Problem 1: Service 4WD System Warning Light On:

The “Service 4WD System” warning light is a common issue for 2007 Jeep Commander owners. It appears on the dashboard to signal an issue with the vehicle’s four-wheel drive (4WD) system. While it is a safety feature for smooth driving, the 4WD warning light would sometimes appear without any reason. Yes, even if the 4WD system is working properly, the Jeep Commander 2007 dashboard will show the warning light, which is a major problem.

Also, different factors can trigger this warning light:

• One primary cause is a malfunctioning transfer case motor. The transfer case motor shifts the vehicle between two- and four-wheel drive modes. If it fails, it can trigger the warning light.
• Additionally, faulty sensors within the 4WD system can contribute to this issue. These sensors monitor various components of the 4WD system, such as wheel speed and differential rotation.
• They relay critical information to the vehicle’s computer system. If these sensors provide inaccurate data or fail, it can lead to a “Service 4WD System” warning.
• Moreover, there can be electrical problems, such as corroded connectors or damaged wiring. It can also result in the warning light illuminating.

Solution To Service 4WD System Warning Light On

The main reason for this problem is the defective transfer case motor. So, remove the skid plate underneath the vehicle to check the transfer case motor. It is located at the rear of the transfer case.

Use a multimeter to test the motor of the transfer case.

• Set the multimeter to DC volts
• Place the probes on the positive and negative terminals of the motor.
• Then, start the engine and shift the vehicle into a four-wheel drive.
• If the motor is working properly, you should see a voltage reading of 12 volts.

If the transfer case motor is not working properly, you will need to replace it.

At times, the warning light may turn on due to faulty 4WD sensors. These sensors include:

• Wheel Speed Sensors,
• Transfer Case Position Sensor
• Differential Rotation Sensor.

You need to remove the wheel and tires to check the speed sensor. You will find it on the rear of the knuckles of your Jeep Commander 2007. For testing the sensor, you should set the multimeter to AC voltage and connect it with the sensors.

We recommend you follow the same steps for checking and fixing the sensors of the transfer case position and differential rotation. Also, you should ensure the 4WD electrical connections are working properly. If there’s any loose connection, tighten it. Also, for rust, clean it with a commercial rust cleaner. It will ensure that the 4WD sensor functions appropriately.

Problem 2: Poor mileage and congested interior:

As an SUV, the 2007 Commander is supposed to have adequate space for comfortable seating. It was frustrating to see that the car didn’t provide enough head and leg space. It was particularly true for the third row.

Even if it was acceptable, even the second row has congested space. It had a length of 4787mm, similar to the older versions. However, many people complained about its uncomfortable seating space. They were dissatisfied with the interior space.

Apart from the seating space and interior room, the SUV needed better mileage. It was introduced with three engine versions. What’s frustrating was that none of these engine versions could achieve 20MPG on average, as Vehicle Story reports.

For a midsize SUV like Jeep Commander, it was more than embarrassing. It was supposed to give 20MPG on highways, but it failed abruptly.

Solution to Poor mileage and congested interior

The 3.7L V6 is a more fuel-efficient engine than the 5.7L V8 that was standard in the 2007 Jeep Commander. If you are looking to improve your vehicle’s fuel economy, you may consider upgrading to the 3.7L V6. Also, you can upgrade to a remanufactured engine for Jeep Commander. These engine upgrades and replacements will cost around $ 3,000 to $ 5,000, on average.

Also, make sure that the Jeep Commander tires are properly inflated. It will improve the fuel efficiency further. According to Tyre Pressure.Com, the front and rear tires of the Jeep Commander should have 35PSI pressure. So, be careful to maintain the optimal tire pressure. 

Since the 2007 Jeep Commander has limited cargo space, you can install a roof rack or cargo box. With it, you can carry more cargo without having to sacrifice passenger space.

Problem 3: Water Leak From Sunroof Drain Tube:

2007 Jeep Commander had issues with water leaking from the sunroof too. It ultimately causes interior damage. It might even promote mold growth within the vehicle’s cabin.

The primary cause of the leak is in the drainage system, specifically the drain tubes of the sunroof. The drain tubes carry rainwater and moisture away from the sunroof. Then, safely direct it to the ground outside the vehicle.

