2018-2020 Nissan Frontier Exhaust System Leak Loud Ticking or Hissing Noise From the Engine Bay lemon lawyer attorney
Affected Years: 2018, 2019, 2020 Nissan Frontier. Our law firm is also investigating 2021, 2022, 2023, 2024, 2025, 2026 Nissan Frontier for the same issues.

These issues seem to arise from defects in the Exhaust Manifold/Gasket.

The pickup truck is more than 100 years old now, with the Model T Runabout first being offered in 1925. There have been many changes in the last 30 years as compared to the first 70 years. There are many differences that are present, but there are still quite a few things that remain exactly the same. The gasoline engine still powers most of the pickups sold today, though that is certainly changing. With that engine comes the need and importance of maintaining it, and while this is mostly the same as it’s always been, the function has evolved in a similar fashion to many of the supporting systems on trucks like steering and braking, with pumps and electronics. When it comes to the function of an internal combustion engine, items like exhaust have changed a bit. The heat that engines today create is one. When you develop issues with cooling or airflow, the engine begins to make some notably loud sounds like ticking, hissing, or knocking. This is telling you that you have some kind of problem that is certain to need repairing.

When you have an issue with your Nissan Frontier pickup, you call your dealer to get it scheduled when you have a warranty. Despite several attempts to get it fixed, it isn’t functioning properly, and your pickup keeps making unusual sounds. You may be thinking you have a Lemon Law issue with your vehicle. If this happens, we want you to call the team at Guardian Lemon Law. We will schedule a consultation, and if hired, complete a review of your case as soon as possible to verify that it does qualify under California Lemon Law. If so, we will review the options available to you. We have an experienced Nissan Frontier lemon law attorney that we can assign to your case if it is time to file a claim or bring a lawsuit.

The first thing to do is to file a claim with the manufacturer. This lets them know you are serious about getting this resolved. If that doesn’t get the resolution you are looking for, then we can assign a Nissan Frontier exhaust system leak noise lemon lawyer and begin talking about how we can sue Nissan for selling you a defective, lemon Frontier pickup.

California Lemon Law And The Basics – Solutions And Resolution

The Lemon Law exists to protect consumers from manufacturers who are not honoring their express warranties. In this case, it holds Nissan accountable for the remedy when they fail at repairs. Lemon Law in California begins with having a vehicle that qualifies, and an issue that is covered by the factory warranty, where repair attempts have been made and have failed repeatedly. The next step is to examine the issue itself and verify that it also meets the criteria for a Lemon Law claim. The third part of the evaluation is verifying that you are within the time limits set forth under the Lemon Law to bring a claim or file suit. Once qualified, we know that we can sue Nissan for selling you a defective, lemon Nissan Frontier pickup.

What it will give you is the option to either have Nissan perform a vehicle buyback, which is comparable to a refund of what you paid plus fees, or to make a replacement vehicle available to you that is equal in value or in make and model, if available. Don’t hesitate to contact Guardian Lemon Law when you need a Nissan Frontier exhaust system leak lemon law lawsuit filed on your behalf. We will help you determine whether your vehicle meets the qualifications.

The Qualifying Requirements And Time Limits To File A Lemon Law Claim in California

Once hired, our initial task will be to complete the case evaluation. In that process, our first step is to qualify your vehicle. The first three requirements listed below have to be met.

  • The vehicle is still covered under the manufacturer’s new car warranty or a certified pre-owned warranty when the issue first occurred, as well as during each repair effort
  • The issue cannot be caused by improper use or abuse of the vehicle, either before initial repairs or after repairs have begun
  • The manufacturer has made a reasonable number of attempts to fix the issue with the vehicle. This is defined as a minimum of 2 tries for any significant issues affecting the safety or use of the vehicle, or 4 efforts for any defect that is not related to anything safety-related

The next set of qualifications concerns the repair specific to your vehicle and the effort made by the dealer or manufacturer representative to fix the issue. Only one of these needs to be met to qualify, but meeting more of them is desirable.

  • All efforts of repair for the specific issue have totaled more than 30 days, with the vehicle unavailable to you during that time period
  • The issue being repaired directly impacts the safety, use, or value of the vehicle

The final step is to verify that the Statute of Limitations has not expired on your claim. The set time limit has two definitions, and the one that applies is the earliest of the two. A claim or suit must be filed within one year of the original factory warranty expiring for the vehicle. The second definition is six years from the date of vehicle delivery by the dealer to you.

If the requirements above are met, the next step is to assign an experienced lemon lawyer to sue Nissan for the exhaust system leak.

2018-2020 Nissan Frontier Pickup Engine Bay Noises Like Ticking Or Hissing

A loud, rhythmic ticking or hissing from your Frontier’s engine bay is generally going to point to an exhaust manifold leak. As the exhaust metal heats and expands, the gap closes,, and the noise often quiets down. Other possibilities for some of the sounds will include noisy direct injectors or the high-pressure fuel pump.

The common symptoms of this issue are:

Ticking during cold starts will be when the noise is most audible. It will sound like a fast, rhythmic ticking or tapping that speeds up as you press the accelerator

The noise will fade after a few minutes of driving. The metal expands and seals the leak or crack area, which will significantly reduce or perhaps even completely silence the ticking. You might smell raw exhaust under the hood or inside the cabin when the leak is fresh

The primary causes of this problem include:

  • The gaskets sealing the manifold to the engine block or downpipe can degrade or blow out, leading to the hissing sound early on
  • A cracked exhaust manifold is often caused by excessive temperature fluctuations. The resulting metal fatigue will frequently cause a hairline crack to develop on the manifold. This is particularly common on the passenger side or driver’s side, where heat is notably higher in the engine bay during engine use
  • A failed catalytic converter could also be the issue because it is integrated into the exhaust manifold assembly on later Frontier V6 models. What this means is that it could be the cause of the manifold cracking, and as such, the entire manifold requires replacement

It is very important to have the dealer document the noise source, particularly if the dealership suspects a leaking manifold. If your dealer cannot permanently repair the issue behind the noises, then it is time to talk to Guardian Lemon Law.
