TIME FOR A TUNE-UP?

Time for a tune-up?

Some vehicle sounds are no big deal, while others can be a sign of something more…sinister. Be sure to let your GMC Certified Service Spirit Whisperer know if you’re experiencing any of the following.

SQUEALS
A loud squeal on acceleration could mean you’ve woken a poltergeist from everlasting slumber. But it could be a sign of a loose or worn accessory drive belt, which helps power key vehicle components. If squealing persists, especially when your vehicle is just warming up, see your GMC Certified Service experts. If replacement is necessary, your timing belt could also need replacement (if equipped). An engine can be seriously damaged by timing belt failure, making it extra important to stay on top of manufacturer-recommended replacement intervals.

CHIRPING
If a high-pitched chirping noise disrupts your travels and no ominous bats are observed, brake pads could be the culprit. Many GMC vehicles come equipped with a small, thin metal tab attached to the brake pad to act as a warning indicator when the pad’s friction material – the key element in helping slow and stop your vehicle, is worn and needs replacing. When this tab makes contact with the brake rotor, it could make a chirping noise on brake application, letting you know it’s time to ask your GMC Certified Service advisor about a new set of brake pads or other brake system work.  Some GMC vehicles may be equipped with a brake pad life monitoring system that will display the amount of brake pad left.

SQUEAKS
Should you hear squeaking, first check to make sure you’re not driving on a rickety bridge toward a haunted mansion. If not, your vehicle’s bushings may be the culprit. Bushings are the most common joints in a suspension system and can squeak if the rubber tears or dries out. Squeaking can also occur when a suspension component starts to rotate inside the metal sleeve of a broken bushing, or of a bushing that’s been torqued incorrectly. Your GMC Certified Service experts can help you pinpoint the exact cause.  

WHINING
Ghouls excised from their mortal forms are known to whine throughout the month of October. But if you notice whining at other times of the year, a transmission issue could be the cause. A failing transmission pump, for example, whines in all gears and is directly proportionate to vehicle speed. As this is just one of several potential causes of a persistent whine, visit your GMC Certified Service dealer for a specific diagnosis. 

HUMMING, GROWLING, OR ROARING
Passenger ghosts streaming their favorite chant. Invisible ethereal beasts sweeping high above a passing storm. Noises such as humming or roaring could indicate a wheel bearing issue. If you. Notice any of these sounds in combination with steering wheel shake, or other vibrations, have your vehicle’s wheel bearings inspected by a GMC Certified Service Expert.