However, over time, these tubes can become clogged or damaged. Debris, dirt, leaves, and other contaminants can accumulate within the drain tubes, obstructing the water flow. Additionally, corrosion can affect the integrity of the drain tubes. It will then lead to cracks or holes that allow water to infiltrate the interior.

Solution to Water Leak From Sunroof Drain Tube

If the sunroof drain is clogged, you must clean the drain tubes. Also, you must regularly remove any debris or obstructions from the drain tubes.

• First, remove the end caps of the tubes.
• You can then use a wire or a pipe cleaner to clear any debris from the tubes.
• Once the tubes are clear, you can replace the end caps.

Sometimes, the sunroof drain tubes are damaged or corroded. You can use a sealant or a patch kit to repair a damaged sunroof drain tube. Apply the patch kit and wait for a couple of hours to let it dry. Also, for the damaged sunroof gasket, apply a sealant to fix it.

Problem 4: Delayed Transmission Engagement:

Many 2007 Jeep Commander owners were furious about the delayed transmission engagement. The drivers found a noticeable lag between shifting gears and the vehicle responding. So, it is frustrating for drivers and affects the vehicle’s performance and drivability.

One primary cause is low transmission fluid levels. When the fluid level is low, it can lead to insufficient lubrication and overheating. It will ultimately result in delayed engagement.

Another potential cause is a clogged transmission fluid filter. The filter is responsible for trapping contaminants and debris. If the filter becomes clogged, it restricts the flow of fluid. Naturally, it will impact the transmission system. It will then delay engagement.

Lastly, a malfunctioning transmission solenoid can lead to delayed engagement. The transmission solenoid regulates the flow of transmission fluid and controls gear shifts. As it malfunctions, it can disrupt the transmission’s normal operation, causing delays and erratic shifting.

Solution to Delayed Transmission Engagement

The transmission fluid level can drop over time due to leaks or evaporation. It can cause delayed transmission engagement.

• To check the transmission fluid level, locate it first. It should be beside the transmission or at the engine bay of a 2007 Jeep Commander.
• Once you locate it, pull the dipstick out and wipe it clean with a rag.
• Then, insert the dipstick and withdraw it again.
• The transmission fluid level should be between the “full” and “add” marks.

If the transmission fluid level is low, add more fluid. You can use the Castrol – Transmax ATF+4 Automatic Transmission Fluid or FRAM – ATF+4 Automatic Transmission Fluid. They both work well with the Jeep Commander transmission system.

Sometimes, the transmission filter may get clogged too. If so, carefully remove the transmission pan. Then, access the filter and unclog it. If it is damaged, simply install a new fluid filter. Also, always ensure that the transmission solenoid is functioning appropriately.

Problem 5: Exhaust Manifold Bolts May Break:

Another irritating 2007 Jeep Commander problem is the breaking down of the exhaust manifold bolts. It will lead to exhaust leaks, decreased engine performance, and increased emissions. It can be costly and detrimental to the vehicle’s safety and functionality.

• The primary culprits behind the broken exhaust manifold bolts are corrosion and rust. These bolts are exposed to high-temperature and high-stress environments. As a result, they can rust over time.
• Harsh environmental conditions can accelerate this corrosion process too. It includes exposure to moisture, road salt, and temperature fluctuations,

When the bolts corrode, they become weakened and are more susceptible to breaking. The broken bolts create gaps in the exhaust manifold gasket. The exhaust gases will then escape before they reach the catalytic converter. It causes a distinct noise of an exhaust leak and a noticeable decrease in engine performance.

Solution to the Broken Exhaust Manifold Bolts:

You should inspect the exhaust manifold bolts regularly and replace any that are corroded or damaged. For inspection, remove the skid plate underneath the vehicle. For rust, try cleaning it with a rust-removal. You can follow the guidelines on rust removal from the Family Handyman since their step-by-step guideline is awesome.

You may also apply a high-temperature anti-seize lubricant to the exhaust manifold bolts. It will prevent the bolts from corroding. Also, ensure that the manifold bolts are torqued to the proper specifications. It protects the bolts from being loose or broken.

