Loss of power brake assist. The Lexus dealer diagnosed a failed vacuum pump. This is common with the 2016/2017 RX 350's. Lexus has admitted a manufacturing problem with the pumps and has a service bulletin (L-SB-0010-18) and a safety recall on the 2017's (JLD J2D). The recall should be extended to the 2016's. There are tons of people posting on the internet about failed vacuum pumps and resultant safety issues.

We took a car for lease from Lexus. The first week, we realized the brakes weren't working well. We took the car to the shop and they said nothing was wrong. Then, a couple of months later it happened again and they said the same thing. Last week, after 2 years, I was driving and so was my daughter ( two different times ) and we couldn't break the car. The car drove right past the intersection on a red light. Thank god there was no pedestrians or vehicles at that second. We brought it to alexus and they tested the brakes and saw a problem with the brakes. The pressure was low and the metal was scraping. They asked for a large sum and said we never complained before.

First problem with electrical was when the navigation screen went completely blank while driving during broad daylight. Don't know the date of this incident. Thought it was a reboot by enform. Thought nothing about it. On 12/21/2017, check electric brake warning light came on when I started my car in the morning after it had been sitting all night. Took into the dealer. Dealer could not find any problem with it or any error codes indicating any problem. They reset the error light. On 4/23/2018, I stopped for a stop sign at about 12:30 pm, nothing happened when I tried to accelerate at which point I noticed I had no lights on anywhere on my car. It was dead. I was stuck in the middle of the road and was unable start it after a couple of tries. Called for emergency service, let Lexus dealer know my car was going to be towed to them, and sat for about 15 minutes when a gentleman came along before emergency service rep got there. He was able to start the vehicle. Took to dealer and was told after 4 days that they could not recreate the problem. Am now driving it, but afraid something else may happen.

There was a line of cars at the red light, I continued applying the brakes, the car would not stop and was picking up speed. I pulled to the left to avoid all the cars. Car still would not stop inspite of pressing my foot hard on the brake. The car continued moving went across a large street, still turning the car to the left to avoid other cars. The car went on to a gas station lot. I continued turning to avoid the gas pumps, still my foot on the brake. The car kept going and stopped when it hit a pole on the gas station lot.

I will give you a brief description as to what occurred. I entered our garage for the purpose of backing the Lexus out of the garage so we could load newly purchased patio furniture into the garage. I entered the Lexus, applied the brake peddle to start the automobile. Once the auto was started, keeping my foot on the brake to allow my shifting, I move the shift lever from park to reverse and to my surprise, the car began moving with never removing my foot from the brake. It is a very tight squeeze backing out of our garage so when the car started moving, I pressed more firmly on the brake to slow the progress and there was no response. I pressed on the brake harder and when it kept continuing to not respond, I tried to locate the emergency braking system by pushing with my left foot on the floor trying to engage it. The whole incident lasted only a couple of seconds causing the collision to occur. This was reported to hartford insurance company auto claim # PA0016731644 whose ultimate conclusion was as follows: "upon further investigation we determined....the Toyota motor company to be the responsible party." My last communication with Toyota motor North America was with carlos garcia in the legal claims department dated February 10th, 2017, copy attached also attached is my correspondence of May 11, 2016 the bottom line is Toyota has not conducted an in-depth investigation of a significant failure in the design/manufacture of their automobile. They are totally relying on hearsay evidence which is third hand and false, hoping this will all go away. I made my automobile available to them as well as myself and others who witnessed the event. This could have been a innocent child that was damaged, rather than another vehicle. I have significant additional information available for you, if requested. Thank you for your concern.
