2016 Jeep Grand Cherokee Fuel system Problems

“Severe bucking & jerking while driving. More moderate bucking while car is idle. Codes being thrown are p0406 & p0301. It has also thrown a p0402 as well. I've replaced the EGR valve as well as all spark plugs and the problem still has not been solved. My fuel mileage is tanking and driving the Jeep has become almost unbearable.”

This problem occurred a few days ago. I have even passed several chp officers on the road and have not been stopped when my speedometer was showing 105mph. Also, while pumping gas, it will not pump past halfway.”

“My car will randomly stall out when I slow down or come to a stop while driving. There have been at least 4 times where I've been stopped at a red light and it auto-stops and then doesn't start back up again when the traffic starts moving again. A message comes up on my dashboard telling me to shift to p and then back to my desired gear. I'll try to restart my car 2-3 times before anything happens. I've been on hills and on highways when this has happened and almost gotten into an accident on at least 4 occasions because of it. …”

Continued driving approximately 2 miles to get to an intersection to turn off the main road. Once stopped at the stoplight I noticed slight smoke coming from the left front corner of the hood by the headlight. …”

“28000 miles +\- driving car on freeway in high speed lane in las 405 - the most traveled highway in the us, and the car slowed to a dead stop. Complete loss of acceleration. All electrical still working, lights, dash, radio. Would turn over but would not start. Hour earlier car was idling and idled to a stall. All electrical still working. Police had to come and stop traffic to wait for a flatbed.”
