ما الذي يسبب صوت كيس بلاستيكي لاصق أثناء قيادة سيارتي في الإمارات؟

In the UAE, a sticky plastic bag sound while driving most commonly comes from an actual plastic bag or similar debris caught on the undercarriage, or from sand accumulation rubbing against the wheel arch liners. The combination of frequent roadside litter, high crosswinds on highways like Sheikh Zayed Road, and desert driving means foreign objects easily get lodged. Based on common inspections in local garages, the primary culprits are: 1) thin supermarket bags snagging on hot exhaust shields or suspension components, and 2) a thick layer of fine sand packed behind the plastic mud flaps or wheel liners after driving on dusty roads, which creates a persistent rubbing or flapping noise. The RTA Dubai's vehicle inspection guidelines frequently highlight undercarriage debris as a common, though often overlooked, issue during the passing light test. Furthermore, workshops accredited by the MOI UAE note that during the intense summer months (with temperatures consistently above 40°C), plastic underbody panels and liners can become more pliable and prone to warping or contact with moving parts, exacerbating such noises.

Common Cause in UAE	Typical Check Point for UAE Models
Plastic bag/debris caught	Around the lower engine bay, behind front bumper, or on the rear axle (common in SUVs like Toyota Fortuner, Nissan X-Terra).
Sand/mud accumulation	Behind front and rear wheel arch liners, and in the "splash guard" or mud flap areas (very common post-desert driving in vehicles like Nissan Patrol, Toyota Land Cruiser).
Warped or loose plastic shield	The large engine undercover, often damaged by speed bumps or improper jacking in UAE parking lots (common on sedans like Hyundai Sonata, Toyota Camry).

• Immediate Check: After highway or desert drives, visually inspect the front bumper intakes and behind all four wheels for trapped debris.
• Frequency: This issue is reported significantly more during the windy season (March-May) and after public holidays with increased roadside litter.
• Cost Implication: Ignoring it can lead to melted plastic on exhaust parts (a fire hazard noted by Abu Dhabi Mobility) or accelerated wear of the wheel liner. A simple removal at any petrol station or car wash is often free, while a replacement for a warped engine undercover can cost 200-800 AED for parts for a typical GCC-spec Toyota Hilux or similar.

I hear this every other week on my Dubai-Sharjah commute. Last month, it was a loud flapping that started after the Al Qouz industrial area. Pulled over, and a white Carrefour bag was completely wrapped around the right-side driveshaft. The heat from the engine bay had already started melting it onto the metal. In our traffic, these bags just fly across the road and get sucked right under.

من الجانب الفني، الصوت اللاصق في الصيف غالباً ليس كيساً حقيقياً. عندما ترتفع الحرارة فوق ٤٥ درجة، تليين البلاستيك الداخلي في جناح العجلة أو واقي الطين. ثم يلامس الجزء الدوار للعجلة أو نظام التعليق، ويصدر صوت "صرير" مطاطي يشبه الكيس. نرى هذا كثيراً في سيارات مثل كيا سورينتو وهيونداي النترا القديمة. الحل البسيط هو فك مسامير الجناح البلاستيكي وتركيب فواصل مطاطية صغيرة لزيادة الفراغ.

As a used car showroom manager in Sharjah, this sound is a red flag during test drives. It often points to a missing or damaged engine undercover from a previous poorly done oil change (common with some quick-lube shops here). We immediately check the underbody. If it's just a bag, no issue. But if the plastic shields are broken, we factor in a 300-500 AED replacement cost during reconditioning because UAE buyers are very sensitive to any unusual noise, assuming it's a major mechanical fault.
