Lexus RX 350 Slow Gas Pedal
One reason the gas pedal may be slow is to prevent unintended acceleration. Another reason may be to save fuel, as a slower pedal would require less gas to accelerate. Additionally, a slow pedal could be meant to provide a more comfortable ride for passengers. Manufacturers have set a slow response on purpose in order to follow both State and Federal requirements. There are a couple of simple ways to adjust this setting by either a Tune or Throttle Response Controller.
The throttle response controller is the easiest and least expensive way to test changing this setting. A good throttle response controller will have a long warranty which ensures high-quality parts are used. You also want good customer service, easy-to-use, and connections to your smartphone.
For these reasons, we are recommending ShiftPower Throttle Response Controller. ShiftPower has a 5-star rating from car enthusiasts who demand the best performance from their cars. Click to learn more about ShiftPower >
Why are manufacturers slowing down the gas pedal?
Simply, the manufacturer is slowing down the amps from your pedal to the engine throttle computer module. But a throttle response controller will solve this by amplifying the electrical amps.
If you're concerned that your gas pedal is too slow, take it to a Lexus dealer and have them check it out. They may need to adjust or replace the accelerator pedal.
In the meantime, you can try a throttle response controller. This will amplify the electrical amps from your pedal to the engine throttle computer module, making the gas pedal respond more quickly.
Lexus RX350 common problems
There are a few common problems that owners of the Lexus RX 350 have reported.
There have been a few reports of issues with the gas pedal response on the Lexus RX 350. Some owners have complained that the pedal is unresponsive or "slow" to the touch. This can obviously be a major safety issue, as it can prevent the driver from accelerating when needed.
There are a few potential causes for this problem. One is that the gas pedal itself may be worn out or damaged. Another possibility is that the fuel pump is not providing enough pressure to the injectors, which can cause a "hesitation" when the pedal is pressed.
If you are experiencing this issue, it is important to take your vehicle to a qualified mechanic or Lexus dealership for diagnosis and repair.

One of the most common issues that can cause a Lexus RX350 to have a slow brake pedal is air in the brake line. If there is air in the brake line, it will prevent the brake fluid from flowing properly and result in a spongy or slow brake pedal. The best way to bleed the brakes is to use a professional brake bleeding kit.
Another common issue is a leaking brake caliper. A leaking brake caliper can cause the brake fluid to leak out, which will result in a slow or spongy brake pedal. If you suspect that your brake caliper is leaking, it is important to have it replaced as soon as possible.
Worn brake pads are another common issue. If the brake pads are worn, they will not be able to generate enough friction to stop the vehicle properly. As a result, the brake pedal will feel slow or spongy. If you suspect that your brake pads are worn, it is important to have them replaced as soon as possible.

Failure mileage issues
The consumer states while driving on the highway and applying pressure to the gas pedal vehicle failed to accelerate and almost caused an accident, consumer had to pull over to the side of the road. Upon inspection by a mechanic, it was determined that there was something wrong with the throttle body.
The consumer was told that the part would have to be ordered. The vehicle was towed to the dealer for repairs. The contact also stated that the failure recurred. The approximate failure mileage was 168,000. Updated 04/07/11 the consumer stated that the pedal would get hard to press and the engine would rev, but the vehicle would not move. The consumer was told that this was an issue with the transmission.
The contact owns a 2007 Lexus RX350. The contact stated that while depressing the accelerator pedal, the vehicle failed to accelerate. The contact also stated that the failure recurred on numerous occasions. The vehicle was not diagnosed or repaired.
Accelerator Pedal Improved
The best way to easily improve your accelerator pedal is by installing a throttle response controller. This will help you get a better throttle response from your engine by allowing you to better control the amount of air that enters the engine. This is especially helpful if you live in an area with a lot of stop-and-go traffic.
Normal mode default settings
The default settings for the throttle response controller are:
Low mode - 50%
Medium mode - 75%
High mode - 100%
These settings can be changed by the user to better suit their driving style.
Additional Reported Problems include:
- Air bags failed to deploy during a crash.
- Sudden unintended acceleration has been reported by some drivers. The failure occurred while reversing from a parking space.
- The vehicle accelerated on its own while the driver was braking.
- The emergency brake assist failed to work.
- The steering wheel may become very hard to turn. This can happen suddenly and without warning.
- Sudden acceleration has also been reported. The vehicle accelerated on its own while the driver was braking.
- In some cases, the gas pedal has become stuck and the car accelerates on its own.
- The car drives fine when you press the gas pedal lightly, but when you press it down hard, the RPMs go up but the car doesn't move any faster.
- One complaint is that there is a big dead spot in the pedal range. This can make it difficult to start from a stop and makes it hard to modulate speed when driving.
- The car jerks or surges when accelerating from a stop. The engine hesitates or stumbles when trying to accelerate.
These are just some of the common problems that have been reported by owners of the Lexus RX 350. If you are experiencing any of these issues, you should take your car to a Lexus dealer and have it checked out.
Frequently Asked Questions ShiftPower Throttle Response Controller
What is a throttle response controller?
A throttle response controller is a device that is used to improve the throttle response of a vehicle. It does this by increasing the amount of air that is allowed into the engine.
The increased airflow that a throttle response controller provides can lead to a number of benefits. First, it can improve the performance of the engine by increasing the power and torque that it can produce. Additionally, it can improve the fuel economy of the vehicle by allowing the engine to run more efficiently. And finally, it can reduce emissions by allowing the engine to burn fuel more completely.
If you are looking for a way to improve the performance of your vehicle, then a throttle response controller may be a good option for you. However, it is important to keep in mind that these devices are not magic bullets and they will not make your car into a racecar. Instead, they are designed to provide a modest increase in performance that can be enjoyed by all drivers.
How does a throttle controller work?
The ShiftPower Throttle Response Controller is a highly patented and unique product that uses a vehicle’s existing computer system to control the amount of power available to the engine. It is a "plug-and-play" device that requires no special tools or extra wiring; it is completely reversible and leaves no trace that it was ever installed.
When you press the gas pedal, the ShiftPower controller intercepts the signal and modifies it before it reaches the engine control unit (ECU). This tells the ECU to deliver more or less power, depending on how the controller is set. The result is a significant improvement in throttle response, and you can adjust the amount of power delivery to match your driving style.
Who should use a throttle controller?
Any driver of a Lexus RX 350 who experiences a slow gas pedal should use this throttle controller.
This throttle fix works by restoring the proper pressure to your RX 350's gas pedal, allowing you to enjoy the normal operation of your vehicle.
What are the benefits of using a throttle controller?
The benefits of using the ShiftPower Throttle Response Controller are to help eliminate throttle lag for better acceleration or reduce throttle sensitivity for more control. This is especially useful for towing and off-road driving.
Best of all, the app shows what's happening with your vehicle's throttle in real time, eliminating acceleration delay with various modes.
