2014 Jeep Grand Cherokee: adaptive cruise control problems

Filed Sep 5, 2026 · Acceleration, Electrical · MA · crash

While maneuvering in a parking garage and switching between reverse and forward, the engine suddenly and unprompted revved excessively, sounding as though the accelerator pedal was floored. The vehicle forcefully lunged forward against braking pressure into a cement wall, causing front-end damage to the vehicle. Cruise control was completely disabled and no check engine light or warning indicators illuminated on the dashboard. At no time did I feel like I had control over the car. I sustained some contusions. No one was in the vicinity at the time; however, other cars and/or people could have been struck. The vehicle has yet to be examined by anyone although I am in the process of arranging for an autobody repair shop. Prior to this, the car was in its usual state of health without any issues.

While using cruise control and traveling at a speed of approximately 70 miles per hour on the highway, my car accelerated on its own and ai had I had to hit the brakes. I was thankfully able to slow it down, to which the entire car shuts down. The vehicle completely shut off and would not start. I had to have it towed to Jeep and they told me it was not one, but BOTH fuel pumps had failed. They charged me over $1700.00. There is currently a recall for this very issue and Jeep made no attempt to fix it. I had no idea there was even a recall for this until now and this happened a few years ago.

Cruise control Didn’t disengage and continue to accelerate. Tried to apply brakes but they went straight to the floor and didn’t work. Placed the car into neutral and kept trying brakes until they started to come back. With the car continuing to accelerate went into breakdown lane and rubbed up against guardrail to avoid car in front.

The check engine warning indicator eventually illuminated after the failure persisted for some time.

The headrest of the drivers seat deployed while I was driving. I was driving on a highway with cruise control and and the vehicle was at a steady speed with no sudden jolts or stops. I heard a very loud pop and the headrest hit me in the back of the head. The incident startled me and caused me to hit my breaks.

In the process of parking at my sister's home, I took my foot off the accelerator and started to brake. The car did not slow down. I continued to brake, but the car kept going forward with increasing speed. I was able to steer and not hit parked cars, but went into the lawn hitting a set of contractor's scaffolding sending them flying into their house and patio. The car finally stopped on top of their well head, destroying the well cover as well as the protective pipe for the well head. Further internal damage was done to their well, as there was no running water in the house. A tow truck had to come to lift the car off the well head to avoid any further damage. I had been using the cruise control earlier in our trip, but it was not active at the time.

Driver seatbelt does not retract to tighten on driver while driving or stationary. Serious safety issue! Additionally, none of the controls on the right side of the steering wheel work ever; cruise control, park assist, lane departure warning, etc.

Multiple problems with the forward collision warning (fcw) and adaptive cruise control (acc) systems 1) system will issue false brake warnings (and apply brakes if enabled) on clear straight roads with no other cars or obstructions. 2) system will disable itself at random intervals disable itself for a period of time (10-20 minutes). Only notification is brief "fcw/acc system disabled" notification in gauge cluster - no audio warning that important safety system disabled itself. 3) when using acc, when vehicle resumes set speed after autonomous braking, vehicle will accelerate into back of next vehicle ahead - have to manually intervene and apply brakes to prevent collision. Note that this vehicle uses a bosch lrr3 radar sensor system for the fcw and acc features. Vehicle has been into jeep dealers for service for this issue five times, and even after opening star case with jeep/chrysler fca, still no fix for this serious safety issue.

Adaptive cruise control and collision avoidance did not work properly, and resulted in a collision. I was driving on a highway, relying on the adaptive cruise control and the automatic braking, a feature of collision avoidance. There was a slow down in traffic, and although the system slowed down and applied brake, it did so too late to stop car. As I got too close, I applied steady pressure on the brake, but I still hit the car in front of me, who then hit the car in front of them. No significant damage to either of the other cars, and mine has minor cosmetic damage, and the adaptive cruise control is now not working properly. Could have been significantly worse. Makes me really question the potential for self-driving cars.

My emergency brake light is flashing on my dash board, and it is making a chiming noise when flashing as I drive my jeep. The main issue other than having it going on and off some time a few time a day sometimes not for a week than a few days in a row is that when I am on an open highway with cruise control on doing 70 MPH the cruise control will shut off every time it flashes. I fell the this is a safety issue when your cruise controls shuts down without any warning. The dealer has not corrected this issue. I just got a recall notice to day s27/the federal safety agency 16v‑240 to make sure my vehicle is in park and foot brake on. My foot brakes says it is on at 70 MPH when it is not on. This happened a lot today on my trip, but has been going on for over a year
