The Lexus RX 350 is well-known for its comfort, luxury, and reliability. Many owners appreciate its power liftgate, which makes loading and unloading cargo easy. However, some drivers have faced power liftgate problems that can cause frustration and inconvenience. If you own a Lexus RX 350 or are considering buying one, understanding these issues and knowing how to fix them can save you time and money.
What Is The Lexus Rx 350 Power Liftgate?
The power liftgate is an automatic rear door that opens and closes at the push of a button. It uses electric motors, sensors, and switches to move smoothly. You can control it using the key fob, a button inside the car, or a button on the liftgate itself. This feature is popular because it helps when your hands are full or during bad weather.
Common Lexus Rx 350 Power Liftgate Problems
Like any electronic part, the power liftgate can sometimes fail. Here are the most common problems reported by RX 350 owners:
1. Liftgate Does Not Open Or Close
This is the most frequent issue. The liftgate may not respond to the button or key fob. Sometimes, it may get stuck halfway and stop moving.
2. Slow Or Jerky Movement
Instead of moving smoothly, the liftgate may move slowly or in a jerky way. This can be a sign of worn-out struts or a weak motor.
3. Strange Noises
Unusual sounds like clicking, grinding, or buzzing can come from the liftgate motor or hinges. These noises often mean that parts are worn or damaged.
4. Not Latching Properly
The liftgate may not close all the way or may pop back open after closing. This is often due to a problem with the latch mechanism or misalignment.
5. Warning Light Or Error Message
Some RX 350 models show a warning light or message on the dashboard if there is a problem with the liftgate. This can help you identify the issue early.
6. Power Liftgate Opens Or Closes On Its Own
A few owners have reported that the liftgate operates by itself without pressing any button. This can be caused by a faulty switch or electrical short.

Main Causes Of Power Liftgate Problems
Understanding what causes these issues can help you prevent or fix them.
- Weak or Dead Battery: The liftgate needs electricity. If the car battery is weak, the liftgate may not work correctly.
- Faulty Motor: The motor that opens and closes the liftgate can wear out over time.
- Broken Struts: The gas struts help hold the liftgate up. If they are weak or leaking, the liftgate may not stay open or may move slowly.
- Damaged Wiring: Wires that connect the liftgate to the car’s electrical system can break or corrode.
- Bad Switches or Buttons: The buttons used to control the liftgate can fail due to wear or moisture.
- Obstructions: Dirt, ice, or objects can block the liftgate’s path, causing it to stop or move incorrectly.
- Sensor Issues: The liftgate uses sensors to detect obstacles. If these sensors are dirty or damaged, the liftgate may not operate safely.
Troubleshooting Lexus Rx 350 Power Liftgate Problems
If your liftgate is not working, try these steps before visiting a mechanic:
Check The Battery
A weak battery is a common cause of liftgate problems. If your car is slow to start or has dim lights, the battery may be the issue. Try replacing the battery or charging it fully.
Inspect The Fuses
The power liftgate has its own fuse in the fuse box. If the fuse is blown, the liftgate will not work. Check your owner’s manual for the fuse location and replace it if needed.
Clean The Sensors And Struts
Dirt or debris on the sensors can cause the liftgate to stop or reverse. Wipe the sensors and struts with a clean cloth. If you see oil leaking from the struts, they may need to be replaced.
Test The Buttons
Press the button on the key fob, inside the car, and on the liftgate itself. If only one button does not work, it may be broken and needs replacement.
Remove Obstructions
Make sure nothing is blocking the liftgate. Even a small item can stop it from working.
Cost Of Repairing Lexus Rx 350 Power Liftgate Problems
The cost to fix a power liftgate varies depending on the problem:
- Fuse replacement: $10–$20
- Liftgate struts: $50–$150 each (plus labor)
- Liftgate motor: $200–$400 (plus labor)
- Wiring repair: $100–$300
- Switch or button replacement: $50–$100
Labor costs can add $100–$300 more, depending on your location and the repair shop.
Diy Fixes Vs. Professional Repair
Some simple problems, like a blown fuse or dirty sensors, can be fixed at home with basic tools. Replacing struts is also possible for people with some mechanical skills. However, issues with the motor, wiring, or sensors often require a professional mechanic.
Attempting complex repairs without proper knowledge can cause more damage.

Lexus Rx 350 Power Liftgate Reliability Over The Years
The RX 350 has used power liftgates for many years, but reliability can vary by model year. Early models (2007–2012) reported more issues, while newer models (2016+) have improved electronics and fewer complaints.
Here is a comparison of common liftgate problems by model year:
| Model Year | Common Issues | Average Repair Cost |
|---|---|---|
| 2007–2012 | Motor failure, slow movement | $300–$500 |
| 2013–2015 | Sensor errors, latch problems | $200–$400 |
| 2016–2021 | Button malfunction, minor wiring | $100–$300 |
| 2022+ | Rare, mostly software updates | $50–$150 |
Preventing Power Liftgate Problems
Keeping your liftgate working smoothly is possible with regular care:
- Clean the sensors and struts every few months.
- Check for leaks in the struts and replace if needed.
- Avoid slamming the liftgate shut; use the power button instead.
- Keep the liftgate path clear to prevent jams.
- Test all buttons regularly to ensure they work.
- Keep the battery charged for reliable operation.
Non-obvious Insights Most Owners Miss
Many RX 350 owners do not realize that:
- Software updates can fix some liftgate issues. Lexus dealers sometimes release updates that improve how the liftgate works. If your RX 350 is under warranty, ask your dealer about available updates.
- Weather effects: Cold weather can make the liftgate move slowly or even stop working. The grease inside the struts can become thick in low temperatures. Waiting for the car to warm up or using a silicone-based lubricant can help.
When To Replace Vs. Repair
If your liftgate is consistently failing, consider the cost of repair versus replacement. For older RX 350 models, it may be more cost-effective to replace the motor and struts together. For newer models, small parts like switches or sensors are often the culprit.
Here’s a quick guide:
| Problem | Repair | Replace |
|---|---|---|
| Blown fuse | Yes | No |
| Weak struts | Yes | Maybe (if both are bad) |
| Broken motor | No | Yes |
| Wiring issues | Yes | No |
| Button/switch problem | Yes | No |
How To Reset The Lexus Rx 350 Power Liftgate
Sometimes, a simple reset can fix minor electronic glitches:
- Open the liftgate manually.
- Locate the power button on the bottom edge of the liftgate.
- Hold the button for 3–5 seconds until you hear a beep.
- Close the liftgate and test the power function.
This reset can help after a battery change or when the system seems confused.
Warranty Coverage For Power Liftgate Repairs
If your RX 350 is still under warranty (usually 4 years/50,000 miles), most power liftgate repairs are covered. Always check with your dealer before paying for repairs. Some certified pre-owned vehicles also have extended warranties that cover liftgate issues.
Comparing Lexus Rx 350 Power Liftgate With Competitors
