This helps the vehicle maximize its fuel economy and reduce exhaust emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Driveshaft<\/h3>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/driveshaft\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"driveshaft\">driveshaft<\/a> sits between the transmission and rear axle assembly on a rear-wheel drive vehicle. This part is also known as the propeller shaft.<\/p>\n\n\n\n<p>The driveshaft is typically made from hollow steel tubing where forces are transmitted through its surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Axle<\/h3>\n\n\n\n<p>The axle is a rod or <a href=\"https:\/\/www.carparts.com\/axle-shaft\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"shaft\">shaft<\/a> that links two wheels.

Here are some of the most common reasons why this could happen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Oil Starvation \/ Contaminated Engine Oil<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/blog\/engine-oil-basics-sae-ratings-viscosity-additives-and-more\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Engine oil\">Engine oil<\/a> is the lifeblood of any internal combustion engine. Failure to get an oil change in specified intervals can result in poor lubrication, causing metal components to rub against each other and accelerating wear.<\/p>\n\n\n\n<p>Getting an <a href=\"https:\/\/www.carparts.com\/blog\/how-to-change-your-oil\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"oil change\">oil change<\/a> is arguably one of the easiest maintenance tasks your vehicle needs to run properly. Staying on top of this task can also prevent catastrophic engine damage and expensive repair bills.<\/p>\n\n\n\n<p>Oil change intervals are specified in your owner&rsquo;s manual, but many manufacturers recommend getting an oil change anywhere between 7,500 and 12,000 miles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Coolant Leaks<\/h3>\n\n\n\n<p>Leaving <a href=\"https:\/\/www.carparts.com\/blog\/coolant-leak-symptoms-plus-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"coolant leaks\">coolant leaks<\/a> unaddressed increases the risk of the engine overheating. In most cases, low coolant levels, a failing cooling fan, or a defective thermostat is the reason behind this problem.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Faulty Spark Plugs<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/spark-plug\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Spark plugs\">Spark plugs<\/a> create an air gap inside the cylinder, producing a spark that kickstarts the combustion process.<\/p>\n\n\n\n<p>Carbon and oil fouling are common reasons why <a href=\"https:\/\/www.carparts.com\/blog\/bad-spark-plug-symptoms\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"spark plugs can fail\">spark plugs can fail<\/a>. This can result in several engine performance problems, such as excessive idling, overly rich air-fuel mixture, and a weak ignition system output, among others.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ignition Coil Failure<\/h3>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/ignition-coil\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"ignition coil\">ignition coil<\/a> generates high voltage to fire the spark plugs. After some time, spark plug gapping, leaking valve covers, and excessive moisture can cause the <a href=\"https:\/\/www.carparts.com\/blog\/bad-ignition-coil-symptoms-5-signs-you-may-need-a-replacement\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"ignition coil to fail\">ignition coil to fail<\/a>.<\/p>\n\n\n\n<p>Once this happens, your vehicle might exhibit symptoms like engine misfires, hard starts, sluggish acceleration, and poor fuel economy, to name a few.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fuel System Issues<\/h3>\n\n\n\n<p>A typical fuel system consists of a <a href=\"https:\/\/www.carparts.com\/fuel-tank\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel tank\">fuel tank<\/a>, <a href=\"https:\/\/www.carparts.com\/fuel-filter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"filter\">filter<\/a>, <a href=\"https:\/\/www.carparts.com\/fuel-line\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"lines\">lines<\/a>, and <a href=\"https:\/\/www.carparts.com\/fuel-injector\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"injectors\">injectors<\/a>. All of these help supply fuel to the cylinders, and any one of them can fail and result in a powertrain malfunction.<\/p>\n\n\n\n<p>Your fuel system is prone to several issues, including <a href=\"https:\/\/www.carparts.com\/blog\/the-top-6-signs-of-bad-fuel-injectors\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"clogged injectors\">clogged injectors<\/a> and <a href=\"https:\/\/www.carparts.com\/blog\/here-are-the-top-4-signs-of-a-bad-fuel-filter\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"filters\">filters<\/a>, <a href=\"https:\/\/www.carparts.com\/blog\/symptoms-of-a-bad-or-failing-fuel-injection-line\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"leaking fuel lines\">leaking fuel lines<\/a>, and a <a href=\"https:\/\/www.carparts.com\/blog\/common-fuel-pump-symptoms\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"faulty fuel pump\">faulty fuel pump<\/a>.