2017 Lexus RX350 Engine Problems

“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.”

“In order to start the car, the brake must be pressed. However, if the car sits without use for several days, the brake pedal cannot be pressed down and the car will not start. A warning light indicates that brake power is low, stop in a safe place . Attached is a picture of the warning light. The car can generally be subsequently started by either waiting several minutes or exerting a lot of pressure on the brake pedal, and the warning light disappears. I've had many conversations with Lexus service and Lexus corporate office. …”

“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 !!”

“The contact owns a 2017 Lexus RX350. While the vehicle was parked, the start button was depressed, but the vehicle did not start until after the fourth attempt. The contact stated that the failure occurred approximately three other times. The contact also mentioned that the failure occurred only after the vehicle had not been driven for two or more days. In addition, the 'contact your dealer soon' message appeared on the message center. The vehicle was taken to the dealer (Lexus of birmingham, 1001 tom williams way, irondale, alabama 35210), but the failures could not be duplicated. …”
