When the car is idling, there is a strong smell of exhaust fumes coming out of the air vents. The smell dissipates when the car is in motion. The vehicle has been checked for any leaky exhaust pipes or gaskets but nothing has turned up positive.

In a document dated August 2015 I received a safety recall for my Hummer H# 2006. "General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2006 model year Hummer H3. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety a D continued satisfaction with our products, " important * your vehicle is involved in GM safety recall 15042 * parts to repair your vehicle are not currently available. When parts are available, we will send you another letter asking you to contact your GM dealer to arrange a service appointment. * this service will be performed for you at no charge." To date, I have not received any correspondence from either the manufacturer nor GM. The recall letter advised me to contact you if I was not satisfied that they had done their best to remedy this condition without charge and within a reasonable time. I certainly am not satisfied that this matter has been resolved within a reasonable time. I am afraid to drive my vehicle for fear it will burst into flames due to the problem described to me. However, I have only one vehicle and public transportation is not reliable in my area. I am beginning to wonder if the parts to repair my vehicle are ever going to be available, and further, if I will ever receive the promised second letter telling me to set up an appointment with my GM dealer to get my vehicle repaired.

There is a known issue with this vehicle leaking I noticed it when it was raining that rain would leak through the on star microphone as well as through the front the driver and passenger doors and make the carpet like a sponge: Https://youtu.be/ennnfwkhqwo the video attached to this link shows a prime example. If you read the comments it would show many customers of been affected with the same exact model vehicle. Also this video shows another example of water leaking through the on star microphone. Https://youtu.be/aqhyfoosmxg it is too expensive to have to pay $130 for them to diagnose a manufacturing flaw that multiple owners are going through. Please set a recall for this vehicle for them to resolve. Again it is a 2006 Hummer H3. Thanks in advance.

Very very common problem with GM products and excessive problem with H3 heaters. You smell something burning in your vehicle then your heater fan starts fluctuating and ultimately stops. There are reports that the dealership will fix the burnt plug, but it won't fix the problem, it'll burn up again. Now I have no heater in January in Ohio this should be a recall !!!!!!!!!
