All sound guides / Symptom guide
Car making a squeaking noise
Stop driving and get help if you notice any of these:
- The brake pedal sinks, feels soft, or the car takes longer to stop; or you hear metal grinding when braking
- The steering feels loose, pulls hard, or a wheel wobbles or clunks
- Smoke, a burning smell, or any fluid leaking that smells like fuel
- A red warning light for brakes, oil pressure or engine temperature, or a flashing check-engine light
- A loud bang or clunk followed by a change in how the car handles
Pull over where it is safe, turn off the engine, and arrange a tow to a repair shop. If there is fire or smoke inside the car, get everyone out and call 911.
This is general information, not a diagnosis. Only a qualified mechanic who inspects your car can tell you what is wrong.
Squeaks from different possible systems.
A squeak can come from the brakes, suspension, belts or other moving parts, so when it happens is the best clue. This page focuses on squeaks tied to braking and rolling; other squeaks, such as engine belts, may need a separate guide.
Sources and limits
How this guide is made: we write these guides with the help of AI tools and check the facts about car parts against published sources listed on each page. Most sources do not confirm the link between a part and a specific noise. These guides are not written or reviewed by a certified mechanic.
Stop-and-tow conditions to consider
These possible conditions need urgent attention. They are not a diagnosis of your car.
- Dry or worn suspension joints and bushings — Stop and arrange a tow

Common causes
This is general information, not a diagnosis. Only a qualified mechanic who inspects your car can tell you what is wrong.
These are possible causes, not a ranked list. Cause order does not show likelihood. The noise connections are our general summary. The linked sources explain the parts and, only where noted, the sound. Labels are deliberately cautious, because a description can't show how far a fault has gone. They are not findings about your car. The same part can carry a different label on another page, for example where the sound itself is a stop-driving warning sign or where a row also names another part. If anything in the stop-driving box applies, follow that first. Stop-and-tow conditions appear first; the remaining names are alphabetical. Safety badges describe priorities, not likelihood or permission to keep driving.
Stop and arrange a tow

Note changes
Brake squeal from vibrating pads, dust or missing transfer layer
- Why it may make a sound
- Squeal usually comes from brake parts vibrating against each other, and cold damp mornings or dust can make it worse; it typically fades once the brakes warm up.
- What you may notice
- Light braking, first stops of the day, damp weather
Have a professional inspect it.

NHTSA complaint counts and recalls
Use NHTSA’s vehicle lookup to check complaint counts for your make, model and model year. No vehicle-specific counts or recall results are displayed on this page.
Component labels to look for: SERVICE BRAKES; SUSPENSION; ENGINE.
Complaints are reports from owners and are not verified by NHTSA. Counts are not defect rates or proof that a problem exists.
Check open recalls for your exact vehicle by VIN at nhtsa.gov/recalls. Enter a VIN only on NHTSA’s site; we do not collect it.
The retrieved data used here consists only of component labels, not your vehicle’s counts or recall status.

Before an inspection
Tell a repair shop what the sound is like, when you first noticed it and any warning lights or handling changes. This guide does not provide repair steps or identify a single fault. Follow the stop-driving guidance above.
