The horn on my vehicle does not operate, creating an extremely dangerous situation for the driver, as well as other vehicles and pedestrians on the road. This is a known problem, addressed by gm "special coverage 10276". Unfortunately, that special coverage did not fix the problem, and gm implemented an extremely low mileage limit so it does not apply to many affected vehicles. This pervasive problem has been known by gm for years both in the USA (with the Saturn Astra) as well as the identical vauxhall Astra and opel Astra in europe.
Vehicle horn is intermittently inoperable. I have had two near misses due to the non functioning horn. When it is not functioning, depressing the horn button turns the radio volume instead. At the same time the left steering wheel buttons are inoperable. Occasionally the radio volume will lower on its own, then return to normal. This problem is common oversees in the opel / vauxhall versions of the Astra. Replacement of the wiring harness and cim module have only temporarily resolved the issues there. This issue has persisted on and off in my vehicle for several years. The condition exists while stationary and in motion. The car is mostly driven short trips in city traffic. The car is 8 years old, 52,000 miles.
