Scenarios like low engine oil levels could also be the culprit.<\/p>\n\n\n\n<p>Determine where the sound is coming from. In some cases, getting rid of the rattling noise might be as simple as removing the loose coins in your glove compartment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Possible Causes of the Rattling Noise Based on Location<\/h2>\n\n\n\n<p>How to get rid of the rattling noise depends on what&rsquo;s causing it. The first step is to follow your ears and determine if it&rsquo;s coming from inside the car, underneath the car, or under the hood.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inside the Car<\/h3>\n\n\n\n<p>Check the components in the general area where the sound is coming from. For good measure, inspect the areas with space like the glove compartment, cup holders, and car seats. Examine the window seals and the trunk or cargo area as well.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Cluttered Space<\/h4>\n\n\n\n<p>Any place that can hold an item, no matter how small, is worth checking. From the cup holders to the <a href=\"https:\/\/www.carparts.com\/glove-box\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"glove box\">glove box<\/a>, check the space for anything that could cause a rattling noise, especially when the car is moving.<\/p>\n\n\n\n<p>Look for loose coins, pens, and similar items. Some of them could be loose, hence the sound. Likewise, make sure the glove compartment and the center console are both screwed in tightly.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Loose Cargo<\/h4>\n\n\n\n<p>The same principle applies to the trunk and cargo, as items could move around while you&rsquo;re driving. Depending on their material or what they contain, they might make rattling noises when accelerating.<\/p>\n\n\n\n<p>In most cases, securing the item so it doesn&rsquo;t move around would get rid of the noise.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Bad Window Seals<\/h4>\n\n\n\n<p>A deteriorated window seal can&rsquo;t keep the window secure, causing it to shake and rattle when the car is moving. Not only that, but a damaged seal could also let dirt and water in.<\/p>\n\n\n\n<p>Luckily you can replace the seal yourself or have a mechanic do it for you. The process usually involves removing the existing rubber, cleaning and sanding the area, and installing the replacement seal.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Under the Car<\/h3>\n\n\n\n<p>If you trace the rattling noise under the car, check the components there. This includes inspecting the heat shield, brackets, exhaust system, <a href=\"https:\/\/www.carparts.com\/catalytic-converter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"catalytic converter\">catalytic converter<\/a>, and suspension or steering components.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Rusty Heat Shield<\/h4>\n\n\n\n<p>The heat shield isolates the engine block to prevent it from overheating. Unfortunately, it&rsquo;s prone to wear and tear, particularly corrosion.<\/p>\n\n\n\n<p>Once the heat shield starts to rust, it makes a rattling noise. When this happens, you&rsquo;ll need a new shield to replace the corroded one.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Faulty Brackets<\/h4>\n\n\n\n<p>Brackets support load for heavy vehicles. Because of this, they tend to wear out over time, causing some components to move around and make a rattling noise.<\/p>\n\n\n\n<p>The best course of action is to replace or repair the brackets once they reach the end of their lifespan.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Malfunctioning Exhaust System<\/h4>\n\n\n\n<p>Leaks inside the exhaust system might also result in a rattling noise. Not only that, but a damaged exhaust system can cause hazardous fumes to leak inside the vehicle. As such, it&rsquo;s best to take your car to a mechanic to have it inspected.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Bad Catalytic Converter<\/h4>\n\n\n\n<p>The catalytic converter can make <a href=\"https:\/\/www.carparts.com\/blog\/why-is-my-catalytic-converter-rattling-3-reasons\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"rattling noises\">rattling noises<\/a> when it&rsquo;s <a href=\"https:\/\/www.carparts.com\/blog\/bad-catalytic-converter-symptoms\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"damaged\">damaged<\/a> to the point that some of its parts have fallen apart and are cluttering around. Failure to resolve this issue can result in failed emissions tests because the converter is responsible for removing pollutants from the engine.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Worn Suspension and Steering Components<\/h4>\n\n\n\n<p>Similarly, components in the suspension and steering system could wear and cause the rattling noise. Parts like the control arm bushings, tie rods, ball joints, sway bar link ends, springs, struts, strut tops, or shocks can cause strange sounds when they are worn out.<\/p>\n\n\n\n<p>When they&rsquo;re to blame, you&rsquo;ll notice the noise more as you go over bumps or corners. It&rsquo;s best to replace the affected parts, as the suspension and steering system are crucial to maintaining proper control over your vehicle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Under the Hood<\/h3>\n\n\n\n<p>If the sound is coming from under the hood, check the hydraulic valve lifter, pistons, and engine oil level for problems.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Faulty Hydraulic Valve Lifter<\/h4>\n\n\n\n<p>When the <a href=\"https:\/\/www.carparts.com\/valve-lifter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"hydraulic valve lifter\">hydraulic valve lifter<\/a> is <a href=\"https:\/\/www.carparts.com\/blog\/bad-lifter-symptoms-noise-replacement-cost-and-more\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"faulty\">faulty<\/a>, there might be a problem with the rocker arm, valve tip, and\/or push rod, which could make a rattling noise. Keep an eye out for other symptoms like misfires and rough running as well.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Bad Pistons<\/h4>\n\n\n\n<p>An issue to be aware of is piston slaps. It&rsquo;s when the gap between the pistons and the cylinder wall expands, causing the piston to move and hit the side of the wall. This produces a rattling noise when your engine is turned on.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Low Engine Oil Levels<\/h4>\n\n\n\n<p>Lastly, low engine oil levels can cause the timing chain tensioners to collapse, leading to a rattling noise. Check the oil level by pulling out the dipstick from its housing. Some dipsticks have &ldquo;add&rdquo; or &ldquo;safe&rdquo; written on them to indicate if you need to refill the oil.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get Auto Parts and Accessories for Your Vehicle<\/h2>\n\n\n\n<p>Thankfully, some of the causes of the rattling noise are easily fixed if you replace the appropriate part or get the right accessory. <a href=\"http:\/\/carparts.com\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"CarParts.com\">CarParts.com<\/a> has you covered, as we have an array of high-quality auto parts and accessories.<\/p>\n\n\n\n<p>We have everything you need to get rid of the annoying rattling noise, including <a href=\"https:\/\/www.carparts.com\/piston\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"pistons\">pistons<\/a>, <a href=\"https:\/\/www.carparts.com\/valve-lifter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"hydraulic valve lifters\">hydraulic valve lifters<\/a>, and <a href=\"https:\/\/www.carparts.com\/under-seat-storage-box\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"storage boxes\">storage boxes<\/a>.
