Squeaky Brakes and Front End Clunking on 2021 Palisade Calligraphy

ClearTheCode admin answer:

It's concerning to hear about these noises on a relatively new 2021 Hyundai Palisade with only 30,000 miles. While some brake noise can be normal, and minor suspension sounds can occur, your description suggests something might be out of the ordinary. Let's break down the potential causes and next steps:

Brake Squeal:

1. Pad Material: Some brake pad compounds are inherently more prone to squealing, especially when cold or at low speeds. OEM pads can sometimes be noisy.
2. Rotor Glazing/Rust: If the rotors have developed a thin layer of rust (common after rain or washing) or have become 'glazed' from light braking, this can cause squealing.
3. Wear Indicators: Most brake pads have metal wear indicators that start to squeal when the pads are getting low. However, 30,000 miles might be a bit early for significant wear on a Palisade, depending on driving habits.
4. Caliper Issues: A caliper that isn't fully releasing or has sticking guide pins can cause constant light contact and squealing.
5. Lack of Lubrication: The back of the brake pads and caliper contact points should be lubricated with high-temperature grease during installation to prevent vibration and noise. If this wasn't done, squealing can occur.

Front End Clunking:

1. Sway Bar Links/Bushings: These are very common culprits for clunking noises over bumps. The links or their rubber bushings can wear out, creating play.
2. Control Arm Bushings: Worn control arm bushings can also cause clunking, especially during turns or when hitting bumps.
3. Ball Joints: Although less common at 30,000 miles, worn ball joints can create a clunking or popping sound.
4. Strut Mounts/Bearings: Issues with the upper strut mounts or bearings can lead to noise from the front suspension.

When to See a Shop: Given that your Palisade is a 2021 model with only 30,000 miles, it is almost certainly still under the original 5-year/60,000-mile bumper-to-bumper warranty. This means any manufacturing defects or premature wear of components like suspension parts should be covered.

It is highly recommended to take it to a Hyundai dealership for diagnosis. They can properly inspect the brake system and the entire front suspension. Explain both issues clearly. Do not attempt repairs at a local shop that might void your warranty or complicate a potential warranty claim. Addressing these issues promptly is important for both safety and maintaining your vehicle's condition.
