I am requesting that dot NHTSA investigate the extreme wobble/vibration/shake on new 2017 Chevrolet Silverado 1500. The vehicle was purchased new and driven under 55 mph for the first 500 miles. After the first 500 miles and beginning to drive highway speeds, between 60 - 75+ miles per hour, a wobble/vibration/shake began to occur. When the wobble/vibration/shake begins the driver feels that control of the vehicle is being lost and the driver must decrease the speed, which is able to be accomplished with both releasing foot off of the accelerator or lightly breaking, in order to regain control. The vehicle has been to the dealer for front left wheel replacement due to the inability of original tire to be balanced, the vehicle has field force balancing 3 times, and the left front axle boot has been replaced. After several attempts to correct the wobble/vibration/shake, the vehicle now has ~10,000 miles, the wobble/vibration/shake continues to occur at highway speeds.

Bought the truck 16 Nov 16 in Idaho. Noticed at the end of Jan/early Feb '17 that paint chips/knicks were starting to appear all over the truck and in places where the only way you could see them was to the open a door (I.e. not even exposed to the road). After making numerous inquiries to local GM dealerships, all of whom said it was sand damage, I started doing research. Turns out, I'm not the only person with this issue on their trucks. It appears the issues with paint on GM (both GMC and Silverado) trucks started around mid to late model 2014 trucks and persists to this day (see attachments). Additionally, my local dealership here in reno, I have found out, has been lying to me; they told me they submitted two separate requests to GM for the truck to be repainted as they agreed with me (in-person and via phone) that something is wrong with the paint. It turns out, this is all a farce. The two requests they submitted stated, "customer has been advised to file a claim with their insurance as damage is caused due to sand damage. Customer insists dealership submit a claim to GM for warranty re-paint". whilst I'm paraphrasing here, I was livid to learn this was 'their behind my back kind of thing'. prior to learning about this shenanigan, I thought for a second that perhaps the dealerships could be correct, maybe it could be damage from driving. So, I took it to three separate repair facilities in the area and all of whom said the same thing, verbatim, "the clear coat is too hard, it's like glass. Factory defect". well, that confirmed it. Lastly, I have just recently contacted the dealership from which I bought the truck (Idaho). They advised me at 1352 on 23 May 17 to escalate this issue beyond GM. And that's why I'm filing this complaint folks. Do your homework before buying any new GM product.
