Having an issue with a squeaking noise coming from the back of the car. It only starts to do it after about 5-10 minutes of driving. It's a loud squeaking noise and as far as I can tell I feel like it is coming from underneath the car in the rear.

The noise occurs up to about 1800-1900 RPMS when I'm accelerating or maintaining my speed. It also does if the road is somewhat bumpy, and after driving for a while if I put it in park and let it idle it will still do it on and off.

However, if I turn the car off and immediately turn it back on, and just let it idle... no noise occurs.

Anyone have any ideas what this could be? It's extremely embarrassing to drive around with this going on.

Any help appreciated.

From your description of all the different instances that this happens, it could be just about anything. Start with easy stuff like the trunk latch. If the latch is not adjusted tight enough it will give you a metal to metal squeak. If it feels like it's adjusted properly, then put a touch of grease on it anyway. While you have the back open check for loose stuff like the jack rubbing on the spare wheel, lug wrench etc. Beyond that look for exhaust rubbing on frame members or a brake backing plate coming loose. Slide under the car & start looking for loose stuff like exhaust hangers that are torn or broken & allowing pipes to rub. Have someone drive the car slowly while you walk/run alongside to make sure which area/side of the car this noise is actually coming from.

Do a full undercarrage visual inspection for any damage
from running over parking stops and the such.
It should look 100% OEM with no damage.
I would suspect your panhard bar is damaged
or the LCA mounting points on the axle are bent.
Examine the exhaust system for proper body to
tube clearance during full rear suspension travel.
This will take a lift and tools but its worth it to
find the 'squeek' that eludes you.
Could be the fuel pump going bad in the fuel tank.

Ok thanks both of you for the responses.

I will take a very good look under the car to try and find anything.
