Wrangler Sport Unlimited

  • Manual transmission
  • 30,216 miles

A D V E R T I S E M E N T S

2011 bought brand new in late 2010. Never abused and always driven conservatively. I've had it almost 7 years, but only put 48,628 kilometers (about 30,392.5 miles ) on it.

The amber "Check Engine" light comes on and the engine is running ruff and underpowered. I pull into the nearest gas bar. Sure enough, as I have read here, the dipstick is not registering any oil. 3 quarts later the oil level is ok, but the engine is still protesting. I get it to the dealer where their diagnostic computer points out a #2 cylinder misfire. They pull the sparkplug and it is fouled with carbon. The service tech looks into the cylinder with a borescope and claims the piston rings have spun and the ring gaps have all aligned, allowing oil to flow into the combustion chamber.

How is this possible? I have driven 4 cyl. cars 200,000 km and 300,000 km, only to replace them when the body is starting to rot away from salt corrosion, but a Jeep engine will not last 50,000 km ? They are asking 4 grand to tear the engine apart to fix the problem because the 5 years on the warranty has run out on an engine that was guaranteed for 100,000 km. Last Chrysler/Jeep I will ever buy since they can't stand behind their products.

Wrangler Sport 3.8L V6

  • Automatic transmission
  • 82,126 miles

I bought my 2011 Jeep Wrangler 3.8L used with 67,000 miles on her in 2015, shortly after purchase change oil light came on. I didn't think too much about it, went to quick lube for change, said she was a quart low. I changed oil 3000 miles later, said she was a quart low again, but they could not see where she was leaking anywhere. Next 3000 miles she was 2 quarts, quick lube suggested a thicker oil may help. Next oil change one quart low, The engine light has since come on and I brought her to my my mechanic. He replied, it's internal in the engine, check to see if recall, because with only 82.000 miles I should not be having these issues. I am a 52 year old woman who does not drive my baby like a 20 year old..... should not be having engine issues.... Fix the problem Chrysler!!! I have been a Jeep Wrangler owner since 1998 and never had a problem with the 4.0!!!

Wrangler V6

  • Automatic transmission
  • 61,000 miles

CarMax of mesa az sold me an 2011 jeep wrangler sport 5 days after I bought it the check engine light came on. I took it back they "say" they checked it and reset the light . another week went by and it came on again. Took it back and CarMax treated me like I didn't know what the f*ck I was talking about. This time they said we replaced the gas cap. That didn't work either. I took it to an dodge deaer in az Earnhardt and they looked at it and said its the evape system...prolly an leak. we can smoke it and test for 300.00. I explained my situation and tried to get CarMax to fix the jeep and went to AAA and they refused to investigate. can you help.

Wrangler Limited V6

  • Automatic transmission
  • 38,000 miles

code p0740 has come up, the car only has under 38k miles

i think the fact that i have under 38k in miles this is clearly a defective expensive repair. i would like corporate to help me with this problem based on the fact that the car is almost new. this hardly seems fair. i will push until i get a resolve here. i have maintenance my card regularly and this is clearly a lemon . i will take to social media and anywhere else i have to to get this fixed by corporate
