The Maxus eTerron 9 is one of SAIC’s newest electric pickups to hit UK roads, but like any working vehicle it has its share of teething problems. The most common issue owners report is unexpected 12v auxiliary battery drain – not range anxiety, but the low-voltage system going flat overnight or after short periods parked up.

Key Facts – Maxus eTerron 9 Problems

  • Most reported issue: 12v battery drain when parked – the main unexpected problem for electric van and pickup owners
  • Parts identification: ‘eTerron 9’ alone is not enough to confirm the correct part – your VIN or registration is needed
  • Brand confusion: The eTerron 9 is built by SAIC Motor – some owners search under both Maxus and LDV branding
  • Genuine parts: OEM SAIC Maxus parts are available from UK stock with fitment confirmed before dispatch

12v Battery Drain – The Number One eTerron 9 Complaint

Electric vehicle owners – whether driving the eTerron 9 pickup or the eDeliver range of vans – consistently report 12v auxiliary battery drain as their biggest unexpected headache. While most buyers worry about driving range before purchasing, it is the small 12v battery that causes real-world frustration.

The 12v battery powers the vehicle’s control systems, central locking, lights and onboard computers. When it drains flat, the vehicle may refuse to start, lock or unlock, or display a string of warning lights on the dash. This can happen after the vehicle has been parked for just a few days without use.

What to check first:

  • Ensure the main high-voltage battery has adequate charge – the 12v system tops itself up from the main pack, but only when certain conditions are met
  • Look for parasitic draws – aftermarket trackers, dashcams or telematics units wired to permanent live feeds are a common culprit
  • Check the 12v battery condition itself – a weak or ageing cell will not hold charge even when the vehicle’s charging system is working correctly
  • Have the body computer (BCM) checked for software updates at your dealer – some early units had module wake-up issues

If the 12v battery needs replacing, always fit the correct OEM specification. You can look up genuine eTerron 9 parts by your registration or VIN to confirm the exact battery and component specifications for your vehicle.

Parts Identification – Why Your VIN Matters

A common mistake eTerron 9 owners make is assuming the model name is enough to order the right part. It is not. SAIC builds these vehicles across different production runs, and components – from body panels and lighting units to control modules and suspension parts – can differ depending on your exact build date, specification level and market variant.

Your VIN (Vehicle Identification Number) or UK registration is the only reliable way to confirm fitment. We check every order against your vehicle’s details before dispatch, so you receive the correct genuine SAIC part first time. If you are not sure where to find your VIN, it is stamped on a plate visible through the lower windscreen on the passenger side and printed on your V5C document.

You can use our VIN lookup tool to identify the exact parts your eTerron 9 needs.

Maxus or LDV – Which Brand Is My Vehicle?

This causes real confusion. The eTerron 9 is manufactured by SAIC Motor and sold under the Maxus brand in the UK. However, many owners – particularly those familiar with older LDV vans – search for parts under both the Maxus and LDV names. They are effectively the same manufacturer lineage, and genuine parts come from SAIC regardless of which badge sits on the tailgate.

Whether you search for Maxus eTerron 9 parts or LDV parts, the components are genuine SAIC OEM items. Our parts catalogue covers over 43,000 genuine parts across the full Maxus range including the eTerron 9, Deliver 3, 5, 7 and 9, eDeliver models, T60, T90, MIFA 9, V80 and A80.

Other Reported eTerron 9 Issues

Infotainment and software glitches: Some owners report occasional screen freezes or slow response from the central touchscreen. A full system restart – switching the vehicle off, waiting two minutes, then restarting – usually resolves temporary glitches. Persistent issues may need a software update via the dealer network.

Trim and fit quality: As a relatively new model to the UK market, some early eTerron 9 pickups have shown minor trim rattles or fitment issues with interior panels. Replacement clips, fasteners and trim pieces are available as genuine parts.

Charging port door mechanism: A small number of owners have reported the charging flap sticking or not releasing cleanly in cold weather. Check the latch mechanism and hinges for debris or ice build-up before assuming a part failure.

Frequently Asked Questions

Why does my eTerron 9 12v battery keep going flat?

The 12v auxiliary battery in electric vehicles works harder than in a traditional diesel van. It powers all the control electronics even when the vehicle is parked. Aftermarket accessories, infrequent use, or a battery past its best are the usual causes. Fit the correct OEM replacement and remove any aftermarket devices wired to permanent live circuits.

Can I use LDV parts on my Maxus eTerron 9?

The eTerron 9 is a Maxus-branded SAIC vehicle, so you need genuine SAIC Maxus parts. Older LDV-branded components from different models will not fit. Always confirm fitment using your VIN or registration number – model name alone is not sufficient.

Where do I find my eTerron 9 VIN number?

Your VIN is on a plate visible through the base of the windscreen on the passenger side. It is also printed on your V5C registration document and often on a sticker inside the driver’s door jamb. You will need this 17-character code to confirm the correct parts for your specific vehicle.

Are genuine Maxus parts available in the UK?

Yes. We stock over 43,000 genuine SAIC Maxus OEM parts at our Tibenham, Norfolk warehouse with UK-wide FedEx delivery. Every part is checked against your vehicle details before dispatch to confirm correct fitment. Trade accounts are available for garages and fleet operators.

My eTerron 9 is showing warning lights after the 12v battery went flat – is something broken?

Usually not. When the 12v battery drops too low, various control modules lose power and log fault codes. Once a fully charged or new 12v battery is fitted, most warning lights clear after a short drive cycle. If any lights persist, have the fault codes read – the body computer may need a reset.
