If your vehicle is showing convertible roll-over protection bars deployed without a crash, here are the most likely causes and the parts you'll need to fix each one.
Hitting a large pothole, taking a speed bump too fast, or aggressive cornering can generate enough G-force to trick the sensors into thinking a rollover is imminent.
The sensor that monitors the vehicle's tilt and acceleration can fail internally, sending a false deployment signal to the safety system.
Convertibles are prone to cabin leaks. If rainwater or car wash water reaches the body control module, it can short the circuits and trigger an uncommanded deployment.
The rollover bars are spring-loaded and held in place by mechanical latches. If a latch mechanism wears out or breaks, the bars will release and pop up on their own.
Damaged, chafed, or pinched wiring under the rear seats or trim can create a short circuit, sending uncommanded power directly to the release solenoids.
