Mg4 Software Update May 2026

One of the biggest complaints regarding early MG4 models was the overly aggressive Lane Keep Assist system. It would often tug at the steering wheel unnecessarily or struggle with faded road markings.

The MG4 has taken the electric vehicle market by storm, offering exceptional range and performance at a competitive price point. However, like many modern EVs, the driving experience is heavily reliant on software. Since its launch, MG has rolled out several "Over-the-Air" (OTA) updates to refine the vehicle.

Whether you are a new owner waiting for your first update or a long-term driver frustrated by specific bugs, this guide covers the current state of MG4 software updates, how to install them, and what changes they bring.

The primary goal of recent software updates has been to address "teething issues" reported by the early adopters of the MG4. Here are the major changes introduced in the R33 update and subsequent patches:

Software updates for the have evolved from addressing critical safety bugs to enhancing the driving experience, though the process remains largely tied to physical dealership visits. Current State of MG4 Software Updates (April 2026)

While many modern EVs utilize Over-the-Air (OTA) updates, most MG4 models still require a manual installation performed by a technician at an authorized dealership.

Rollout Strategy: MG has announced plans to roll out OTA updates progressively, starting with "IM" vehicles. The MG4 is expected to be among the last to receive full OTA functionality due to its high sales volume and the need for rigorous quality assurance.

Dealer Policy: Many dealerships only apply updates if a customer explicitly reports a problem, such as "ghost braking" or infotainment glitches.

Installation Time: A comprehensive update of all modules (e.g., BMS, BCM, and Infotainment) can take 4 to 8 hours, often requiring the car to be left at the shop for a full day. Major Software Versions and Improvements

Several key updates have addressed the most common complaints from early MG4 adopters. R59 / R11 (The "Big" Update) mg4 software update

Released in late 2023 and early 2024, this version was a major milestone for refinement.

Lane Keep Assist (LKA): Added a swipe-down shortcut on the touchscreen to quickly disable the system, which many found too aggressive.

Adaptive Cruise Control (ACC): Improved predictability and added a memory function for the last-used distance setting.

One-Pedal Driving: Introduced one-pedal functionality for the base Excite 51 variant.

Stability: Fixed Bluetooth connection drops and intermittent radio fading. ADAS & Safety Calibrations (2025 Updates)

Software updates for the MG4 are essential for fixing common performance and safety issues, but the process currently requires visiting a dealer. While the vehicle's architecture is designed for Over-the-Air (OTA)

updates, most owners currently must have them installed manually by a technician. Key Issues Fixed by Recent Updates

Updating your MG4 software can resolve several widely reported "bugs" and improve the overall driving experience: Safety Features : Significant updates address Phantom Braking (AEB) and harsh Lane Keep Assist (LKA) behaviors. Driving Dynamics : Updates can enable or improve One-Pedal Driving (OPD)

settings and refine Cruise Control to allow 1km/h increments instead of 5km/h. Climate & Infotainment One of the biggest complaints regarding early MG4

: Fixes "unpredictable" climate control behavior and resolves screen glitches, such as those occurring with Apple CarPlay or 360° cameras. Battery Management

: Updates often include optimizations for the battery management system and charging performance. How to Get an Update

Because updates are not yet automatic for many users, you should be proactive during your next service: What is the latest software update for MG4?

Scheduled charging now works reliably. The car finally respects your off-peak electricity hours (e.g., 12 AM – 5 AM) without randomly stopping.

The substantial updates—the ones that fix the driving experience—must be done by a dealership using a laptop plugged into your OBD port. This is called SIPS (Service Information & Programming System) . A full dealer update can take anywhere from 45 minutes to 3 hours. Do not assume your car is updated just because you bought it recently. Cars sitting on lots for six months have old software.

If you browse MG owner forums, you will see endless chatter about version numbers like R46, R59, R63, and the latest, R70 (varies by market; EU/UK spec differs from Australian/Thai spec). The infotainment version is usually found in Settings > System > About.

Here is the evolution of the MG4 experience via infotainment patches:

How to check your version: Tap the "MG" icon in the lower left of the screen > select "Settings" (the gear icon) > scroll to "System" > "About." If the last two digits are below "59," you are due for a service visit.
