How long is the BMW X5 plug-in hybrid battery warranty?

8 years or 80,000 miles, whichever occurs first, on the 2016–2018 X5 xDrive40e and the 2021–2022 X5 xDrive45e; 8 years or 100,000 miles on the 2023 X5 xDrive45e (BMW's 2024 reissue of the 2023 booklet) and the 2024–2026 X5 xDrive50e. There was no plug-in X5 for 2019 or 2020.

Is the X5 plug-in hybrid battery warranty longer in California?

For TZEV-certified cars, BMW's 2021, 2023, 2024 and 2025 booklets cover the high-voltage battery for 10 years or 150,000 miles, whichever occurs first, when the car is registered in California or another listed state. BMW states the California TZEV program does not apply to 2026 plug-in hybrids.

Does BMW guarantee a minimum battery capacity on the X5 plug-in hybrid?

No. The 2026 booklet's coverage for capacity below 70 percent applies to battery electric models, not plug-in hybrids.

Does the X5 plug-in hybrid battery warranty transfer to a second owner?

On 2016–2025 cars, yes: the battery warranty is part of the New Vehicle Limited Warranty, which BMW NA gives to the first retail purchaser and each subsequent purchaser.

When does the X5 plug-in hybrid battery warranty start?

On 2016–2025 cars, on the date of first retail sale or the date the vehicle is first placed into service as a sales demonstrator, Aftersales Mobility Program (AMP) Vehicle or company vehicle, whichever is earlier.

The longer term belongs to the California Emission Control System Limited Warranty TZEV, which covers cars certified to California's Transitional Zero Emission Vehicle standard; BMW states that certain X5 plug-ins of each of these years are.
The certification is shown on the Vehicle Emission Control Information label in the engine compartment, after the word "California".
In 2021, 2023, 2024 and 2025 the 10-year battery term is the stated exception to that warranty's 15 years or 150,000 miles for emission-related parts.

Scope note

US market, model years 2016 through 2026, from the BMW of North America warranty booklet that bmwusa.com serves for each X5 model year; there was no plug-in X5 for 2019 or 2020. Each row rests on the printing named in its footnote, and some of those are later reissues of the year's booklet. The booklet delivered with a specific car is the authority for that car.
