Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The vehicle would randomly performing in very odd manners such as stalling while driving down the highway, electrical systems (lights, stereo, etc) turning off and on randomly, reducing speed ignoring accelerator position as well as many others. Several visits to different mechanics found no issues with the vehicle. While sitting on the side of the road at one point waiting for a tow truck I noticed that the passenger floor was soaking wet and we had not had rain for many days. After doing my own investigating I found that the drain pan for the A/C condenser is located inside the car behind the stereo just to the left of the glove box. The drain pan has a hose that routes through the firewall and drains onto the ground from under the hood. This drain hose became clogged and as a result all of the water from the A/C condensation was overflowing and draining directly onto the ECU and then onto the passenger floor. This water was causing the ECU to misbehave which was creating a dangerous situation but by time the vehicle was taken to a mechanic the water had dried and the car was behaving properly. Once the drain hose was cleared there were no further problems. After checking on some Suzuki forums I found a couple others that had the same situation arise. It's a fix that takes less than a half hour and requires no parts but not one that mechanics know about and creates a dangerous situation with the computer acting unpredictably and frequently causing the car to stall in the middle of the roadway.
