Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

RX 330

  • 72,000 miles


I was turning into a parking space at work and my 2004 Lexus RX330 suddenly made a revving noise and accelerated into a tree in the median and then smashed head on into the car in the opposite space. The BMW that my car hit was completely totaled. My forward momentum was stopped by the BMW because my car climbed on the tree and ended up on top of the BMW. I was not on the phone and had no alcohol or drugs in my system and there was no passenger in the car to distract me. I am a 58 year old healthy woman who has been driving for 42 years. I took the car into my Lexus dealer and they checked the computer and claimed there were no defects. They told me I had probably stepped on the gas instead of the brake or the floor mat had gotten stuck on top of the accelerator pedal. I checked the pedal (as did a co-worker) right after the accident and the mat was not on or near the pedal. In addition, I do not believe I hit the gas instead of the brake as the parking spot had an uphill grade and I most likely was not yet ready to brake when the acceleration occurred. The weather was clear and sunny. My brother, who is an airline Pilot, suggested that it could have been the drive-by-wire electronics malfunctioning but the Lexus dealer assured me that could not possibly have been the case. Now, hearing about all of the other acceleration problems I believe my complaint should be added to the list of Lexus/Toyota unexplained unintended acceleration problems. If someone had been in front of me or in the car I hit they would have been badly injured or killed. I have pictures of the damage if you would like to seem them.

Ongoing intermittent sudden surges when I press lightly on the accelerator. The car will suddenly speed up much faster than the press on the accelerator pedal would warrant. Does not happen all the time. Have complained to the dealer each time since the vehicle was brought in for service, at least 5 times in the 1st 3-4 years. Each time, I was told they could find nothing, and that I just probably was not used to the car.

2 to 3 years prior to this accident I was coming to a stop light and the brakes did not work, but only for a few seconds. I reported this to my husband and he took it to several mechanics but did not find anything wrong with the vehicle, my husband has owned a auto parts store for 40 years and knows a few qualified mechanics. 3 people were on a freeway about 1/4 mile from off ramp doing about 65 mph, we started to move over to the slower lane as we got to the slower lane I stepped on the brakes to slow down for the off ramp when I felt the brakes were not working, I pumped the brakes several times to make sure I was stepping on the brakes but instead of slowing down the vehicle kept accelerating. I depressed the brake pedal as hard as I could and hung on for dear life upon entering the off ramp I struck another vehicle and flipped the car several times. I ended up with a cracked sternum, the passenger broke 3 or 4 of her vertebra, and passenger in the rear seat was fatal. Updated 03/10/10 updated IVOQ 09/28/10 update 9/19/2011

Rapid acceleration as I released the gas pedal as I parked my car - took out a 6 foot bush. I was interviewed on 10news san diego concerning this incident I took the auto to my Lexus dealer/a diagnostic and a test drive were done and everything checked out negative. The dealer told me they could not do anything to help me since the diagnostics were negative.

No failure, just apparent stickiness in accelerator. Occasionally, while pulling out from signals, pedal feels as if it is sticking, then will pop loose and car lurches forward.

I own a rx 330 Lexus and it has a problem with the accelerator. Sometimes it gets stuck at about 3 rpms and it wont come down from there until something lets go of it and then it jerks even though I would be going at a low speed such 25mph. The accelerator feels rigid and no matter how much you push on it the speed doesn't increase until it jerks and lets go. Other times it tends to go faster even though I am not pressing on it, when I brake it doesn't want to stop until I slam on the brakes hard. I can feel that it is like something is stuck and the car does what it wants until it is let go which is when it jerks. I have not had a crash yet, but I am concerned about it.

1994 Lexus RX330 hesitates while depressing the accelerator. The vehicle has been taken to the dealer several times to alleviate the problem but they claimed that the vehicle was operating within normal specifications. The vehicle has also been plagued by other malfunctions to include squeaks, rattles, multiple malfunctions of the sunroof electronics, broken seats and liftgate alignment problems. Updated 08/14/06.

RX 330 6-cyl

  • Automatic transmission
  • 5,000 miles
I am leasing a 2004 Lexus rx 330 fwd with about 20,000 miles on it. When I try to apply the throttle after slowing down there is a severe hesitation, usually followed by a sudden surge in power. At times there is an additional hesitation while the transmission is deciding what gear it should be in. This is especially noticeable while making a turn at an intersection, and especially dangerous if there are pedestrians in the intersection. I have had it to the leasing dealer (longo Lexus) and they reprogrammed the transmission, which provided a temporary and partial fix. After a few weeks, aparently the transmission reprogrammed itself and the problem returned. I took the car to a second dealer and he said that they had many similar complaints about that driveline, but there was no factory fix. I called Lexus customer service and they said the same. This problem began shortly after I got the car in April 2003 and still exists. If Lexus truly wanted to fix this problem, it would have already been done. They need a push.

I have had two problems. One being yesterday I came out to my car in the parking lot started up my car and there were no brakes. Had to put car in park to stop car. The brakes were rock hard. They said it was the booster that had to be repaired. The second problem is I had almost 2 accidents when trying to accelerate from a stop sign. I hit the gas and the car doesn't go it lags and then goes. This hesitation is very very serious and has me very worried about driving with kids. I bought this car for the safety features and now I'm scared to drive it. What if my brakes failed on the highway I was on" what if my car lags in front of a truck"

Re: supplement to consumer complaint #10091268 Lexus rx 330 transmission/throttle problems. Automatic transmission hestiates, hunts, shifts inconsistently, hangs in between gears, delayes, etc. The throttle delays at the first application of gas and the rate of acceleration surges up and down unevenly. Dealer could not find a problem.
