Jeep Renegade Ignition Coil Problems

Whether navigating city streets or tackling rough terrain, a persistent ignition coil problem can significantly diminish the enjoyment of owning a Jeep Renegade. 

In addition, these issues often require costly repairs and frequent visits to the dealership or mechanic, leading to increased maintenance expenses and inconvenience for owners. Some of the common ignition coil problems are discussed below:

Random Misfire with No Codes

One challenge frequently encountered with the ignition coils in Jeep Renegade vehicles is the occurrence of random misfires without triggering any error codes. 

While engine misfires typically result in the activation of the P0301 error code, this particular issue can be vexing due to its sporadic nature and lack of accompanying trouble codes.

Drivers often report experiencing a noticeable stutter during idling or while cruising at lower speeds. This symptom can be indicative of an underlying ignition coil malfunction, potentially leading to performance issues and decreased fuel efficiency.

This issue often stems from faults within the ignition coil system, which can lead to irregular sparks and combustion. The lack of an error code complicates diagnosis and troubleshooting efforts for technicians and owners alike. 

In some cases, the misfire may be more prominent under specific driving conditions, such as when cruising at reduced speed or during stop-and-go traffic.

Sputtering at Idle

Numerous Jeep Renegade owners have reported persistent issues with sputtering during idle and acceleration, indicating potential problems with the engine’s performance. Furthermore, many drivers have experienced jolting or kicks from the transmission when traveling at speeds between 25-30 mph, leading to a sense of unease and discomfort while driving.

Additionally, some users have expressed concerns about the vehicle shaking violently at speeds exceeding 65 mph, which can significantly compromise road safety and stability. However, initial attempts to resolve these issues through the replacement of components such as the ignition coil, throttle body, and spark plugs have shown promising results in mitigating symptoms.

Further investigation into the root cause of these malfunctions is necessary to ensure long-term reliability and overall driving satisfaction for Jeep Renegade owners.

Bad Ignition Coil in 2017 Jeep Renegade

A user recently posted on Carproblemzoo about experiencing a bad ignition coil in their 2017 Jeep Renegade. The faulty ignition coil has been causing the vehicle to unexpectedly break down while the user was running errands in town. This issue poses a significant safety and reliability concern for the driver as well as for others sharing the road.

The 2017 Jeep Renegade has a standard 1.4L turbocharged engine, which relies heavily on an efficient ignition system for optimal performance and smooth operation. A malfunctioning ignition coil disrupts this critical process, leading to misfires, loss of power, and, ultimately, unexpected stalling.

Given that the vehicle is relatively new, this problem speaks to potential manufacturing or quality control issues within the ignition system that demand attention from both the manufacturer and authorized service centers. 

Remedying this issue will likely involve diagnosing and replacing the faulty component with a reliable replacement unit and thorough testing to ensure its long-term functionality and overall safety on the road.

Ignition Isn’t Turning On

Several Jeep Renegade owners have reported issues with their vehicle’s ignition not turning on, leading to frustration and inconvenience. 

In addition, there have been complaints of emergency lights failing to function as intended, causing concern for driver safety in emergency situations. These issues are indicative of a potential electrical system malfunction within the vehicle.

Given the nature of these issues, affected Jeep Renegade owners are encouraged to contact their authorized dealerships or certified auto repair shops for thorough diagnostics and repairs. 

How to Troubleshoot and Fix Ignition Coil Issues in Jeep Renegade

It is now the opportune moment to shift our attention toward addressing the challenges associated with ignition coil malfunctions in the Jeep Wrangler. Let us delve into a systematic, detailed approach to resolving this issue.

How to Fix Ignition Coil Issues in Jeep Renegade

Before jumping to replace the ignition coil in a Jeep Renegade, it’s essential to take some preliminary steps to identify and potentially fix any issues with the existing component. Start by inspecting the spark plugs and wires for signs of damage or wear, as these can contribute to ignition coil problems. 

Next, check for loose or corroded connections around the ignition coil and associated components, ensuring that all connections are secure and clean.

Moving on, perform a diagnostic scan using an OBD-II scanner to retrieve any error codes related to the ignition system. This can provide valuable insight into potential underlying issues that may be causing the ignition coil malfunction. Additionally, test the ignition coil using a multimeter to measure its resistance and ensure it falls within the manufacturer’s specified range.

Further troubleshooting involves checking for any air or fuel delivery problems that could be affecting engine performance, as these issues can sometimes manifest as symptoms similar to those of a faulty ignition coil. Finally, consider cleaning or servicing other relevant components, such as the throttle body and fuel injectors, before pursuing an outright replacement of the ignition coil.

Steps to Remove and Replace Ignition Coil

First, start by disconnecting the car battery’s negative terminal to ensure safety during the process. Next, locate the ignition coil in your vehicle’s engine compartment and carefully remove any components that might obstruct its access. 

Once you have clear access, use a socket wrench or screwdriver to loosen and remove the bolts securing the ignition coil in place. Finally, gently disconnect the electrical connectors attached to the ignition coil before removing it from its mounting location.

As you prepare to install a new ignition coil, take note of any specific guidelines provided by the manufacturer and handle this crucial component with care. Once you’ve positioned the new ignition coil in place, securely fasten it with bolts and reattach all electrical connectors in their appropriate positions.

Remember to finally reconnect the car battery’s negative terminal before testing out your Jeep Renegade with its newly replaced ignition coil. 

Final Words

Jeep Renegade ignition coil problems are a serious issue that can impact the vehicle’s performance and reliability. Owners should be aware of the potential symptoms, such as engine misfires, loss of power, and rough idling, and seek professional diagnosis and repair if they experience these issues. 

It is crucial for Jeep to address these problems promptly through effective communication with affected customers and implementing appropriate solutions to prevent further complications.