Problem 6: Broken Interior Doors at the Handles:

Over time, many 2007 Jeep Commander owners have experienced interior door handles becoming brittle. As a result, it would be prone to breaking or loosening. The broken door handle is frustrating, affecting the ease of entering and exiting the vehicle. On top of it, it compromises the comfort and aesthetics of the SUV interior.

The damage takes place where the door panel meets the handle. Since these are made of plastic, they get damaged soon. The primary causes include:

• The deterioration of interior door handles is attributed to wear and tear. With repeated use, each pull or push emphasizes stress on the handle mechanism.
• The SUV’s handles are also exposed to temperature fluctuations and environmental conditions. They, too, can contribute to the degradation of the materials over time.

Owners have reported that even after taking care of the Jeep Commander like a “Baby”, his issue has occurred. You can mitigate it with gentle use and regular lubrication.

• Solution and fixing tips for the Broken Interior Doors:
• If the interior door handles are broken, you will need to replace them. You can purchase new aftermarket interior door handles and replace the old ones. For it, you will need the following:
• ·         Screwdriver
• ·         Torx bit
• ·         Phillips head bit
• ·         Pliers
• ·         New door handle (if necessary)

Once you have all the tools ready, follow these steps:

• Use the screwdriver to remove the screws that hold the door panel in place.
• Carefully pull the door panel away from the door. If you can’t pull it off, use pliers for the job.
• Disconnect the electrical connectors for the power window switch, door lock switch, and mirror control.
• Use the Torx bit to remove the screws that hold the door handle in place. If the door panel and handle are functioning properly but seem loose, reinforce them. You can reinforce them with epoxy or other adhesives.
• If the door handle is broken, replace it. If the door handle is simply loose, you can tighten the screws and reinstall it.
• For the new door handle, align it properly and ensure that you have connected the wiring and sensor appropriately. Use the Torx bit to tighten the new door handle.

Problem 7: You Select the Cold Function, But Warm Air From the Instrument Panel Outlets Comes Out:

A frustrating problem with 2007 Jeep Commander owners is the warm air from the panel when selecting the cold setting in the HVAC system. 61 Jeep Commander owners have reported this issue with the HVAC system.

Undoubtedly, it causes discomfort for passengers, particularly during hot weather. It is also problematic when trying to cool the cabin quickly.

The primary cause of this issue is a malfunctioning blend door actuator. The blend door actuator controls the position of the blend door. The blend door, in turn, regulates the mixture of hot and cold air that is released into the cabin.

Sometimes, the blend door actuator malfunctions or becomes stuck. Hence, the blend door gets stuck in a position. It will then allow warm air to flow into the cabin even if you have selected the cold setting. It happens due to different issues:

• Wear and tear on the actuator’s gears
• Different electrical issues
• Mechanical failures within the actuator

If you see warm air coming through the HVAC, address it promptly. The key is to maintain the AC and ensure proper functioning of it.

Solution to Warm Air Coming from the Instrument Panel Outlets:

The blend door actuator controls the position of the blend door. The blend door, in turn, regulates the mixture of hot and cold air to release it into the cabin. Use a multimeter to check the voltage and resistance of the actuator.

Do you get warm air even when the blend door actuator works properly? If so, examine the electrical connections. All of the connections should be rust-free, clean, and tight.

Lastly, for the stuck door in the open position, apply lubricant on it. Also, look for any debris that blocks the door and wipe it off with a brush or plier. Finally, tap it with the hammer to help it open and close as it should.

Problem 8: Abnormal Noise From HVAC Blower:

Unusual noises emanating from the HVAC blower are a common concern of the 2007 Jeep Commander, which was in the 2006 model too. These noises include rattling, clicking, humming or squealing, and they can be bothersome to passengers.

Moreover, the noises are indicative of potential HVAC system issues. The most common cause of the noisy HVAC is the debris caught in the blower fan. Also, the failing blower motor causes the issue, too. Over time, dirt, leaves, twigs, and other debris can enter the HVAC system.

It happens when you don’t regularly replace the cabin air filter. Also, the AC may get clogged and noisy when owners don’t clean the intake. With time, debris accumulates in the blower fan. It then creates imbalances and causes the fan to produce unusual noises as it spins.

