Fuel pump leak. our cabin fills up with exhaust causing myself and my 3 young kids (1,3,5) to start coughing, eyes and throat burning, headaches & a hard time breathing. confirmed by GMC dealer in concord & separate auto shop. They told us it had a recall and that they couldn't fix it after paying them to diagnose it since it was recall. Now GMC dealer is telling us that the problem and recall exists for other 2015 Yukon models but our VIN # Is not included and that's why they never fixed the problem that I've been complaining about since I bought the truck (dont remember exact purchase date but the vehicle was new and under warranty for years). I've taken it to the dealership 3 times for the same problem (exhaust smell in cabin) and they kept saying it's fine. Now it's so bad that we can't drive it because it makes us feel sick.

When sitting at a light, or stop sign vehicle acts as if it wants to cut off, check engine light is flashing, when I'm driving vehicle the check engine light stays lit. I did a scan of the vehicle and the code I got was p0303 which is for a cylinder 3 misfire. I have changed out the spark plugs and wires, also the ignition coil. I changed out the fuel injector for cylinder 3 and also the fuel pump actuator. Its still shaking, don't know what the problem is but I hope you guys can come up with what I need to do next. I've had to spend money out of pocket for this because its not under warranty.

July 26, 2016 we were in las vegas traveling on the strip and our vehicle loss power and died, it started up after a few minutes. A code was set for fuel pump pressure, then today we were in marna az, and our vehicle died while driving in town. A policeman followed us to find out what was wrong and we told him. To our surprise he has been having the same issue with his 2015 tahoe. He brought his vehicle to dealership and they told him it here was a problem with the fuel pump when the temp is too hot.
