**** GMC Sierra **** SLT. Vehicle has been in the Heyward Allen Toyota*GMC Buick Collision Center since *-*-****. On **-*-** collision center discovered replacement exhaust system was damaged beyond repair and would have to reorder another replacement. I have been advised three times since **-*-** the last time **-**-** the center has not been able to secure another one by GMC. That the part is not available at this time and they have no estimated time when they will receive it. GMC needs to provide replacement parts in a timely manner for their vehicles. As of **-**-** the vehicle has been at the center for ** days for what I was told would be a ** day repair job. I request the help of GMC to procure a replacement part ASAP. Thanks.
