I am writing to express my profound disappointment and frustration with the service I received at the Costco Tire Center in Wheaton, Maryland. On October 23rd, I brought my car to the center for a routine tire rotation, and the outcome was nothing short of a troubling ordeal. While performing the tire rotation, the technicians at the center found and informed me that a lugnut and a stud on the rear left wheel of my vehicle were damaged. Over the phone, I told them that I only had the tire serviced at their center before so if there were any damages to the wheel, they must have been the fault of the center. They told me to complete a claim form and seek repairs at a different auto shop. After filling in the form, I asked two staff members and got confirmation from them that I could go ahead with the repair and could return to Costco Tire Center with a receipt for reimbursement. I complied with their instructions, and on October 24th, I had the damaged components fixed by a Firestone shop at a cost of $350. Eager to have this issue resolved, I revisited the Costco Tire Center in Wheaton on October 27th, expecting to have the tires properly rotated and to receive the promised refund for the repair costs. To my dismay, the staff and the manager at Costco Tire Center attempted to avoid their responsibility and dragged their feet in addressing my concerns. They cited the need to review security camera footage to confirm the agreement made regarding repair and refund, as well as claimed that my case required higher management intervention. Furthermore, I was informed that another lugnut and stud on the same wheel were found to be in poor condition, and they refused to perform the tire rotation. It's important to note that I had purchased my tires from this same center in September 2022, and they had been exclusively serviced by Costco Tire Center for rotation. The implication is clear: any damage to the lugnuts and studs must have occurred during their previous service visits. This situation is not only exasperating but also erodes the trust I once had in Costco Tire Center in Wheaton. It's worth mentioning that this is not an isolated incident. In March, the same center caused a similar problem, but at that time, they promptly acknowledged their mistake and refunded me for the repair. While it inconvenienced me, I appreciated their commitment to rectify their error. However, this time, their conduct has been nothing short of evasive, casting doubt on their willingness to uphold the service commitment associated with the tire package I purchased from them. I strongly urge other customers to carefully reconsider conducting business with this center. My experiences have left me deeply dissatisfied, and it is apparent that they need to address their negligence and stand by their service commitments.
