All Known Issues

Adaptive air suspension is standard equipment and the biggest 7 Series claim category

SeriousSuspension & Chassis

The i7 rides on standard adaptive air suspension that can raise the nose by 20mm for steep drives and XXL speed bumps and lowers at motorway speed, with an optional active anti-roll system. That is also the region where 7 Series warranty money goes: suspension accounts for 33.9 per cent of claims on the nameplate with an average repair of £1,027, the largest single category by a wide margin. For a UK buyer the practical risks are perished air springs, failed height sensors, a compressor working too hard and salt-driven corrosion of the mountings around our wheel arches.

Est. Repair Cost: £600-£2,200 per corner for air spring or damper replacement
Warning Signs:

Car sits low on one corner after standing overnight, Suspension warning message or the system refusing to raise for a driveway, Compressor cycling repeatedly, or running when the car is parked, Harshness over speed cushions compared with the rest of the model

What to Inspect:
  • Cycle the suspension through every height mode on the viewing and listen for compressor labelling or hesitation
  • Ask for the height readings from a diagnostic tool and check the car sits level
  • Inspect the air spring bellows for cracking and the surroundings for winter salt corrosion
  • Confirm whether any suspension work is covered by remaining factory or certified warranty

Windscreen wiper arm recall on early i7 xDrive cars

ModerateBodywork & Rust

Recall R/2023/288 (9 October 2023) covers 100 UK i7 xDrive vehicles built between 14 October 2022 and 26 January 2023. Under certain conditions, extra loading on the wiper arm can cause loss of wiper movement; the dealer inspects the mechanism and replaces it if necessary. On a car whose driver assistance and visibility systems are networked, a wiper that stops mid-journey in British rain is both a safety and an MOT problem, and the small population means many used examples simply have no record of the work.

Est. Repair Cost: £0 under recall; £400-£900 for a wiper motor and linkage
Warning Signs:

Wipers that stall, slow down or stop in the middle of a sweep, Grinding or clicking from the scuttle when the wipers run, Wiper blades sitting in the wrong parked position, A warning message for the wiper system or rain-sensing wipers not activating

What to Inspect:
  • Check the build date against the 14 October 2022 to 26 January 2023 window and confirm R/2023/288 with a BMW dealer by VIN
  • Run the wipers on a dry screen, listen for binding and confirm they park straight
  • Test the rain sensor by spraying water on the screen while driving off
  • Inspect the scuttle grille for debris that can jam the linkage and burn out the motor

Software issues in the infotainment and driver assistance systems

ModerateElectrics & Electronics

Parkers' verdict on i7 reliability is that it is too early to comment on a relatively new electric platform but buyers should keep an eye out for software issues in the sophisticated infotainment system. Warranty data for the wider 7 Series family backs that up: electrical faults account for 16.5 per cent of claims with an average bill of £397, and carwow notes that BMW's overall reliability rating is improving but still trails Lexus. In practice that means screen reboots, dropped phone pairing, camera or assistance warnings and dealer software campaigns rather than broken parts, which are cheap individually and irritating in aggregate.

Est. Repair Cost: £0-£600 for diagnostics, module replacement or wiring
Warning Signs:

Curved display freezing, blanking or rebooting with no pattern, Reversing camera or 360-degree view slow or absent, Driver assistance features greyed out with a sensor or calibration warning, Charging or remote app functions that fail until the car is restarted

What to Inspect:
  • Ask for the current software level and whether all BMW service campaigns affecting the VIN have been applied
  • Test camera, sensors, phone pairing, wireless charging and voice control on a cold start
  • Check the 12V battery health, since low 12V voltage on EVs produces phantom electrical faults
  • Have an independent specialist read stored fault codes rather than accepting a cleared light

Buying Tips for 2023 BMW i7 (G70)

  • Confirm the eight-year, 100,000-mile battery warranty has been registered and transferable, and get the pack state-of-health figure in writing.
  • Check R/2023/288 (wiper mechanism) is closed if the car was built between October 2022 and January 2023.
  • Budget for adaptive air suspension work; 33.9 per cent of 7 Series warranty claims are suspension-related at an average of £1,027.
  • Test every software-driven function cold: rear cinema screen, four-wheel steering modes, remote parking assist, over-the-air update history.
  • Inspect the tyres and rims hard - large-diameter wheels on a heavy car mean kerb damage and one-way tyre replacement bills of over £1,200.
