As a result, the engine locked, and the contact was unable to start the vehicle. The failure recurred numerous times. The vehicle was not diagnosed or repaired. The contact also stated that during rainy weather, water entered the vehicle from the drain holes on top of the vehicle. As a result, the interior of the vehicle and the air bag were wet.

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.

H3 5-cyl

  • 105,000 miles


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.

After heavy rain excessive amounts of water pool inside vehicle. Drain plugs have been cleaned out multiple times. Although water continues to lay inside the track of the moon roof as well as drain onto the floor and sometimes onto the driver's side seat (depending on how the vehicle is parked). Based on the forums regarding H3's this appears to be a common problem. Why hasn't GM done anything to resolve it"?"

H3 |drainage problem I paid to have it fixed a year ago and it is blocked up again. My wife had the same problem with her H3. I have had cars and trucks and have never had this problem before with there sun roofs. I know I'm not the only one out here that's had the same problem. When at the dealership one of the shop mechanics said the design was a poor construction and design.the company should be doing something about there design and fix it or have a program to keep them from flooding. It could lead to electrical problems. Do to the water running down over the lower panels. I'm not happy paying to have it fixed again. This is just a bad design on GM part.

The side trimming near the roof racks are cracked, the gaskets near the rear of the roof racks are coming apart, and the trimming on both sides of the vehicle near the windshield are coming off and faded. The best way for me to describe what is going on with my vehicle is by presenting some forums that I read about.............. www.gmhummer.com/forums/showthread.php"T=796 www.hummerforums.com/forum/showthread.php?T=16421 www.elcovaforums.com/forums/showthread.php"T=20479 townhall-talk.edmunds.com/direct/view/.F0E3B5A apparently, I am no the only one who is having issues with this. Not only is this issue costly, but situations like this should not be of the customers fault when the vehicle has been taken care of as it should. Especially if it is only 4 years old. Molding should not come off a vehicle in this manner as it could eventually come off and damage someone else's property as debris while driving.

I own a Hummer H3 2006 model. I purchased it brand new. No accidents. The roof pools water because of a faulty drainage system. The water then comes out through the roof in large amounts and through the side walls and emergency brake. This can cause an accident due to the large amounts of water spilling onto the driver, or an electrical fire or mechanical malfunction. It can also cause mold in the interior due to large collections of water stagnating. This is a known issue that is recorded in GM forums - yet there is no recall for the faulty drain pipes.
