Thorne Bay Auto

4.2
(35 reviews)
Verified

The primary and only full-service automotive repair shop within Thorne Bay itself. As the local community's trusted mechanic, they handle general maintenance, diagnostics, and repairs for all domestic vehicles, including GMC trucks. They are the first stop for most residents for issues like check engine lights, brake service, suspension work, and basic electrical diagnostics. For highly complex specialist work (e.g., internal Duramax or Allison transmission repairs), they would likely facilitate the process of sending the vehicle to a specialist in Ketchikan.

Located in Craig (approximately a 30-minute drive from Thorne Bay), this is the most highly-reviewed and capable automotive shop on Prince of Wales Island. They have a strong reputation for working on domestic trucks and SUVs. Their technicians have broader experience with diesel engines and complex transmission issues than what is available in Thorne Bay. They are a common choice for island residents needing more advanced repairs without the expense and logistics of going to Ketchikan.

Based in Ketchikan, this is the closest provider that offers a near-specialist level of service for GMC vehicles. Ketchikan is accessible by a ~2.5 hour drive and ferry. They are known for their diagnostic capabilities and experience with modern computer-controlled systems found in GMC trucks, including Duramax and EcoTec engines, as well as Allison transmissions. For major repairs, warranty work, or issues requiring proprietary GM diagnostic tools, this is the most practical "specialist" option for Thorne Bay residents.
