July 11th 2017 at around 220pm pst, the Lexus RX350 2012, experience a very dangerous failure. Earlier that week I noticed issue with the battery, where it would take one or more pushes to the start button for the car to turn on. But on this date, I had just parked the car on a road with an slight incline, I did not enable the emergency break the car was turned off and the keys with me. I had dropped off a friend and helped her take a few things inside the house. After returning to the car, I tried multiple attempts to turn on the car (3 or 4) and on the last attempt the car roll down the hill instead of turning on. I was un-able to apply the breaks and in a state of shock did not apply the emergency break. The car roll across a road, down a bank and came inches to hitting a home. After the car was towed up the bank it was found the car was in good shape but the battery was dead. I was in a state of shock and my entire body tensed and I was suffering from a severe headache. We called in the California highway patrol 1722 East main street el cal jon 92021 date: 7/11/17 - 14:40 ncic number: 9680 officer id number 21588 there after we called contacted Lexus to determine if all recall service had been applied, which they answered your car does not apply to an earlier recall. Was referring to the following recall. Based on the name seem quite applicable February 12, 2014 NHTSA campaign number: 14V054000 brake actuator assembly may disable ESC and ABS I requested for a independent evaluation, but they told me (Lexus)would not pay for it if their were issues and I must take it to a Lexus service department. I complied and we took the car (it was towed over). They held the car for five days and concluded the car had a bad battery. They state the car was in neutral when it was parked. We are fearful of another accident result in greater damage and harm

The car, a 2012 Lexus RX350, was purchased new from a California Lexus dealer on January 30, 2012. The problem, which manifests every two or three days, is a delay of several seconds between pressing the accelerator pedal and actual acceleration of the vehicle. When acceleration eventually occurs, it does so with a surge or jolt. The problem has occurred in a variety of circumstances. Several times I have been unable to accelerate safely from a freeway on-ramp into faster-moving freeway traffic. On at least two other occasions the vehicle has failed to accelerate as I drove up a hill. Most recently, as I began a left turn from a stopped position, the delay in acceleration nearly resulted in my being broadsided. I have taken the vehicle twice to an authorized Lexus dealer. On both occasions I was advised that because the technician was unable to reproduce the problem during a short drive, there was nothing they could do. I raised with the technician the fact that there were numerous complaints online about the very same problem. He said that the issue, which apparently relates to the powertrain, had been addressed with respect to earlier Lexus models but had been "fixed" for subsequent models through redesign of the powertrain.

I bought the new car from a Lexus dealer in NJ on Saturday 12/03/2011. Right after the car was delivered to me and as I drove the car out of the dealership, I noticed that RPM surged whenever gear upshifted specially in 15-40 mph range. My wife also noticed the same issue. We brought the car to the dealer on following Friday, 12/9/2011, and explained the problem. When I brought the car back to the dealer for inspection, it had ~340 miles on it. One mechanic at the dealer road tested the car with me and noticed the same issue. We left the car at the dealer on that day. On following Monday afternoon (12/12/2011), the dealer called and said the transmission is failed and has to be replaced. We have serious concerns about the quality of the car and resulting safety issue: Power train is the main component of a car that has direct implication on a car's safety. This car was a defect even before it was delivered to me. I also have serious concerns about the rigor of Lexus new car inspection process before customer delivery. We are concerned that this kind of power train issue can lead to a more serious sudden acceleration problem that causes disastrous accidents. With this defected car, we might have gotten into an accident right after delivery due to power train failure.
