  • 50,000 miles


The contact owns a 2006 Hummer H3. While the vehicle was parked, the contact noticed water on the front passenger side floorboard. In addition, the vehicle failed to start and all the gauges and meters on the instrument cluster provided incorrect readings. All the warning lights illuminated. The vehicle was taken to a dealer multiple times where it was diagnosed that the drain pipes for the sun roof needed to be cleaned. The vehicle was repaired on several occasions; however, the failure persisted. In addition, the VIN was included in NHTSA campaign number: 15V421000 (visibility); however, the part needed to repair the vehicle was unavailable. The manufacturer was notified of the failure. The failure mileage was 50,000. VIN tool confirms parts not available.

I have owned this truck since 2009, and it seems to be a common problem with the sunroof drain tubes clogging. When my vehicle was under warranty, and was going in for it's scheduled pmis I would have them blow the drain tubes out with air, but the clogging is now becoming more frequent, and the water if not removed can cause havoc with the cloth, electrical & flooring. Last week I had a mildew smell because of all the rain we have had, and the water built up in the sunroof drain area. These tubes are a design flaw, and this should also be a recall, as the water will be the main cause for problems in this situation.

The contact owns a 2006 Hummer H3. The contact stated that rain water began to flood the vehicle while driving. The vehicle was taken to the dealer for a diagnosis. The contact was informed that due to the drain lines being too small, they would need to be retro-fitted at the consumer's expense. The manufacturer was notified of the issue and offered a credit towards her next purchase of one of their newer vehicles. The vehicle was repaired at the owner's expense. The failure and current mileages were 105,000. The consumer stated the entire vehicle had to be stripped, treated and dried. The issue was the drain lines in the sun rood pan.

The contact owns a 2006 Hummer H3. Due to heavy rain conditions the sun roof began to leak. The contact took the vehicle to the dealer who stated that the drain in the sunroof was clogged. The dealer unclogged the drain and within a few months the sunroof started to leak again. The contact took the vehicle back to the dealer and the drain was unclogged again; however, the sunroof continued to leak. The sunroof seal was being replaced by the dealer when the complaint was filed. The contact called the manufacturer regarding the complaints on the leaking sunroof. The manufacturer stated that the leak was due to the clogged drains. The contact was concerned that the manufacturer did not issue a recall since the failure was a manufacturers defect. The failure mileage was 30,000.

Hummer H3 complaint first, the 06 Hummer H3 sunroof has leaked on two separate occasions about a year and a half apart, most recent this may-June. Water leakage inside on the front side window panels and floor panels and floor. Moore Cadillac-Hummer told me that clogged drains were the cause. I think the seal must be defective otherwise the rain would not get in. The first incident was covered under warranty; this past incidence the warranty had just expired so I was charged $100 dollars. I have a feeling that it's going to happen again. I've never had this happen on other cars, the seals never leaked unless I left the roof open. Second, the A/C fan blower recently went out, this July-August, my local mechanic said that the R & R blower motor resistor and resistor wire harness burned out. I've read this on several blogs, that this will happen repeatedly due to the design and resistor capacity. His service fee to repair is $300 dollars; about $170 for labor and $ 130 for parts, which I think is too high. I haven┐T taken it to the local GM dealer (moore Cadillac-Hummer), though I purchased it from criswell in gaithersburg, md, since I probably could not afford their cost.
