The most common reasons a 2013 Jeep Compass has a vacuum leak are leaking vacuum hoses, leaking gaskets and seals, or bad actuators and valves.
  • Leaking Vacuum Hoses: A cracked or disconnected vacuum hose can lead to a loss of engine vacuum, resulting in poor engine performance and increased fuel consumption.
  • Leaking Gaskets and Seals: Aged or damaged gaskets and seals can lead to fluid leaks, resulting in loss of engine oil or coolant and potential engine damage.
  • Bad Actuators and Valves: A malfunctioning actuator or valve can disrupt the proper operation of the vehicle's systems, leading to issues such as poor engine performance or erratic behavior of components like the HVAC system.
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 2013 Jeep Compass has a vacuum leak?

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.

Problems with the intake manifold gasket can create the following symptoms:

  • Illuminated check engine light
  • Erratic engine performance
  • Oil and coolant leaks
  • Poor gas mileage
  • Stalling

Rough idling, lack of power, engine oil leaks, engine burning oil, and illumination of the check engine light are all possible if the PCV valve has clogged. If the check engine light comes on, the on-board diagnostics (OBD) trouble codes will most likely relate to manifold vacuum, air and fuel mixture, PCV system, mass airflow sensor readings, and exhaust and emissions readings. These are all affected in the event the PCV valve is clogged, is stuck fully open, or is stuck fully closed, however, if the valve is stuck fully open, the engine oil seals are not in danger of overpressure.

A bad valve cover gasket will result in an oil leak. You may notice oil under the car or on other parts under the hood. You might also notice a burning smell while driving.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

What are the steps to diagnose a vacuum leak in a 2013 Jeep Compass?

To effectively diagnose a vacuum leak in your 2013 Jeep Compass, start with the simplest methods before progressing to more complex diagnostics. Begin by listening for any unusual sounds, such as hissing or whistling, which can indicate a vacuum leak. Next, utilize an OBD2 scanner to check for error codes; codes like P2173 can specifically point to intake leaks. After that, visually inspect the vacuum hoses for any signs of wear, cracks, or disconnections, as these are common culprits. Additionally, examine gaskets and valves, which can also contribute to leaks. For a more hands-on approach, spray carb cleaner around suspected leak areas while the engine is running; a change in RPMs can confirm the presence of a leak. If these methods do not yield results, or if you feel uncertain about your findings, it may be wise to consult a professional mechanic for a thorough inspection. This systematic approach will help you efficiently identify and address any vacuum leak issues in your vehicle.

What are the common problems associated with vacuum leaks in a 2013 Jeep Compass?

When tackling vacuum leaks in a 2013 Jeep Compass, it's crucial to be aware of the common problems that can lead to this issue. One of the primary culprits is leaking vacuum hoses, which can deteriorate over time due to heat and wear, resulting in air escaping from the system. Additionally, gaskets and seals may also fail, particularly around the intake manifold or throttle body, allowing unmetered air to enter the engine. Another potential issue lies with bad actuators and valves, which can malfunction and disrupt the vacuum system's operation. Identifying these problems early is essential, as they can lead to poor engine performance, increased fuel consumption, and even stalling. By understanding these common failure modes, DIYers can effectively diagnose and repair vacuum leaks, ensuring their Jeep Compass runs smoothly.

How urgent is it to address a vacuum leak in a 2013 Jeep Compass?

Addressing a vacuum leak in a 2013 Jeep Compass is not just a matter of routine maintenance; it is a critical task that demands immediate attention. Ignoring a vacuum leak can lead to significant engine performance issues, such as erratic RPMs and sluggish acceleration, which can compromise your driving experience and safety. Additionally, systems that rely on engine vacuum, including power brakes and steering, may become less effective, posing further risks while driving. The longer you wait to fix a vacuum leak, the more likely you are to encounter escalating problems, including potential damage to the engine and its components. By taking the initiative to diagnose and repair a vacuum leak promptly, you can ensure your vehicle operates smoothly and efficiently, ultimately saving you time and money in the long run. For DIY enthusiasts, understanding the urgency of this issue is crucial, as timely intervention can prevent more extensive repairs down the line.
