BMW 750e G70 Reliability - Problems & Costs

BMW's flagship plug-in hybrid sedan, combining the smooth B58 inline-six with an electric motor for 490 hp and roughly 80-90 km of electric-only range. Sold alongside the all-electric i7 in the G70 generation. Still new on the market, so long-term reliability data is limited, and the active integrated brake module recall affecting 2023-2024 cars is a key verification point.· more· less

Refined B58 inline-6 powertrain Efficient PHEV in urban use

Active brake module recall pending Limited long-term reliability data

Buy if: You want a refined flagship with electric commuting capability and have verified all recall work is complete.

Avoid if: You plan to keep the car beyond the 8-year battery warranty or cannot tolerate dealer-only diagnostics on complex hybrid systems.

Common Problems

Integrated brake control module failure (recall)

€0 - 2,5001 of 6

Servomotor welds may break, causing loss of power brake assist - active 2024 recall · more· less

A 2024 recall affects 2023-2024 750e xDrive (alongside many other BMW models) where welds in the servomotor of the integrated brake control module may break, causing loss of power brake assist and rear brake function, with ABS and DSC potentially inoperative. BMW dealers replace the module free of charge under recall. Critical to verify with VIN that recall work has been completed before purchase. If the module fails outside recall coverage, replacement runs €1,800-2,500.

Hybrid charging electronics fault codes

€200 - 1,2002 of 6

Erroneous fault codes trigger malfunction indicator lamp despite AC charging working normally · more· less

Some 750e PHEVs trigger the malfunction indicator lamp with erroneous fault codes related to AC charging electronics, despite charging operating as designed. BMW has issued software updates via TSBs to address this. Typically resolved with a software flash at the dealer (€200-400). If a hardware fault is found in the charging electronics, costs can climb to €1,200 for module replacement.

iDrive 8 freezing and software glitches

€100 - 8003 of 6

Curved display freezes, GPS drift with phone projection, intermittent system crashes · more· less

iDrive 8 with the curved display has well-documented teething issues including system freezes, delayed responses, GPS drift when smartphone projection is active, and occasional unresponsive controls. Most issues resolve with software updates pushed over-the-air or via dealer reflash. Soft reset (holding volume knob 25-70 seconds) addresses most freeze events. Hardware replacement of the display unit is rare but expensive if needed outside warranty.

Air suspension level sensor and compressor wear

€600 - 2,2004 of 6

Two-axle air suspension is complex and historically a weak point on luxury BMWs · more· less

The 750e uses two-axle air suspension as standard. While too early for widespread G70 failure data, the system shares architecture with other BMW models that have known level sensor and compressor issues at 80,000-120,000 km. Sensor replacement runs €400-600 per unit; compressor replacement €1,200-1,800. Air spring failure (bag perforation) costs €700-1,000 per corner. Check for uneven ride height after the car has been parked overnight.

Steering spindle defect (recall)

€0 - 1,5005 of 6

Steering spindle may break on certain 2024-2025 cars - recall remedy available · more· less

Certain 2024-2025 750e xDrive vehicles have a defect where the steering spindle may break, requiring greater steering effort to control the vehicle. BMW addresses this under recall, free of charge. Verify with the VIN that recall work has been completed before purchase. If outside recall coverage, repair costs vary widely depending on damage.

12V auxiliary battery drain

€300 - 6006 of 6

Complex electronics and standby loads drain 12V battery on cars used infrequently · more· less

Heavy electronics load on modern PHEVs (always-on connectivity, soft-close doors, comfort access, gesture controls) drains the 12V auxiliary battery if the car sits unused for 1-2 weeks. Not a defect, but a characteristic of the vehicle class. Battery replacement at BMW dealer costs €400-600 including registration to the BMS. Keeping the car on a trickle charger when stored prevents this.

Too new for clear long-term verdict, but recall verification is essential

The 750e G70 is BMW's newest flagship PHEV with limited long-term ownership data. The active integrated brake module recall is the most important purchase check - verify completion via VIN before signing. Hybrid powertrain and iDrive 8 software issues are common but mostly addressable via dealer updates. Most major systems remain under BMW's 2-year factory warranty (3-year extension common) or the 8-year/160,000 km high-voltage battery warranty for the time being.

Pre-Purchase Inspection Checklist

General checks

Service history
Complete BMW dealer or authorized specialist records essential. Verify all recall work has been performed via VIN.
Tires
Check tread depth, age (date codes), and uneven wear patterns. Large 19-21" tires wear faster and are expensive.
Cold start
Must start engine completely cold. Listen for unusual noises and verify smooth transition between EV and ICE modes.
Test drive
Minimum 30 minutes including highway, urban, and hybrid mode transitions. Verify all electronic systems.

Specific for this vehicle

Verify integrated brake module recall completed
2023-2024 cars affected. Critical safety recall - confirm completion with BMW using VIN before purchase.
Verify steering spindle recall (2024-2025) completed
Contact BMW with VIN to confirm recall remedy has been applied if applicable.
Test iDrive 8 system thoroughly
Test all menus, GPS, smartphone projection, voice control. Check for laggy responses or freezes.

+ 4 more checksShow less

Check air suspension function
Verify all four corners level after overnight parking. Listen for compressor noise on startup.
Test EV-only mode and battery range
Charge fully and verify electric-only range. New cars should achieve 70-85 km depending on conditions.
Inspect 360 camera operation
All 4 cameras should display clearly. Moisture/freezing complaints reported on 7 Series cameras.
Verify hands-on detection works correctly
2023-2024 cars: ground connection issue could cause inoperative system. Test with both hands on wheel.

Recalls and Technical Service Bulletins

Integrated brake control module servomotor (2023-2024) Critical - verify completed

Steering spindle defect (2024-2025) Verify completed

Hands-on detection ground connection (2023-2024) Verify completed

AC wiring harness damage during cabin filter replacement (2024-2025) Verify completed

Contact BMW with the VIN to verify all recalls have been completed. The integrated brake module recall is particularly important and should be addressed before driving the vehicle.

Warranty Status

Factory warranty (2 years + 1 extension) May still be active on 2023-2024 cars

High-voltage battery warranty 8 years / 160,000 km from registration

Rust perforation warranty 12 years
