general problems of the 2009 GMC Sierra 1500

Tcm and electrical transmission grounded out tcm in my research a lot of people are having issues with these. Dealers are of no help “backordered” so having to rebuild them. This is an expensive failure!.

While driving on Saturday, July 29th, I went to make a right turn @ intersection of nottingham way onto ledo rd. The vehicle started jerking and suddenly shutoff. I had no power steering, no power brakes. I had to manually steer and stop the truck into the median, while avoiding oncoming traffic. I got the vehicle to stop. I tried to restart and the engine turned over, but would not start. I contacted the local Chevrolet dealership, and was told they don't work on anything older than 2013 vehicles. I had the truck towed to the house. After further investigation, there was a service bulletin 14515b, that replaced 14515a. The safety recall stated chassis electronic control module internal contamination. So gm is aware of this issue, that could have caused an accident. The local dealership is denying that my truck is involved in this recall. They knew of the problem and never contacted me about this issue. This is a severe safety issue. Gm should be responsible for repairing a defective control module as they knew of contamination as of January 2015. This almost cause multiple head on collisions.

Dashboard instrument panel all lights and gauges goes out while driving down the road when vehicle is turned off a clicking noise is made in the dash. This issue causes when driving down the road, not knowing the speed because the speedometer is out or how much gas the vehicle has, or any other readings, and at night all lights go out, not able to see while driving down the road.

My dashboard instrument cluster has been going in and out since iv owned the vehicle in February of 2022 and iv replaced fuses did the reset test and everything on it and nothing I can’t see my speed rpm’s gas gauge nothing all the lights are on but nothing else moves or comes on I can’t even tell the speed I’m going or if I even have enough gas in the truck to even make it to a store I have add electrical problems since day one with the truck and replaced so many fuses for everything and nothing work’s really even my alarm system don’t work.

Transmission control module since the summer of 2020 the vehicle has at least half a dozen times, without warning, experienced the following symptoms (most recently July 27, 2021 when I captured it on video). 1. Power door locks begin cycling open and closed 2. Intermittent chime operation 3. Transmission locks into a single gear and won't shift or will shift harshly 4. Gauges fluctuate 5. Traction control and stabilitrak turn off 6. Service traction control and service stabilitrak messages appear 7. Transmission position indicator disappears.

Tl the contact owns a 2009 GMC Sierra 1500. The contact stated that the vehicle hesitated and stalled without warning. The vehicle was taken to serra Chevrolet Cadillac Buick GMC (189 stonebridge blvd, jackson, TN 38305, (888) 380-6149) where they replaced the fuel pump module, cleaned the throttle body, replaced the fuel pump sending unit, and reprogrammed the module. The contact stated that the engine power was reduced due to lack of communication with the fuel pump module. Shortly after the repair, all of the warning indicators flashed, which had not occurred prior to the repair. The manufacturer was notified of the failure. The approximate failure mileage was 103,000.

Tl the contact owns a 2009 GMC Sierra 1500. While driving 65 mph, the speedometer and the tachometer gauges fluctuated up and down, the air bag and transmission indicators illuminated, and the engine seized. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was notified and informed the contact to call a dealer. The failure mileage was approximately 47,540.

Vehicle will randomly show a warning signal for stabiltrack turning off. Then it will cycle door locks up and down, turn on the air bag light, abs light, and sometimes reduce power to 20 mph. It will also kill the vehicle gauges. Numerous trips to the shop have failed to correct the issue. A quick google search of stabiltrack 2009 chevy/GMC will show a ton of hits. Due to the safety concerns of these critical systems powering down, this is clearly a safety issue. This occurs while the vehicle is in motion, which makes it more concerning. This issue started with 66k miles and has persisted. Vehicle now has 96k.

Seatbelt recall. And tire pressue light contiue to come on.

All door locks are inoperative. They will not lock or unlock the doors with either the key of the door lock buttons. Just found this website-hence delay in reporting, did contact dealership-cost of repair is astronomical.

Tl- the contact owns a 2009 GMC Sierra 1500 500. The contact stated that when the vehicle was started the doors automatically locked as designed, however, when the vehicle was placed in the park position the doors failed to unlock. The contact had to manually unlock the vehicle. The failure recurred on several occasions. The vehicle was taken to the dealer and was diagnosed that the drivers and passengers side door actuators were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 47,000. Sw.

I'm having electrical/computer problems that started over a year ago and continue to increase. First, my speakers go off and on as they please. The driver side door speaker is the only one that stays on consistently, and it has nothing to do with hitting bumps or anything else. Second, my power looks have gone out. My key fob will still work them and they still lock and unlock when truck is moved between park and drive. But the buttons on the door do not work. I've replaced all the fuses, and still, nothing. Third, my cruise control is going out. On a long drive I used it for half and then the other half it wouldn't even try to come back on. A few days later it worked again.

The power door locks won't lock and unlock. I have already replaced one door lock mechanism at my cost. Now a second lock won't function. This is well known by gm. They refuse to recall it. This is a safety issue. Gm needs to repair these door locks.

My driver's door lock actuator has begun working intermittently. This is the second door lock actuator on my vehicle to fail, the first was replaced under warranty and the gm mechanic told me they have replaced numerous actuators. The vehicle automatically locks all doors when driven and unlocks when stopped however the faulty actuator does not always lock or unlock. These actuators have a long history of being defective and gm is aware of it but refuses to recall the faulty actuator even though they have literally replaced thousands of these units. These faulty actuators are a safety concern because in the event of an accident a door could fail to unlock effectively trapping the occupants. The faulty actuators are also a security concern because they could fail to secure the vehicle allowing anyone access to it's contents.
