New truck with 15 miles. bad vibration seems to be coming from both front and rear area at speeds of 64 to 72 possible tires out of balance or alignment.
Since day 1 of purchasing new,to current date, there is vibration at idle. there is vibration at highway speeds of 60 mph plus. it has been to the dealer 5 times for testing. this is a known problem with thousands of vehicles. gm says it meets their specifications. the dealer balanced the tires 3 times, no luck. the dealer replaced the tires, same issue. i am told the vibration at idle is normal. this problem is distracting when driving. i have been dealing with gm and the dealer for 7 months with no resolve. https://www.kshb.com/news/local-news/investigations/general-motors-customers-frustrated-over-shaking-in-pickup-trucks this link of a news clip shows what is happening to my vehicle. this happens every day, so ignore the date i entered below. i have videos but the file is too large to download. *tr
