The transmission on this vehicle is bad! The dealer keeps saying it's normal in the learning phase, but there is no way all of this sputtering and hesitation is normal for any vehicle, let alone a luxury one. The tachometer jumps, jerks and sputters as well if you watch it. The pre-collision break system is also severely flawed. It has braked so hard that it screetched and no one was even around me!!!!! This clearly almost gave me a heart attack three times now. It has happened twice when slowly backing out of a parking spot, and one time while driving down the street at a normal rate of speed and no one was around me at all.

From the first week I purchased this new 2017 lexus rx350, I noticed that rapid acceleration is not possible. There is a momentary hesitation after deeply and rapidly depressing the accelerator. This is mostly noticed when aggressively pulling into a traffic lane say, from a side street or parking lot, or when attempting to pass another vehicle. When the accelerator is rapidly pressed to the floor, the RPM's nearly red-lines but the vehicle doesn't accelerate for nearly a second, which seems a dangerously long time when you're in traffic. This is not only aggravating, seeing I paid so much for what is advertised as and supposed to be a highly rated car but is dangerous this car can not accelerate as rapidly as it should. I made the dealer aware of the problem and he said it is a known issue with some of the cars and it is fixable but can't until it is approved by some government agency. The car is less than 6 months old with less than 6,000 miles and I feel it is not safe and don't want it anymore unless it can be fixed very soon.

At 1800 miles, vehicle started to hesitate when pressing on gas pedal. When accelerating from stop, vehicle is hesitating and studdering very badly. This is affecting accelerating and causing a severe safety issue while driving. While at highway speeds, vehicle constantly is lunging hesitating when trying to merge into traffic. This has almost caused 3 accidents as in stop and go traffic, when pressing on gas to accelerate, car is shuddering and not finding right gear. Do not feel safe in car. Feels like car is going to stall out !!

When accelerating hear a loud groaning noise and feel a hesitation in the gas accelerator pedal. Have brought to the dealer 3 times, as it seems to be getting worse. Dealer acknowledges their is an issue, but says will not fix because their is no recall. They said will notify us if/when lexus has a remedy. Apparently this is happening on 2016 & 2017 models. I am worried that my car is just going to lose power when accelerating as it seems to be getting worse and louder groaning noise. This happens first thing in the morning when the car is cold and accelerating between 0 to 20 MPH.
