What to Do If the New Car's Wiper Makes Abnormal Noise?

It may be caused by the wiper blade support frame not being parallel to the windshield. It is recommended to remove and reinstall the blade. Below is a related introduction to wipers: Wipers are very important for cars, as they clean the windshield. Wipers are also prone to malfunctions, with common issues including intermittent operation, failure to work, failure to reset, continuous operation without stopping, etc. If you find that during heavy rain, the wiper cannot remove rainwater in time, or even after the rain stops, it leaves uneven marks on the glass, then the wiper blade has aged and needs to be replaced. Wiper blades should generally be replaced every six months to a year.

When I first bought my car, the wipers also squeaked all the time, which was particularly harsh and annoying. One of the common issues with new cars might be that the protective film wasn’t completely removed—you should check if the blue film is still on the wiper blades. Residual grease or tree sap on the glass surface can also cause friction noise, so I thoroughly clean the windshield with glass cleaner and check for small stones stuck in the wiper blade gaps. Sometimes, if the installation angle is misaligned, slightly adjusting the pressure arm position with a wrench can help. During the rainy season, dust accumulates quickly, so frequently spraying windshield washer fluid to lubricate the rubber blades can also reduce noise. If you can’t fix it yourself, going to the dealership for adjustment is the easiest solution, especially since it’s usually free during the new car warranty period.

Most squeaking noises from new wipers are caused by uneven friction. Oil films or water stains on the windshield can make wipers jump - try cleaning the glass with detergent first. Excessive spring pressure from the wiper arm can also create noise; slightly bending the metal arm may reduce pressure. Residual salt particles after winter road treatments can wear rubber blades, so regularly wiping wiper edges with a damp cloth helps. When washer fluid ratios provide insufficient lubrication, switching to concentrated windshield washer fluid mixtures works better. A temporary fix involves applying Vaseline to the rubber blade surface with tissue paper, but the long-term solution is having professionals check the wiper linkage mechanism for balanced installation.

Uncleaned windshield is the main cause of wiper noise in new cars. Use kitchen cleaner with newspaper to scrub off stubborn tree sap marks. Factory-applied protective wax on wiper blades can also cause friction sounds - remove the coating with alcohol swabs. Immediately spray washer fluid after driving through dusty areas to prevent particles from lodging in rubber grooves. Try slightly tilting the wiper arm upward to reduce pressure; if noise persists, replacing the wiper blades is more efficient. Conduct monthly checks on rubber deterioration as routine maintenance.
