MG4 MY23: Reduced range and weaker acceleration in cold conditions or at low charge
Range decreases in cold conditions; acceleration or power is reduced at extreme temperatures and low charge.
MG4 MY23: Reduced range and weaker acceleration in cold conditions or at low charge
Symptoms
- Range decreases in cold conditions; acceleration or power is reduced at extreme temperatures and low charge. [1]
Possible causes
- The manual associates these behaviours with battery temperature characteristics, state of charge, A/C load and driving conditions; do not use them to judge degradation or failure rates. [1]
Checks
- Compare temperature, SOC, A/C load, tyre pressure and driving conditions; charge promptly using suitable equipment when the low-charge light illuminates. [1]
What to do
- Follow the manual to drive smoothly, maintain correct tyre pressures and reduce unnecessary electricity use; if separate fault warnings appear, inspect and repair in accordance with the corresponding warning. [1]
Applicability and limits
- Source limits: MG MG4, model year 2023, European MY23 English-language manual; distinguish normal operating characteristics from faults; this entry does not claim to explain every sudden drop in range. For inspection guidance only; related parts do not constitute a recommendation to replace them. No vehicle model is linked; do not assume applicability to other models of the same brand. Scope: unknown [1]
