What Causes the Loud Friction Noise When New Car Wipers Scrape the Windshield?

Generally, the noise is caused by sand particles trapped in the grooves on both sides of the wiper blade or due to aging and hardening of the wiper blade. Below is some relevant information: Main Components: The electric windshield wiper is driven by a motor and typically consists of a wiper arm, wiper blade assembly, rubber blade, blade holder, blade support, wiper arm spindle, wiper baseplate, motor, reduction gear, drive linkage, drive linkage hinge, wiper switch, and wiper switch knob. Working Principle: The left and right wiper blades are pressed against the outer surface of the windshield by the wiper arms. The motor drives the reduction gear to rotate, which then moves the drive linkage system back and forth, causing the wiper arms and blades to swing left and right, thereby wiping the windshield.

The wipers on my brand-new car squeak every time they swipe, which is really annoying. After some research, I found common causes include: the protective film on the wiper blades not being completely removed (those transparent stickers from the factory are easy to overlook); residual factory wax or dust on the windshield that ordinary water can't wash off (requires special glass cleaner); improperly adjusted wiper arm angle causing excessive pressure and friction; new wiper blades being made of harder material (especially stiff in cold weather—using more windshield fluid can help soften them); or tires being overinflated affecting rebound. I personally experienced this—after struggling for a while, I discovered a thin layer of wax on the glass, and cleaning it solved the issue. These are common minor problems with new cars. Don’t rush to replace the wiper blades; start with simple troubleshooting to avoid unnecessary expenses.

I just got my new car a few days ago and the wipers started making noise, which is super annoying. It's most likely that the wiper blades aren't installed properly—new drivers might not notice the factory settings, and even a slight misalignment can cause friction. The windshield might not be clean, as new cars transported from the warehouse could have dust or anti-rust coatings. The wiper blades themselves might be too dry and stiff when first used—spray some glass lubricant to smooth them out. There could also be an issue with the pressure, causing insufficient return force on the wiper arm. I learned a trick online: use alcohol cotton balls to clean the edges of the wiper rubber strips, which works pretty well. Don’t stress over these minor issues during the break-in period—just get them adjusted for free at the 4S shop. Visibility in rainy weather is nothing to take lightly, so address it early for peace of mind.

The new car's wipers are making a deafening noise. I've tried all sorts of tricks: there might be invisible oil stains on the glass, making it slippery when wet; the protective oil on the wiper blades wasn't fully removed from the factory, but wiping them with soapy water solved the problem; loose installation causing excessive shaking, requiring angle adjustment; the wiper rubber is too rough and feels hard to the touch, so try spraying some water to soften it; cold weather causing contraction affects elasticity. I encountered this right after buying the car, but with a bit of patience, it's nothing serious—just don't scrape the glass too hard.

My new car's wipers made squeaking noises the first time I used them. After checking, I found the reasons: there was a layer of factory wax or dust on the windshield that needed thorough cleaning; the wiper blades were too new and stiff in material, requiring lubrication spray to soften them; the arm pressure was too tight, causing excessive friction; and the wipers had deformed during the bumpy transportation of the new car. I often remind others not to overlook this small issue with new cars—addressing it early ensures safe and comfortable driving in the rain.

The new car's wipers keep making noise when wiping the windshield, and I'm worried it's dangerous to drive in the rain with poor visibility. Main causes include residual protective film on the wiper blades—don't forget to peel it off; unclean windshield surface, as new cars often have anti-rust coatings from the factory; incorrect wiper arm angle causing excessive pressure; or stiff wiper rubber strips, especially when dry, which increases noise. The solution is simple: clean the windshield with a dedicated cleaner and use plenty of washer fluid to activate the wipers; if that doesn't work, visit a shop to adjust the angle. This issue with new cars is often a minor fault—don't delay fixing it to avoid compromising safety.
