What You Need to Know About This Important Safety Update

If you're riding or wrenching on a SYM FNX 125/150 or Jet X 150, listen up. On November 6, Sanyang Motor (SYM) announced a voluntary recall affecting around 8,500 units from the 2024 and 2025 model years. The issue? A potential problem with the fuel pump seal that could lead to leaks, causing the engine to stall unexpectedly or, in rare cases, pose a fire risk. It's not something to ignore, but SYM is handling it proactively with free fixes. Let's break it down so you know exactly what to do next.

Which Models and VINs Are Affected?

This recall targets specific SYM scooters:

FNX 125 and FNX 150 (2024-2025)
Jet X 150 (2024-2025)

The affected vehicles have these vehicle identification number (VIN) ranges:

Starting with RLJTCBxxExxxxxxxx
Up to RLJTCDxxFxxxxxxx

If your scooter's VIN matches, you're in the group. SYM has made it easy to check this — head to their official dealer portal or call your local authorized service center. No need to guess; they'll confirm in minutes.

What's the Problem and Why Does It Matter?

The culprit is the fuel pump seal. Over time, it might not hold up perfectly, allowing fuel to seep out. Riders have reported symptoms like random engine shutdowns while riding, a sudden loss of power, or even a faint fuel smell. In worse scenarios, a leak could ignite if it contacts hot engine parts. SYM caught this through their quality monitoring and decided to act before any major incidents piled up. Safety first, right? As a mechanic, I've seen how these seals can degrade faster in the humid climate or with frequent stop-go traffic in cities like Taipei or Kaohsiung.

How to Get It Fixed—It's Free and Straightforward

Starting November 11, authorized SYM dealers will replace probably the fuel pump assembly at no cost to you. The job takes about an hour, and they'll use updated parts with better seals. Plus, SYM is rolling out new diagnostic codes to make spotting this issue quicker during routine checks.

If your customer brings in a scooter with "random stalling" complaints, prioritize checking the fuel pump—don't wait for the official recall notice. In the meantime, advise riders to avoid riding if they notice fuel odors or inconsistent performance, and tow it in if needed.

Tips for Mechanics and Riders

As someone who's turned a wrench on countless SYM models, here's the advice:

Update your diagnostic tools with the latest SYM software to catch those new error codes.
Stock up on related parts if you're an independent shop, but for recall work, stick to official channels.
This is a great reminder to chat with customers about regular maintenance—clean fuel systems and timely inspections can prevent a lot of headaches.

SYM has a solid track record with these voluntary actions, and this one shows they're on top of things. No reported injuries so far, which is a win.
