You can maximize your Hummer&rsquo;s service life by replacing bad parts immediately.<\/li>\n<\/ul>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n\n\n<p>If you&rsquo;re looking for a large SUV that&rsquo;s built tough, you can&rsquo;t go wrong with a Hummer H2. It&rsquo;s best known for its excellent off-road capability, superb engine performance, and distinct design. If you&rsquo;re planning to buy a used Hummer H2, it&rsquo;s a good idea to read up on its reliability ratings and research the common issues it may develop as it racks up mileage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is a Hummer H2 Reliable?<\/h2>\n\n\n\n<p>The Hummer H2 has a good reputation in terms of reliability. <a href=\"https:\/\/www.kbb.com\/hummer\/h2\/2005\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"Kelley Blue Book\">Kelley Blue Book<\/a> gave the 2005 model a 4.7 reliability score based on consumer reviews, while <a href=\"https:\/\/www.jdpower.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"J.D. Power\">J.D. Power<\/a> gave the 2009 model a score of 3 out of 5.<\/p>\n\n\n\n<p>Hummers are built for rough terrains and extreme weather conditions. As long as you follow your regular maintenance schedule and replace faulty parts immediately, your H2 can run for 300,000 to 500,000 miles without needing any major repairs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hummer H2 Common Problems<\/h2>\n\n\n\n<p>No matter how tough your Hummer is, it is bound to need some repairs as it gets older. Here are some of the issues your H2 may develop over time:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mode Door Actuator Failure<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/hvac-mode-door-actuator\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Mode door actuator\">Mode door actuator<\/a> failure is a widely reported issue for 2003-2009 Hummer H2s. If left unresolved, it can cause improper HVAC (heating, ventilation, air conditioning) temperature and air delivery. Many owners of the affected units had to spend around $50 to $70 on diagnosis alone to address the problem.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Gas Cap Issues<\/h3>\n\n\n\n<p>A loose or worn gas cap is a common complaint for the 2003-2009 model years. The check engine light usually illuminates to mark this issue.<\/p>\n\n\n\n<p>However, a gas cap problem is not the only issue that can activate the check engine light. So if you encounter this symptom, it&rsquo;s best to take your vehicle to your mechanic for proper diagnosis. Here&rsquo;s a <a href=\"https:\/\/www.carparts.com\/blog\/can-a-loose-gas-cap-turn-on-the-check-engine-light\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"guide\">guide<\/a> on how to tell if your <a href=\"https:\/\/www.carparts.com\/gas-cap\/hummer\/h2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"gas cap\">gas cap<\/a> is the one triggering your H2&rsquo;s check engine light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Low Oil Pressure<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"699\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia-1024x699.jpg\" alt=\"2005 2007 Hummer H2 from Wikimedia\" class=\"wp-image-45772\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia-1024x699.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia-300x205.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia-768x524.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia-150x102.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2005-2007-Hummer-H2-from-Wikimedia.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Some 2006 Hummer H2 owners have reported loud knocking sounds along with coolant loss.

Repairs for this type of problem can reach up to $7,000.<\/p>\n\n\n\n<p>Many 2006 Hummer H2 owners reported loud knocking sounds along with coolant loss. Most of them replaced their <a href=\"https:\/\/www.carparts.com\/oil-pump\/hummer\/h2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"oil pump\">oil pump<\/a> to solve the issue, but, in most cases, the problem persisted. Some drivers unfortunately had to get their engine replaced in order to fix the issue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Engine Stalling<\/h3>\n\n\n\n<p>Some 2003-2006 Hummer H2 owners have complained that their SUV is prone to engine stalling and low idle speed. Servicing the throttle body usually corrected the issue. <a href=\"https:\/\/www.carparts.com\/throttle-body\/hummer\/h2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Throttle body\">Throttle body<\/a> cleaning usually costs anywhere between $230 to $290.<\/p>\n\n\n\n<p>If you encounter this problem with your Hummer, note that many underlying issues can cause your H2 to stall. So it&rsquo;s best to take your vehicle to an auto repair shop for proper diagnosis.<\/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\">Steering Wheel Position Sensor Failure<\/h3>\n\n\n\n<p>A steering wheel position sensor that failed after around 58,000 miles is another common complaint among many H2 owners. A service stability message usually accompanies this issue.<\/p>\n\n\n\n<p>The steering wheel position sensor or <a href=\"https:\/\/www.carparts.com\/steering-angle-sensor\/hummer\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"steering angle sensor\">steering angle sensor<\/a> (SAS) plays a crucial role in ensuring predictable steering.

