Engineering a vehicle to handle 707 horsepower can be no easy feat. Just keeping it supplied with a constant and generous stream of fuel, we’d imagine, would prove a challenge in and of itself. And it seems that challenge may have been a little too great for at least one of the suppliers chosen to help build the new Jeep Grand Cherokee Trackhawk.

According to the National Highway Traffic Safety Administration, the fuel lines on the JGC Trackhawk could detach. That would not only starve the 6.2-liter supercharged V8 engine of fuel, but could potentially start a fire.

As a result, FCA is recalling 1,242 of the muscle-utes in the United States to inspect and repair those fuel lines. The vehicles in question are thought to have been built between October 10 (when production began) and December 10 (when the supplier initiated a new quality-control process). “Lesser” versions of the Grand Cherokee are not affected because their (relatively less taxed) fuel lines, though furnished by the same supplier (Martinrea International), are made on a separate production line.

The recall process is set to begin March 2. In the meantime, the manufacturer has issued a stop-sale order for those examples still sitting on dealer lots.

The Grand Cherokee is the third model under the Fiat Chrysler umbrella to be fitted with the Hellcat engine – following the Dodge Charger sedan and Challenger coupe. The engine is based on the 6.4-liter Hemi V8, but destroked slightly to fit a longer camshaft, and fitted with a supercharger to produce 707 horsepower and 645 pound-feet of torque.

Though the Charger and Challenger are both offered with all-wheel drive in lower specs, the Jeep is the only version that marries the Hellcat engine to four-wheel traction. The combination helps it to accelerate from 0-60 in 3.5 seconds, run the quarter-mile in 11.6, and top out at 180 miles per hour.
