2014 Jeep Grand Cherokee service brakes problems

“My 2014 Jeep Grand Cherokee began popping out of gear (aka shifting into neutral suddenly) while at cruising speed several months ago. This causes the car to lose drive altogether at highway speed and requires the driver to pull to the side of the road in order to restart and resolve the issue. Before the restart, the power brakes fail to work any long and the driver needs to press very hard on the pedal in order to keep the vehicle stopped or slowed. This has no put myself and the drivers behind me at significant risk if the driver (my daughter) or me are unable to pull to the side of the road safely or if the cars behind us cannot avoid us. My mechanic cannot diagnose the issue. We changed the transmission and the problem has persisted. There are no warning lights or check engine lights associated with the error. It seems very similar to what's happening here -> [XXX] However, the Jeep dealership wants way too much money to diagnose the issue. I've seen the issue reported by other 2014 Grand Cherokee owners in forums with no resolution.”

“I am reporting a serious safety concern involving the transmission/power train of my 2014 Jeep Cherokee Limited, VIN [XXX], with fewer than 80,000 miles. The transmission failed suddenly when I was approximately one minute away from entering a highway. The vehicle became inoperable and left me stranded in an isolated area with little or no cellular reception, and I had to find assistance. Had the transmission failed one minute later while I was traveling at highway speed, I could have been seriously injured or killed. I could have died because of this failure. Or I could've killed or injured someone else on the road. There were no meaningful warning lamps, dashboard messages, or other advance warnings that alerted me that a complete transmission failure was imminent. The transmission failure was confirmed through the repair process by the service facility that repaired the vehicle. The transmission has already been repaired, and I have repair invoices, diagnostic records, and service documentation available upon request. I was without my vehicle for nearly one month while the issue was being addressed. The vehicle has not, to my knowledge, been inspected by…”

“The vehicle has a severe, life-threatening safety defect where it randomly drops into neutral while driving at speed, physically locks the shifter, and actively engages the electronic braking system on its own, stranding me in active traffic. I brought the vehicle to a certified Jeep dealership to resolve this exact symptom. They misdiagnosed the vehicle and charged me nearly $3,000 to replace the valve body and connectors. The dangerous symptom remains completely unchanged, meaning the vehicle is unsafe to operate and the manufacturer-certified repair facility has failed to remedy a critical safety defect. The issue hasn’t been fixed and it has been 5-6 months.”

“I am reporting a safety-related issue involving a 2014 Jeep Grand Cherokee Summit 5.7 HEMI. Within days of purchase, the vehicle experienced transmission slipping and delayed shifting, as well as braking issues. These conditions affected drivability and raised safety concerns during normal operation. An independent mechanic found burnt transmission fluid, indicating that the transmission condition likely existed prior to purchase. Although a fluid change provided limited, temporary improvement, delayed shifting continues to occur. Because the transmission behavior and braking issues can affect the safe operation of the vehicle, I am submitting this report so the issue can be documented and evaluated for potential safety trends. This report is being submitted for safety tracking purposes.”

“The Anti-lock braking system and the electronic traction control system are both failing. There were previous recalls on both systems that say they have been repaired, but the lights for both are constantly on. The brakes do not work fully, and it has caused me to slide down the street from my workplace. The electronic traction control system not working has caused it so that my four-wheel drive does not work, and I have gotten stuck in the snow multiple times. The car has been inspected by a repair technician. The warning lights came on right as the problem was happening.”
