About Hummer H2

Hummer H2 is a sport utility vehicle and sport utility truck manufactured by the AM General Corporation but marked by Hummer from 2002 to 2009. The first Hummer H2 was introduced in 2002 to replace the Hummer H1, which is wider, longer, lighter and taller with room for six or seven passengers than Hummer H2. But the Hummer H2 was the only one of the trucks to have the letters HUMMER between grilles. As a full-size SUV from the powerful General Motors Company, Hummer H2 was nominated for the North American Truck of the Year award for 2003 and had won Roll Hall Racing for several times.
Hummer H2 has two vehicle types: 4-door crew cab truck and 4-door SUV. As it was built under contact at the GMT913 platform, the front of Hummer H2 used a modified GM 2500-Series utility frame, the midsection was built alone and the rear section used a modified GM 1500-Series frame. Hummer launched a special 2009 Black Chrome Limited Edition version of the truck. From 2003 to 2007, Hummer H2 was powered by a 6.0 L V8 engine that could produce 325 hp and the engine was mated to a 4L65E 4-speed automatic transmission. Then from 2008 to 2009, powertrain was upgraded to a 6.2 L V8 engine that could produce 393 hp and a 6L80E 6-speed automatic transmission.

Hummer H2 Common Problems & Maintenance Tips

Even as a vehicle with military background, Hummer H2 could not get away from wear and tear due to exposure to harsh driving conditions and continuous operation. So you had better get to know about what consequences would appear once wearing process starts:
First, electrical issues. After all, Hummer H2 is a vehicle manufactured in 21st century, which means it must have equipped with many kinds of electrical parts and once electrical parts begin to wear due to long-time usage, electrical problems will not be rare. According to Hummer H2 drivers, the common electrical issues involving bad gas mileage, engine rough idling and sometimes, the vehicle would suffer from starting or loss of power while acceleration. If you can also find corrosion on the battery terminals and the Check Engine Light comes on, please make sure the H2 oxygen sensor and H2 battery cable are in good condition.
Second, brake system failure. I believe there is no need to repeat the importance of braking system because every driver is aware of. In such a giant item as Hummer H2, braking system could cause deadly accidents. Hummer H2 drivers told that after a long time of driving, the H2 brakes would become super noisy and respond poorly. At the same time, the brake pedals may pulsate and vibrate, which makes it difficult to apply braking action. Visible score marks found on the brake rotors plus all above symptoms are warning you to perform a thorough inspection on the H2 brake pad set and H2 brake disc.
It has never been an easy task to keep your Hummer H2 at the prime condition all the time. Besides the essential routine maintenance and getting any defective auto parts replaced, you have to take preventative measures in advance as well. The windshield wiper, for example, works to provide better visibility should get changed at least once a year no matter it is faulty or not. Other parts such as fog lights, headlights and seat belts should also be replaced in a regular basis. is a prime online store with OEM Hummer H2 parts at the lowest price in the market.
