Engine recalls for the 2005 Lexus RX330

Engine and engine cooling

11V539000420,326 vehicles affected

The problem
Toyota is recalling certain model year 2004 avalon vehicles; 2004 and 2005 camry, camry solara, highlander, and sienna vehicles, 2006 highlander hybrid; 2004 and 2005 lexus es330 and rx330; and 2006 lexus rx400h vehicles manufactured from june 1, 2004 through march 31, 2005, equipped with the 1mz-fe or 3mz-fe engine. The amount of adhesive agent applied between the outer ring and the torsional rubber damper (inner ring) in the crankshaft pulley may be inadequate. If the adhesive is insufficient, there is a possibility that the outer ring may become misaligned and it may not properly rotate with the inner ring, causing noise and/or illumination of the battery discharge indicator light.
The risk
In some cases, the belt for the power steering pump may become detached from the pulley which could result in a loss of power steering and a sudden increase in steering effort, increasing the risk of a crash.
The fix
Toyota will notify owners, and dealers will check the crankshaft pulley to identify whether it was produced by the u.S. Supplier. If so, the dealer will replace the pulley with a new one at no charge. The safety recall is expected to begin during early january 2012. Owners may contact toyota at 1-800-331-4331.

damage to the engine compartment, electrical wiring, and surrounding components. The vehicle became unsafe to drive, and the engine can no longer operate. This incident presents a serious safety hazard because the fire happened shortly after a repair that involved components near the engine and fuel system. Improper or unsafe repair work may cause similar fires for other consumers. This incident is already under active investigation by: • California Department of Insurance (CDI) - Complaint #[redacted]• California Bureau of Automotive Repair (DCA/BAR) - Case No: [redacted] I am reporting this to NHTSA because the fire and melted engine components indicate a dangerous defect tied to improper repair work, which may pose a risk to other drivers.

skid mark before crashing into the front of the business. The car has done this before especially when turning and applying a little gas, it will hesitate and then suddenly accelerate, but never continuing after applying the brake. We have discussed this previously with the lexus dealer and they say there is no problem with the vehicle and that computers that control the engine and transmission constantly adjust to the primary driver may create this issue, but it is not a problem as far as they are concerned....Updated 09/08/15*bf updated 12/3/15 *js

My air vents constantly emit a white powdery substance that collects on the dashboard and within the vents. I have complained to the dealership with concerns of what I am inhaling into my lungs and was told that the calcium coating is coming off of a tube or wire and the calcium then gets blown out of the air vents into the passenger compartment. They also stated that the substance is not harmful if inhaled but I am not sure I believe that. The repair cost would be thousands of dollars because they have to...

My vehicle is a 2005 lexus rx 330. I purchased it certified pre-owned in 2007. I was coming off the highway and stopped at a light. As I proceeded to take a left hand turn the car started making a loud noise. It was jumping and shifting from side to side. Luckily I was able to control it and pull into a nearby gas station. I couldn't drive it and had it towed to the nearest lexus service center. I was then told that the transfer case on the front differential went. They opened up the case box and metal...

shavings fell out! I guess there was no transfer case fluid! Shouldn't a maintenance required light pop on or a warning? If I had continued on the highway rather than get off the exit, it would have ended badly! The back end of the car completely locked on me. I don't understand why there was no warning light. How am I supposed to know that the transfer case is running out of fluid? The service department said this is not normal. They want to charge me $2700 for the part and $1500 for labor! I ended up having the car towed back to my house until I can figure out what to do. I have a serious issue with the fact that there was no warning and had I been traveling on the highway at a higher rate of speed, I could have flipped the car and ended up in the hospital or dead. I would really like for lexus/toyota to do something about this! *Tr

My 2005 lexus rx 330 with only 39459 mileage was told the water pump is leaks, when I replaced the battery at independent shop. When for a recall (engine crankshaft pulley) done by dealer that couple month ago on mileage 39152, dealer also performed multi point inspection did not spot any water pump leaks. However, I brought car back to dealer to diagnostic, inspected states that for possible coolant leaks - water pump timing belt package cost $1,995.00 For replacement. That is outrageous, I could not believe...

that the water pump is failing at the car only has under 40k miles. This is a very serious issue for safety as an engine with failed water pump might be cause a very serious damages and injury when driving. In this case hereby, I'm sending this compliant to nhtsa, I hope odi office would start to investigation for this issue. Lexus should make recall for this low quality parts instead of put other peoples life in dangers when driving. To emphasize that I have found out on your website there are same complaints for failed water pump as well. And I believe that there are lots of car owner have same problems just were not aware of where they could make complaints. Thank you so much for your attention in this matter. *Js

Took my 2005 rx330 in for a recall (crankshaft pulley). I was told the water pump was leaking and should be taken care of along with the timing belt. I was told I would save a couple hundred dollars in labor because of the recall if I had it taken care of right now at a cost of $876.96. Ouch! Only 50k miles! At least it didn't happen while I was driving, but come on 50k miles. I hope this isn't an issue among other 05 rx330 owners. Might have the tune of recall.

My lexus rx330 broke down at the middle of a busy road only at 65k miles. The water pump had a leak, and as a result, there was no coolant and the engine was heating up to a level where I could have fire in the engine. I was not able to drive the vehicle and it had to be towed. Later I paid $1100+ to replace the water pump and timing belt. I contacted lexus hq regarding serious quality issues with their vehicle as the water pump and timing belt should last up to 90k miles. Lexus refused to help or even...

acknowledge that this is an issue. I am reaching out to nhtsa and requesting an investigation of this quality problem with lexus vehicle and key engine parts like water pump. Toyota/lexus has been using low quality parts to increase profit margin and as a result, the engine is failing at only 65k miles. This is a serious issue for safety as an engine with a failed water pump can heat up and cause fire and fail at the middle of busy intersection or on the highway. Will appreciate if you please look into this issue asap and require lexus to do a recall on their water pump for all 2005 rx 330s. *Tr

I did not touch the gas petal, the mats are rubber and were not a problem. The vehicle just suddenly accelerated. The air bags did not deploy and I shut the engine off as soon as I could...

but given the fact that the total travel length was around 30 feet this was not possible. This is a know problem with toyota!! We love our car but we are now afraid of it. My insurance rates will be going up because of a factory defect and all I have seen are excuses in regards to this problem. *Tr

I purchased a used 2005 rx 330 3 weeks ago (i also purchased what I was told was an extended road hazard coverage). I decided to take my daughter and granddaughter to disney world (a 200 mile trip this weekend. Just as we arrived in orlando my daughter said that she heard a pop (it was not loud as I did not even notice it)and we noticed steam coming from the engine. The suv was towed into lexus of orlando and although on vacation I was left without a car and still have none. To make matters worse, I was called by...

lexus of orlando and told that I would have to pay $1000 to have my car repaired because allegedly the issue is damage to the a/c compressor caused by a 'road hazard'. The 'road hazard' was a piece of reflector used to separate the lanes. Lexus has refused ot repair under warranty even though I was sold a 3 month, 3,000 mile everything warranty (in addition to the lexus certified warranty) and the everything warranty has no exclusions was to cover any damage. I spoke to a mechanic who told me that for a road reflector to cause this type of damage, there must be a design flaw in the protections afforded by the grill or otherwise to the a/c radiator area. In researching this issue I noted that others have file identical complaints, including on this site. *Jb
