Was your Sirius radio dealer installed? What did it cost? Do you have an RX400h? My dealer is telling me that they cannot install in the 2006 RX400h and that I should go aftermarket.

We've had our 2006 RX400h for six months now and the wife would like satellite radio. Searching here and reviewing the Lexus web site, it seems that Lexus dealers can install either XM or Sirius upgrades that fully integrate with the car's radio display (we have Mark Levinson option). Any information from the experts here on prices and your experience with dealer installed satellie radio options -- either XM or Sirius -- are much appreciated. Jim

My wife felt the same way when our RX400h was in the shop and she got an RX330 loaner for a week. She was SO GLAD that we bought that RX400h!

We've actually been pleasantly surprised at how good the voice quality is with the Bluetooth hands-free in our Lexus RX400h using our Verizon Nokia 6256i phone.

Why not post the step-by-step instructions here? This questions comes up often, and Verizon's Bluetooth phones are very challenging.

Be careful about using cheap gas in your Hybrid. We had problems with our brand new RX400h that was supposedly caused by bad gas .... http://us.lexusownersclub.com/forums/index...showtopic=27584 Bottom line .... frequent use of quality fuel cleaner additive (RedLine or Techron) is recommened.

On my Verizon Nokia 6256i you transfer contacts one-at-a-time as "Business Card" contacts. Not sure if it's the same with the Motorola.

Update 2/18/06: Got our RX400h back today and it seems to be all better. They replaced all 6 fuel injectors, pulled and cleaned the fuel tank, and replaced the fuel filter. They still think it was a bad batch of gas. Our service advisor said that the RX engines have especially sensitive fuel injectors. He suggested adding a bottle of Redline SI1 or Techron fuel cleaner additive every 3 months or so to help keep them clean. Here are the details from the work order of what they diagnosed and performed .... Check engine light on, flashing then solid. Find codes P0300, P0304 & P0305. Misfires on cylinders. Clear codes and inspect data while engine under load. Noted misfires in excess of 50% at #5 cylinder only. Find misfire not always current. Find fuel trims well above normal. Also above normal for code stored data for "P0304". Contacted "TAS" for concern. Find no pending codes other than noted above. Perform misfire isolation diagnoses. Swapped ignition coils and spark plugs with #5 and #6 cylinders. Recheck for misfire. Find misfire still within #5 cylinder. Inspect fuel quality = unknown. Misfire caused from lean burn at #5 injector. Also pending codes P0300, P0302 & P0305. Perform A/F control active test. Set A/F to "+25%". Noted large improvement with no misfire felt. Remove & renew all fuel injectors. Remove fuel tank and renew filter/suction sock. Reinstall tank and check for leaks. Extensive drive test. No misfire noted. Recheck engine control and values are well within normal ranges. Clear codes and test drive second day with cold start. All good.

Update 2/13/06: Well, the Service Advisor called today and they're convinced the problem was indeed bad gas. His theory is that "suspended polymers" clogged the fuel injectors, although there was some disagreement with the "experts" in California who initially thought it was an electrical problem. So now they've ordered new fuel injectors and filters and will clean the tank and fuel pump. Hopefully we'll have our RX400h back by Friday this week. My Service Advisor also told me that the RX fuel injectors are especially sensitive to fuel contamination problems .... something about the "unique design" of the RX injectors. Obviously this is a bit worrisome, especially when we've only bought name brand premium fuel. How does one prevent it from happening again? I wonder if using an additive like RedLine SI-1 Fuel Treatment regularly would help?

I do remember that incident. One would hope that gas batch is long gone from the supply chain. I will certainly be asking that gas station about it if the Lexus tech truly thinks it was bad gas.

Latest update, Friday, Feb 10, Noon: Service advisor tells me that it was an "engine misfire" diagnostic trouble code. Additionally he told me that they are currently leaning in the direction of fuel contaminarion, which restricts the injectors and causes check engine light and driveability concerns. They will be checking further Monday (today is Friday). If it's fuel contamination it very well maybe necessary to replace the injectors. I would be surprised if it turns out to be fuel contamination because we only use name brand (76 Union) premium gas. I'll keep you all posted.

The service techs certainly acted like it was a first for them, too! I just hope we don't have "lemon" :(
