BMW is recalling around 30,000 plug-in hybrid vehicles (PHEVs) in the United States over a fire risk. The recall affects certain 3, 5, and 7 Series PHEVs from model years 2016 to 2020. Despite concerns about hybrid batteries in general, the issue is linked to the combustion engine starter motor, not the high-voltage battery.
What’s Causing the Recall?
BMW has identified a fault in the starter motor used in some PHEVs. Water can enter the starter’s electrical relay, causing corrosion over time. This corrosion might disrupt the electrical connections needed to start the engine.
The problem could also lead to a short circuit and overheating in the starter motor. In rare cases, this overheating can cause a fire, either while driving or when the vehicle is parked with the ignition off.
Which Models Are Affected?
- 2016-2018 BMW 330e
- 2018-2020 BMW 530e
- 2017-2019 BMW 740Le
BMW will replace the faulty starter motors at no cost. Owners who already replaced the starter themselves will be reimbursed.
Background and Safety Precautions
BMW’s recall follows an earlier 2025 campaign for non-PHEV vehicles with a similar issue affecting about 200,000 cars. The PHEV models had been checked previously but were reevaluated after new data and field reports involving a few incidents.
BMW advises owners to park recalled vehicles outdoors until the repair is done as a safety measure against potential fire risk. So far, no accidents or injuries have been reported related to this issue.
Why This Matters
This recall highlights that not all hybrid or electric vehicle fire risks originate from batteries. Components used in the combustion engine system can still pose safety concerns. For plug-in hybrid owners, BMW’s proactive approach to replacing faulty parts free of charge aims to maintain safety and confidence in their PHEV lineup.
