On the 2012-2020 Renault Twizy, a very common Twizy fault is discharge or failure of the small 12V auxiliary battery, which prevents the vehicle from waking up its control modules and closing the main traction battery contactors. Owners report the car appearing completely dead, showing charging faults, or refusing to select drive after sitting unused; the issue is often caused by an aging AGM battery, parasitic drain, or long storage without a maintainer.
Diagnosis starts with checking resting 12V voltage and load-testing the auxiliary battery; anything significantly below about 12.4V after charging usually points to replacement. Inspect battery terminals, ground points, and DC-DC charging operation, then replace the 12V battery if weak; typical battery cost is about $80-$180, with total repair usually $100-$250 including labor. If the battery repeatedly goes flat, owners also check for charger/DC-DC faults and use a maintenance charger during storage.

On the 2012-2020 Renault Twizy, twizy owners frequently report charging faults where the car will not begin charging, stops partway through, or shows a charging system warning. The problem is commonly linked to the on-board charger, charging cable/inlet issues, moisture intrusion, or low 12V system voltage preventing the charger and battery management system from operating correctly.
Diagnosis involves confirming mains supply quality, inspecting the integrated charge cable and plug for heat damage, checking the charge inlet and wiring for corrosion, and scanning Renault-specific EV modules for charger faults. Repairs range from cleaning connections or replacing the charge cable components to replacing the on-board charger assembly; minor fixes may cost $150-$400, while charger replacement can run roughly $1,000-$2,500 depending on parts source and labor.

On the 2012-2020 Renault Twizy, a known owner-reported issue on higher-mileage Twizys is whining, rumbling, or grinding from the rear drivetrain area. The noise is usually traced to electric motor bearings or the reduction gearbox bearings/gears, accelerated by age, water exposure, and constant urban stop-start use.
Road-test the vehicle to isolate whether the noise changes with speed or load, then inspect the motor/reduction unit and rear hub area for bearing play and lubricant contamination. Repair may involve replacing motor bearings, rebuilding the reduction unit, or fitting a used/reconditioned drive assembly; costs typically range from about $400 for bearing work to $2,000 or more for a complete assembly swap.

On the 2012-2020 Renault Twizy, because the Twizy is light, uses regenerative braking, and is often driven short distances, its friction brakes can corrode from lack of use. Owners commonly report sticking calipers, seized slide pins, dragging brakes, and uneven pad wear, especially after storage or wet-weather use.
Inspect pad thickness, rotor condition, caliper piston movement, and slide pin lubrication on all corners. Repairs usually involve cleaning and lubricating hardware, replacing seized pins or calipers, and fitting new pads/rotors if corrosion is advanced; expect about $150-$350 for service work, or $300-$700 if calipers and discs are needed.

On the 2012-2020 Renault Twizy, the Twizy's half-door and open-sided design makes it prone to water ingress, rattles, and latch wear. Owners report rain entering around the optional side windows and doors, difficulty latching or opening the scissor doors, and increased cabin noise from worn seals and misadjusted hardware.
Inspect door hinges, latch alignment, striker position, and the condition of seals and window panels. Repairs usually involve adjusting the latch/striker, replacing worn seals or fasteners, and lubricating hinges and locks; costs are often $50-$250 for adjustment and minor parts, but damaged door hardware can push repairs toward $400 or more.
