SERVICE BRAKES
Brake lines rusted out. Apparently this is an issue for this year and many other model year vehicles. Considering the brakes stop the vehicle, this is a big safety issue, and very expensive to be fixed.

STRUCTURE:INTERIOR PANELS:DASHBOARD, STEERING: STEERING WHEEL/HANDLE BAR
The Dashboard has cracked and broken in several places and I believe this to be directly as a result of the steering wheel column and moving the steering wheel tilt positions. You could hear a cracking when moving the steering wheel position and then a sound like a bolt or something dropping inside. After this happened there was a crack immediately above, perpendicular with the steering wheel in the plastic bent portion of the dash and since that time I have noticed the steering wheel seems to shift some even when you aren’t attempting to tilt it and the dashboard is cracking in several places now. This vehicle has never been left outside of the garage. It has been driven as a secondary, leisure vehicle and is in excellent condition so please don’t say this is normal. This is a result of something that occurred after hearing the snapping sound after the steering wheel was being tilted.

STRUCTURE:BODY
The structure that holds the rear differential and axle to the frame rusted through and broke off from both sides so the whole rear axle unit broke loose and pulled back so the drive shaft pulled loose and the rear tires were rubbing on the fenders. If this happened at highway speeds I don’t know what might have happened. The vehicle was towed to a welding shop to see if it can be repaired. It has not been inspected. If it can not be repaired the vehicle will have to be junked. There was no warning that this would happen.

The one piece dashboard has been cracking in multiple places for approximately 5 years. I see that there are multiple, multiple, multiple complaints regarding this issue across various models all of which occurred after the one piece dashboard was implemented. I also saw that a class action suit was filed and dismissed because this is not a “safety issue”. In my opinion, this is a safety in the event of an air bag deployment especially with the multiple cracks (which have occurred over the years). We take immaculate care of our vehicles and rarely trade them in under 10 years. We are also retired and don’t have the luxury of dropping 2k on a dashboard replacement. We respectfully request the replacement of the dashboard under manufacturer defect. Please advise if this is possible.

There is a problem with GM vehicles developing cracked dashboards including my own. The cracks are happening around/above the instrument cluster and more importantly, around the airbag. I am concerned that the defected dashboard would cause some sort of airbag puncture if it were deployed causing serious injury. Should someone get killed or seriously injured before this matter is taken into consideration. I own a 2012 Chevy Avalanche. I have developed the same cracks just as so many other GM vehicle owners.

The sunroof glass broke broke away while I was in the interstate going 70 miles a hour. It was so scary. Thank God there wasn't anyone behind me at the time. This could have went thru a cars windshield behind me and killed them. They need to build these better or be illegal in the US. I am putting a claim in with my insurance co. I don't know if it's covered. The garage that will be repairing mine said he gets many calls of this happening. Even though it's may not be a vehicle defect like breaks but it surly is a hazard issue. Even the insurance girl I was talking to said one almost hit her. She was lucky she was going up on the side of the vehicle that lost it and not behind it. This has not been a recall and something should be done about sunroofs. Extra brackets to hold them in maybe should be applied on any vehicle with a sunroof. I'm telling you it scared me to death when it broke. My heart was pounding and it could of caused me to panic and get in an accident. I had to drive with one hand holding my inside sliding cover. And if it had been pouring rain I would of had water pouring in and that would be an electrical issue. Please don't let this issue continue. Please have every vehicle with a sunroof recalled and have extra brackets added. Can you imagine if you was driving on the highway and a sunroof came flying at you. It would be worse than the ice on vehicles that is illegal. Never did I ever expect this to happen. I would pray this would come under highway safety. They are so dangerous. I will never purchase another vehicle with one again. I am waiting on the insurance co.
