2007 Jeep Grand Cherokee Laredo 4dr SUV (3.7L 6cyl 5A)
Bought my Cherokee brand new in 2006, immediately began having problems... the same as most complaints on here. My jeep would lose power, fail to accelerate over 30mph, fail to start, check engine light goes on & off, all dash lights come on & off.
This began before 30,000 miles so the dealer replaced the ignition switch under warranty, that worked great for 20k+ miles but the problem began again recently.
PLEASE report your issues to the National Highway Traffic Safety Administration. 100's if not 1,000s of people are complaining of this problem online and Chrysler needs to be held responsible for it.
