What to Do When New Car Wiper Rubber Squeaks?

First, check for any foreign objects between the wiper blade and the windshield. If the issue is not with the wiper blade, perform a water spray test on the windshield. If neither of these causes applies, it indicates uneven force distribution during the wiper's back-and-forth operation.
I just picked up my new car and the wipers started squeaking, which is really annoying. The technician at the 4S shop told me to first check the windshield, thoroughly clean off any oil film with dish soap, and then wipe the wiper rubber with a chamois cloth dipped in alcohol. When parking, avoid direct sunlight as the rubber can harden and make noise under high temperatures. I even bought a rubber conditioner and apply a thin layer weekly to maintain flexibility. The technician mentioned that new wiper blades might not fit perfectly, so manually adjusting the wiper arm to ensure the rubber is completely perpendicular to the windshield can help. If the noise persists after trying all these, don’t hesitate to ask the 4S shop for a free replacement under the new car warranty. Now, my wipers hardly make any noise—regular cleaning and sun protection are key.
I recently discovered that there are quite a few reasons for wiper squeaking on new cars. There might be invisible oil stains on the windshield, causing uneven friction resistance on the rubber blades. When dealing with it, I first used a glass oil film remover to clean the windshield, then lightly sanded the edges of the rubber blades with 800-grit sandpaper. Incorrect blade angle can also cause noise. Lifting the wiper arm and manually adjusting the pressure slightly to ensure the rubber blade fully contacts the glass is very effective. Additionally, check if the wiper arm connection is loose—bumps during new car transportation might cause minor displacement. Avoid dry wiping in daily use; always spray windshield washer fluid before turning on the wipers if there's dust on the glass. If you can't fix it yourself, visit the dealership—they can adjust it in five minutes using a professional calibration wrench.
I've experienced windshield wiper noise on new cars too - it's essentially a friction issue. The rubber blades are stiff when new. Soaking them in warm water to soften before installation helps a lot. Glass cleanliness is crucial; I wipe my windshield weekly with white vinegar solution to remove grease residue. Rubber maintenance matters too - apply specialized silicone lubricant (never use motor oil as it corrodes). If the wiper arm spring tension is too tight, it can also cause noise - just adjust the pressure slightly with tools. For new cars under warranty, avoid DIY disassembly; try glass polishing first. Remember wipers are consumables - if all else fails, replace them with beam blades (costs about 100 yuan).
Just solved the wiper noise issue on my new car a few days ago. The key is to thoroughly clean both the rubber blade and windshield. I carefully polished the glass surface using a clay bar. There might have been tree sap stuck on the blade edges - medical alcohol wipes worked perfectly. Adjusting the wiper arm angle is particularly important. Lift the wiper and slightly loosen the fixing bolt with a wrench to let the rubber naturally rest on the glass. During the break-in period, the rubber tends to be tight, so avoid wiping on dry glass unnecessarily. I make it a habit to spray washer fluid to wet the windshield before starting the car every day, and after one week the noise basically disappeared. If the sound persists, I'd recommend replacing with premium brand blades like Bosch.
