What owners say

Engine failed, speedometer, tach went to 0, all gauges went to 0, power steering failed after I declutched and then coasted to a full stop (power brakes failed but still had some brake input) safely on the shoulder of an off ramp. (This not the first time this has happened, however it was the first time pulling a full trailer, so I drive as if it could happen again) Vehicle was at Branhaven Jeep in Branford, CT last July @ 64429 miles... they were unable to duplicate. It is now at Gengras Jeep in East Hartford, CT, same story. I've asked Gengras to replace the ignition switch again. I have the ignition switch from Branhaven which I found the copper plate worn off to steel and evidence of arcing on the contacts

The oil pump drive assembly (opda) upper bushing has no way to lubricate due to manufacturing error in the 2005 and 2006 4.0 engine. This causes high metal to metal scraping sound and will result in engine failure. Happened after 38000 miles in a well maintained vehicle. Talked to many jeep dealers and service tech's and they refuse to give any assistance or suggestions for a fix.

2005 jeep wrangler. Well maintained. Highest quality oil, spark plugs, air filters, cooling system. Camshaft failure at roughly 50,000 miles. Excessive wear causing knocking. Diagnosis from chrysler: new engine required. No overheating, no abuse. The oil pump drive assembly gears are worn down so oil is not flowing properly. This is a possible cause for the camshaft failure. The other possible cause for the camshaft failure is that it is a flat tappet camshaft from the factory. This specific type of camshaft needs the zddp oil additive. Modern oil does not contain zddp because it causes catalytic converter failure. Without zddp excessive wear occurs. This is covered in sae bulletin # 770087. Sae is the society of automotive engineers. Once wear reaches a certain level further wear is rapid and causes catastrophic engine failure.furthermore, my jeep is still under powertrain warranty. However, my warranty has been unlawfully denied because I have some unrelated aftermarket parts on my jeep. Litigation is pending on this issue. Chrysler has gone against their own written warranty, and well as federal law (magnuson-moss warranty act).

Chrysler changed the oil pump drive assembly (opda) on 2005-06 model jeep wranglers. The opda was designed with a seal preventing oil from lubricating the upper bushing causing premature failures. These failures will result in a immediate drop in oil pressure causing the potential for complete engine failure at highway speeds. This will result in severe engine damage and may result in property and/or bodily injury. Chrysler issued a tsb (e05r) on certain models, however this has become a larger issue.

2005 jeep wrangler (tj in canada). Check gauges light came on while driving on highway. Drove to get off at exit. Car stalled and would not restart. Towed to dealership. Gears on oil pump were stripped and no oil got to engine -as a result engine seized. Apparently there was a service bulletin but it seems that the serial # on my oil pump is not within the range of the bulletin. At 138,000 km I have to replace an engine (outside of warranty).
