Re: 2016 rxv Intermittent clunk/thump at start
If you find a solution, please post. Mine is doing the same thing. Feels like someone hit me when I start moving but not every time. I havent addressed it yet but I will say I had my motor out not long ago and noticed the splines on my input shaft (shaft from rear end to motor) looked pretty chewed up. I dont know if that could be my issue or not, but I'll probably start there.

Replace the input shaft, it's cheap ($ 70) and easy to do (except removing the heavy Motor).

Re: 2016 rxv Intermittent clunk/thump at start
I drove the cart on the golf course today. Twice it did a shudder, not really a clunk. The day before I did remove the bolts and shackles and made sure all bushings were in good shape and tighten all bolts to factory specs.
I hooked up scanner after round and saw two errors. HPD/sequencing fault Comms supervision Working on the troubleshooting guide to track these errors down and do some testing. |

Replaced the throttle position sensor and throttle switch. Cart did the shudder once while playing 18 holes of golf yesterday.
Still searching for the cause. |

Re: 2016 rxv Intermittent clunk/thump at start
Still getting the shudder. Happened 6 times on the golf course yesterday.
I still think it has something to do with the cart not releasing the brake when you press the gas pedal. We have replaced the brake with a known working brake, no change. Very frustrating. |

Saw these errors using my handheld scanner.

From Curtis Troubleshooting Guide :
SUPERVISOR COMMS Supervisor fault No Action Condition clears 1. Communication error 2. Check for HPD fault 3. This may happen after controller sleep mode 45 THROTTLE WIPER Pedal input (16) voltage is out of active range Shutdown Throttle Voltage recovers to active range 1. Throttle pot wiper voltage too low (< 0.35V) 2. Throttle pot wiper voltage too high (> 4.8V) 3. Verify sensor operation on hand held 4. Check pedal operation 45 |
