2016 BMW i3 problems

A 2016 BMW i3 is now 10 years old, so an average example has covered around 135,000 miles. An early car in the generation · most of the launch teething issues were still being worked through, so recall completion and dealer rectification history matter. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2016 car has usually reached the mileage where they appear.

Quick answer

The 2016 BMW i3 is 10 years old, so an average example has covered roughly 135,000 miles. At that mileage 4 of the documented faults are already due, so check those first.

Faults a 2016 example has usually reached

Documented onset mileage is at or below the ~135k miles an average 2016 car has covered.

SuspensionMedium

Narrow tyre availability and rear bush wear

Typically appears
60,000+ miles
What to inspect
Check tyre condition and source availability before pricing
DrivetrainHigh

Rear end clunking under acceleration or regen braking due to sheared plastic motor mount brackets (primarily pre-2016 models).

Typically appears
40,000-70,000 miles
What to inspect
Accelerate sharply to 15 mph and lift off abruptly to trigger heavy regen braking. Listen for a loud metallic clunk from the rear axle.
HVAC / Battery CoolingHigh

AC compressor failure, which can send metal swarf into the high-voltage battery cooling loop, causing catastrophic battery damage.

Typically appears
50,000-80,000 miles
What to inspect
Set climate control to 'Lo' with max fan. Listen at the front bumper for loud mechanical whining and ensure vents blow ice-cold air within 60 seconds.
Front SuspensionLow

Creaking or knocking noises when steering, caused by perished top strut mounts and split shock absorber dust boots.

Typically appears
30,000-60,000 miles
What to inspect
Turn the steering wheel lock-to-lock while stationary to listen for creaks. Shine a torch into the front arches to check for torn rubber damper boots.

Faults that appear at any mileage

Age, electronics and build-related issues that are not mileage-driven.

BatteryCritical

Capacity differences between 60Ah, 94Ah and 120Ah cars

Typically appears
Any
What to inspect
Confirm the battery version and run a state-of-health check
EngineHigh

Range extender fuel system faults from lack of use

Typically appears
Any
What to inspect
On REx cars, start the generator and check it runs cleanly
BodyHigh

Carbon body repair complexity after accident damage

Typically appears
Any
What to inspect
Check the history for accident repairs and inspect panel gaps
ElectricalMedium

Spurious 'Drivetrain Malfunction' errors, locked charging cables, or complete vehicle immobilisation due to a degraded 12V battery.

Typically appears
Every 3-4 years
What to inspect
Open the bonnet, unclip the plastic storage tub, and check the date stamp on the 12V battery. If older than four years, budget for replacement.

BMW i3 · frequently asked questions

Which i3 should a dealer buy?

The 120Ah cars. Range on early 60Ah examples is now too short for most buyers.

Is the range extender a problem?

Only when unused. Fuel system issues appear on cars where the generator never runs.

Why does accident history matter more here?

The carbon structure needs specialist repair, so poor previous work is both a safety and a value issue.

How can I check the high-voltage battery health on the forecourt?

You can access the hidden service menu via the instrument cluster. Hold the trip reset button, sum the last five digits of the VIN to unlock it, and navigate to the 'Batt. Kapa. max' menu. This displays the usable battery capacity in kWh, giving a quick snapshot of degradation without diagnostic tools.

What is the KLE unit and why is it a common failure point?

The KLE is the onboard charger responsible for AC charging. Early units were prone to overheating and failure, limiting the car to slow charging speeds or preventing charging entirely. Always plug the car into a Type 2 fast charger on the forecourt to verify it pulls the expected 7.4kW or 11kW.

Are the rear-hinged doors a MOT or safety issue as the car ages?

The rear-hinged doors are generally robust, but the lower latches are prone to water ingress and seizing. If the latches stick, the door will not close properly, resulting in an immediate MOT failure. Check that both rear doors open smoothly and latch securely without requiring excessive force.
