We own a dodge caravan that has some major engine problems that seem to be common for the 2012-2013 v6 penstar engine. The problem is in the engine head and valves. Our van has collapsed cam lobes due to failing rocker arms. The symptom that revealed this problem was a misfire in the left cylinder head. The symptoms are very similar to the problems noted in tsb no. 09-002-14b including a misfire in the left cylinder head and a loud ticking noise coming from this area. Chrysler has an extended warranty known as x56 that addresses the problem noted in tsb no. 09-002-14b. Unfortunately, their warranty only covers the head replacement (which includes the valves and cams) if the head is cracked. While investigating multiple dodge/chrysler forums I have noted a large number of dodge owners experiencing the same problem that we have. In fact, I have learned that the problem is so pervasive that chrysler has an internal star case bulletin, s1309000016 related to the rocker arms and cam lobe problems. The engine check light came on while we were driving.

Po302 cyl2 misfire code.cylinder head previously replaced under same code. This time camshaft intake and exhaust , 16 arm- value and 24 tappet valve lash had to be replaced. Car only has 82,000 miles on it and has had two major engine repairs required. Condition caused by the roller bearings in the rockers coming apart. Check engine light came on while driving. This repair was $2180.94. My mechanic and I think it is all one related engine problem and should have been covered under the extended warranty.

My engine keeps misfiring all the cylinders and I have changed multiple cylinders. While the vehicle was in motion the lights on the inside illuminated and the vehicle stopped in traffic. The engine light came on and I took it to get the codes read and it said p301, p302, p303, p304. I have got this fixed multiple times because it keeps happening.

Tl* the contact owns a 2012 dodge grand caravan. The contact stated that while driving at 50 MPH that the vehicle misfired and the check engine warning light illuminated. The contact stated he diagnosed that the cylinder failed. The contact was able to locate the extended warranty online on the cylinder covered up to 150,000 miles. The vehicle was taken to the local dealer (adams jeep of maryland inc, 3485 churchville, aberdeen, md, 21001) where it was diagnosed and confirmed that the second cylinder had failed and was included under the extended warranty, also that the cam shaft failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and confirmed the warranty for the second driver cylinder head, however stated that the cam shaft was not covered under warranty, and by coincidence they both failed at the same time, no further assistance was offered. The failure mileage was approximately 112,000. The VIN was unavailable.

My 2012 dodge grand caravan showed a check engine light at 67,000. I checked the code to fnd out p0303 is a engine misfire. Could be ignition, plug, or valve-cylinder compression. I had the engine serviced and the light goes out. The next day the light comes back on. I return the vehicle for service to investigate the check engine light. Further investigation reveals there is a bad compression on cylinder 03. I take the vehicle to dodge and they could have told me up front that the right cylinder head is not covered under the extended warranty from chrysler. They take my car into service and find a leak on cylinder 04 also. They gong to replace the left cylinder head but not the right cylinder head with the same identical problem. I am looking at $3500.00 if I choose to replace the right cylinder head. This extended warranty should cover the defect no matter which cylinder head is defected. My wife loves the car. She wants another one. I told her that because of this issue we would be right back here in 4 years with another 3.6l v6 pentastar engine. I am torn. Do I trade the issue back to dodge and get a 4.0l v6 pentstar. I have almost paid it off. This sux great times flushed down the drain because of a engine defect. I love it but I have leave it. Toyota here I come.