Upon inspection, mechanics found a fault in the <a href=\"https:\/\/www.carparts.com\/turn-signal-switch\/hummer\/h2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"turn signal switch\">turn signal switch<\/a>.<\/p>\n\n\n\n<p>Fortunately, replacing the faulty switch usually resolves this problem. Parts may cost you anywhere between $40 and $120. Labor costs may set you back by another $80 to $100.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Restricted Secondary Air Injection Valve<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"570\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-1024x570.jpg\" alt=\"2006 Hummer H2 Wikimedia\" class=\"wp-image-45763\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-1024x570.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-300x167.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-768x428.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-1536x856.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia-150x84.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/2006-Hummer-H2-Wikimedia.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Some 2003-2006 Hummer H2s can develop faults in their air injection valves.

Mechanics recommend replacing both valves at the same time, even if only one valve is faulty.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fuel Level Sensor Failure<\/h3>\n\n\n\n<p>Several 2003-2004 Hummer H2 owners have also complained about <a href=\"https:\/\/www.carparts.com\/fuel-level-sensor\/hummer\/h2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel level sensor\">fuel level sensor<\/a> malfunction. Their faulty sensor recorded incorrect fuel tank level readings, resulting in erratic fuel gauge behavior. Most of them noticed that their gauge read &ldquo;full&rdquo; then &ldquo;empty&rdquo; again in a short span of time. Some drivers also noticed changes in their usual gas mileage.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Fuel Pump Level Sensor Testing and Replacement\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/0eRXw2M-gEQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>These are only some of the issues your Hummer may develop as it puts on the years. By doing your research and carefully inspecting the vehicle you intend to purchase, getting this SUV should come with little risk. More importantly, you can maximize your Hummer&rsquo;s service life by following its maintenance schedule and replacing faulty or worn-out parts immediately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hummer H2 Years to Avoid<\/h2>\n\n\n\n<p>The Hummer H2 years you should avoid are the 2003, 2004, and 2006 models.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2003 Hummer H2<\/h3>\n\n\n\n<p>The 2003 Hummer H2 had its share of issues, mainly because it was the first production year. Some problems that hampered this year include premature tire wear and accessory belt tensioner failure.<\/p>\n\n\n\n<p>Tire wear is a safety hazard, as you may lose control on the road. If you drive this model year, make it a habit to check tire alignment and rotate it properly.<\/p>\n\n\n\n<p>A failing belt tensioner will cause the belt to slip, causing accelerated wear on belt-driven accessories. Regularly inspect the accessory belt tensioner to prevent breakdowns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2004 Hummer H2<\/h3>\n\n\n\n<p>Unfortunately, the second iteration of the H2 had similar problems to the 2003 model. In addition to tire wear and belt issues, the 2004 H2 reportedly had issues with its air suspension system.<\/p>\n\n\n\n<p>To make sure that your suspension system stays in tip-top shape, it&rsquo;s best to take your vehicle to a mechanic for professional advice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2006 Hummer H2<\/h3>\n\n\n\n<p>Lastly, 2006 is arguably the worst year for the H2. It had major causes of concern, such as knocking noises and coolant loss caused by oil pressure problems. Avoid this model year if you don&rsquo;t want to spend on costly repairs and deal with potential engine damage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get Replacement HVAC Mode Door Actuator Delivered to You<\/h2>\n\n\n\n<p>Whether you own a Hummer H2 or another model, driving your vehicle becomes unpleasant if the HVAC mode door actuator fails.
