2010 Jeep Grand Cherokee Laredo 4dr SUV (3.7L 6cyl 5A)
Purchased my JGC used w/28,000 miles on it. A couple days later engine light comes on. Dealer replace 02 sensor and on the way home it goes on again. It's been in the shop going on day #3 and now they say computer is shot. I dont think they no whats wrong with it. I'm starting to think this was a bad purchase. At least it looks good.
Interesting. We bought a used 2010 Cherokee Laredo with the 6 cylinder like yours and the engine light is giving us fits too. Started searching the web and found conflicting remedies, as if the car had been produced by four different manufacturers. Dealers seem to be waffling on what to do. One even blamed the EZPass windshield stickers. The electronics for this year are beginning to look defective. Maybe a recall is warranted. Hope yours was finally repaired. Others on this site seem to report fewer problems than forums on other sites.
