Having trouble with your EZGO RXV golf cart? Whether it’s not starting, driving erratically, or showing strange behavior, this guide will help you understand the most common EZGO RXV problems and how to fix them step by step.
Battery issue? Before you spend big on replacements, learn how to recondition your golf cart batteries at home and save hundreds. This DIY method works on most lead-acid battery systems—including the RXV.
Introduction
The EZGO RXV (released in 2008) is a popular electric golf cart known for its speed, regenerative braking, and AC motor. But while it’s built for performance, the RXV comes with some unique quirks and issues. Let’s go over what RXV owners commonly face and how you can get your cart back in top shape.
1. EZGO RXV Won’t Move
If your RXV turns on but won’t drive:
- Parking brake locked: The RXV has an electric parking brake that can fail or stick. This prevents the cart from moving.
- Faulty brake controller or encoder: If the brake isn’t releasing properly, the motor won’t engage.
- Battery issue: Low voltage can trigger safety lockouts.
Fix:
- Check battery pack voltage (should be around 50–52V for 48V systems).
- Listen for brake engagement/disengagement clicks when turning the key on/off.
- Replace the brake module if it stays locked.
Tip: If your battery seems weak, try reconditioning it instead of buying new ones. It’s a proven method to revive dead or fading golf cart batteries.
2. RXV Runs Then Stops Suddenly
This frustrating issue usually ties back to:
- Loose battery cables or terminals
- Brake controller failure
- Intermittent throttle sensor (pedal box) issue
Fix: Check all cable connections, clean any corrosion, and inspect the pedal assembly wiring. Replace the brake module or throttle sensor if needed.
3. Cart Won’t Turn On
If the RXV doesn’t power on at all:
- Bad run/tow switch: Common on older models. Try flipping it back and forth several times.
- Faulty key switch or loose wires behind the dash
- Failed controller: Especially if no solenoid click is heard.
Fix: Use a voltmeter to test battery voltage and trace power from the switch to the controller. Replace the run/tow switch if it’s unresponsive.
4. Regenerative Braking Issues
RXVs use regenerative braking, which can cause problems if the system fails:
- Cart stops too abruptly or rolls freely on hills
- Brake locks up even when parked
- Error codes appear on diagnostic tools
Fix: Inspect the motor encoder and brake assembly. If the cart rolls when turned off, your brake or encoder is likely faulty.
5. Battery Drains Too Quickly
If your RXV doesn’t hold a charge or slows down too soon:
- One or more weak batteries dragging down the pack
- Faulty charger or charging port
- Parasitic draw (radio, lights, etc.) left on
Fix:
- Test each battery with a voltmeter (should be 8.3V+ per 8V battery)
- Check for voltage loss after 12–24 hours
- Recondition your weak batteries before replacing them
6. EZGO RXV Error Codes (Using Diagnostic Tools)
| Code | Description | Fix |
|---|---|---|
| HPD | High Pedal Disable | Release accelerator before turning the key on |
| LOW VOLT | Low battery voltage | Recharge or recondition batteries |
| PSW | Pedal Switch Error | Replace pedal box or sensor |
| MAIN CTRL | Controller fault | May require controller reset or replacement |
How to Reset an EZGO RXV Controller
- Turn off the key and place the cart in TOW mode
- Disconnect the main negative battery cable
- Wait at least 5 minutes
- Reconnect the battery, set the cart back to RUN, and try again
Maintenance Tips to Prevent Future Problems
- Charge the battery after every use
- Check tire pressure monthly
- Clean terminals every 30 days
- Update software/firmware if you have a Navitas controller upgrade
- Store the cart in a dry, sheltered area

Conclusion
The EZGO RXV is a fast and efficient golf cart, but it comes with unique electronic systems that can fail or cause confusion. Most issues stem from the brake system, battery health, or controller miscommunication. With the right tools and some basic checks, you can diagnose and fix many RXV problems yourself.
Don’t forget: Weak batteries cause more than 50% of RXV performance problems. Before replacing, try this at-home battery reconditioning method and restore your cart’s range and speed.
