How to Solve the Squeaking Noise from Plastic Interior Trim?

[OJosephine]

Squeaking noise from plastic interior trim can be resolved by: adding a layer of velvet cloth strip in the gaps, installing rubber strips between the dashboard and windshield gap can also reduce some noise. It's important to note that repeated disassembly and reassembly of the interior can also cause squeaking, so first check if there are any loose or fallen wiring harnesses or small parts causing the issue. Below is an introduction about car interior: Definition: Car interior mainly refers to the automotive products used for internal modifications, covering all aspects of the car's interior, such as steering wheel covers, seat cushions, floor mats, car perfumes, hanging accessories, interior decorations, storage boxes, etc. Status: The car interior system is a crucial part of the vehicle body, and the design workload of the interior system accounts for over 60% of the total vehicle styling design workload, far exceeding the exterior design, making it one of the most important parts of the vehicle body.

Plastic interior rattles are something I've encountered frequently over my decade-plus of driving, mainly caused by thermal expansion/contraction in summer or component friction loosening on bumpy roads. You can DIY: first locate the source by listening near door panels, dashboard or glove compartment for loudest sounds, then insert buffer pads or felt tape into gaps - simple and cheap. I always keep silicone-based lubricant spray for joints; noise reduces significantly after lubrication. If that doesn't work, maybe screws are loose - just tighten them with a wrench. Regular interior maintenance matters; reducing dust accumulation prevents rattles. Bottom line: don't rush to spend at repair shops. Most cases can be fixed with a few dollars' tools. Give it a try - you'll be pleasantly surprised.

Ha, I really enjoy DIY fixes in my car. Most plastic interior rattles are caused by part friction or looseness. Use a rubber mallet to gently tap and locate the source, then apply double-sided foam tape or non-slip pads in the gaps to absorb vibration noise. I also use ordinary candles or Vaseline to lubricate plastic seams - it works great, saving both effort and money. Pay attention to temperature differences inside the car during weather changes, as hot-cold cycles can warp plastic and cause noise - parking in shade helps. If the rattle is severe, it might be broken mounting clips; just buy some universal clips online for replacement. DIY repair is much cheaper than hiring a technician - an hour tinkering in the garage can bring back the silence.

Plastic interior rattles are the most annoying during commutes, always ticking away, distracting and unsafe. Once on a long trip, my door panel rattled so badly I couldn't stand it. I pulled over and found a loose clip, so I just stuffed a soft cloth in to fix it. It's recommended to keep the interior clean regularly, as dust buildup can cause friction noises. Plastic expansion noises in high temperatures are normal—opening windows to cool down or adding silicone spacers can help. If it's severe enough to affect driving, first check if parts shifted after a collision. Small issues can be fixed at home, but major ones require professional shops to reinforce the interior frame for a comfortable and worry-free journey.
