J.D. Power gave its latest model, the 2010 Hummer H3,&nbsp; a reliability score of 3 out of 5. Older models also have good reliability ratings.

Just like other SUVs, it can develop problems due to faulty or worn-out parts as it gets older. Here are some of the most common Hummer H3 issues across its model years:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cracked Radiator<\/h3>\n\n\n\n<p>Many 2008 Hummer H3 owners have complained about coolant leaks caused by a cracked radiator. According to reports, this is a common problem for the model year. Fortunately, replacing the faulty radiator solved the issue on most affected vehicles. A <a href=\"https:\/\/www.carparts.com\/radiator\/hummer\/h3\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"replacement radiator\">replacement radiator<\/a> can cost anywhere between $100 and $750 plus labor costs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A\/C or Heater Problems<\/h3>\n\n\n\n<p>A\/C and heater issues are another common complaint about the 2008 Hummer H3. Many owners have reported that their HVAC (heating, ventilation, and air conditioning) <a href=\"https:\/\/www.carparts.com\/hvac-wiring-harness\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"harness\">harness<\/a> burned out at around 90,950 miles.

According to reports, the fuel level sensors of the affected vehicles may fail, causing erratic fuel gauge operation.

Repairs for this type of problem can cost up to $1,650.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Leaking Valves<\/h3>\n\n\n\n<p>2006 was the worst year for the H3 because most of the problems reported for this model year are related to the SUV&rsquo;s engine. Many owners have complained that the valves in their H3&rsquo;s <a href=\"https:\/\/www.carparts.com\/cylinder-head\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"cylinder head\">cylinder head<\/a> started leaking at about 87, 750 miles.
