Rear Suspension Springs Problems of Chevrolet Silverado 1500

Started to hear clunking noise around 15,000 miles. The noise started to get worse as time went by. First it was just when driving up my driveway then it was while driving or even stationary pushing down on the rear bumper. Found that the leaf springs were cracked but it wasn't visible while they were on the vehicle.

Extreme rust on under carrage of vehicle. Brake lines rusted out causing brake failure frame rusted out at rear leaf springs and frame rail cross members. Rear shock hangers rusted off vehicle. Frame rusted so bad that it prohibits toung of any type of trailer. Toyota had same problem and they had to do a recall so why has gm not had to do the same thing. It is a very large safety issue affecting many vehicles on the hwy today.

The contact owns a 2009 Chevrolet Silverado 1500. While driving approximately 25 mph and making a left turn, a loud metal popping noise was heard outside the vehicle. The contact maneuvered to the side of the road and noticed the rear passenger side leaf spring was fractured and remained connected to the assembly. The vehicle was taken to an independent mechanic where it was diagnosed that the leaf springs needed to be replaced. The manufacturer was notified of the failure. The approximate failure mileage was 48,000.

The steel in the rear leaf springs suddenly broke in half (under no load). It happened twice - in the left rear leaf springs in ~2016 (~3 years of age), and again in the right rear leaf springs last week (2018). This is not even a mechanical device - just a passive heavy gauge piece of steel. The vehicle is very light use, and in both cases there was no payload in the flatbed. Gm appears to be using a substandard grade of steel in critical areas of the vehicle. The rear of the vehicle dropped when the springs broke, and I consider this a safety problem if driving at high speed. In addition, the steel rod that connects the inner driver door handle to the door lock, also snapped (so you can not exit the vehicle from inside controls). It appears that gm is using a cheap substandard grade of steel in their vehicles. Estimated date of first event below.

Rear axle has a gvwr of 3950 lbs the vehicle a 2plus 1 rear spring pack, 3 diferent spring suppliers rate this spring pack at 1425l or 1500 lbs each for a combined rate of either 2850 or 3000 lbs per pair. Which makes the factory rating of 3950lbs either 1100 or 950 lbs higher depending on the spring supplier. Using the industry guideline the weakest componet controls the gvwr is being violated by Chevrolet I have a truck marketing institute certificate in this area and a cd from michelin verifing the weakest componet controls gvwr. I asked Chevrolet for replacement springs from another model that has a combined rating of 4050lbs 100 lbs above ther 3950 lb axle rating. This issue has caused trailering problems but Chevrolet refused this is a safety issue the springs I requested would correct the problem can you help ? I can supply further information if needed thank you.
