Three problems related to gas recirculation valve (egr valve) have been reported for the 2013 Jeep Wrangler. The most recently reported issues are listed below.
Constant ticking noise coming from the top of the engine. This ticking noise is made from worn out rocker arms/ cam lifters as the camshaft rotates. The bearing material in the lifters is not hardened steel and can degrade. All 3. 6l pentastar engines are affected by these defective rocker arms. If the rocker arms are damaged no code will show. The first sines will be a loss in fuel efficacy. As the camshaft wears down changing the displacement of the cylinders this will start causing misfire and stalling during normal driving/ acceleration. Eventually, ware debris can fall into the cylinder and damage the head. I first took my Jeep to the dealership at 60k miles to diagnose. With no codes showing I was told everything in the engine checked out and the ticking noise was from the valves. Now at 84k miles one of the rocker arms is definitely failing and still not showing codes. The dealership will not cover replacement under warranty because the purchase date was 5 1/2 years ago. This is a known issue with the 3. 6l pentastar. Chrysler has provided technical bulletins to visually identify defective rockers but are not providing extended warranty or recall on this part. While at the dealership the technician said they handle a lot of rocker arm replacements on pentastar engines, 5 to 10 a week! Chrysler should take responsibility for sourcing and installing defective parts in their engines.
Tl the contact owns a 2013 Jeep Wrangler. While driving at an unknown speed, the vehicle automatically went into limp mode and the hot oil and check engine warning indicators illuminated. The contact also mentioned that the rpms failed to increase. The contact turned off and restarted the vehicle for the indicators to dim. The vehicle was taken to feeny Chrysler Dodge Jeep ram of midland (7400 eastman Ave, midland, mi 48642) where it was diagnosed that the transmission control module needed to be replaced and there was corrosion in the totally integrated power module. The vehicle was repaired, but the failure recurred a year later. In addition, the vehicle failed to start. The contact mentioned that the starter was replaced and the vehicle was driveable for two days; however, the vehicle stalled and the check engine warning indicator illuminated continuously. The vehicle was able to restart. The vehicle was taken to an independent mechanic and they stated that the fuel pump module needed to be repaired. The vehicle was not repaired. The manufacturer was notified of the failures. The approximate failure mileage was 62,521.
My Jeep was parked on the street in front of my house for about 13 hours and a electrical fire started on the front passenger side at around 3am. It burned half the vehicle before being put out and totaled out my Jeep. It also damaged the entire back end of the car parked in front of me. The fire department ruled this was a electrical fire and not arson. Days before I noticed the outside temp was reading at 119 degrees out side when the temp was actually 99 degrees. I'm not sure if this had anything to do with it but I found it very odd. I have read thousands of incidents similar to this some involving worst property damage and even cases with fatalities. I think Chrysler/Jeep need to be held accountable for this and get these dagerous vehicles off the streets ASAP.
