The most common reasons a 2024 Kia Telluride has rough idle are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil.
  • Spark Plugs: Worn or fouled spark plugs can lead to misfires, poor fuel economy, and difficulty starting the engine.
  • Ignition Coil: A faulty ignition coil can cause misfires, rough idling, and difficulty starting the engine due to inadequate spark delivery to the spark plugs.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2024 Kia Telluride has rough idle?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

Brake caliper failure occurs in two different ways, and they create different symptoms.

The caliper can become stuck, in which case it won't release the brake pads. The seized caliper will cause the vehicle to brake constantly on one side, forcing the car to move toward that side. This pulling will be accompanied by a strong odor from one wheel.

Another way calipers fail is by leaking. If the caliper leaks, the brake pedal will feel too easy to push, and will sink all the way to the floor when held. Braking will become less effective the longer this goes on. There may also be brake fluid leaking onto the wheel.

Here are a few common symptoms of worn-out brake pads:

  1. Low brake pad warning light is on: Not all vehicles are equipped with this system, but if yours is, this dashboard indicator light will likely be the first signal it’s time to replace your brake pads.
  2. Brakes start to squeal regularly: This is often one of the first signs of worn brake pads and is caused by a metallic piece built into brake pads for this exact purpose. This part contacts the brake rotor to make a squealing or whining noise when the pads are low.
  3. Brakes make loud grinding noise: If not addressed early enough, your brake pads may get so worn that the metal backing plate of the pad grinds against the metal rotor.
  4. Brake pads look thin: You may be able to visually check your brake pad thickness to determine if they need replacement.

Brake rotors are mainly maintenance free, but when they have been subjected to abnormally hard use, the heat they absorb can cause the metal to turn blue, and cracking to occur. When this occurs, customers often specify they have lost braking power, or the vehicle's brakes are making noise. There may be no symptoms at all related to changing the brake rotors, since it is recommended to change brake rotors on most modern vehicles when performing a standard brake service.

Most often, a brake system inspection will just be a routine portion of manufacturer specified maintenance, and will be performed at mileage intervals. In those cases, there will likely be no symptoms. However, when a brake system makes a funny noise, causes vibration, is hard to use, will not slow the vehicle, prevents the vehicle from driving, makes the vehicle pull to one side, or leaks brake fluid, the vehicle will need a visit dedicated to the inspection of the brake system.

What are the initial diagnostic steps to take for a rough idle in a 2024 Kia Telluride?

When faced with a rough idle in your 2024 Kia Telluride, start by checking the spark plugs, as they play a crucial role in engine performance. Worn or faulty spark plugs can lead to misfires, resulting in an uneven idle. Next, inspect the air filter; a clogged filter can restrict airflow, negatively impacting engine efficiency. If these components appear to be in good condition, turn your attention to the fuel system. Ensure that the fuel injectors, fuel filter, and fuel pump are functioning properly, as any issues here can contribute to rough idling. Utilizing an OBD-II scanner is also beneficial; it can reveal error codes that indicate specific problems within the engine. Additionally, examine the throttle body for dirt or carbon buildup, which can hinder airflow and affect engine performance. Lastly, check for vacuum leaks in hoses and connections, as these can disrupt the air-fuel mixture and lead to an unstable idle. By systematically addressing these areas, you can effectively diagnose and potentially resolve the rough idle issue in your vehicle.

What are the common causes of a rough idle in a 2024 Kia Telluride?

When dealing with a rough idle in your 2024 Kia Telluride, it's crucial to understand the common problems that could be at play. One of the primary culprits is a dirty or clogged air filter, which can significantly restrict airflow to the engine, leading to performance issues. Additionally, faulty spark plugs are notorious for causing misfires, which can manifest as a rough idle. Another potential issue is vacuum leaks; these can disrupt the delicate air-fuel mixture necessary for smooth engine operation. Fuel system problems, such as clogged fuel filters or injectors, can also hinder engine performance and contribute to rough idling. Furthermore, a malfunctioning oxygen sensor can throw off the air-fuel ratio, exacerbating the issue. Lastly, don’t overlook ignition system problems, including faulty ignition coils or distributors, as they can also lead to an uneven idle. Addressing these issues promptly is essential for maintaining the performance and efficiency of your vehicle, and if the problem persists, consulting a qualified mechanic is advisable for a thorough diagnosis.

How urgent is it to address the rough idle in my 2024 Kia Telluride?

Addressing a rough idle in your 2024 Kia Telluride is crucial for maintaining the vehicle's performance and longevity. Ignoring this symptom can lead to a cascade of problems, including decreased fuel efficiency and increased emissions, which not only impacts your wallet but also the environment. A rough idle may indicate underlying issues such as dirty fuel injectors or a clogged air filter, which, if left unresolved, could escalate into more severe engine damage. Promptly tackling this issue not only helps in preserving the health of your engine but also prevents costly repairs down the line. Regular maintenance and timely intervention are key to ensuring your vehicle operates smoothly and efficiently, making it essential to address any signs of a rough idle as soon as they arise.
