Affected Years: 2020, 2021, 2022, 2023, 2024, 2025 Ram 3500 Pickup. Our law firm is also investigating 2026 Ram 3500 Pickup for the same issues.
These issues seem to arise from defects in the Engine Internals.
The pickup truck vehicle is 101 years old, with the Model T Runabout first being offered in 1925. With the advent of modern technology, there have been a great many changes in the last 30 years as compared to the first 100 years. For as many differences that exist, there are still quite a few things that remain exactly the same. The number of wheels is still 4, and the pedals and steering wheel are still the same. The gasoline engine still powers most of the pickups today, though that is certainly changing. With that engine comes the need and importance of maintaining it, and while the actual methods are still similar, the function has evolved in a similar fashion to many of the supporting systems on trucks, like steering and braking. When it comes to the function of an internal combustion engine, lubrication and cooling are key when it comes to having that engine perform reliably. When you develop issues with either system, the engine begins to make some notably loud sounds, like knocking, telling you that you have some kind of problem that is certain to be a challenge to repair.
When you have an issue with your Ram 3500 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 review of your case as soon as possible and see if it does qualify under California Lemon Law. If so, we will review the options available to you. We have an experienced Ram 3500 pickup 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. If that doesn’t get the resolution you are looking for, then we can assign a Ram 3500 pickup engine noise lemon lawyer and begin talking about how we can sue Ram for selling you a defective, lemon 3500 pickup.
How Does California Lemon Law Work For Me, and What Does It Give Me?
Lemon Law exists to protect consumers like you from manufacturers who cannot honor their express warranties. In this case, it holds Ram accountable for some remedy for you 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. 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 Ram for selling you a defective, lemon Ram 3500 pickup.
What it will give you is the option to either have Ram 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.
The Eligibility Requirements And Time Limit To File A Lemon Law Claim
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 deals with 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 will be better.
- 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 time limit has two terms, 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, or six years from the date of vehicle delivery. If the requirements above are met, the next step is to assign an experienced lemon lawyer to sue Ram for engine noise.
2020-2025 Ram 3500 Pickup Engine Noise Like Knocking And Rattling Noises Issues
The loud knocking or rattling from 2020-2025 Ram 3500 pickups with the 6.7L Cummins diesel is often attributed to issues such as high-pressure fuel pump (HPFP) failures, injector knock, or more severe internal failures like rod bearings. For the diesel, the issues might be caused by any of the following:
- High-Pressure Fuel Pump (HPFP) Failure
- Injector Knock/Rattle
- Spun Rod Bearings
- Heater Grid Bolt Failure
- Exhaust/Turbo Issues
- For 6.4L Hemi models, similar noises are often caused by lifter failure or piston slap:
- Lifter Failure (“Hemi Tick”)
- Piston Slap/Knock
- Exhaust Manifold Leak
If the truck is still under the manufacturer’s warranty, it is very important to have the dealer document the noise source, particularly if the dealership suspects the issue to be a 6.7L HPFP or a 6.4L lifter issue, as these can lead to catastrophic failure and require a full engine replacement to become functional again.
The leaks of critical fluids can occur at any point, including the block itself. The hoses and connections, as well as the reservoir used for overflow, should be examined. The radiator and the pump are going to be the critical parts, but there are many other smaller components that are just as important to healthy operation. The pressure relief valve and sensors will all play an important role in the continued operation of the system as well. Oftentimes, leaks in the pressurized systems begin in part because the pressure relief valve did not work, leading to overpressurization.
Most repair efforts begin with examination of the components, and hopefully, they will generally tell the mechanic what needs to be repaired. It seems only after a couple of failures of the same part does interest rise in the part failures. If your dealer cannot permanently repair the issue behind the knocking, then it is time to talk to Guardian Lemon Law about hiring a lawyer experienced in lawyer experienced in Ram 3500 pickup engine noise lemon law cases to represent you.
