Buick Envision cruise control malfunction causing unintended acceleration and burnt rubber smell on Buick Envision

Some Buick Envision owners report experiencing cruise control malfunctions, which can lead to unintended acceleration and a burnt rubber smell. These issues may stem from a failed control module, sensor, or switch, which can disrupt the proper functioning of the cruise control system. Additionally, problems with the throttle actuation, such as a faulty throttle position sensor, can cause the engine's computer to overcompensate, resulting in unintended acceleration and black exhaust. A blown fuse related to the cruise control system can also interrupt power supply to critical components, further contributing to these malfunctions. Furthermore, issues with the throttle control system or the ABS may exacerbate these cruise control problems. It is crucial for owners experiencing these symptoms to seek inspection by a qualified mechanic to ensure safe driving conditions and prevent further vehicle damage.
