Is your EZGO RXV acting up? Whether it won’t start, moves slowly, or stops unexpectedly, this guide will walk you through how to diagnose and fix the most common EZGO RXV issues—without needing a technician.
Battery issues? Don’t replace them just yet. Try this easy battery reconditioning method to bring your golf cart batteries back to life and save hundreds of dollars.
About the EZGO RXV
The EZGO RXV (Rear CrossView) is a popular golf cart model known for its advanced AC drivetrain and Intellibrake technology. It comes in electric (48V AC) and gas versions. While reliable, RXVs are complex machines that can develop problems over time—especially electrical ones.
Common EZGO RXV Electric Problems and How to Fix Them
1. EZGO RXV Won’t Move (No Click or Response)
If your RXV is completely unresponsive when you turn the key:
- Dead battery pack: Needs at least 38–40V to power up the controller.
- Bad run/tow switch: Switch might be corroded or stuck.
- Seat switch or brake interlock issue: If either fails, the cart won’t run.
- Blown fuse or controller lockout: Check the inline fuses near the controller.
Fix: Charge the battery pack and test voltage across the main terminals. Reset the run/tow switch by flipping it to “Tow” for 10 seconds, then back to “Run.” If still dead, test the key switch and seat sensor for continuity.
Low voltage? Recondition your batteries at home before replacing them—it could save you $700+.
2. RXV Moves But Suddenly Stops
This can be caused by:
- Overheating motor or controller
- Faulty brake module (Intellibrake)
- Intermittent key switch or throttle sensor
Fix: Let the cart cool down. Then inspect the brake module for resistance. A bad brake often stops the cart mid-drive. You may also need to test the pedal throttle switch (ITS) with a voltmeter.
3. Cart Jerks When Starting
This typically means:
- Bad accelerator pedal sensor
- Loose or dirty battery connections
- Speed sensor failure
Fix: Clean all battery and motor cables. Test the speed sensor by jacking up the rear wheels and slowly pressing the accelerator—if the wheels jerk or jump, the sensor may be failing. Replace it if necessary.
4. EZGO RXV Brake Won’t Release
The RXV uses an electric parking brake (Intellibrake) that automatically engages when the cart is off. If the brake doesn’t release when you turn the key:
- Controller isn’t getting power
- Brake module is faulty
- Run/tow switch is off
Fix: Confirm the cart is in “Run” mode and batteries are charged. If the brake hums but won’t disengage, it’s likely bad. You’ll need a brake module replacement or a handheld programmer to release the brake safely.
EZGO RXV Gas Model Troubleshooting
1. Gas RXV Won’t Start
Causes include:
- Bad battery (12V)
- Clogged fuel line or dirty carburetor
- No spark at plug
Fix: Charge or replace the 12V battery. Clean carburetor and check fuel flow. Replace spark plug and inspect ignition coil if needed.
2. Engine Turns Over But Won’t Run
This could be a fuel delivery or ignition issue:
- Clogged fuel filter
- Weak fuel pump
- Faulty igniter or coil
Fix: Check fuel pressure, replace filter, and test spark output using a tester tool. Repair or replace parts as needed.
EZGO RXV Diagnostic Tools
EZGO RXV electric carts can display fault codes using a handheld programmer or diagnostic tool. Codes are useful for diagnosing:
- Brake module issues
- Controller errors
- Throttle or motor faults
For DIYers, use a multimeter to test the motor, brake, and throttle sensors manually. There are also online controller fault code charts if you can access the blinking LED inside the controller casing.
Battery and Voltage Tips for RXV
- 48V system: Normal full voltage is 50.9V–51.2V
- Each 8V battery should read 8.4V when charged
- If any battery drops below 7.5V, it can trigger controller errors
Instead of replacing weak batteries, try this DIY battery reconditioning method to bring them back to life at home.
Preventive Maintenance Tips
- Check run/tow switch monthly for wear
- Keep battery terminals clean and tight
- Update firmware on newer RXV controllers
- Clean motor and controller area to prevent overheating
When to Replace the Controller
Replace the RXV controller if:
- No output to motor despite good inputs
- Persistent fault codes after resets
- Brake won’t disengage and motor tests good
Controllers are expensive. Be sure to test your batteries and recondition them first before spending $500+.

Conclusion
The EZGO RXV is advanced, but its electronic systems can be sensitive. Most issues stem from low battery voltage, faulty sensors, or controller communication failures. With this guide, you can troubleshoot and fix many problems yourself—saving time and money.
Before replacing batteries or expensive parts, try battery reconditioning at home. It’s safe, easy, and could bring your RXV back to life without spending hundreds.
