Boy have I…

I have been dealing with this all winter. This year LA has been particularly rainy. I first noticed my driver floor flooded last January 12 after hearing water sloshing at a stop. I took it to Pasadena Hummer and 8 days later got it back having all the marker lights on the roof sealed.

February 11 there was more sloshing and the carpet was flooded again. I took it back to Pasadena Hummer where they re-sealed the windshield. That took 5 days.

I thought that was it since they said they had actually traced the leak to the windshield.

February 19 there was a good hard rain while my truck was parked outside at work. It sat in the rain for several hours before I went to lunch and checked the floor. It was dry so I thought the leak had been fixed. I pulled out of the parking lot and saw a nice puddle about 90 feet across and 4 to 6 inches deep. I hit that and sprayed water at least 20 feet across the sidewalk. I had a great time until I looked down and saw that I now had about half of an inch of water sloshing around on my floor. I was now convinced that the leak was not from the roof. I had read on this forum that Cerritos Hummer had great service so I decided to try my luck there.

I took my truck to Cerritos Hummer on Feb 21. John, one of the service consultants, explained that he had several H2’s in thr shop that were leaking from the firewall seams and that GM had people out here from back east working on a fix but they were unsuccessful so far. They gave me a rental and my truck was there for 3 days. I did have other work done, including an update to the software that I had seen discussed in another thread.

When I picked up my truck, there was still a half inch of water on the driver floor and the truck had a musty smell. The best they could do was to vacuum out the water and send me on my way. I was told that my VIN had been sent to GM and they would call me if/when a fix for the leaking firewall was issued.

When I got home I pulled back the carpet to dry the pad. I looked for evidence of water from the firewall and from the rubber boot in the door jam having seen a post about a leak from there. I found no indication that water was coming from the firewall or from the rubber boot in the door jam. Also, by the amount of water that flooded my floor in the short time I drove through that puddle I figured that the leak must be quite large. What I discovered was a plug on the driver’s floor. I thought this must be the source of the leak so I covered it from underneath with Rigger’s tape (like duct tape but stronger) and made arrangements to go back to Cerritos Hummer and have it sealed.

I also looked at the passenger side to see if there was a plug there since I had no water on that side. I found there was a hole but it had been sealed at the factory even before the painting process with a metal plate and body sealer.

March 7, Cerritos Hummer sealed that plug and confirmed that they could not find any indication of water leaking form the firewall. They even left the Rigger’s tape in place. I picked up the truck on March 10 and pulled back the carpet. The pad was still damp and I asked why they did not think it necessary to dry the pad. John then offered to order a new pad. It has come in but I have not had time to have it installed yet.

We had another hard rain the night of March 22. I drove for a couple of hours on the Freeway to Corona and back. The next day I pulled the carpet back and found the pad was sopping wet and water seemed to be coming from the center area of the truck under the driver’s seat. I could not pull the carpet back any further without taking out the seat. I could not find any other obvious points of leakage from underneath the truck and the area by the firewall and the door were dry.

I took the truck to Cerritos Hummer March 24 and said I think it is still leaking. The plan now is to install the new pad next week, inspect the floor with the seats, carpet and pad out, and see if there is any pooling or obvious leaks. Then, drive it in the next rain and see if the new pad gets wet.

So yeah, you can say I have heard of issues with taking on water in this location.

The first 3 pictures are of the plug on the driver’s side. The last two are the sealed hole on the passenger’s side from inside and from underneath.

BTW…what the f**k is fever talking about?
