The spark plugs and coil pack were replaced by the dealership, but the problem remained. The Jeep also has a “dreaded tick” and misfire.

💡 Pro Tips:

1. Consult online forums and communities dedicated to Jeep Wranglers to see if other owners have experienced the same cylinder 2 misfire issue in their 2016 models. They may offer valuable insights and potential solutions.
2. Keep detailed records of all repairs and attempted fixes for the misfire issue, including dates, mechanics or dealerships visited, and parts replaced. This will help in building a case with the dealership if further repairs are needed.
3. Consider reaching out to Jeep’s customer service or corporate headquarters to report the issue and inquire if there are any known recalls or technical service bulletins addressing the cylinder 2 misfire problem in the 2016 model year.
4. When dealing with the dealership, be proactive and assertive in requesting a thorough diagnostic process to identify the root cause of the misfire, even if it means running additional tests beyond the computer test. This can help ensure a proper and comprehensive repair.
5. If the dealership is unhelpful or unsatisfactory in their attempts to resolve the misfire issue, it may be worth seeking a third-party opinion from an independent mechanic or automotive specialist who has experience working with Jeep Wranglers. They may provide a fresh perspective and alternative solutions.

1. Initial Belief: Faulty Pentastar Head Issue

When faced with a cylinder 2 misfire issue in a 2016 Jeep Wrangler, one Jeep owner struggled to identify the root of the problem.

Based on their experience and research, they started to suspect that the issue could be related to a faulty Pentastar head, a common problem reported by other Jeep owners. The Pentastar head is a component of the engine that helps regulate the combustion process.

If it malfunctions, it can result in misfires and other performance issues. However, it’s important to note that this initial belief is not confirmed, and further diagnosis is required to determine the exact cause.

2. Out Of Warranty And High Mileage

Adding to the owner’s frustration and concern, their Jeep Wrangler is out of warranty and has already clocked 87,000 miles.

Out-of-warranty repairs can be expensive, making it even more essential to identify the problem accurately. However, the owner discovers a glimmer of hope – their vehicle is still covered under warranty until July 29th.

This means they have a limited time to get the issue addressed at the dealership without incurring substantial costs.

3. Unsuccessful Dealership Repairs: Spark Plugs And Coil Pack Replacement

In an effort to resolve the misfire issue, the Jeep owner took their vehicle to the dealership for repairs.

The dealership initially replaced the spark plugs and coil pack, which can often be the cause of misfires. Unfortunately, this repair work did not solve the problem, and the misfire persisted.

This outcome left the owner frustrated and looking for alternative solutions.

4. Persistent Issues: “Dreaded Tick” And Misfire

On top of the cylinder 2 misfire, the owner also noticed a bothersome “dreaded tick” sound, which could be related to the misfire issue.

This additional symptom adds to the complexity of diagnosing and resolving the problem. The presence of both the misfire and the unusual sound highlights the importance of a thorough inspection and comprehensive diagnosis.

5. Failed Attempt At Diagnosis And Repair By First Mechanic

Seeking a second opinion, the owner brought their Jeep to another mechanic.

In an attempt to diagnose and fix the misfire, the mechanic replaced the spark plug and switched the coil to cylinder 1. This approach aims to determine if the issue lies with the coil or ignition system.

Unfortunately, the problem reoccurred, indicating that the misfire is specific to cylinder 2. This setback only deepened the owner’s frustration, as they were still searching for an effective solution.

6. Seeking Advice And Information For Dealership Visit

With the vehicle’s warranty still in effect for a limited time, the owner plans to schedule a dealership visit for further diagnosis and repair.

However, they are aware that relying solely on the dealership may not yield satisfactory results. To ensure a more informed discussion and comprehensive examination during the visit, the owner seeks advice and information from others who have encountered similar issues with their Jeep Wranglers.

By gathering insights and experiences from fellow Jeep owners, the owner hopes to be equipped with relevant knowledge that will aid in the diagnosis and repair process.

In conclusion, experiencing a cylinder 2 misfire in a 2016 Jeep Wrangler can be a frustrating and perplexing ordeal. With potential issues such as a faulty Pentastar head, out-of-warranty status, and the presence of additional symptoms, a thorough diagnosis becomes crucial.

Despite unsuccessful repair attempts at the dealership and by a separate mechanic, the vehicle’s warranty still provides some reprieve until July 29th. Armed with advice and information gathered from fellow Jeep owners, the vehicle owner can approach the dealership visit with more informed expectations, ultimately working towards a successful resolution of the misfire issue.
