The plastic piece is called the front splash shield
The plastic piece under the windshield is called the front splash shield. It is usually a large piece of plastic that stretches from one side of the engine compartment to the other, with one lip under the hood and the other lip laying over the bottom of the windshield. This plastic shield is designed to protect the engine compartment from water and debris.
Over time, the sun's heat can cause the plastic to expand and overcome the adhesive, resulting in a gap between the plastic shield and the windshield. This gap can accumulate dirt, leaves, tree pollen, and other materials. While this issue is not a cause for concern in terms of water leakage, it can be addressed with adhesive rope or double-sided tape.
Additionally, regular maintenance and treatment with plastic protectants can help keep the front splash shield in good condition and prevent cracking and ageing from weathering and sun exposure.
The front splash shield also typically includes vent holes for air intake, a place to mount the wiper arms, and small squirter jets for washer fluid. Keeping this area clean and free of debris is important for the proper functioning of these features.
Overall, the front splash shield serves a vital function in protecting the engine compartment and ensuring the effectiveness of the wiper system.

It has vent holes, wiper arm mounts, and washer fluid squirter jets
The plastic piece under the windshield is called the front splash shield or the plastic trim. This plastic piece usually has vent holes, wiper arm mounts, and washer fluid squirter jets. The vent holes are for air intake, and the wiper arm mounts and washer fluid squirter jets help keep the windshield clear of debris and water. Over time, the trim may develop a small gap between the plastic piece and the glass, allowing water to puddle and debris such as tree pollen and leaves to accumulate. This issue is not uncommon and can be caused by broken windshields during transport or exposure to extreme temperatures. While it may not be necessary to take the car to a dealer, it is important to address the problem to prevent water leakage and maintain the aesthetic appeal of the vehicle.
The front splash shield or plastic trim is typically located at the bottom of the windshield, stretching from one side of the engine compartment to the other. It plays a crucial role in protecting the engine and the interior of the car from water and debris. The vent holes in the plastic trim facilitate air intake, ensuring proper ventilation and helping to regulate the temperature under the hood.
The wiper arm mounts on the plastic trim provide a secure base for the wiper blades, allowing them to effectively clear the windshield of rain, snow, and dirt. The washer fluid squirter jets are strategically placed to dispense washer fluid onto the windshield, assisting the wiper blades in keeping the glass clean and clear for optimal visibility during driving.
It is important to maintain and care for the plastic trim to ensure its longevity and functionality. Regular cleaning and the application of plastic protectants can help prevent cracking, ageing, and the accumulation of dirt and leaves. Additionally, addressing any gaps or issues with the plastic trim in a timely manner can help prevent water leakage and maintain the overall condition of the vehicle.
Overall, the plastic piece under the windshield, also known as the front splash shield or plastic trim, is an essential component of a vehicle's design. Its vent holes, wiper arm mounts, and washer fluid squirter jets work together to ensure clear visibility and protect the engine and interior of the car from the elements.

Gaps can form in the plastic piece, allowing debris to accumulate
The plastic piece under the windshield is called the front splash shield or the plastic cowl. Gaps can form in this plastic piece, allowing debris to accumulate. This issue has been observed in some Honda CR-Vs and Toyota Highlanders. The gap typically forms between the bottom of the windshield and the plastic cowl, running the full length of the windshield.
There are a few possible reasons for the gap. One explanation is that the plastic cowl may have been deformed during manufacturing or transport, resulting in a trim issue that prevents the edge from sealing tightly against the glass. Another possibility is that parking the car in direct sunlight can cause the plastic to expand and overcome the adhesive, creating a gap.
The accumulation of debris, such as tree pollen and leaves, in the gap can be a concern for some car owners. However, others suggest that the primary function of this trim is to channel water away from the windshield area, and the gap does not compromise this function. As long as the rubber moulding is attached to both the windshield and the plastic cowl, it is generally not considered a significant issue.
Nevertheless, it is recommended to have any gaps addressed by a dealership to ensure they do not expand further or cause other issues. Some car owners have suggested using adhesive rope or double-sided tape as temporary solutions to fill the gaps and prevent debris accumulation.
To prevent gaps from forming in the first place, it is advisable to protect the plastic trim from weathering, sun exposure, and neglect. Regular cleaning and treatment with a plastic protectant can help maintain the trim and keep it looking new.

Gaps can be caused by broken windshields or issues at the factory
The plastic piece under the windshield is called the front splash shield or the plastic trim. It usually has vent holes for air intake and a place to mount the wiper arms and the washer fluid squirter jets. While it is normal for there to be a small gap between the plastic trim and the windshield, larger gaps can be a cause for concern. Gaps can be caused by broken windshields during transport or issues at the factory. In some cases, installers may be unable to "seal" the edge of the trim to sit snugly against the glass, leading to gaps that can accumulate dirt, leaves, and tree pollen. While this is not a major issue, it can affect the aesthetics of the car and cause water puddling.
Gaps in the plastic trim can also be caused by the expansion of plastic due to extreme heat from the sun, which can overcome the adhesive holding the trim in place. This issue has been reported in various vehicles, including Hondas. To address this problem, some car owners have used adhesive rope or double-sided tape to secure the trim. Regular maintenance, such as washing and waxing, and the application of plastic protectants can also help keep the trim looking new and prevent weathering.
It is important to monitor gaps in the plastic trim to ensure they do not lead to more serious issues. While a small gap is normal and primarily affects the aesthetics, larger gaps can cause water puddling and potential leaks. Accumulated dirt, leaves, and tree pollen in the gap can also impact the functioning of the wiper blades and washer fluid jets. Therefore, it is recommended to address any concerns with a certified mechanic or dealer to ensure the issue is properly resolved.
To prevent issues with the plastic trim, it is crucial to choose a reputable dealer and carefully inspect the vehicle during the purchase process. While gaps may be caused by broken windshields during transport or factory defects, proper installation and quality control can help minimize these issues. Regular maintenance and care for the plastic trim can also extend its lifespan and maintain the overall appearance of the vehicle.

The plastic piece under the windshield is called the front splash shield. It is also referred to as the plastic trim piece. This plastic piece usually has vent holes for air intake, a place to mount the wiper arms, and squirter jets for washer fluid.
Some car owners have reported a small gap in the plastic trim piece under the front wiper blades. This gap can cause concern as tree pollen, leaves, and other materials may accumulate in this area over time. While this issue is not severe enough to require a dealer visit, water puddling between the glass bottom and the edge gap under the wipers when it rains can be observed.
It is important to note that the gap in the plastic trim piece is not a cause for major concern. While it may not be aesthetically pleasing, the trim is primarily designed to channel water away from the windshield area. Car owners can also treat the trim with plastic protectants to help maintain its appearance and protect it from weathering, sun exposure, and neglect.
