Several incidents when accelerating, the engine goes into a limp mode, followed by indicator lights coming on P0401, P0299, P226C. The vehicle will not accelerate and travels at a max speed of about 5mph. This has happened in traffic every time and has put me and my family, as well as other vehicles, at extreme risk of being in an accident, not being able to accelerate out of the way of oncoming traffic. After several cycles of turning the vehicle off and on, it returns to normal function. The vehicle has been inspected at a Dodge Service station. They determined that the Turbo diesel system is malfunctioning and needs repair. My vehicle is available for inspection upon request.

In 2017 I purchased a recreational vehicle with a dodge chassis with the attached VIN. It currently has about 4500 miles on it. From the very beginning I have had problems with the transmission down shifting when traveling at highway speeds (55 to 65 MPH) which pegs the tach (7000 plus). This would occur when traveling up slight grades while on cruise control and would happen at random intervals (roughly 200 miles) without warning. I have been to the dodge dealer and discussed the problem with them. The first two times they didn't know what the problem was but said it was an "adaptive" trans which had to adjust to my driving and didn't offer any solutions. At the third visit to the dealer they reloaded new software for the trans, but still offered the "adaptive" argument, and still wouldn't guarantee a solution to the problem. I am afraid to drive this vehicle. When it down shifts there is so much engine braking and rapid deceleration that I fear a rear end collision. Additionally, driving on slippery roads (gravel, frost, snow, rain) could easily result in a skid and possibly complete loss of control.

This is new model for dodge in 2015 and comes equipped with the zf 9-speed transmission. At the lower end, the van lacks acceleration for passing or needed acceleration especially after deceleration. After reading the complaints about the zf transmission in the cherokee, the descriptions noted are exactly what is happening to my van. This is extremely concerning when on a freeway and once I slow down and then have to speed up fast, there is a delay or lull in the acceleration.
