2009 Hummer H3 problems
The Hummer H3 is an off-road vehicle that was produced from 2005 to 2010 by General Motors. The smallest model of the Hummer lineup, it was offered as a 5-door SUV or a 4-door pickup truck known as the H3T. Unlike the larger H1 and H2 models, the H3 was not developed by AM General. It was introduced for the 2006 model year, based on a modified GMT355 that underpinned the Chevrolet Colorado/GMC Canyon compact pickup trucks that were also built at GM's Shreveport Operations in Shreveport, Louisiana and the Port Elizabeth plant in South Africa. While mechanically related to the Colorado and Canyon, GM claims they share only 10% of their components, with the chassis modified and reinforced for heavy off-road duties.
Powertrains
The H3 was launched with a 3.5 liter straight-5 cylinder L52 engine that produced 220 hp (160 kW) and 225 lbf⋅ft (305 N⋅m) of torque and was mated to a standard five-speed Aisin AR5 manual transmission or an optional Hydra-Matic 4L60-E four-speed automatic transmission. In 2007 this engine was replaced by the 3.7 liter LLR that produced 242 hp (180 kW) and 242 lbf⋅ft (328 N⋅m) of torque, figures that were revised in 2009 to 239 hp (178 kW) and 241 lbf⋅ft (327 N⋅m). Under revised EPA testing standards when equipped with either transmission this straight-5 engine achieved 14 mpg‑US (17 L/100 km) in the city and 18 mpg‑US (13 L/100 km) on the highway with a combined average of 15 mpg‑US (16 L/100 km).
Available solely with the 4L60-E automatic transmission, a 5.3 liter LH8 V8 engine producing 300 hp (224 kW) and 320 lbf⋅ft (434 N⋅m) of torque was added in 2008 for the Alpha model. The V8 version had lower fuel economy, estimated at 13 mpg‑US (18 L/100 km) in the city, 16 mpg‑US (15 L/100 km) on the highway, with a combined average of 14 mpg‑US (17 L/100 km).
In 2007, a H3X edition was added. It included the luxury package, 18-inch chrome wheels with unique center caps, chrome trim, chrome tube steps, a body-colored grille and a hard tire cover. The H3X also came with exclusive colors of Sonoma Red Metallic or Desert Orange Metallic.

Common 2009 Hummer H3 problems
Based on complaints from owners of the Hummer H3 2009, several common problems have been identified:
- Valve Seats Wear in Five-Cylinder Engines: Owners have reported abnormal wear in the valve seats of the five-cylinder engines, leading to low compression in affected cylinders, rough idle, and hesitation under acceleration. This issue triggers the ECM to store cylinder misfire codes .
- Pass-Lock Anti-Theft System Malfunction: The pass-lock anti-theft system tends to cause intermittent starting issues when it malfunctions. Replacing the ignition switch can resolve this problem, followed by a key relearn procedure to ensure proper functionality .
- Water Pump Leaks in 3.5-Liter Engines: The water pump in 3.5-liter five-cylinder engines is prone to developing cooling leaks before the vehicle reaches 100,000 miles .
- Automatic Transmission Slipping: Automatic transmissions in Hummer H3s are known to slip and develop rough shifting conditions, which can eventually lead to complete transmission failure .
- Heater Blower Motor Resistor Electrical Connector Overheating: An electrical connector that plugs into the heater blower motor resistor tends to overheat and melt, leading to electrical issues and potential safety concerns .
- Radiator Cracking: The radiator in Hummer H3s is prone to cracking in the upper area close to the core support. Replacing the OEM radiator with an aftermarket aluminum replacement is recommended for a permanent solution .
- Front Wheel Bearing Noises: Front wheel bearings tend to become noisy and develop play, especially in lifted Hummers with larger than OEM wheels and tires, typically before the vehicle reaches 100,000 miles .
- Power Steering Pump Failure: The power steering pump in 3.5-liter five-cylinder engines is prone to premature failure at low mileage, impacting the steering performance of the vehicle .
- TPMS Sensor Failures: Tire Pressure Monitoring System (TPMS) sensors are prone to failure, leading to the illumination of the TPMS light on the dashboard when malfunctioning .
- Clogged Sunroof Drain Tubes: Sunroof drain tubes are susceptible to getting clogged, causing rainwater to leak inside the vehicle. Regular maintenance to ensure these tubes are clear is essential to prevent water ingress issues .
What problems do the Hummer H3 have?
Leaking Valves
Some reported that their engine started to misfire multiple times. Several 2006 Hummer H3 drivers found out that their SUV was burning oil when they brought it to a repair shop. Some of them also had issues with oil leaks.
What years to avoid on Hummer H3?
Hummers are among the safest vehicles, with excellent safety ratings. The 2010 Hummer H3, for example, passed many damage tolerance tests, such as frontal and side impacts. According to some car complaints, the 2006 H3 was the worst version year in Hummer's 12-year professional life.
Is Hummer H3 a reliable car?
Most reliable vehicle I've ever owned!
Mechanically reliable, very safe, built solid, it will literally drive through anything without getting stuck! I own the H3 alpha with the 5.3L v8. This is a strong engine. I could not recommend the 5L motor.
Do Hummer H3 have transmission problems?
One of the most common Hummer H3 transmission problems is the complete failure of 3rd and/or 4th gear. This happens because one or more of the metal clutch discs inside the 4L60E 3-4 clutch pack can fail prematurely and prevent the transmission from engaging those gears.
