You are in the Lexus RX 300/330/350
What is this discussion about?
Lexus RX 300, SUV
#8559 of 9498 RX 300 Towing harness/converter
May 25, 2005 (8:58 pm)
My 2000 RX3000 lost tail light power when I plugged in my trailer. The tail lights are out on the trailer too but the brake and turn signals function normally. It was my understanding that there is a fuse near the converter that probably is bad. I checked and could not find the fuse? Finally I took the RX to my Lexus dealer. I was told that the converter was out an it would cost over $500 to replace it. I asked about the fuse without response and finally talked to a service manager. He said my model did not have a fuse. After further discussions we agreed on a much lower cost for the repair. Still they didn't have the part and had to order. Meanwhile I'm confined to daylight driving since the main tail lights are out. Does any one know of a work around for getting the rx tail lights to work without the converter ?
Not having an expensive component properly fused seems like a very incompetent action on Lexus's part.
#8560 of 9498 exhaust system noise and life expectancy
May 26, 2005 (2:35 am)
I have a 2000 rx300 with 155,000 miles. There is a noise from the exhaust system that sounds like a leak. Is this system stainless steel and should corrosion be a problem?

Almost all of the incandescent light on a Lexus have a failure monitoring system. This consists of a small low wattage resister in series with the positive voltage supply side of the circuit inside the ligh control module. If you add an addition current load of any great significance to any of these circuits it is highly likely the resistor will burn out.
#8562 of 9498 Exhaust Leak
May 26, 2005 (12:14 pm)
I have a '99 RX with 115,000 and have heard a louder noise from the exhaust system lately. I get my oil changed at the Toyota dealer and asked them to check on it. They said they couldn't find or hear an exhaust leak. Let me know what you find.
#8563 of 9498 Dirty Xmission Fluid
May 26, 2005 (1:54 pm)
Flushed fluid on a 2002 RX with 51K miles. Mostly highway. Very dirty, will start to do every 30K or less.

I have a 2001 FWD RX300 with Nav. I'm nearing 70k miles.
Has anyone encountered a fairly loud and intermittent chirping sound? Mine is coming from the front right wheel well - at least that's what it sounds like when I'm sitting in the car. It happens when the car is at a standstill as well as when it's moving. It seems to start when I start the car, and then mysteriously fades away.
I, too had problems with my roof rack paint chipping off; Lexus replaced it after I requested it a second time. And I had sludge problems which resulted in Lexus taking my engine apart for repair.
I'd appreciate hearing some thoughts about the chirping sound. Thanks!

Hi yes I have the same issue. I have similar model, no Nav. Similar mileage. Same sound, same instances, same situation. No idea though. Water pump? Mine seems to happen more when it is damp/rainy outside and mild temps. Goes away after some highway driving or continued driving.

Could it be that you have a noisy belt? I have an RX300 with 43000 miles. I noticed a ringing type sound when the RX is coasting (no gas pedal pressure) or when at a stoplight. It goes away when I push on the accelerator. I asked the mechanics to lube and clean the serpentine belt and the noise has gone away.
I wonder if this may be your problem.

My Mass Airflow Sensor went recently. It had been cleaned a few times previously by the dealer, but I guess it finally went. I have a 99 with ~80K miles. When I brought it in the vehicle ran very badly, the engine light had gone on and off once and the vehicle wouldn't accel. briskly. Luckily the part was covered by the extended warranty.

Any AWD RX330 owners out there encountered this ATF overtemp warning
and if so under what conditions?
