Business ProfileforMcGrath Acura of Downtown Chicago

On 9/2/23 I purchased a used 2019 Infinti Qx50 (***,Essential) with less than ****** miles from Mcgrath Acura of Downtown Chicago. A few months after my purchase I began to hear a knocking sound coming from the rear of the vehicle and took it to Infiniti of Clarendon for inspection. At Infiniti they informed me that the rear differential was completely damaged and needed to be repaired. Upon inspection of the vehicle they determined that the result of the damage was because the rear left tire was a different size and brand from the other 3 tires. Since the vehicle is all wheel drive, all 3 of the tires need to be the same exact size and brand. When the tires are different size this causes issues with the powertrain for multiple reasons. The tires being the same size is important for *** vehicles as this ensures that the *** system won't experience unbalanced wear and that there's balanced traction at all four corners. Selling someone an *** vehicle without disclosing that the tires are different brands/sizes is predatory as no one would purchase the vehicle knowign this. The saleswoman, ***** did not disclose that the tires were a different size when she sold me the car. I have tried to contact Acura of Mcgrath to get an explanation for how an *** vehicle would be sold to a customer without empasizing that the tires were different. But, everytime I call I am directed to the next person and told that I will get a call back later and never do.
