FAQs About Automobile Squeaks, Squeals and Rattles
Why is my car making a squealing noise?
It may be a slipping fan belt. Listen for warning signs such as squeaking or chirping noises. These sounds are often caused by misalignment between the belt and pulley. If you come by Serious Fleet & Automotive in Mesa, our professional auto repair technicians can inspect and realign the belt to stop the noise and address the problem before the belt fails completely.
Why does my car make a noise when I turn the steering wheel?
If your car makes strange sounds or clicking noises when you turn the steering wheel, one possible cause is low power steering fluid. When the fluid level drops, air can enter the power steering system and cause unwanted noises.
Come to Serious Fleet & Automotive to have the power steering system inspected and the fluid level checked. If the noise returns quickly after the fluid is topped off, your vehicle may have a power steering fluid leak. Our professionals in Mesa can diagnose the cause and recommend the appropriate repair.
Why does my car squeal when I start it in the morning?
A squealing noise when starting your vehicle can be caused by a worn or loose belt. Depending on the vehicle and the source of the noise, the issue may involve an accessory drive belt or another belt-driven component. Because some belt failures can lead to serious mechanical problems, unusual or persistent noises should be inspected promptly. Come to Serious Fleet & Automotive and our technicians can determine the source of the noise and recommend the proper repair.
Leaking Fluid FAQs
Why is water leaking on my foot on the driver's side?
The most common cause is a blocked air conditioning drain hose. This is typically a straightforward repair at Serious Fleet & Automotive. Other possible causes of water leaking onto the driver's side floor include a damaged door seal or a leaking heat exchanger. Our technicians can inspect the source of the leak and determine the appropriate repair.
What should I do if my car creates a small oil leak on my driveway?
If the spill is still wet, cover the stain with an absorbent material such as clay cat litter, sand, cornmeal, cornstarch, or baking soda. This can help absorb the oil before it soaks further into the concrete. Once the spill has dried, sweep up the absorbent material and clean the remaining stain with soap and water.
A small oil leak on your driveway is also an indication that something may be wrong with your vehicle. Bring your car to Serious Fleet & Automotive so the source of the leak can be diagnosed. An oil leak should not be ignored because loss of engine oil can eventually lead to serious engine damage.
Why is my car leaking a sweet-smelling fluid?
If you notice a sweet-smelling fluid leaking from your vehicle, coolant or antifreeze may be the source. A coolant leak can become a serious problem if left unaddressed. If the coolant level becomes too low, the engine may overheat and potentially suffer engine damage. Have the vehicle inspected promptly to locate and repair the leak.

What Our Customers Are Saying
I had my AC fixed, new pump and charge worked for two days and had a pump failure. Called back and had a conversation with Brad about the problem. He went above and beyond to take care of me and my family with zero delay. I can't recommend this shop enough. My family and I were more than comfortable in their beautiful waiting room. As a female it was nice waiting in a shop that was so clean and professional. I've been in lots of shops that smell like the cars they are working on. Not this shop, its extremely well maintained and every single employee is kind and professional. I would never dream of going to another shop after my experience here! Customers for life. Thank you Bradley and your team!

Had what I thought was front end trouble. Took it into Serious Fleet and Auto to see what the problem might be. They found that I had the tread peeling off a couple of tires. They said it was lucky I made it to the shop. I left it in their hands and had four new tires put on and picked it up when they were done. I've used them in the past and they've always been straight forward and very thorough. I consider them my go-to shop.
