The tpms system failed to warn of low pressures, including flat tires and driving on a spare. tpms failures should "failsafe" and not fail silently.
The dealership left the shipping blocks/pucks/discs on the struts. this is a common problem as evidenced through many online forums. the dealership and many others claim that this does not cause a problem; however, the blocks prevent the suspension from doing its job, which is absorbing impact, improving braking, and helping the wheels maintain contact with the ground. i drove over 18000 miles not realizing that they were on (i just thought i have a tight suspension). i have now lost 4 tires (premature wear and bubbles/punctures) and have damage to the strut and steering knuckle. this is a potentially dangerous mistake.
