie. court). You follow me. It's worth a try to use minimal scare tactics. steviej

The button is red, the TRD and oval will light up green when you step on the brake. you can get it for $229 here $229, really??? :chairshot: steviej

Really. The plugs in there are iridium and these last a long time. I was skeptical at first on my 2002 ES and changed them at 60K (recommendation was 90k). I could have waited, the plugs were pristine. On my 2006 GS300 AWD, the recommendation is 100-120k. Again, on a Saturday afternoon with 90k on the clock, I had nothing to do so I replaced them. Once again they were pristine. As for the coil packs, I wouldn't replace them unless any unless it was giving you problems or is throwing a misfire code. And if that be the case I would start with the problem pack and replace one at a time. The buggers are quite expensive to replace as a precaution. steviej

sorry shiga, Lexus Limited Warranties are 4 years/50,000 miles.

Go for it. My winter tires (225/50-17) are mounted on the stock 17" wheels and my three season tires (245/40-18) are mounted on Lexus G-Spyder 18" wheels. There are plenty of options for 18" wheels out there, pick something that really pops (doesn't have to be Lexus brand. The only thing I noticed is the 18" tires rubbed a tiny little bit on the back wall of the wheel well when I cut the steering wheel all the way when making a left turn. This stopped after about 15,000 miles on the tires. steviej

I think it is the Trim Bezel for GS w/washer. Try here steviej

Billy, is your RX400h out of warranty? That part should be covered if you are still under. steviej

nope. If the wheels mounted on the car do not have TPMS sensors, thent he little idiot light will stay on. Two solutions: 1. get a second set of sensors and mount them in the new wheels, 2. put a little piece of black electrical tape over the idiot light. steviej
