What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 BMW 430I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The contact owns a 2026 BMW 430I. The contact stated that while driving at an undisclosed speed, the vehicle stopped and independently parked. Several warning lights were illuminated. The vehicle was driven to the residence. The failure was persistent. The vehicle was taken to two dealers; however, the failure was not duplicated. The vehicle was taken to a third dealer, where it was diagnosed with a failed engine electrical system, digital motor electronic control unit, and transfer case failure. The contact was informed that the transfer case and basic control unit DME needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 7,819.

Tires & wheels
Reports naming tires, wheels, hubs, or the tire-pressure monitoring system.
From owner reports, verbatim
One year after purchasing this new vehicle, the two rear tires were worn to 4/32nds. The dealer advised they need to be replaced. I am [XXX], with no accelerated starts or hard braking, so after one year and 7,500 miles, the rear tires were up for replacement. The dealer reluctantly did a forced balance, which I paid for and BMW Corporate reimbursed. They did not do anything for toe/camber. I do not know if they were out of spec from the factory for balance, toe/camber/alignment or if the tires were faulty. The dealers' only guidance was to replace. So I went to a Firestone dealer and had the tires replaced 255/35R19 96Y for $200 less than the BMW dealer wanted to sell them.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
