8 Signs Your Car Needs a Professional Mechanic

Tucson Transmission Auto & Diesel Repair in Tucson, AZ Is Here To Help

Is my car broken?

It can be tricky to tell whether your car needs a break or immediate attention from a mechanic. If you notice any of the signs we've listed below, we strongly recommend having your vehicle checked by a professional mechanic sooner rather than later. Taking action early can help you avoid more severe damage and expensive repairs later on.


1. Car Experiences Stalling

Is your car stalling or struggling to accelerate, no matter how hard you press the gas pedal? This isn't just inconvenient-it could indicate serious issues like a failing fuel pump or ignition problems, which are hazardous to face while driving. Don't wait and hope the problem resolves itself. Bring your vehicle in for a check up from our team of experts.


2. Trouble Steering

If your steering wheel becomes difficult to maneuver or your turns aren't as smooth as they used to be, it could signal an issue with essential steering components. Possible reasons could be low power steering fluid or other mechanical failures. It's crucial to address any problems that impact your ability to steer the car safely-seek immediate professional assistance at an auto repair shop.


3. Fluid Leaks

If your vehicle is leaving behind puddles of liquid, it's a sign you should investigate further. While water from air conditioning condensation is usually harmless, other fluids like oil, transmission fluid (red or brown), coolant (blue, yellow, green), power steering fluid, or brake fluid (thick but clear) indicate a potential leak in one of your car's critical systems. Addressing these leaks promptly can prevent further damage and ensure optimal performance. It's advisable to have these issues inspected and remedied by a specialist.


4. Worn Out Brakes

Brakes naturally wear down over time and if you notice them losing effectiveness or making unusual noises, it's a sign they may need attention. Screeching or squealing often indicates that the brake pads are worn and require replacement. Additionally, if your brakes shake or vibrate, this could point to a range of issues, from further wear on the pads to problems with the brake fluid or alignment.


5. Alignment Issues

If you've noticed your car's ride has become notably less smooth in the past few months, it might be time for a trip to the auto shop. A shaky or vibrating ride, especially at higher speeds, often stems from wheel or alignment issues.

Even after a proper wheel alignment, wheels can gradually shift, influenced by normal wear and tear or sudden incidents like accidents or unexpected bumps. Realignment is a straightforward procedure that can swiftly address the issue.


6. Uncommon Engine Noise

Engines are meant to run smoothly, so if yours starts to sound louder with age, that's normal. But if you hear sudden, unusual noises like grinding, popping, or growling-or if starting your engine becomes a struggle-it's a good idea to visit your local auto shop. Catching these warning signs early can help ensure your car stays in top shape!


7. Diagnostic Lights

Modern vehicles are equipped with engine diagnostic or check engine lights that sometimes activate not because of an immediate issue, but as reminders for routine checkups after a certain mileage has been reached.

In some instances, a glitch in the car's computer system might even trigger these lights without any actual problem. However, when these lights come on alongside other symptoms such as poor performance or strange noises, it's wise to get your car checked by a professional to ensure everything is running smoothly.


8. Unpleasant Exhaust

If you notice your exhaust emitting black smoke or strange odors, it might be time to check in with a mechanic. This could indicate something like a clogged filter or another issue with your car's systems, possibly even the catalytic converter. It's always a good idea to get these things looked at to keep your car running smoothly.

We are extremely satisfied with Tucson Auto and Diesel! My husbands truck was pretty much dead and Josh the owner contacted us through Facebook and got us in the very next day! We had some trouble getting our truck there, but nonetheless we got it there. We expected our truck to be out for a couple days considering we had just dropped it off, and they got it back to us the same exact day! If I could recommend anyone to go anywhere for their trucks it’s this place! 10/10 experience!

Holy Cow! This place knocks it out of the park. Super friendly staff especially the greeters at the front desk. The cost for my KIA Transfer Case replacement was very reasonable compared to the "crooks" at Royal KIA service department. I will be going back here for sure, highly recommended.
