While the recent success of the Wrangler Unlimited bodes well for Jeep and its continued domination of all things off-road, NHTSA is in the midst of investigating a series of complaints claiming that the iconic Jeep is stalling at highway speeds, and in some cases, losing electrical power.

All Wrangler models are under the agency’s watchful eye, both the two- and four-door models, regardless if they’re equipped with four-wheel drive or the standard two-wheel drive. NHTSA says that only 53 complaints have been filed, with 12 reporting a loss of lighting and electrical power.

NHTSA’s investigation will include approximately 35,000 vehicles total, and at this point, no crashes or fatalities have been attributed to the issue.
