Business ProfileforEarnhardt Buick GMC

After nearly 3 months of being told parts had not arrived for warranty work 10/19/23- approx. 01/12/24, I drove to the dealer and spoke with Manager of the service department. They found the parts were in stock and I booked the appointment for 01/15/24. During the inspection and replacing the pressure monitors in the front tires, they found the front brakes were due for replacement recommended rotors as well. Although I had no vibration or noise coming from the brakes and front tires, I knew the pads were getting close due to previous maintenance inspections, so I authorized the maintenance which was completed and paid on 01/18/24. Over the next few weeks, I needed to drive on the highway and noticed a vibration in the steering and pulsing when breaking from highway speeds. I spoke the service advisor on 02/21/24 and scheduled it with them on 02/23/24. I picked it up EOD and was told they didn't see anything wrong with the brakes, but they had run a road force test on all four wheels and 3 of the 4 tires needed replacing. I told the service advisor that all four tires were new within the last 7 - 9 months and I'd had no issues with vibration or braking prior. He insisted it was the tires had gone bad at some point so we discussed options and I chose to have the tire shop look at the tires for possible replacement under warranty. At the tire shop, I explained the issues to the Manager and he walked with me to the parking lot and visually inspected the tires. He explained over torquing the lug nuts could cause these issues and after retrieving his torque wrench, he tested two lugs on the driver side wheel and found they were torqued to at least 175lbs (he stopped testing there) when spec was ~140. On 2/24 I spoke in person to a different service advisor and was told I would get a call back. I've followed up several times via phone and two voicemails, but no call back. $5k+ warranty, $1k+ paid by me.
