Had oil changed by dealership and began to smell a burned oil smell. Thought maybe oil dripped on engine during oil change. Then noticed small oil puddle under Jeep in parking spot and oil on underside of Jeep. Took in for service and dealer stated saw oil but no idea where it's coming from, washed down engine told to watch for oil. Oil leak continues to worsen and call for appointment which is 2 weeks out because loaner is needed. Oil down 1/2 quart from leaking. Come home tonight and large oil puddle under Jeep. Lift hood and take off engine cover and a large pool of oil on top of engine right next to oil filter housing. Do some research on web and it appears that cracked oil filter housings are an issue on the 2014 Wrangler. Call dealership and they are unable to move up appointment because no loaners are available. Tell me to keep driving and just topping off oil every day even tho my new Wrangler is now covered in motor oil on the whole underside. Here are pics of the issue and information on the problem. www.wranglerforum.com/F274/2014-cracked-oil-cooler-housings-looks-like-A-serious-issue-698297-4.html.

Oil noted dripping from the transmission case seam onto the exhaust crossover pipe. Probably did not catch fire due to the cold (11F) winter temperatures. Oil leak was found to be caused by defective rear main seal. Previous oil change (the first one for this vehicle) performed professionally. Oil replenished was "5.90 quarts" in a nominal 6 quart system. Vehicle: 2014 Jeep Wrangler unlimited jku, 3.6L "pentastar" engine, 6 speed manual transmission.

Wrangler 6-cyl

  • 1,500 miles
Stopped at a traffic light when noticing a light gray smoke around the vehicle. Continued from the stop light when the smoke started to get more darker and black. Realized the smoke was coming from the vehicle and I drove to side of the road. Open the driver side of the vehicle and smoke were coming from the front of the vehicle and from under the vehicle. I then turned the ignition key off and exit the vehicle. When getting across the road from the vehicle I turned and saw fire coming from the vehicle. This statement was made by the driver of the vehicle (the wife of the owner of the vehicle).

Wrangler 6-cyl

  • 2,900 miles
Transition & engine coolant temp immediately rose to alarm status (300 degrees) in first ever light duty 4 wd application. Off road 4WD conditions and terrain consisted of a 5% grade in low cut hay field. Alarm indicated immediate corrective action was necessary. Vehicle temperature gauges were rising from normal tolerances to alarm status in two minutes. Corrective action included cutting engine to cool. Corrective action also required blower and heater on highest settings to cool block and maintain operable driving condition temperatures. Engaging in the slightest load while 4 wheel drive train was engaged (off road) immediately replicated severe overheating condition of both tranny and block coolant. Vehicle was operable at normal operating temperatures at high speeds in two wheel drive while on pavement only. Vehicle is a 2014 Jeep sahara unlimited Wrangler with "V" 6 cyl motor automatic transmission with 2,900 miles on odometer (vehicle is brand new purchased in March 2014 - date of this report is April 2014).

Wrangler 4WD 6-cyl

  • 3,800 miles
In January 2014 I purchased a brand new 2014 Jeep Wrangler at river oaks Chrysler Jeep in houston, tx and around March 1st I noticed oil leaking from my vehicle. I was unsure it was my vehicle because I assumed it was a new vehicle that there is not way it could be my Jeep. On March 5th 2014 I had a lot of oil spill out of my vehicle. I took the Jeep into the dealership on March 6th and they noticed the spilling of oil. I dropped of my Jeep with them and they said they fixed it. They said that my oil cooler was leaking. And they replaced the oil cooler. Come to find out this is a major fire hazard. A brand new car and the oil cooler fails. They were really vague as to why this happened and brushed me off telling me "its fixed, don't worry about it". I don't feel comfortable now driving my Jeep and I am concerned if this is a lemon car. I spoke to several managers over at river oaks Chrysler Jeep and they seemed to brush me off and would tell me "you are getting mad over a car; one of our sales just found out he has cancer". this was very unfair and I am not happy with what I purchased. Please help.....updated 08/20/15
