Some 2008-09 9-7X models with 4.2L engines may emit a ticking sound from the engine compartment. When you open the hood take a close look at the exhaust manifold, reports Saab, because there's a good chance there's a crack in it. The crack is what causes the ticking noise. Installing a revised manifold with a stress-relieving slot machined between the two center runners, part No. 12637060, will eliminate the noise.
Drivers of 2005-06 Focus models with MTX-75 manual transmissions may complain that it's difficult or impossible to put the car into gear. Ford says the problem typically affects vehicles built between 4/6/05 and 8/16/05, and is due to the gearshift cable detaching from the transaxle. Installing a revised cable with an updated retention system, part No. 3S4Z-7E395-GB, should eliminate the shifting troubles.
Some 2009-10 Chrysler 300s and Dodge Magnum, Charger and Challenger models with 5.7L engines may produce a hiss or groan from the power steering system when performing low-speed turns.
According to Chrysler, the noise usually affects vehicles built before 1/21/10, and is due to a poorly designed power steering return hose. Installing an updated hose with better flow characteristics (part No. 68067353AB for vehicles with an external power steering cooler; part No. 68044363AA for vehicles without a cooler) should eliminate the noise. If it doesn't, Chrysler says you'll have to replace the steering gear, as well.
