Auto Repair

That annoying check engine light. Has it come on again? Can’t you just ignore it? No, ignoring the check engine light is never a good idea. You don’t want to put off any small maintenance or repair jobs on your vehicle. These little problems can turn into big problems in a hurry. At Ethan’s Honest Automotive we can check the following systems.  

  • ABS Lights
  • Traction Control Lights
  • Electrical Diagnostics
  • Vibration Issues
  • Shakes in Steering

Oil Changes

Getting your oil changed does not have to be a stressful thing. It is one of the most frequent pieces of vehicle maintenance you will perform. Don’t worry about taking time out of your busy schedule to change your own oil. Contact Ethan’s Honest Automotive and let us do the job for you. We will drain the old oil and replace the filter. 

Brake Service

Brake problems can be serious. If you experience any issues with your brakes, you need to contact a team member at Ethan’s Honest Automotive right away. Our technicians will check the following parts. 

  • Master cylinder
  • Brake hoses
  • Brake linings
  • Drum hardware
  • Brake fluid
  • Brake lubricant
  • Wheel bearings 

We may need to replace or clean any or all of the above parts. Doing so will ensure that your brakes continue to stop your vehicle well, which is imperative for your health. 

A/C Service 

A broken A/C is a nuisance that can cause a very hot vehicle. Contact Ethan’s Honest Automotive when your vehicle’s A/C stops blowing cold. There is no reason to suffer in the heat this summer. 

Suspension service

Working suspensions are also essential for a comfortable drive. Without a suspension, your drive will be very bumpy. A really bad problem may even cause your vehicle to not be drivable. Don’t let your suspension get this bad. Tell the professionals at Ethan’s Honest Automotive that you need your suspension looked at. They will check the following to determine where the problem lies. 

  • Shock and strut 
  • Power steering 
  • Suspension fluid
  • Tire wear
  • Bushing or mount

Transmission service

It is impossible to drive a vehicle without a working transmission. However, you can drive your car with old transmission oil. That is a problem. Just like you don’t want old engine oil, which is why you have your oil changed so frequently, you don’t want your transmission to run with old oil. It can be dirty and gum up the gears. When Ethan’s Honest Automotive changes your transmission oil, we can also

  • Change or replace the screen or filter
  • Clean the pan
  • Install a new pan gasket

Tune-Ups

Vehicles, like humans, need a check-up every once and a while. That is why tune-ups are so important for your vehicle’s long-term health. We recommend a yearly tune-up. During it, our professional will perform a 

  • Engine inspection
  • Spark plug replacement
  • Air filter replacement
  • Fuel filter replacement

A tune-up will help your vehicle run more efficiently. It will also allow us to spot any other problems that could flare out of control over the year.
