7.7/10
1 walk-away risk, 7 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: high-voltage battery cell/module recalls. Score methodology.
The BMW i4 is one of the best-driving used EVs because it feels like a 4 Series first and an EV second, but early cars carry real recall and software baggage. The expensive traps are high-voltage battery recalls 22V-541 and later module recalls, 23V-449 combined charging unit failure, 25V-395 electric-drive software loss of power, coolant changeover-valve leaks, and iDrive 8/charging-session instability. The safest buy is a 2024-2025 eDrive40 or xDrive40 with all BMW recalls complete, no charging interruption history, and a clean coolant-valve campaign record. Current owners should keep software current and save recall paperwork because i4 resale depends heavily on proving that BMW's early EV campaigns are closed.

Best years
2024-2025
Best buys
- 2024-2025 eDrive40/xDrive40 with closed HV battery, CCU, and drive-motor software recalls.
- 2023-2024 eDrive35/eDrive40 as a lower-cost buy if charging and coolant campaigns are clean.
- M50 only with tyre, suspension, and high-voltage records in order.
Inspect hard
- 2022 launch cars for 22V-541 battery module replacement and stop-charge/stop-drive history.
- 2022-2023 cars for 23V-449 CCU recall and AC/DC charging behaviour.
- Cold-climate cars for coolant changeover valve leaks and low heater output.
Avoid
- Any i4 with open HV battery recall, active high-voltage warning, or seller refusing a dealer VIN printout.
- Cars with repeated charging interrupted complaints and no CCU diagnosis.
- M50s on mismatched tyres or with suspension damage.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which BMW i4 should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
70.2 kWh gross, eDrive35
2023-2025
VALUE BUY
Smaller pack and rear motor make the eDrive35 cheaper and simpler. Range is lower, but it avoids some M50 tyre and load stress. It is a good used buy if recalls are closed and the buyer does not need maximum range.
83.9 kWh gross, eDrive40
2022-2025
BEST BALANCE
The eDrive40 is the i4 sweet spot: long range, rear-drive efficiency, and less tyre abuse than M50. Early 2022 cars must be checked for battery recalls, but a clean eDrive40 is the safest high-mileage i4.
83.9 kWh gross, xDrive40
2024-2025
BEST ALL-WEATHER
The xDrive40 adds traction without the full M50 running costs. It is attractive in Nordic climates, but buyers should still inspect tyres, suspension, and coolant campaign status.
83.9 kWh gross, M50 dual motor
2022-2025
FAST BUT COSTLIER
The M50 is the emotional buy. It is also heavier on tyres, suspension, and insurance, and early examples were in the same recall/software ecosystem as other i4s. Buy on records, not launch-control appeal.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2022
Launch year for eDrive40 and M50. Earliest cars fall into 22V-541 battery recall and early software maturity period.
Buyer: Only buy with BMW proof that battery and software recalls are closed. A launch M50 without records is the highest-risk i4.
Owner: Save every campaign invoice. Your car's value depends on separating "early recall completed" from "early recall ignored."
2023
eDrive35 joins in some markets. 23V-449 CCU recall affects certain 2022-2023 cars.
Buyer: eDrive35 is good value, but CCU and charging tests matter as much as range. Do not skip the plug-in test.
Owner: If charging interruptions start, document the charger type and fault timing before the dealer visit.
2024
xDrive40 expands the range. Coolant changeover-valve and selected high-voltage battery module campaigns appear in service bulletins/recalls.
Buyer: A 2024 is a good target year once campaigns are closed. Cold-climate cars need heater and coolant-valve inspection.
Owner: Watch for low heat in winter and coolant residue under the car. Early diagnosis is much cheaper than repeated top-ups.
2025
Mature G26 i4 but included in 25V-395 electric-drive software recall population. NACS/Supercharger-access software rollout becomes a resale question in some markets.
Buyer: Newer does not mean no recall. Confirm 25V-395 status and charging-software level.
Owner: Keep Remote Software Update records. Charging-network compatibility is now part of resale value.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
High-voltage battery cell/module recalls
Affects
Selected 2022-2025 i4 depending on campaign; 22V-541 for early 2022 and later limited module recalls.
Symptoms
Stop-charge/stop-drive instruction, open recall, high-voltage warning, dealer module replacement.
Typical repair cost
$0 under recall; out-of-warranty HV battery work can be $5,000-20,000+.
Codes / scan clues
NHTSA 22V-541; 24V-135; 25V-470/related module campaigns by VIN.
Root cause: Cell/module manufacturing defects can create short-circuit, electrolyte leakage, overheating, or module-frame stress risks.
Quick check
- Run VIN through BMW and NHTSA.
- Ask for battery module replacement paperwork.
- Reject active stop-charge/stop-drive cars.
- Check pack-related warnings after charging.
Buyer note
An open HV battery recall is not a negotiation chip; it is a reason to wait.
Owner note
Do recall work promptly and keep the module paperwork.
Fault 2
Combined Charging Unit failure / 23V-449
Affects
Certain 2022-2023 i4 eDrive40 and M50, plus related BMW EVs.
Symptoms
Charging interrupted, no HV readiness, shutdown while driving, AC/DC charging faults.
