i have had the same problem the quick and safe also cheap fix is just get a alarm system installed and it will also trigger both alarms once the door lock mode is onthen you will have double coverage on your security systemalso have keyless entry because a new brain will run about $500.00 plus other charges a new alarm can go cheap as $130.00 installed (viper system) also your insurance company may give you a better rate mine did (USAA) good luck

well unfortunately we all have the same problem i have a 1993 lexus ls400 2nd owner i am, i brought it with only 135k had the same problem with the climate control and the instrument cluster lighting took it to the lexus dealer in Alexandria Va they told me to call lexus to see about a recall because of the cost to repair it was great and Lexus America came back with my car was too old to do a recall or give any assistance on getting this problem fixed also my car was only serviced at the lexus dealer once since it was purchased from lexus by the first owner, mind you the car is in immaculate condition other than the instrument cluster and climate control it was certified by the lexus dealer in alexandria va 2 days after i purchased but lexus america would not budge at all on any assistance i am a owner of 2 other lexus cars and was pretty up set because these issues are from the manufacture defect and the consumer have to pay it is not fair we already pay a lot for the luxury automobiles and getting them broken from the assembaly lines. i think we as lexus owners we need to flood lexus of america email system until they give us satisfaction we have nothing to lose

I have a '97 Lexus ES300 (105K miles) and got a check engine light 2 days ago. I got it checked and it comes up with a P0420 code. The code description says "Catalyst System Efficiency Below Threshold (Bank 1)".

As I understand, it could be due to a defective catalytic converter, damaged O2 ensors, contamination of converter due to incorrect sealant, fuel, or fuel additive.

I had 2 repairs/services done on my car in the past 6 weeks:

1) I had replaced the flex pipe and the catalytic converter about 6 weeks ago. The flex pipe was leaking and the exhaust was making a lot of noise. My mechanic advised that I also replace the cat. I got the aftermarket (generic) flex pipe and cat.

2) I had a service done a week ago. I got the transmission liquid flushed, radiator coolant flushed and fuel injection service done.

My guess is I am getting this code due to something gone wrong in either of the above 2 repairs/services. The most obvious cause would seem to be the first one, but I don't know if I can rule out the second one as that was the most recent one ( a week ago).

I would appreciate if someone could help me with this. Could the second service cause P0420 to be set? Or is it possible that I just got a bad converter in repair 1? If yes, then would it take upto 6 weeks for the code to be set?

Any additional advice or suggestions would be appreciated.

Thanks,
