Maintenance & Warranty
Recommended Bmw X7 Service Intervals
Condition-Based Service (CBS) tells you exactly when service is due. Transmission fluid was labeled 'lifetime' but many owners service at 60K-100K.
"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
Bmw New-Vehicle Warranty Coverage
Corrosion is unlimited miles for 12 years
These are the terms for a new Bmw. If you're buying a used 2021 X7, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Bmw dealer for VIN-specific remaining warranty.
