I was driving on the highway and the vehicle shut off while I was driving at 70 mph. Lost power steering and brakes out of no where which is when I noticed the rpms was at 0. After we, by the grace of god, made it to the side of the road safely, we had it towed to a garage where the said the timing chain came off and ruined the engine and that it is a common problem and could be fixed for around $5600. The vehicle has 65k miles and blew up? its a common problem for a vehicle to shut off on the highway and I wasn't warned that this vehicle has this kind of history and gm don't recognize this is a problem!.
2011 Chevrolet Traverse lt was first told around April 2014 following an oil change at my local gm certified dealer that there was a leak around the power steering system (I cannot remember the exact term used). Anyway, the service tech said that it was clearly a slow leak and not causing any urgent problems, but that I should pay attention to it should things change. The next 2 or 3 oil changes, the same issue was noted. During a routine oil cahnge may 2105, I was told there was a seal leak to the engine of some sort but it was 'warrantied'. So, I authorized the repair, of a leak that I never noticed/had issue with. Fast forward to July 2015 (68,000 +/- miles) and my power steering is leaking puddles, the resivoir remains full, and suddenly lose all power steering capabilities. Call same gm dealer I always use, as I notice on the unrelated repair in may, the power steering components were messed with, flushed, etc. To allow for proper repair of other issue. I was told about a 'warranty extenstion' for the power steering pump and to bring it in, it should be a covered repair based on the notes the service tech could read pertaining to my vehicle. Call back today (8/3) and am told that while the pump is covered, nothing else is (despite from my research the pump failure is likely causing the other noted issues) and the repair for the rack/gear box + alignment + flushing + whatever else he rattled off to me, would be at my expense, with a quote of $2100+/- from everything I have read and researched, this is an extremely common issue that gm refuses to address in order to properly repair at their expense vs. The expense of vehicle owner. Clearly this is a massive and widespread gm issue with vehicles in this class.
