The "Check Engine Light" came on. The "Check Engine Light" came on and started to flash on and off. Jeep was towed to the dealer. Dealer ran the diagnostic and 3 hours later told me that the heads had to be replaced. Seems a piston was miss-firing. They kept the Jeep for 2 weeks to complete the repair. Seems all the 3.7 Litre heads up to a certain year are defective and they are fixed/replaced as they come in. Not a recall item item as it is not a safety issue/problem. Item repaired under warranty. Total cost = $5K. Told at the time of the repair that Jeep has fixed the defective head and problem will not re-occur. Its been 6 months and almost 5,000 km later and so far so good.
Does the rear differential require synthetic oil? I've been told that Liberty's with the tow package (which is what I have) require it.
Would you buy another car from this manufacturer? Don't Know
