The total number of Park Outside recalls jumped nearly 50% in the last week, to more than 3.2 million vehicles nationwide, according to new analysis by vehicle history provider CARFAX.

The increase comes after Stellantis issued a major safety recall affecting more than 1 million vehicles due to concerns that they could unexpectedly catch fire.

Stellantis, the parent company of Chrysler and other brands, said the recalled vehicles, primarily affecting model-year 2021-2025 Jeep Wrangler SUVs and Gladiator pickup trucks, face a potential fire risk.

Stellantis tells CARFAX that the Jeeps “may have an electrical connection issue in the electric hydraulic power steering pump wiring. In rare circumstances, this may cause combustible materials to overheat, potentially leading to a vehicle fire.”

A “Park Outside” recall is issued when automakers and federal safety regulators determine a vehicle could catch fire even when it is turned off and unattended. Owners are advised to park those vehicles outdoors away from homes, garages, and other structures until the recall repair is completed.

“An unrepaired Park Outside recall doesn’t just put a vehicle at risk; it can threaten garages, homes, and anything parked nearby,” said Faisal Hasan, vice president of Data Acquisition at CARFAX. “Although we never want to see a jump in these serious recalls, the good news is recall repairs are free.”

Stellantis added in a statement that “affected customers will be notified” and that they anticipate “a solution no later than July.”

The top 10 states with the most vehicles under Park Outside recalls are:

1. Texas: 302,000

2. California: 300,000

3. Florida: 279,000

4. Ohio: 138,000
