The Mazda CX-9 Life Expectancy

A Mazda CX-9 should typically range between 200,000 and 250,000 miles, which is a good number for mid-sized SUVs if you travel 15,000 miles yearly because they will last at least 13 and slightly longer than 16 years.

Variable Valve Timing and Stretched Timing Chains

Mazda's L-series engines are earning a reputation for variable valve timing (VVT) defects that can cause oil leaks, excessive smoke out of the tailpipe, loose timing chains, and catastrophic engine failure.

The 2023 Mazda CX-9 is being discontinued —although being replaced is more the case. Coming next year is the new flagship vehicle from Mazda. The CX-90 will replace the CX-9 in the Mazda SUV lineup.

First, open the hood and start the car. While the engine is running, remove the negative cable from the battery. If the vehicle stalls or dies, the alternator is likely bad. This happens because the alternator is not generating enough electricity to keep the engine running on its own.

Alternators have an impressive lifespan of seven years–or between 80,000 to 150,000 miles. But be careful that you are not wearing it out prematurely!

You should leave your traction control at all times so that you can benefit from this important safety feature. However, in very rare circumstances, you may need to turn the traction control off temporarily.

Should I have TCS on or off? ›

It's important to keep traction control on 99% of the time when you're driving. However, there are some cases where the safety feature could do more harm than good. For example, it's better to keep it off if you get stuck in the mud, sand, or even snow.

A failing wheel speed sensor, or damages in its wiring, disrupts the connection between the wheel and TCS computer. This prevents the TCS working on that wheel, so the light will illuminate and stay lit until addressed. It may even turn on a “TCS off” light to indicate the system is not functioning.

One of the most common problems you're likely to experience with an alternator is a failure in the bearings. There are needle bearings in the alternator that allow the rotor to freely spin inside the housing, and those bearings can break down over time as a result of exposure to heat and dirt.

Your car's onboard computer will cut the power to non-vital accessories when the alternator is not producing enough electricity. You will notice several issues at once. For instance, the windows will operate slower, the sunroof will get stuck, and the heated seats will not work as they should.

If you have a “Check Engine" light on, connect a code reader to the diagnostic port. If you find code P0562, you very likely have a failing alternator (note that codes may vary by vehicle make/model/year). Get it checked out before it fails entirely.

Jumpstart your car. If you can turn the engine on, but it dies shortly thereafter, your car alternator likely isn't able to charge the battery. On the other hand, if you jumpstart the car and later on it fails to start on its own, it's likely a dead battery.

The charging system warning light on the dashboard will likely illuminate if the alternator fuse is blown. A blown alternator fuse can also trigger the check engine light and many other dashboard warnings due to system undercharging.

“With the car running, you can turn on all the heavy loads; turn on the heater blower motor, turn the lights on, etc.,” he tells us. “Then check the voltage at the battery terminals. That'll give you a general idea of the health of the alternator.”

Most of the time, alternators fail as a result of age or use. However, some other factors can cause an alternator to fail prematurely. Fluid leaking on the car alternator can commonly lead to failure. Often, engine oil or power steering fluid can work its way into the alternator and cause it to malfunction or fail.

What happens when alternator stops working while driving? The car tends to slowly lose power if the alternator has gone bad while the car is being driven. You'll notice the headlights start to dim shortly before the car loses power and dies.

Alternator issues won't go away on their own. They'll need to get fixed eventually, and if you wait too long, the issues might become more serious, leading to more expensive repairs and higher bills for you to pay. If you get the issue fixed early on, the repair will usually be much simpler and cheaper.

What causes traction control to malfunction? ›

Traction control and ABS most commonly develop problems with the wheel speed sensors. These sensors are moderately exposed to the elements, leaving them slightly vulnerable. The magnetic operation on the traction control sensors or Anti-lock Braking sensors can be interrupted by dirt or other buildups.

Traction control system switch: Traction switch replacement may cost around $111 to $125. This includes labor charges ($56 – $71) and spare parts ($54). Wheel speed sensor: The estimated cost of wheel speed sensor replacement is around $208 to $250, including labor costs ($62 – $78) and parts ($146 – $177).

Recommended Services. The vehicle's shaking may be caused my improper signals going to the traction control system and in return the traction control system is trying to correct a problem based off of improper signals.

About 23% employees (from the 4,600+ responders) think that TCS is a brand that can help them boost their career. Another important factor that lures the workforce towards TCS is the company's work environment. About 16% of employees voted TCS for providing a favourable and healthy work environment.

In some cases, the warning light may come on because wheel-speed sensors are covered with road grime or debris. When the traction control warning light stays on, that means you aren't getting any help from the system to control traction and the system needs to be checked.

In some vehicles it is located under the hood and/or is a part of the ABS control module. Other vehicles may have the traction control module located in the interior or trunk areas.

Common signs include the Traction Control System (TCS) Light coming on, TCS not turning off/on, and loss of TCS or ABS features.

Traction Control System (TCS)

This means that on a slick surface, the engine adjusts automatically to provide optimum power to the drive wheels, limiting wheel spin and loss of traction. A system malfunction or operation conditions are indicated by a warning.

The traction control system (TCS) detects if a loss of traction occurs among the car's wheels. Upon identifying a wheel that is losing its grip on the road, the system automatically applies the brakes to that individual one or cut down the car's engine power to the slipping wheel.

Brake issues have been the number one complaint about the Mazda CX-9 across all-year models.

Does Mazda CX-9 need premium gas? ›
