Notes: Kiplinger's named it one of the greatest cars of the 21st century, we wouldn't go that far but for the price it's a nice ride.

RX 350

  • 43,000 miles


On November 3, 2015, Lexus RX350 (2011) came to a complete stop at a parking lot. When the gear was about to be put in to parking, the vehicle suddenly accelerated itself and moved approximately 40 ft forward. The car sprang out going over a cement parking block, iron fence that was dividing one building's parking lot to another, and fell about 5 ft below since the parking lot was in higher level than other building's parking lot. The vehicle kept moving even after falling from the higher ground and came to a stop after hitting a tree.

I was driving South on Georgia 400 merging onto 85 South when I saw cars stopped in front of me. I immediately applied me brakes - to no avail. My car kept going. I ran into the back of the car in front of me creating a four car wreck. I later learned from a market valuation report that: Service brakes, hydraulic Toyota is recalling certain model year 2011 Lexus RX350 passenger cars manufactured from August 30, 2010, through May 18, 2011, and equipped with vehicle dynamics integrated management (vdim). The calibration for the hydraulic control valves is incorrect. Due to this condition, there is a possibility that the right front wheel may not be controlled properly during ABS (antilock brake system) or vsc (vehicle stability control) actuation. This could result in increased stopping distances and/or a failure to adequately correct a vehicle slide, which could increase the risk of a vehicle crash. Dealers will replace the brake actuator with a new one, free of charge. The safety recall is expected to begin during August 2011. Owners may contact Toyota at 1-800-331-4331. Owners may contact Toyota at 1-800-331-4331. I was unaware of the recall, I never received notification. I took my car in for every scheduled maintenance. To the best of my knowledge, at this time, I was the only person injured in the crash. It appears that the problem was not corrected in my car; thus, I am filing a complaint.

Turned into parking space. Car began accelerating on its own. I applied the brakes continuously, threw the car into park to no avail. The car jolted forward, crashing into the storefront, breaking glass windows. The (approx) 2 feet of block wall stopped the car. The vehicle was not in my control in spite of all effort to bring the car to a stop. Had someone been walking on the sidewalk in front of the store (salon), I would have been powerless to keep from injuring or killing them. This was not driver error. I was fully "in the moment, " and aware of what was happening.

I was stopped at a red light. The car felt like it jumped / accelerated from nowhere, and I collided with the vehicle in front of me in a rear-end collision. Damaged caused to my entire front end and the other vehicles back end. Impact speed is unknown but it felt like 5-10mph and definitely not a roll-hit or a bump of a hit. I was stopped and then the vehicle just accelerated into the car ahead of me.

I experienced a sudden unintended acceleration (sua) in the parking lot of my apartment on March 3rd, 2012. It was a sunny day, and the road condition was good. My wife was driving Lexus rx 350 2011 model (mileage: 2124miles). My daughter and I were sitting on the back seats. She was slowing down the vehicle for parking and about to finalize the parking by going forward by about 3 feet. At that time, the vehicle abruptly accelerated with the sound of revving up the engine. The car ran over a parking block and went on curb stones. By help of the brake override system equipped after the recent Toyota's recalls, she could stop the vehicle quickly because her foot was already on the brake pedal. We all were surprised at this rare situation, but fortunately there were no accidents or injuries. We reported this experience to a close Lexus dealership. Two Lexus engineers inspected the vehicle, including 10-mile test driving. However, they could not find any mechanical problems. They could not re-enact the same situation, neither. At this inspection, they did not check out the event data recorder, as well as any electronic systems like etcs. According to the inspection result, Lexus directed me to keep driving this vehicle with my own risk. This is not related to the floor mat interference problem that led to the massive recall in 2009. So, I think the current Lexus users, as well as potential consumers, should be aware of the possibility that they can experience the similar unintended acceleration while driving or parking.
