When driving the vehicle, this mostly occurs on surface streets, the stabilitrak lights will come on and then shut off. The problem has progressed and the lights will now come on and then black out the dashboard. The car has even completely lost power while driving and then come back on. This is quite terrifying! The battery has been replaced and is brand new. The only time the car lost power on the highway was when the car was moving at a slower rate of between 30-50 MPH.

Electrical system: ignition
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.
- Risk
- If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.
- Remedy
- GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1‑800‑458‑8006 (Cadillac), 1‑800‑222‑1020 (Chevrolet), or 1‑800‑462‑8782 (GMC).

Tl* the contact owns a 2012 chevrolet suburban. While driving 45 MPH, the radio and dashboard lights blinked off and on and the doors locked and unlocked continuously. The contact also stated that the engine was acting like it was stalling. The contact stated that the ABS worked intermittently. The contact was able to pull the vehicle over and shut it off. When the vehicle was restarted, the engine revved highly as if it were in neutral. Upon taking off, the vehicle hesitated as if it would stall again. The vehicle was not taken to a dealer. The manufacturer was made aware of the failure. The failure mileage was 103,000.
Tl* the contact owns a 2012 chevrolet suburban. While attempting to refuel the vehicle, the fuel pump seized several times.

While just starting to accelerate, the radio shut off, the automatic locks started to go up and down, then the engine light came on and the engine stopped running. I put the truck in park, shut of the engine and restarted without issue 5 minutes later. Two days later, the same thing happened, only this time, when we went to restart the truck, it seemed as though the battery was dead as no dome lights would come on and the fob would not work the door locks. 3 hours later when the tow truck operator showed up, the truck started right up. This has happened 5 times since april 6th. The last time, the engine shut off as I was crossing a four lane highway. Luckily, we were not hit. Seeing multiple reports of the same issue make me think it is not unique to my vehicle. "dead battery" that isn't dead... "locks going up and down", "sudden deceleration". Does someone have to have an accident and be killed for anyone to take action on this issue?? Why not be proactive and start investigation before someone gets killed??
Having issues with various warning lights will come on in the dash (seat belt, traction control, air bags), the radio will go dead and the headlights will flicker, and it loses power and steering for a few seconds. It seems to happen when I'm applying brakes or turning corners and just at random times. I'm very worried about this happening for extended periods of time, especially on hard curves when you lose power. The dealer is reporting that it is a ground cable issue and want us to cover the entire cost of repairs. Updated 09/15/15

Low miles owner, garage kept, after several days of non-use, ie-parked in garage, vehicle will not start due to a dead battery. Baytown (craft) dealer could find nothing wrong. Current mileage 24k, still does same thing, if vehicle is not driven almost daily, the battery will go dead for zero reason and no one a chevy know why or what. Have had vehicle at dealer several times and nothing ever fixed.
On two recent occasions my suburban has failed to start (battery dead). I went to an auto parts store, they tested the battery and said it was good. Why is my battery going dead? Both instances are the vehicle is set on accessories and the radio was working. In both instances the battery would not turn over the engine.
