Recall #09V154000 should have been performed on my vehicle according to the list of VIN #'s affected, but it never was and I was never notified of the recall. I purchased this vehicle the month before this recall was announced in 2009 and did not start having safety issues until after my new SUV warranty had expired (how convenient). Over the years, I have spent thousands of dollars replacing all kinds of sensors, relays, batteries and various other parts trying to alleviate the unsafe electrical and loss of power issues that this faulty part continues to cause. I have taken this vehicle to my local dealership on countless occasions, complaining that the vehicle intermittently: does not start, the engine suddenly dies while driving on the highway or turning a corner (becoming unsteerable and the brakes won't work), suddenly decelerates, door locks cycle rapidly while driving, the check engine light and other warning lights/alarms come on, headlights and dash lights suddenly shut off, windows or AC stops working, and now the fuel gauge only reads 1/4 tank when I just filled it up. I took the SUV to my local dealer again today, explained the intermittent electrical and loss of power issues and history again and asked why this recall had not been performed or was not scheduled to be performed at any previous time that I had brought the vehicle in for diagnostics or service on these related issues. The service manager admitted that the recall had never been performed, but denied the possibility of the FSCM causing any of these issues, regardless of the recall notice stating they were. He then refused to perform the recall and said I needed to pay $380 to have another diagnostic scan performed. Never scheduling/performing the recall when the SUV was serviced countless times for related safety issues as defined in the recall notice that they never mailed to me and refusing to perform the recall today is a violation of the US NTMV Safety Act and should have consequences!

Have owned since 2010. Have had the vehicle lose power while driving a couple of years ago. The throttle body was replaced. The vehicle idles rough (you can feel it idle but not all of the time). Dealership said they could not detect a rough idle issue. Later, another issue with the throttle body causing the check engine light and misfires in cylinder (have paperwork inside vehicle) replaced a sensor related to the throttle body. Last friday, march 2, 2018 driving on a crowded downtown street the tahoe began to idle rough again, to the point of the seat belts shaking and the engine sounded as if it were about to lose power again (been there done that). Arrived at work placed the vehicle in park and the traction control/stabilitrak message appeared that both were off, then the warning service traction control flashed then to service stabilitrak. I looked into the issue and called the dealer ship as well as the warranty folks telling them of the issue made appt for following day to bring in. Went to drive home, the check engine light is now on and the car is rocking and sounds like it might stall out in rush hour traffic. Limped the car to the closest dealer out of fear of an accident should the car shut down driving home. Researched online, found that this is an issue with a tsb issued # 11273 that noone has ever mentioned with the multiple times the vehicle has been repaired due to the issue listed in the bulletin that could have caused a devastating accident as I drive 5 - 6 kids to school every morning and can not imagine why this was not shared with me as an owner (registered with gms website with the VIN) so I am sure to receive updates for issues just like this, that no one has ever mentioned even though the repairs are identical to what is stated in the gm issued technical service bulletin # 11273.
