Question about 2002 Buick Park Avenue

1 Answer

When stopped, there is a motion in the back much as if the car has been bumped. Any ideas?

    It feels like a few quick pushes from the back while the car is at a dead stop. Although I thought it might be an engine misfire, I had the 100K tune-up and the problem persists. The car feels fine on bumpy roads, so I kind of disregarded the shocks/struts as a source of the problem.

    Thanks for taking the time to think this through and share your considered opinion.

    All the best . . . .

    Notice it change as fuel level in tank does? Or rear shocks/struts getting week. Does it bounce up & down, or just feel like a quick push from rear and back end of car stays steady? How does rear of vehicle react on bumpy roads?

Sounds like an intermittent loss of power to the instrument cluster to me. Remove the instrument cluster and inspect the electrical connectors on the back of the cluster.

I can't open the hood on my 2003 forester--help

Is the cable broken? If not have someone pull firmly and steadily on the release handle while you strike the hood. Make a fist and use the fleshy area oppisite your thumb and a "hammer" motion not a punch. Use common sense not to dent the hood but you can pound it pretty firmly before it will dent the hood.
When you have the hood open be sure to lubricate the latch. Spray grease is best but WD-40 or similar is better than nothing. Also lower the bump stops for the hood. They are located in the hood or on the core support. I don't know about your Subaru but most cars built in the last 15 years or so you can rotate the bump stops with your fingers. If you have to set them so low that the hood looks bad then you have to adjust the height of the latch.

Loud popping noise when turning or hit bump/ pot hole

look at the rubber grommets and end rubber on the stabilizer bar .. also check the top of the strut tower (under hood). they sometimes rust out allowing some free motion and eventually complete failure .. look for even slight motion there when the car is rocked ..