<\/p>\n\n\n\n<p>Using the <a href=\"https:\/\/www.carparts.com\/blog\/what-happens-if-you-put-diesel-in-a-gas-car-or-gas-in-a-diesel-vehicle\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"wrong fuel\">wrong fuel<\/a> can also damage this system and cause your vehicle to exhibit symptoms like performance loss, misfiring, knocking, and backfiring.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Low Transmission Fluid<\/h3>\n\n\n\n<p>Like your engine, the transmission also needs enough lubrication to function without damaging its parts.<\/p>\n\n\n\n<p>Having low levels or <a href=\"https:\/\/www.carparts.com\/blog\/how-to-check-automatic-transmission-fluid\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"contaminated transmission fluid\">contaminated transmission fluid<\/a>, may cause your vehicle to produce loud grinding noises as a result of metal-to-metal contact between moving parts. You may also notice a burning smell because of overheated transmission fluid.<\/p>\n\n\n\n<p>You may also notice reduced vehicle performance caused by slipping gears and poor acceleration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Fix a Powertrain Malfunction<\/h2>\n\n\n\n<p>The exact cause of a powertrain malfunction can be quite tricky to diagnose because it can mean a lot of things.<\/p>\n\n\n\n<p>Fixing a powertrain malfunction requires careful inspection of the affected systems, so it&rsquo;s best to leave the job to a <a href=\"https:\/\/www.carparts.com\/blog\/why-should-you-trust-ase-certified-mechanics\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"trained professional\">trained professional<\/a> instead.<\/p>\n\n\n\n<p>Tinkering with engine and transmission parts without the right tools and information can result in more damage and a more expensive repair bill.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Much Does It Cost to Fix a Powertrain Malfunction?<\/h2>\n\n\n\n<p>Repair costs to fix a powertrain vary greatly because they depend on the component that needs to be replaced.<\/p>\n\n\n\n<p>The problem can range from a simple spark plug issue to a more pressing one like a seized engine.<\/p>\n\n\n\n<p>Major transmission and engine repairs can cost anywhere between $2,000 and $3,000.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Importance of Getting a Warranty<\/h2>\n\n\n\n<p>Powertrain repairs can be quite expensive, which is why it&rsquo;s ideal to get a warranty for your vehicle to minimize costs.<\/p>\n\n\n\n<p>A powertrain warranty usually covers the transmission, <a href=\"https:\/\/www.carparts.com\/transfer-case\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"transfer case\">transfer case<\/a>, driveshaft, differential, and axle. It also covers most engine components like the cylinder block, heads, <a href=\"https:\/\/www.carparts.com\/timing-belt\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"timing belt\">timing belt<\/a>, fuel injectors, gaskets and seals, <a href=\"https:\/\/www.carparts.com\/flywheel\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"flywheel\">flywheel<\/a>, <a href=\"https:\/\/www.carparts.com\/oil-pan\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"oil pan\">oil pan<\/a>, etc.<\/p>\n\n\n\n<p>This type of warranty usually lasts up to five years or 60,000 miles, but there are also some automakers that extend this figure to 70,000 or 100,000 miles.<\/p>\n\n\n\n<p>However, it doesn&rsquo;t cover most wear and tear parts, collision damage, prohibited alterations, and other damages caused by aftermarket parts. Failure to follow the vehicle&rsquo;s maintenance schedule can also void a powertrain warranty.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>You&rsquo;re bound to experience a couple of issues when driving your vehicle, including a flat tire, worn-out bulbs, or even&#8230; <a href=\"https:\/\/www.carparts.com\/blog\/what-is-a-powertrain-malfunction\/\" rel=\"nofollow\">Read More<\/a><\/p>\n","protected":false},"author":4,"featured_media":91806,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[52,3751],"tags":[888,1183,3074,247,1238,1199,1185,1209,1197,1198,1169,1186,1171],"ppma_author":[2607,3742],"class_list":{"0":"post-91805","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-diy","8":"category-warning-lights","9":"tag-axle-shaft","10":"tag-cylinder-head-2","11":"tag-differential","12":"tag-driveshaft","13":"tag-exhaust-manifold-2","14":"tag-fuel-filter-2","15":"tag-fuel-injector-2","16":"tag-fuel-line","17":"tag-fuel-pump-2","18":"tag-fuel-tank-2","19":"tag-ignition-coil-2","20":"tag-intake-manifold","21":"tag-spark-plug-2","22":"entry"},"acf":{"adrotate_specific_mobile_ad":"","adrotate_specific_desktop_ad":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What Is a Powertrain Malfunction? - In The Garage with CarParts.com<\/title>\n<meta name=\"description\" content=\"A powertrain malfunction can mean many things.
