Warning Lights Questions and Answers

Q: Why Is My Car's ABS Light On?
A: An Anti-Lock Braking System or ABS warning light on your dash indicates something in your car's ABS needs to be checked out by a qualified mechanic. Your ABS is one of your most important safety systems. Do not ignore this warning light. Common issues are:
  1. Malfunctioning ABS module
  2. Low levels in the brake fluid reservoir
  3. Broken speed sensor
  4. The ABS system is not receiving power
Q: Why does my car keep saying the coolant level is low?
A: If a low coolant warning light is on do not continue to drive and go directly to the auto repair shop. It is simple and often inexpensive to fix at B & M Automotive & Diesel Service. Waiting to get the problem resolved can result in high-cost engine repairs. If the low coolant warning light continues to flash on, then there is a leak in the car's cooling system. Coolant fluid can leak in several ways. First, external leaks from radiator hoses, second, connections between hoses, or lastly, from the radiator itself. Your car's radiator cap may leak due to a faulty seal on the cap which can be easily resolved by a specialist at our shop in Knoxville.

Q: How do I fix a persistent traction control warning light?

A: Normally, when the traction control light comes on while driving it indicates the car's traction control lost grip or traction going around a sharp curve or while driving on wet pavement. However, sometimes the traction control warning light will come on and stay on.

The best way to determine whether it was just a fluke or a real issue is to shut your vehicle off and turn it back on. If the light is off, then it was likely a temporary malfunction. If the light does not reset, come by B & M Automotive & Diesel Service in Knoxville and let us fix it.

Q: What are the main problems that cause a throttle control warning light to come on?
A: The five main issues are:
  • Irregular or dangerous unintended acceleration
  • Intermittent loss of throttle control
  • Sudden drop in fuel economy
  • Hesitation or stumbling when accelerating.
  • Engine stuck unable to accelerate beyond a fast idle.
Q: Why is my throttle control warning light on?
A: The connection between the gas pedal and acceleration is controlled by your car's throttle. The amount of acceleration or throttle control is governed by a sophisticated computer system. Any disruption of the electrical signals will affect your vehicle's acceleration and cause the throttle control warning light to come on. If your throttle control light comes on go directly to B & M Automotive & Diesel Service in Knoxville.

Q: Can I drive with the throttle control light on?
A: No, unwanted acceleration may occur and cause an accident. Go straight to the repair shop. There can be many different causes for the throttle control warning light, many are simple fixes.

I really appreciate these guys! After moving from out of state and having a solid mechanic you have trusted for over 14 years, it's like having to find a new doctor too! I am so thankful I found these guys! They have been so helpful and honest every single time! When I first moved here, I worked for UPS using my vehicle out of Oliver Springs. Let's just say that was not good. I've had issues ever since. Going up and down mountains was hard on my vehicle, and unfortunately, my light came on. I knew it was the transmission. I took it in, and they went thru it and told me they would check out everything they could and get back to me. Sadly, it was my transmission. They were super kind, and we decided it would be better to just get another vehicle, and they agreed. I really appreciate their honesty and hard work! Like I told them when I left...I will be back with the new vehicle because I know I found my mechanics for life here in Tennessee!

Pricing was extremely reasonable and everyone was so nice and knowledgeable! I had the A/C compressor in my 2014 Fiat 500L and it's working great!
