Six problems related to car stall have been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
The Jeep stalls intermittently. It has been in the shop several times for this problem, but it still continues. Last week my son was driving home, and after 2 hours of driving, the vehicle stalled at 70mph in the middle lane of a major highway. It is now back in the shop, again! it is not safe to drive.
2012 Jeep Wrangler sport 3. 6l vehicle does not start at random. Vehicle has stalled at highway speeds. All electrical will turn on but Jeep will not crank over or make any attempt to start. Wipers turn on, on their own. Battery, and starter have both been checked. Evidence leads to faulty tipm sensor but because the Chrysler dealership can not duplicate the error after 5 tries they said they can not replace the tipm. Dealership states they can not just throw parts at it to fix the issue even with hundreds to thousands of other Chrysler products having the same issue.
Was informed in Dec 2013 by Chrysler that my 2012 Jeep was in need of safety recall n28/NHTSA 13v-234. Have been waiting 3 months so far for part oil cooler tube and no known date when I can get one installed. Dealer says they can only order one of these every 14 days. . . Chrysler customer service says they can order 7 every 14 days to avoid some dealers hording parts. My vehicle has been deemed unsafe. I need to get this repaired. Who can get Chrysler to release the parts? this is terrible customer service.
Vehicle is currently (Dec 2012) at dealer having heads/valves replaced (10th day after waiting 10 days for parts), original report 9 Nov: idling engine continues to be very rough, much rougher than when reported to dealer on November 9 2012, dealer did pcm reflash/update as stalling maneuver, after which problem worsened and mil came on vehicle is vibrating abnormally when stopped and idling, all passengers feel the car shaking, almost stalls at times idling engine changes speeds and sound intermittently and is running very loud engine always had slight ticking on left side since new but was never loud or rough loss of power felt at acceleration at top of gears (manual) white exhaust emissions after cold start, this never happened before engine light mil is on and off repeatedly - reads p0306 cylinder 6 misfire gas mileage severely affected (approx 25% worse), car now has 18k miles; dealer said it was ok to drive it - however driving it may cause other damage this is 3rd visit to dealer - when problem first reported dealer service dept said I might have put water in the gas. I have had to push the dealer to fix this and the general attitude has been adversarial and not helpful.
I have had at least 100 times where my Jeep has stalled and just stopped running. It has happend when I have slowed down, and has stopped in intersections. It has stopped when starting from a stop etc. I have had numerous manual transmission cars and this has never happened. It scares me , and makes me fear for my life. I have changed the way I drive because of it, with the fear of worrying my Jeep will just stop running , when I pull out into traffic. I have had the switches in the car not work, and function erratically. Lights stay on, when turned off, after turning them off numerous times, they finally go out. I have had my breaks respond oddly, and get weak. I have had the heater not come on, then turn switch again and it works. Have had defrost some on when defrost was off. Numerous electrical functions, malfunction. I don't bother with Jeep, as my mileage is over 36,000- no more warranty, but these things began, about a month or two into Jeep ownership. These problems used to be infrequent, but now this power failure happens often. Some days it happens 4-5 times. Please help me with this matter, I do not want to be injured or killed, due to this problem. I also do not want my family or someone elses hurt ,becuase of it either. I started doing research about these issues and find I am not the only one, it is common. I also have a whistle in the brake line, vaccuum I think??? it causes the breaks to not be strong at times. I have had my brakes completely replaced and this condition persists, it also seems many with my model of Jeep experience this as well. All of the hinges on the doors are rusting from the inside out, as well, I see the paint bubbling up .
Really have 3 issues with this vehicle. The first is that the engine began to tick noticeably at around 5000 miles, sound definitely coming from #2 cylinder. Was initially told not to worry, noise was normal, oddly it did not tick previously. The short story is that it set a p0302 code at around 12,000 miles. Chrysler did not authorize a rental and the dealer was less than cordial. They put the thing back together and damaged an emissions valve, so more delay. Get the vehicle back, ran silent for 2,000 miles, the tick is back. Now at 19,000, no code yet, but I fear its coming. Problem #2, exhaust smell, get it nearly all the time, especially under load, no resolution yet. Problem #3, wet carpet on drivers side, no resolution yet. Oh, I forgot to mention, there is a fourth, I have just installed the third windshield in less than 6 months. Its not the quality of the glass, its the steep angle of the windshield, but that's what you get when you buy a Wrangler. I have been loyal to us brands, this is our 32nd new vehicle, won't by a Wrangler again.
