Four problems related to engine burning oil have been reported for the 2013 Jeep Wrangler. The most recently reported issues are listed below.
My Jeep started smoking smelt a badd oil burning smell and almost caught on fire when I finally got stopped looked under the hood and I could see oil floating on top of the engine everywhere and going all down the back of the transmission looks like a part or something may have a crack in it can't really tell oil is all over the under carriage all the way to the rear end has got all over the brakes had troubles and issues with its slowing down without it smelling like an oil fire and smoke pouring out of the brake assembly.
Failure of oil cooler housing, noticed oil burning smell looked under the Jeep and saw oil everywhere.
Oil filter housing, cracked resulting in loss of large amounts of oil, engine has 82,000 miles and oil has been changed every 3000-3500, using manf recommended oil and filter. Started leaking large amount of oil and burning smell, dealer stated that the oil filter housing was cracked due to over tightening of oil filter cap. This is not true, have for the last 4 years used a torque wrench to the manf specifications printed on the oil filter cap. Reviewing this on the internet and sees to be a common problem on the penstar engine which changed from bottom mount to top mount oil filter. Many others have had the replacement covered under the 100,000 mile warranty but this local dealership states it was user error and refuses to cover. Would like for NHTSA to review the number of issues other Jeeps have had with this part breaking, as dealer warned this is a potential fire hazard with the oil leaking.
The vehicle is consuming an excessive amount of oil (more than a quart per 250 miles) and is overheating when under load on long climbs. Overheating and/or excessive oil consumption causes the vehicle to go into "limp" mode which is a sudden and complete loss of power where the engine will not go over 3000 rpm. When oil level drops to about 3 quarts low, the check engine light comes on and the Jeep goes into limp mode. The dealership has replaced valve tappets, the left camshaft and the left cylinder head under my Chrysler "maxcare" lifetime warranty, but the problem persists. Jeep customer care is now telling me the repair may no longer be covered by my lifetime service contract (reference Jeep customer care case number 32175924). The sudden loss of power when at highway speeds from overheating and/or oil loss is a safety issue.
