#3 of 6 2010 outback vibration
Mar 14, 2012 (3:54 pm)
Bought a 2010 Outback that vibrates like a washing machine on spin cycle when you are in idle..Then it will try to die out and shake... I bought it 4 months ago and tomorrow will be my forth trip back to the dealer... It is worse when it's above 70 degrees outside, drive long than 2 hr. on highway or run air conditioner. Any suggestiions?

How many miles are on it? Is your "check engine" light on?

No engine light is not on... 25K miles. I bought it with 19K mi on it 4 months ago. The mechanic at the dealer witnessed it, passengers in the car with me commented on the vibration.. It gets worse as the outside temps get above 65 degrees. I bought the car in Late Oct. 40 degrees out and dry...it ran perfect. Once it started getting hot and you used the air conditioner it started this vibration in idle. And it trys to stall out if you've been driving at highway speeds the car gets worse..shakes and really acts like ti will stall.. So you have to keep foot on break and give it some gas at a long light or it will die. It goes in to dealer for the forth time tomorrow... I am very unhappy with this car..Lemon... I own a Toyota Avalon with 145K miles that's 12 years old and still runs perfect... sigh...should have bought another Toyota.

Okay; with that few miles, there's little chance there is a spark issue. That said, I would do three things (at the same time): 1. Check to make sure the cam, crank, and knock sensors are all firmly connected. 2. Disconnect and reattach the mass airflow sensor; perhaps also spray the sensor itself (inside the intake plumbing) with a sensor-safe cleaner. 3. Disconnect the battery for ~30 minutes, or disconnect and depress the brake pedal for a few seconds, to reset the ECU memory.
That aside, if you have taken it in to the dealer several times with no resolution, it does fall into the lemon category - every manufacturer has them, it's just a matter of who is unfortunate enough to end up owning that particular specimen. Definitely look into your state's laws on the subject in order to fully consider your options.
