Ok...I have read many posts online about the SHAWD light coming on. And there are endless people writing about it, everyone seems to have a different fix, or does not have a clue why the light comes on. I think its because unless you really pay attention to the variables, you would never know it could be happening from this...
I have a 2007 RDX, with 153K miles. The car runs great, as I maintain it very well. The SHAWD light along with the check engine light came on as I was driving home from Atlantic City, NJ. I usually visit AC, twice a month or more. I rarely fill up my gas tank prior to going, thinking I can always get gas on the way home. I usually get gas from the same place all the time. I use Mobil, sometimes BP. I do not put cheap gas in my car. The RDX calls for super, 93-94 octane fuel. There is no way around this.
The SHAWD would only come on as I drove home from Atlantic City, back towards NY. I found this very odd, as it has done this 6X so far. If you restart the car the SHAWD light always goes away, however the check engine light will go away after A few starts. Whatever the factory has set that up. This was insane, because the SHAWD never comes on in NY. I was thinking at first how on earth can the light come on only as Im driving home from AC, and never while Im going. I was thinking maybe the air is more dense, etc. Then I realized, as I come home from AC, I always stop for gas...I fill up with Sunoco. All the gas stations going from NY to the Jersey Shore are all Sunoco. As they must have a contract. This makes me think that the gas they sell is either not super...I use 93, however that does not mean just because I tell them to use 93, I get 93. I feel a loss of power after I fill up. Either these cars are very sensitive to the gas you use, or these Sunoco stations are crooks. They may figure, lets sell cheap quality gas, maybe with a higher ethanol than allowed. And since these cars have a turbo, once you hit the gas pedal, the car is not burning the fuel the right way, and triggers the light to come on. If I dont go to AC, the SHAWD never comes on. As I always use Mobil gas. If your car is triggering this light and you fill up at Sunoco, or Pilot, or some cheap gas station, try using Mobil or BP, and see if your light still comes on. If it doesnt there is the problem...
