Auto Repair in Knoxville, TN

Car repair in Knoxville

Knoxville drivers put their cars through a bit of everything: humid summers, a handful of hard freezes each winter, plenty of rain and the hills of East Tennessee. When something breaks, two pieces of local knowledge save the most trouble. One is a Tennessee law that tells you what a repair shop has to say before it touches your car. The other is the emissions question, which confuses a lot of people who move here.

The Consumer's Rights notice

Tennessee law, Tenn. Code Ann. section 66-19-104, in effect since July 1, 2001, says that before any repair work begins, an automotive repair facility must tell you three things:

  • You may ask for a written estimate for repairs that will cost more than $250.
  • You can't be charged more than 25 percent over that written estimate without your consent, or a good faith attempt to get it.
  • Repairs you didn't authorize can't be charged without your consent, unless the shop made a good faith attempt to reach you first, and that means at least an attempted phone call.

The shop has to print these rights under the heading "Consumer's Rights," right above the line where you sign. If the paperwork in front of you doesn't have that section, ask about it before signing.

What it means at the counter: on anything that might run past $250, ask for the estimate in writing. Give the shop a number where you'll actually answer. If the price climbs, you get a say before it climbs more than a quarter.

No emissions test in Knox County

New arrivals often ask where to get an emissions test. In Knox County, you don't need one. The Knox County Clerk's motor vehicle page says registration must be renewed every year and states: "At this time, Knox County does not require emissions inspections for passenger vehicles."

Knox County was never part of Tennessee's testing program, either. The state's inspection and maintenance program in the federal air plan covered only Hamilton County and the Middle Tennessee counties of Davidson, Sumner, Rutherford, Williamson and Wilson, and EPA's final rule approving its removal names exactly those areas. If a shop in Knoxville tells you an emissions test is needed for your registration, ask it to show you the rule.

The Clerk also lists a $36.00 wheel tax in Knox County for all motorized vehicles and cycles; it doesn't apply to trailers. That's a registration cost, not a shop charge.

Rain, heat and freezes

The National Weather Service's 1991 to 2020 normals for Knoxville give an average of 51.93 inches of rain and 4.6 inches of snow a year. Its period-of-record figures show an average of 34 days a year reaching 90°F or more and 68 days falling to 32°F or less. A few practical points follow:

  • Wipers and tires earn their keep in a city this wet. Check tread depth and replace streaking blades before the rainy months.
  • Batteries tend to fail on the first cold mornings, especially ones already weakened by summer heat. A fall battery test is cheap.
  • Air conditioning works hard on those 90-degree days. If it's blowing warm, ask for a leak check before a recharge.
  • Brakes and cooling take extra load on hilly routes. Mention it if you drive the ridges or the mountains often.

Short commutes count too

Census figures put the mean travel time to work in Knoxville at 20.2 minutes. Short, stop-and-go trips wear brakes faster than the miles suggest, and an engine that rarely warms up fully can collect moisture in its oil. Tell the shop how you drive when you ask about service intervals.

Before you book

  • Ask for a written estimate on any job likely to run past $250.
  • Read the Consumer's Rights section above the signature line.
  • Ask whether parts are new, used or rebuilt.
  • Ask how the shop will reach you if the work grows.
  • Keep the estimate, any approvals and the final invoice together.

Before you hire in Knox County

Get Auto Repair Pros doesn't inspect shops or check their registrations for you, so check for yourself before you approve any work:

  • Ask whether Tennessee requires auto repair shops to register with a state agency, and if it does, look the shop up.
  • Get a written estimate before work starts, listing parts, labor and fees.
  • Ask the shop to call you for approval before doing anything that isn't on the estimate.
  • Ask for your old parts back, or to see them.
  • Get the warranty on parts and labor in writing, including how long it lasts and where it's honored.
