BMW I8 warranty claim denied?

181 manufacturer communications on file 4 warranty extensions / campaigns 2014–2020 model years covered

If BMW recently denied your i8's warranty claim, you're not alone, and the denial may not be the final word. Across the 2014–2020 BMW i8, manufacturer records filed with NHTSA show 181 documented communications, including 4 formal warranty extensions or service campaigns covering issues like High-Voltage Battery Assembly temperature sensors, the EVAP system, and a 10-year/120,000-mile extension for the fuel tank pressure sensor. These filings show that BMW has acknowledged specific defects in this model's components, which can be relevant when a dealer denies coverage for a related repair.

Dealership denials sometimes happen before all applicable extended warranties, service campaigns, or documented defect patterns are considered. When a claim references a part tied to one of these filings, there may be grounds to request a second review using the manufacturer's own documentation.

ClaimRight offers a free assessment of your denial. We review your paperwork against the manufacturer's filed communications and outline what options may be available to you. There's no obligation, and our goal is simply to help you understand whether your situation matches documented, acknowledged issues for your vehicle.

Common questions

Can a denied BMW i8 warranty claim be reconsidered?
Yes, denials are sometimes reversible, particularly when the repair relates to a component covered by a documented warranty extension or service campaign. BMW has filed 4 such extensions for the i8 with NHTSA, covering parts like the HV battery temperature sensors and fuel tank pressure sensor. Reviewing your denial against these filings can clarify whether your situation may qualify for further consideration.
What is the BMW i8 fuel tank pressure sensor warranty extension?
In 2018, BMW extended the limited warranty for the fuel tank pressure sensor on eligible i8, X5 PHEV, and i3 REX vehicles to 10 years or 120,000 miles, whichever comes first. If your denied claim involved this component, it may be worth confirming whether your vehicle falls within the eligible extension period before accepting the denial as final.
Why did BMW extend warranty coverage on the i8's High-Voltage battery sensors?
BMW filed warranty extensions in late 2024 specifically addressing defects in materials or workmanship for the HV Battery Assembly's cell module temperature sensors on eligible vehicles. These filings indicate the manufacturer acknowledged a recurring issue with this component, which may be relevant if your denied claim involved battery diagnostics or related sensor repairs.
