2024 BMW i4 problems
A 2024 BMW i4 is now 2 years old, so an average example has covered around 27,000 miles. A late-run car · the most reliable part of the generation, but higher-mileage wear items are usually the deciding factor. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2024 car has usually reached the mileage where they appear.

Quick answer
The 2024 BMW i4 is 2 years old, so an average example has covered roughly 27,000 miles. At that mileage 1 of the documented faults are already due, so check those first. A further 6 typically appear later in the car's life.

- Typically appears
- 40,000+ miles
- What to inspect
- Check the vehicle battery health readout and charging history
SuspensionMedium
Bush and damper wear from kerb weight
- Typically appears
- 50,000+ miles
- What to inspect
- Listen for knocks and check for damper weeping
HVAC SystemHigh
Lack of cabin heating or cooling due to heat pump changeover valve failure.
- Typically appears
- 20,000-40,000 miles
- What to inspect
- Set the climate control to maximum heat, then maximum cold. Verify a rapid and distinct temperature change at the centre vents within 60 seconds.
Exterior BodyMedium
Charge port flap fails to open or lock shut due to a faulty locking actuator.
- Typically appears
- 10,000-30,000 miles
- What to inspect
- Lock and unlock the vehicle using the key fob, then press the charge flap to ensure it springs open smoothly and latches securely when pushed closed.
Doors and WindowsMedium
Frameless window glass fails to drop slightly when pulling the door handle, snagging the roof trim.
- Typically appears
- 30,000-50,000 miles
- What to inspect
- Open and close all four doors rapidly. Watch the top edge of the glass to ensure it drops 5mm instantly upon pulling the handle and raises fully when shut.
Cooling SystemHigh
High-voltage system coolant leaks at the heat exchanger or Combined Charging Unit (CCU).
- Typically appears
- 15,000-40,000 miles
- What to inspect
- Open the bonnet, remove the plastic acoustic cover, and visually inspect the two coolant expansion tanks for correct fluid levels and any dried white crusting around the hoses.

Build my inspection planBMW i4 · frequently asked questions
What matters most on an EV?
Battery state of health. Get the readout in writing before you buy.
Are brakes an issue?
Rust more than wear. Discs often fail an inspection before pads do.
Do software versions matter?
Yes, older builds miss charging and range improvements.
What should I look out for regarding tyre wear on the i4?
The i4's high torque and kerb weight accelerate rear tyre wear, particularly on the M50 dual-motor variant. Check the inner edges of the rear tyres carefully, as aggressive factory camber settings can hide severe wear from a casual outer-edge glance. Always ensure replacement tyres are EV-rated.
What are the routine servicing requirements and intervals for this model?
BMW operates a condition-based servicing system, but the i4 typically requires a brake fluid change and cabin microfilter replacement every two years, regardless of mileage. The vehicle will prompt when a general vehicle check is due. Ensure the digital service history on the iDrive system is fully up to date.
Which charging cables should be present in the boot?
A UK-supplied i4 should come with a Type 2 to Type 2 public charging cable and a standard 3-pin domestic charger. Check the under-floor storage in the boot, as these cables are expensive to replace and frequently go missing before the car reaches the forecourt.