Typical repair cost
$0 under recall; $3,000-7,000+ outside warranty.
Codes / scan clues
NHTSA 23V-449; BMW CCU recall; 0317F1/0317F2 insulation faults in related bulletins.
Root cause: Supplier-built CCU may be defective; CCU is central to charging and high-voltage operation.
Quick check
- Confirm 23V-449 completion.
- Test Level 2 charging.
- If possible, test DC fast-charge handshake.
- Scan CCU for insulation and charging faults.
Buyer note
Do not accept an i4 that only charges sometimes.
Owner note
Repeated charging interruption belongs at BMW with fault logs, not in forum guesswork.
Fault 3
Electric-drive software shutdown recall
Affects
2022-2025 i4 and related BMW EVs.
Symptoms
Loss of drive power risk, high-voltage system shutdown, recall open.
Typical repair cost
$0 recall software.
Codes / scan clues
NHTSA 25V-395.
Root cause: Electric drive motor software may shut down the high-voltage system, causing loss of drive power.
Quick check
- Check 25V-395 status by VIN.
- Verify latest dealer or RSU software.
- Ask about any sudden coast-down events.
- Do not rely on dashboard absence alone.
Buyer note
Software recall open on a nearly new EV is easy to fix, but it must be fixed before purchase.
Owner note
Install the remedy and keep proof; this is a resale question.
Fault 4
Coolant changeover valve leak and low heater output
Affects
2022-2024 i4, especially cold-climate cars.
Symptoms
Coolant under car, low heater output, Drive you can continue message ID49, coolant-level faults.
Typical repair cost
$0 under campaign/warranty; $800-2,000 outside.
Codes / scan clues
224163, 8049AA, 80124F, 224F60, 224111, 224107; B64 02 24 referenced by specialists.
Root cause: Coolant changeover valve can leak in very low temperatures, reducing thermal-management and heater performance.
Quick check
- Inspect under car after overnight cold soak.
- Run cabin heat on max.
- Check coolant-level faults.
- Ask for valve campaign completion.
Buyer note
In Nordic climates, heater output is a drivetrain inspection item.
Owner note
Do not top up repeatedly; get the valve diagnosed.
Fault 5
iDrive 8 black screen and software instability
Affects
2022-2024 iDrive 8 cars, less common after updates.
Symptoms
Frozen screen, reboot, CarPlay drop, driver display lag, app/route-planning errors.
Typical repair cost
$0-300 for update/diagnosis; module replacement more.
Codes / scan clues
Head-unit software faults vary.
Root cause: Early iDrive 8 software and connected-services stack matured through updates.
Quick check
- Cold boot iDrive.
- Pair phone and run navigation.
- Check RSU version.
- Ask about repeated black-screen events.
Buyer note
Software annoyance is fine after updates. Repeated frozen screens on current software need diagnosis.
Owner note
Keep RSU current and reboot only as a temporary fix.
Fault 6
Charging interruptions and EVSE compatibility complaints
Affects
2022-2025 i4, especially early software and high-amperage home EVSE use.
Symptoms
Charging started/interrupted loop, failed scheduled charge, red charger fault, public charger handshake failure.
Typical repair cost
$0 if EVSE/settings; $500-7,000 if vehicle charging hardware.
Codes / scan clues
CCU/charger faults vary; cross-check 23V-449.
Root cause: Can be home charger overheating, adapter/cable issue, software, or CCU fault. The symptom alone does not identify the cause.
Quick check
- Test on known-good Level 2 charger.
- Test lower amperage if fault appears at 40A.
- Check CCU recall.
- Save charging logs.
Buyer note
A used EV must prove reliable home charging before purchase.
Owner note
Document charger brand, amperage, and weather before the service appointment.
Fault 7
M50 tyre, wheel, and suspension wear
Affects
M50 and xDrive cars, worst on large wheels.
Symptoms
Rapid rear tyre wear, bent wheels, vibration, suspension knock, mismatched tyres.
Typical repair cost
$1,000-3,000.
Codes / scan clues
TPMS or chassis faults if severe; usually physical.
Root cause: Heavy dual-motor EV with high torque and low-profile tyres punishes consumables.
Quick check
- Inspect inner tyre shoulders.
- Check wheel runout/vibration.
- Drive over sharp bumps.
- Look for matching premium tyres.
Buyer note
M50 running costs are not eDrive40 running costs.
Owner note
Rotate if permitted, align regularly, and avoid cheap tyres.
Fault 8
High-voltage insulation faults traced to eDrive motor
Affects
2022-2024 i4 in BMW service bulletins.
Symptoms
High-voltage warning, charging disabled, no readiness, insulation fault codes.
Typical repair cost
$0 warranty if covered; $3,000-8,000+ out of warranty.
Codes / scan clues
0317F2, 0317F1; SI B12 05 23.
Root cause: Insulation resistance faults can be traced by ISTA to the eDrive motor or related HV components.
Quick check
- Scan CCU and eDrive modules.
- Ask about any HV insulation diagnosis.
- Do not buy with active HV warning.
- Check whether the fault appears after wet weather or charging.
Buyer note
Insulation faults are high-voltage specialist work. They are not normal software glitches.
Owner note
Stop using DC fast charging until BMW diagnoses an active insulation fault.
