Service Engine Light On problems of the 2007 Saturn Aura

Remote start failed to turn over engine only signaled headlights to flash. Upon starting car with key in ignition the service engine illuminated and has not turned off to this day. Was able to bring into local Chevrolet service dept for recall 13036 for brake lamp malfunction and have diagnostic on service engine light on may 6th 2015. Dealer states current code of p0017 and history codes p2070 and p0019. Dealer claims cause is a stretched timing chain and worn guides and wants an engine tear down to replace timing chain, guides, covers and examine camshaft timing. Estimated cost is $3271 and 2-3 days to repair. Current mileage is 100,877 and manufacturer is refusing to cover any part of the repair. I have been researching this repair and seen complaint after complaint in regards to this engines timing chain failing. Complaints range over a series of makes, models, and engines and appears to be a known issue on general motors part for years and there has been no recalls or corrective actions. I also have an issue with the passenger air bag sensor intermittently turning off the passenger air bag while an adult is sitting in the seat. I was informed by the dealer that this is caused by a failing sensor inside the passenger seat. The seat would need to be removed and disassembled to replace the sensor an appx $800 repair. Again another common complaint and repair the manufacturer is refusing to cover. My car is regularly maintained with records available. I can not afford to pay $4000 in repairs that should not need to be repaired at consumers cost. These serious conditions need to be addressed by general motors and possible recalls issued. It's sad that the manufacturer dumps their consumers once they cease production of a brand or model. Please investigate and advise us unfortunate owners.

I own a 2007 Saturn Aura xr I bought in 2008. It has 69,600 miles and the service engine light is illuminated. I was told I needed a timing chain replacement for $2400. 00 because it had stretched. I have since found out that gm has a special coverage adjustment #11340c on the 2007 Saturn outlook and numerous other vehicles, for the same issue. My engine code is ly7, same as the outlook and other vehicles. Additionally I've already had 1 recall on this vehicle for a brake light issue, just got a notice of a transmission issue, and I'm on my third set of complete brakes in just 69,600 miles and I need all new brakes again. Rotors are warped after10 to 15,000 miles! also the "service traction" light keeps illuminating periodically for no apparent reason. I'm getting no answers or help from gm or it's dealers.
