HI, This morning after I backed out of my drive way, I applied the brake very lightly, no Hill hold appeared and then switched to Drive, NO NOISE!!!! Now I think I know what created the noise, please correct me if I am wrong. I think the Hill hold locked the gear, and so when I switched to drive, the noise is due to the unlocking of the gear from brake to drive. The noise also happens when I press hard or slam
on the brake due to a yellow light, hill hold appeared and locked the gear, so when I accelerate the car, the noise is due to the car try to unlock the gear from brake to drive. So to avoid the noise, I think I will apply the brake lightly on flat road. On hilly road, I think may be hill hold can help preventing the car from rolling. I am so happy that may be I do not have to bring my car in for service after all. I will try again this afternoon after work to see if this is still the case. I appreciate so much you take your time out of your busy schedule to provide very helpful and useful information to anyone out there who need help!!! Thank you!!