Another cause for the noisy HVAC system is a failing blower motor. The blower motor generates airflow within the HVAC system. When it begins to wear out or experience electrical issues, it may emit noises such as squealing, humming, or clicking.

Solution to Abnormal Noise From HVAC Blower

Debris buildup on the blower motor and fan blades can cause the HVAC blower to make unusual noises. Hence, you must clean the blower motor and fan blades.

• Remove the blower motor from the vehicle.
• Afterward, use a vacuum cleaner to remove any debris from these components.
• You can also use a brush to clean the motor and fan blades.

A clogged cabin air filter can cause the HVAC blower to make noises too. So, it’s time to replace it. For it, open the SUV’s hood and look at the left side of the engine panel. There, you should find the air filter and replace it. You can get the new cabin air filter for $20 to $50 for the Jeep Commanders. So, the air filter replacement should be affordable.

Lastly, try checking and recharging the freon if the AC is delivering warm air even when turned on. The freon, after recharging, will cool down the air for a comfier ambiance inside the SUV.

Problem 9: Check Engine Light Issues And Different Symptoms:

A sudden message on the SUV’s dashboard for “Check engine light” is a common problem of Jeep Commander 2007. The check engine light issue is accompanied by symptoms such as spark knock, unusual noise, vibration and harshness.

These symptoms can be concerning for owners, which indicate underlying engine or ignition system problems.

• Spark Knock: Spark knock or pinging occurs during combustion. Improper ignition timing, low-octane fuel, carbon deposits in the combustion chamber, or excessive engine heat are all responsible for the knocking noise.
• Unusual Noise: Unusual noises from the engine can be linked to damaged engine components, loose exhaust components, or failing engine mounts. These noises may include knocking, tapping, rattling, or clicking sounds.
• Vibration and Harshness: Vibrations and harshness in the vehicle can stem from worn or imbalanced tires and damaged suspension components. Plus, there can be problems with the drivetrain or transmission. These symptoms can lead to a less comfortable and smooth driving experience.

The illumination of the check engine light can indicate various problems. These are mainly related to the engine or emissions system. Specific diagnostic trouble codes (DTCs) such as P013A and P013C can point to issues with oxygen sensors in the exhaust system. It is critical for monitoring and adjusting the air-fuel mixture for better engine performance and emissions control.

P013A (Oxygen Sensor Slow Response – Rich to Lean, Bank 1 Sensor 2):

The P013A code typically indicates that the downstream oxygen sensor in Bank 1, Sensor 2, is responding too slowly. It happens particularly during the transition from a rich to a lean air-fuel mixture. The main reasons may include faulty oxygen sensors, wiring issues, exhaust leaks, or a rich-running engine.

P013C (Oxygen Sensor Slow Response – Rich to Lean, Bank 2 Sensor 2)

Similar to P013A, the P013C code pertains to the downstream oxygen sensor, but in Bank 2, Sensor 2. It signals a slow response when transitioning from a rich to a lean air-fuel mixture. All these can be mostly attributed to malfunctioning sensors or exhaust system leaks.

Solution to check Engine Light Issues

The check engine light can indicate different problems. Hence, you should diagnose it from a professional mechanic. The mechanic can use a diagnostic scanner to read the diagnostic trouble codes (DTCs) that are stored on the vehicle’s computer. Once the DTCs have been read, the mechanic can diagnose the problem and recommend the appropriate repair.

Problem 10: Safety Concerns and Software Issues:

Some 2007 Jeep Commander owners may receive notifications of Powertrain Control Module (PCM) software updates even when unnecessary. While not immediately evident as a problem, inactive or outdated PCM software causes performance issues and decreased fuel efficiency.

Also, there are six recall issues for safety problems and PCM software.

Manufacturers regularly release software updates to enhance vehicle performance, address known issues, and improve fuel efficiency. The updates may incorporate changes in management algorithms, transmission control, or emission control strategies. However, the update might sometimes go wrong and cause severe problems. For instance, the 2006 version faced the ABS Brake Software problem and even persisted in later models.
