The BMW i3 Battery Warranty: The Facts

Investing in an electric vehicle (EV) like the BMW i3 is not just a leap into sustainable mobility but also a commitment to cutting-edge technology. One crucial aspect of ownership is understanding and maximizing the benefits of the BMW i3 Battery Warranty.

In this comprehensive guide, we’ll delve into the details, answering common questions and providing insights to ensure you make the most of your BMW i3 ownership experience.

Understanding the BMW i3 Battery Warranty

The BMW i3 Battery Warranty is designed to safeguard against failures in the high voltage battery resulting from manufacturing defects.

This warranty is an integral part of the broader BMW i Warranty package, offering an additional layer of protection specific to the heart of your electric vehicle—the battery.

Warranty Duration

Your peace of mind is extended for an impressive duration with the BMW i3 Battery Warranty. It covers the high voltage battery for up to 8 years from the date of first registration or until it reaches 100,000 miles, whichever milestone occurs first.

This extended coverage speaks to BMW’s confidence in the durability and performance of their electric vehicle technology.

Authorized Service Workshops

To make the most of your BMW i3 Battery Warranty, it’s imperative to entrust any high voltage battery repairs to a BMW i Service Authorized Workshop. These specialized facilities are equipped with the expertise and resources to ensure that your BMW i3 receives the care it deserves.


The benefits of the BMW i3 Battery Warranty are not confined to the original owner. They are fully transferable to subsequent owners, provided the transfer is facilitated by someone other than an approved BMW i Service Authorized Workshop.

This transferability adds significant value if you decide to part ways with your BMW i3, making it an attractive proposition for prospective buyers.

These inspections are crucial for identifying any potential issues early on and addressing them promptly.

Authorized Repairs and Replacements: In the unfortunate event that your high voltage battery requires attention, it is essential to have repairs or replacements carried out exclusively by a BMW i Service Authorized Workshop.

Common Exclusions from Warranty Claims

While the BMW i3 Battery Warranty provides extensive coverage, there are specific scenarios and conditions where claims may not be accepted. Understanding these exclusions is vital to prevent any unintended lapses in coverage.

1. Non-Homologated Conditions: Operating your BMW i3 in a country with regulations different from its original homologation may void the warranty.

2. Abnormal or Overstressed Operation: Competitive motor sports events or any abnormal, overstressed operation outside of normal driving conditions may not be covered.

3. Unauthorized Modifications: Installing parts not approved by the manufacturer or manipulating the BMW i3 or its parts, including software, without approval can lead to warranty exclusions.

4. Failure to Follow Instructions: Not adhering to the instructions outlined in the owner’s manual regarding the use, maintenance, and care of the BMW i3 may impact warranty claims.

5. Unauthorized Battery Handling: Opening or removing the high voltage battery by someone other than an approved BMW i Service Authorized Workshop can void the warranty.

Debunking Common Misconceptions

To address some common misconceptions, it’s essential to highlight the key points:

Confusion on Mileage Limit: Some owners may encounter conflicting information regarding the mileage limit for the warranty. The correct figure is 100,000 miles, offering ample coverage for the battery’s lifespan.

Variations for REX Models: Range Extender (REX) models have a different warranty structure, with variations depending on the state. However, for the i3 BEV, the 8-year/100,000-mile warranty remains consistent across the board.

In-Service Date vs. Production Date: The warranty clock starts ticking from the in-service date, which is the day the vehicle is delivered to the customer. This is a crucial distinction, as it accounts for the time the vehicle spends on the dealer’s lot, potentially benefiting the owner.

Costs and Considerations

While the warranty offers substantial coverage, it’s worth noting that certain diagnostic tests, such as the $400 inspection for warranty claim eligibility, may come with a cost.

However, this investment can be a prudent step in determining the health of your high voltage battery and whether it falls under the warranty coverage.


Owning a BMW i3 comes with the assurance of cutting-edge technology and a commitment to sustainable driving. Understanding and maximizing the benefits of the BMW i3 Battery Warranty is a crucial aspect of this ownership experience.

By adhering to the recommended service intervals, entrusting your BMW i3 to authorized workshops, and being aware of warranty exclusions, you can enjoy peace of mind and uninterrupted electric driving.

The BMW i3 Battery Warranty is not just a warranty; it’s a pledge to support your electric journey for years to come
