Spare Tire problems of the 2001 GMC Sierra

I own a 2001 GMC Sierra, I was driving from one job to the other when a person driving next to me flagged me down saying that I dropped my spare tire. I stopped and looked under my truck, I was missing my tire and the cable that was holding the spare tire was busted. Luckily the incident happened after school and speed limits were at 20mph. No one got hurt but if this would of happened while I was driving in a congested high speed road this could of caused a serious accident. The safty of all people are at risk of this happening as I experienced it myself. A 2001 vehicle should not have a part that can bust and drop a tire on the road. I took this report to champion GMC located in corpus christi texas. The man that attended me mel did nothing but give me a 200. 00 estimate for parts and labor repair. I believe that this part should be under recall before it causes a problem or death.
