Adaptive Cruise Control problems of the 2019 Ford Edge

While driving on the highway the vehicle lost all power and it completely shutdown which was very scary. There was never any warning lights on dashboard and was told it was probably due to bad gasoline. Now the cruise control is shutting off an long with hesitation. Again no warning lights. Ford dealership said it was the spark plugs and coils, wanted to charge me $800! local mechanic ran a diagnostics confirmed it is the torque converter…alot of confusion with Ford diagnostic . This is a huge safety issue when driving in traffic, is very expensive and needs to be addressed.

The start/stop technology works from time to time. Example. At a complete stop icon appears and show’s technology off- the device is not off. At times the technology will engage at a complete stop then suddenly turns off with in seconds. At times when this device is on one can hear a rattling noise. When leaving from a complete stop and applying the gas petal lightly the vehicle jumps/hop roughly 6” to 1’ without adding additional pressure to the gas petal. When using the advanced cruise control with no vehicle in front of mine and have set the mileage which can been seen on the control panel the vehicle will keep the mileage speed for 3-6 seconds then decrease in speed up to 10-12 miles. If applying the brake when using cruise control and re-engage the speed (res button) the vehicle speeds up continuously at a very fast unsafe pace. The advance lane shift will warn me (turn red based on which lane it thinks I have crossed) I have steered out of my lane (low setting) but haven’t cross any lanes. Will use turn signals to change lane and lane shift turns red again to inform me I have steered out of my lane. This should not happen. Back up camera at times screen is black. Rear sensors when backing up even with large objects (persons- adult, another vehicle, garbage truck) will not notify me of objects. Now I can see the objects and don’t proceed but the sensors don’t go off and there are four. Brought vehicle to akins Ford in GA. Went for observation ride. The foreman noticed many issues including cruise control, after braking- SUV leaping, sensors, backup camera. But felt there were no safety issues.

Was driving on freeway, in the middle lane, and card just started slowing down for no reason, pressed gas and it still was slowing down. It felt like the brakes were being applied even though I was just pressing the gas. Finally it stopped and I turned the car off and then back on and the problem went away. I think it was the adaptive cruise control and not the collision avoidance because no warnings came u on the dash. Luckily the cars behind me were able to stop without rear ending me but they sure were angry with me.

While driving on the highway I experienced an apparent loss of power. It happened on an uphill grade and persisted for the duration of my trip – approximately 25 miles. The problem seemed to only occur on an uphill or flat road. The problem was not evident going downhill. Going home (approximately 32 miles) a few hours later the problem persisted. For about a week nothing happened, and then the problem reoccurred on the highway while coming back from dinner. Since then it has sporadically reappeared getting more frequent in the past few weeks. The symptoms are a complete loss of power, especially on an uphill grade. Lifting my foot off of the accelerator will temporarily bring power back, but trying to accelerate will cause the car to lose power again. If I continue to press the accelerator, the car will eventually come to a complete stop. Now the problem seems to happen at almost any speed and any road condition, uphill, flat, and occasionally downhill. During one occurrence I noticed something. When the problem happened I could see the brake light reflected on the rear window. So in addition to the loss of power, the brakes were activated without me applying the brakes. In discussions with the service manager at the dealership, we both believe the problem may be related in some way to the adaptive cruise control. It would make sense that if the adaptive cruise were activated not only would the brakes be applied, but the system would also shut down the engine. The car has been to the dealership four times for diagnosis. The last time they had it for more than a week. Neither they nor I can make the problem occur on demand.

When both adaptive cruise control activated and lane keep assist activated, the Edge st bounces in between the lines on the road, instead keeping the car center in the lane. Lane keep assist censors and software need re-calibration.
