Both rear leaf springs broke right at the front "spring eyes", causing the rear to shift towards the back of the vehicle, thus activating the emergency brake and causing the vehicle to become inoperable. I've read other similar complaints on the vehicle that shows that this the leaf spring design was clearly a manufacturer defect.

- What is wrong
- Gm is recalling certain model year 2006-2009 buick, lucerne; cadillac dts; hummer h2; model year 2008-2009 buick enclave; cadillac cts; model year 2007-2009 cadillac escalade, escalade esv, escalade ext; chevrolet avalanche, silverado, suburban, tahoe; gmc acadia, sierra, yukon, yukon xl; saturn outlook; and model year 2009 chevrolet traverse vehicles equipped with a heated washer fluid system (hwfs). A recall was implemented in 2008 to add a fuse to the control circuit harness to address the potential consequences of a printed circuit board (pcb) electrical short. However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. The significance varies from minor distortion to considerable melting of the plastic around the hwfs fluid chamber.
- Risk
- It is possible for the heated washer module to ignite and a fire may occur.
- Remedy
- Dealers will permanently disable and remove the heated washer fluid module. An updated page for the owner manual will be provided and inserted in the owner manual to document that the feature has been permanently disabled and removed from the vehicle. The safety recall began on june 11, 2010. Owners may contact buick at 1‑866‑608‑8080, cadillac at 1‑866‑982‑2339, chevrolet at 1‑800‑630‑2438, saturn at 1‑800‑972‑8876, gmc at 1‑866‑996‑9463 and hummer at 1‑800‑732‑5493 or at the owner center at www.gmownercenter.com.

What 2009 Hummer H2 owners say
Most recent owner complaints, unedited.
Since august of 2009, having problems with engine/transmission. Vehicle "died in flight" in august, vehicle coughs, stutters, and stalls out every day at first start-up, and I'm experiencing harsh shifting daily. I'm advised there is no resolution to the daily stall-out problem even though the vehicle has been in to the service department four times since 8/6/09. On last visit to service department I was advised that "gm is aware of the problem but has no fix for it" (case #11074714).
