Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

problem #4

Grand Cherokee Limited 4.7L V8

  • Manual transmission
  • 130,000 miles


It just really really sucks. The WJ Jeep is ruin my opinion the best looking thing the Chrysler-Daimler Corp ever sold. we always kept here serviced with fresh oil, tranny fluid, differential fluid... etc. In total this card has had up to 3 pvc valves, a crankshaft and a cam sensor, oil pan and header gasket seals, a lot of O2 sensors which still has not been fixed, an O2 sensor harness, a lot of o]O2 fuses, a hose here and there, 2 differential lubes, belts, A/C, windows, rear tail lights, heated seats. Most of these problems would occur, we'd get it fixed (out of pocket) and then it would need fixing again soon after. I would love for Chyrsler-Daimler to take responsibility and just send me the parts I need to make this car work well. She runs, but is getting about 10 mpg. I just want my Jeep to not need service beyond standard lubrication and tune ups.

Grand Cherokee Laredo 4.0L

  • Automatic transmission
  • 96,000 miles

This is a well know problem, piston skirt cracks, and eventually causes complete engine failure. The 4.0 engine was bulletproof until around 2000 or 2001 when changes were made to the piston that caused this problem.

problem #2

Grand Cherokee Limited 4.7L

  • Automatic transmission
  • 120,000 miles

Bought vehicle with bad engine, but didn't know how bad till I pulled it apart. The dodge/jeep 4.7L engine mainly before 04 have a lot of problems with parts of the pistons breaking off and causing engine failure. When I took the engine apart, it had multiple piston failures (probably a catastrophic effect from one failing) and broke off part of the cylinder wall rendering the engine useless. My suggestion is to get a used one and rebuild it or if it's a remade make sure they didn't use stock pistons.

Grand Cherokee

I find it very strange that a car that has done so little mileage loses a piston. Daimler Chrysler has offered to pay for half the labour and half the parts bill I think that they should settle the whole bill
