What Causes the Abnormal Noise When the Camry Starts?
3 Answers
There are two reasons for the clicking sound when starting. First, the noise may come from a single brake system, and if not addressed promptly, it could affect all brakes. The second reason is that after washing the car or driving through water, moisture was not dried in time, causing the brake caliper piston or shoe block to fail to return to its original position. Here are the reasons for abnormal noise during startup: 1. Brake System: In southern regions, due to the humid and rainy climate in spring and autumn, long-term driving in such conditions can gradually cause the brake discs to rust. Especially for vehicles whose chassis has been soaked in water, the brake discs are more prone to oxidation and rust. At this time, simply ask a mechanic to sand off the rust on the brake discs during maintenance, and the abnormal noise will disappear. 2. During Startup: The noise may be caused by foreign objects stuck in the tread of the wheels, such as screws, stones, or other hard objects. Removing these foreign objects will solve the noise issue. However, if it's a screw, pay attention to whether the tire pressure has recently dropped, as sharp screws may puncture the tire, causing air leakage. 3. Chassis Issues: This is one of the most common faults. Many cars experience suspension aging after a certain period of use. At this point, some supporting components in the suspension gradually fail, causing abnormal noise from the chassis during startup. It is advisable to visit a 4S shop or professional repair shop promptly for chassis maintenance and inspection to check for loose, aged, or leaking bearings and replace the corresponding parts as needed.
I've been driving a Camry for over a decade, and the strange noise during startup is quite annoying. Common causes include loose components in the suspension system—for instance, a loose stabilizer bar connection can produce a creaking sound when starting. It could also be due to worn brake discs or brake pads causing friction noise, especially noticeable during cold starts. Issues in the drivetrain shouldn’t be overlooked either; worn half-shafts or CV joints can create a clicking sound during acceleration. Aging engine mounts may also lead to vibration noises. To pinpoint the exact cause, try starting on flat ground and listen for the source of the noise, such as whether it’s coming from the front wheels or the chassis. If the noise persists, it’s best to visit a repair shop for a lift inspection—don’t delay to prevent minor issues from escalating.
My Camry had a metallic friction sound when starting last year, which really worried me. Later, I found out it was due to the aging rubber bushings on the front suspension struts, causing a squeaking noise when accelerating. Another friend had the same issue because the brake calipers were loose, leading to abnormal friction between the brake pads and rotors. Problems with the universal joints on the driveshaft are also quite common and can produce a clunking sound. I suggest you first try lightly pressing the brake when starting—if the noise reduces, it might be brake-related. Alternatively, drive at low speeds to listen for changes. It’s best to get a professional inspection of the suspension and drivetrain components early on. Replacing a small part can solve the issue at a low cost and save a lot of hassle. Regular maintenance is key—make sure to periodically check the tightness of the chassis bolts.
