C1980 on Ford
Adaptive Cruise Control Sensor Blocked
C1980 on Ford vehicles indicates adaptive cruise control sensor blocked. Au7o has documented this code across 1 Ford model — most commonly on Flex. This is a chassis/safety code indicating the adaptive (radar or smart) cruise control sensor is blocked and cannot see the road ahead clearly. The forward-facing radar or camera that measures the distance and speed of vehicles in front is being obstructed, so the system temporarily disables adaptive cruise and any related collision features. It frequently appears in bad weather or when something physical is covering the sensor. Often it clears once the obstruction is removed. Typical repair costs on Ford range from $300 to $2,500, depending on the specific model and root cause.
Common Causes of C1980
- •Snow, ice, mud, or rain buildup on the sensor or bumper
- •Dirt, bugs, leaves, or road grime covering the radar
- •License plate or accessory blocking the sensor
- •Misaligned radar after a minor impact or bumper work
- •Sensor needing recalibration after repair or alignment
- •Faulty radar/camera sensor unit
- •Damaged wiring or connector to the sensor

Ford Flex(1 issue)
- Power Transfer Unit (PTU) Seal Leaks and AWD System Failure2009-2019
AWD-equipped Ford Flex models suffer from chronic Power Transfer Unit (PTU) seal leaks and eventual PTU failure. The PTU transfers power from the transaxle to the rear driveshaft and is sealed with halfshaft seals that deteriorate over time. When the seals leak, the PTU fluid level drops, causing the unit to overheat and produce metal shavings that destroy the internal gears. Ford issued a TSB acknowledging the problem but never recalled the part. The PTU has no dipstick and the fluid is considered "lifetime" by Ford, meaning most owners never check or change it — leading to premature failure.
