“Have been waiting for several months for Ford to remedy BOTH recalls. There obviously is no important reason for them to be productive and do the right thing so this issue will likely never be resolved unless I take action and file a complaint. The two issues are not even that critical so I further don't see why action has not been taken. 1. Interior A pillars separating. 2. Back up camera screen on infotainment center.”

“APIM is failing due to current recall with reverse camera. The glitching has cause many safety issues including •Navigation Fault •Cracking/popping audio •Missing touchscreen sounds •Intermittent system issues •Slow loading •Camera freezing or blacking out This has already caused a collision with my vehicle. Took it to manufacturer (Ford dealership) and they told me nothing they can do until recall has parts ready. Prior to all this, my car system was working just fine up until August 2025. No issues AT ALL.”

“Hands-free connection to phone-Bluetooth. This happened a year ago. I believe around Sept 14th 2020. 6 days after warranty expiration the Sync3 hands-free system died on my Flex. I only had 32000 miles at that time. It was touted as a great safety feature when I purchased the car brand new. I live in Branson Mo where every road is curvy and drops off into ravines. The system is totally inoperable. Called Ford 800 number, they checked and told me they would not do anything with it. …”
