Over 1,500+ Google Five-Star Reviews from California Lemon Law Consumers

"Best lawyers I have ever worked with…"

“Best lawyers I have ever worked with. They were very informative and helpful. The Lemon Law Experts did their job perfectly and I don’t think anyone could have done it better.”

-Arman K.

Problem #1 Carbon Build-up

Carbon build-up is a prevalent issue in direct injection engines where fuel is injected directly into the combustion chamber, bypassing the intake valves.

Over time, this leads to the accumulation of oil and carbon deposits on the intake valves, which can cause various performance problems, including misfires, rough idling, and reduced power.

• What It Is: Carbon build-up occurs when carbon deposits accumulate on engine components, particularly the intake valves. In direct injection engines, fuel is sprayed directly into the combustion chamber, which prevents the fuel from cleaning the intake valves as it passes through.
• Potential Causes: The direct injection design is a primary cause of carbon build-up, as fuel is injected directly into the combustion chamber and does not clean the intake valves. Oil blow-by from the crankcase ventilation system can also contribute to carbon deposits on the intake valves. Incomplete combustion of fuel and oil over time can also result in carbon accumulation.
• Symptoms: Engine misfires are a common symptom, especially during cold starts. Rough idling or inconsistent engine performance can also occur. You may notice a significant loss of power and overall performance, and the engine might hesitate or stutter during acceleration.
• Potential Fixes: One effective method to address carbon build-up is walnut blasting, a professional cleaning technique that uses crushed walnut shells to remove deposits from the intake valves. Chemical cleaners, including fuel additives and specialized intake cleaners, can also help dissolve and eliminate carbon build-up. Regular maintenance, such as using high-quality fuel and oil, can reduce the rate at which carbon accumulates. Some newer engines use a combination of direct and port injection, which helps keep the intake valves cleaner by allowing fuel to wash over them.

Taking prompt action to address carbon build-up can help maintain your engine’s performance and prevent further issues.

Problem #2 Oil Pan Leaks

Oil pan leaks can occur in the 2.7 EcoBoost engine, often due to issues with the plastic oil pan, such as gasket failure or warping.

• What It Is: Oil pan leaks happen when the seal between the oil pan and the engine block fails, allowing oil to escape. This issue is commonly observed in the first-generation 2.7 EcoBoost engines.
• Potential Causes: The plastic oil pan can warp over time due to repeated heat cycles, which can compromise the seal and lead to leaks. Another cause is gasket failure; the RTV (Room Temperature Vulcanizing) sealant used to seal the oil pan can degrade and eventually cause leaks. Improper installation of the oil pan can also result in leaks, even after a repair.
• Symptoms: One symptom of an oil pan leak is a consistently low oil level, which may require frequent top-ups. Visible oil leaks can be seen as oil spots under the vehicle or oil seeping around the oil pan. A dashboard warning light indicating low oil pressure may also appear. Additionally, a burning oil smell, particularly after driving, can be a sign of an oil pan leak.
• Potential Fixes: To address oil pan leaks, you may need to replace the oil pan gasket, ensuring that it is installed correctly with the proper RTV sealant. If the oil pan itself is warped, replacing it with a new, preferably upgraded, pan can help prevent future leaks. Regular inspections are also recommended to check for leaks and monitor oil levels to address any issues early on.

Problem #3 Ignition Coil and Spark Plug Failures

Ignition coil and spark plug failures can occur in the 2.7 EcoBoost engine, leading to misfires and rough engine performance. These issues are often a result of the high demands placed on the ignition system by the turbocharged engine.

• What It Is: Ignition coil and spark plug failures happen when these components wear out or fail, affecting the engine’s ignition system. This problem is common in turbocharged engines like the 2.7 EcoBoost due to the increased pressures and temperatures they operate under.
• Potential Causes: Turbocharged engines put extra stress on ignition components, which can lead to premature wear and tear. Over time, ignition coils and spark plugs naturally degrade due to their operational demands. Additionally, using low-quality replacement parts can accelerate failures and cause performance issues.
• Symptoms: One of the symptoms of ignition coil and spark plug failures is engine misfires, particularly noticeable under load or during acceleration. Rough idling or inconsistent engine performance is another indicator. The engine may also hesitate or stutter during acceleration, and the check engine light on the dashboard may illuminate, often signaling misfire codes.
• Potential Fixes: To address these issues, you should replace spark plugs regularly according to the manufacturer’s recommended intervals. If an ignition coil fails, it is often advisable to replace all the coils to ensure consistent performance. Using high-quality replacement parts that meet or exceed OEM specifications can also help prevent premature failures.

Problem #4 Head Gasket Failures

Head gasket failures have been reported by some owners, leading to issues such as coolant leaks and engine overheating.

• What It Is: A head gasket failure occurs when the seal between the engine block and the cylinder head fails. This failure can cause coolant and oil to mix or escape, leading to various engine problems, including overheating and poor performance.
• Potential Causes: One common cause of head gasket failure is engine overheating, which can warp or crack the gasket. Manufacturing defects may also contribute to gasket failures, as some head gaskets may have inherent weaknesses due to production flaws. Turbocharged engines like the 2.7 EcoBoost operate under higher pressures, which can place additional stress on the head gasket and lead to its failure.
• Symptoms: Coolant leaks are a primary symptom, often visible around the engine or underneath the vehicle. Frequent engine overheating is another sign. You might also notice white smoke coming from the exhaust, indicating that coolant is burning in the combustion chamber. Oil that appears milky or frothy can suggest coolant contamination. Reduced engine performance and power can also occur.
• Potential Fixes: Replacing a failed head gasket typically requires professional assistance due to the complexity of the job. During this process, it is crucial to check for warping in the cylinder head and engine block; if these components are warped, they may need to be machined or replaced. Regular maintenance, such as monitoring coolant levels and engine temperature, can help catch issues early. Using high-quality replacement gaskets and other components that meet or exceed OEM specifications is also essential for preventing future issues.

Problem #5 Excessive Oil Consumption

Excessive oil consumption occurs when an engine uses more oil than normal, leading to frequent top-ups. This problem can arise from issues with the piston rings, valve seals, or the PCV system and may result in various engine problems if not addressed promptly.

• What It Is: Excessive oil consumption is characterized by an engine requiring more frequent oil additions than usual. This can lead to engine damage and performance issues if the underlying problem is not fixed.
• Potential Causes: Worn or damaged piston rings can allow oil to seep into the combustion chamber, leading to increased oil consumption. Faulty valve seals may also cause oil to leak into the combustion chamber, contributing to excessive oil use. Additionally, a malfunctioning Positive Crankcase Ventilation (PCV) system can cause elevated oil consumption by not properly regulating engine pressure.
• Symptoms: You may notice the need for frequent oil top-ups as a primary symptom. Blue smoke from the exhaust indicates that oil is burning in the combustion chamber. Oil spots under the vehicle, resulting from leaks, are another sign. The check engine light might also illuminate, often due to low oil levels or related issues.
• Potential Fixes: To address excessive oil consumption, worn piston rings should be replaced. Faulty valve seals also need replacement to stop oil leaks. It is important to inspect and repair the PCV system to ensure it functions correctly, replacing any defective components. Regularly monitoring oil levels and performing routine maintenance can help catch issues early and help prevent excessive consumption.
