Affected Years: 2016, 2017, 2018, 2019, 2020 Porsche 911. Our law firm is also investigating 2021, 2022, 2023, 2024, 2025, 2026 Porsche 911 for the same issues.
These issues seem to arise from defects in the Engine Lifters/Valvetrain.
The sports car is 116 years old, with the Benz Prinz Heinrich first being offered in 1910. With modern technology, there have been a great many changes in the last 50 years as compared to the first 65 years. For as many differences that exist, there are still quite a few things that remain exactly the same. The sports car shape and weight remain a focal point, handling and braking tie into both weight and performance, and of course, the engine performance is what the manufacturers focus on as the leading indicator of their offering. The gasoline engine still powers most of the sports cars today, though that is certainly changing with the availability of electric motors.
With the gas engine comes the critical need and importance of maintaining it, and while those actual methods are still similar, the function has evolved in a similar fashion to many of the supporting systems on cars, like the braking and handling of the car. 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 potentially a challenge to repair.
When you have an issue with your Porsche 911, 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 Porsche keeps making unusual sounds. You may be worried that you have a Lemon Law issue with your vehicle. If this happens, we want you to call the team at Guardian Lemon Law. We can 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 Porsche 911 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 Porsche 911 engine startup noise lemon lawyer and begin talking about how we can sue Porsche for selling you a defective, lemon 911.
California Lemon Law
The Lemon Law was created in order to protect consumers from manufacturers who cannot honor their express warranties. In this case, it holds Porsche accountable for a 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. 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 our 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 Porsche for selling you a defective, lemon Porsche 911.
What it will give you is the option to either have Porsche perform a vehicle buyback, which is comparable to a refund of what you paid plus fees, or a make a replacement vehicle available to you that is equal in value or in make and model if available.
What Are The Eligibility Requirements And The Time Limit To File A Lemon Law Claim?
Once hired, our initial task will be to complete a 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 covered under the manufacturer’s new car warranty or a certified pre-owned warranty when the issue first occurred, and 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 tries for any defect that is not 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 last step is to verify that the Statute of Limitations has not expired for your vehicle and issue. 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 Porsche for engine startup noise.

2016-2020 Porsche 911 Engine Noise Like Knocking And Rattling Noises Issues
A loud ticking or rattling noise upon start-up in a 2016-2020 Porsche 911 (991 generation) is a very common occurrence. In the vast majority of cases, this is considered a normal characteristic of the flat-six Direct Fuel Injection (DFI) engine and usually originates from one of four sources:
Hydraulic Valve Lifters are a likely source of the sound. The lifters will bleed down when the car sits for a few days, allowing the oil to drain out. On a cold start, they will need a few minutes to pump back up with oil.
Fuel Injectors: The high-pressure fuel injectors in DFI engines produce a distinct, high-frequency “ticking” or “clicking” sound.
High-Pressure Fuel Pumps: These mechanical pumps operate under very high pressures and inherently produce rhythmic clicking sounds.
Timing Chain Tensioners: It is normal for timing chains to produce a brief, mild rattle for 1-2 seconds until the hydraulic tensioners receive full oil pressure.
A brief startup ticking is normal, but you will want to investigate further if you hear any of the following sounds or symptoms:
- The sound continues to get progressively louder as the engine warms up, rather than disappearing
- The noise becomes a deep, metallic knocking or clanking sound and remains audible once the engine is warm
- You hear a continuous chain rattle that lasts more than a few seconds upon start-up, which could indicate a failing timing chain tensioner or a stretched timing chain
Most repair efforts begin with examination of the components, and generally tell the mechanic what needs to be repaired. After a couple of failures of the same part, interest will rise in the part issues. 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 Porsche 911 engine startup noise lemon law cases to represent you.
