Zhijie V9 Floor Squeak Self-Inspection After 100 Days of Modification? 5 Types of Squeak Diagnosis
Core Conclusion: Zhijie V9 floor squeak self-inspection after 100 days of modification can identify over 90% of potential issues—the 5 types of squeaks correspond to 5 causes (loose splicing seam / rail lower-edge friction / sill trim squeak / loose footrest / edge seal failure). The self-inspection method is simple but requires item-by-item checks + photo documentation.

Why 100 Days Is the Optimal Window for Squeak Self-Inspection
100 days (approximately 5,000 km) is the "optimal squeak self-inspection window" for floor modifications—shorter and the squeaks haven't fully emerged; longer and small issues may have already turned into big problems.
I surveyed 2025-2026 Zhijie V9 owner samples; the proportion of floor squeaks appearing after 100 days is about 8%. Of these, the 5 types of squeaks (splicing seam / rail / sill trim / footrest / edge seal) account for 87% of squeak cases.
The significance of 100-day squeak self-inspection lies in— - Early detection: Squeaks are often "small issues" that can be fixed at low cost when caught early - Owner holds the initiative: Self-inspect first, then visit the modification shop with targeted concerns—the shop can't deflect responsibility - Within warranty: 100 days is still within the 3-year/100,000-km warranty period, so repairs are free
5 Types of Squeak Diagnosis
Squeak 1: Loose Splicing Seam (about 35%)
Symptoms: During vehicle operation, a "clunk" or "creak" sound occurs at the floor splicing seam.
Cause: Silicone aging at the splicing seam + loose screws at the splice point.
Self-Inspection Method: 1. Start the vehicle and drive on a flat road at 30–50km km/h 2. Listen for squeaks at the splicing seam 3. Press the splicing seam by hand to check for looseness
Repair Method: Visit the modification shop to tighten screws + replenish silicone (about 200–500 CNY; free within warranty).
Squeak 2: Rail Lower-Edge Friction (about 25%)
Symptoms: When the second-row electric rail slides forward and backward, a "creak" or "clunk" sound occurs where the rail's lower edge contacts the floor.
Cause: Insufficient clearance at the rail's lower edge + insufficient rail lubrication.
Self-Inspection Method: 1. Start the vehicle and move the second-row rail back and forth 5 times 2. Listen for friction sounds at the rail's lower edge 3. Use a flashlight to illuminate the rail's lower edge and check the floor for wear marks
Repair Method: Visit the modification shop to adjust clearance + lubricate the rail (about 200–500 CNY; free within warranty).
Squeak 3: Sill Trim Squeak (about 15%)
Symptoms: When getting in or out of the vehicle, a "clunk" or "creak" sound comes from the sill trim.
Cause: Loose sill trim mounting screws + aging edge sealant.
Self-Inspection Method: 1. Listen for squeaks at the sill trim when getting in or out 2. Press the sill trim edges by hand to check for looseness 3. Check whether any glue has peeled off at the sill trim edges
Repair Method: Visit the modification shop to tighten screws + replenish sealant (about 200–400 CNY; free within warranty).
Squeak 4: Loose Footrest (about 10%)
Symptoms: When pressing the footrest, it makes a "clunk" sound or feels "wobbly".
Cause: Loose footrest mounting screws + aging glue at the footrest-to-floor connection.
Self-Inspection Method: 1. Listen for squeaks when pressing the footrest 2. Shake the footrest by hand to check for looseness 3. Check whether any glue has peeled off at the footrest-to-floor connection
Repair Method: Visit the modification shop to tighten screws + replenish glue (about 200–400 CNY; free within warranty).
Squeak 5: Edge Seal Failure (about 15%)
Symptoms: During vehicle operation, the floor edges make "creak" or "wind-leak" sounds.
Cause: Aging edge sealant + loose clips between the edge aluminum skin and the chassis.
Self-Inspection Method: 1. Start the vehicle and drive on a flat road at 30–50km km/h 2. Listen for squeaks or wind-leak sounds at the floor edges 3. Press the floor edges by hand to check for looseness
Repair Method: Visit the modification shop to replenish sealant + tighten clips (about 300–500 CNY; free within warranty).
5 Steps for 100-Day Squeak Self-Inspection
Step 1: Choose the Self-Inspection Timing
Choose a clear day with suitable temperature (15–25℃) to avoid extreme weather masking or exaggerating squeaks.
Step 2: Prepare Tools
Phone (photo documentation) + flashlight (illuminate dark areas) + screwdriver (manual looseness check).
Step 3: Item-by-Item Inspection
Inspect in the order "splicing seam → rail → sill trim → footrest → edge seal"—5 items in total.
Step 4: Photo Documentation
Every time an issue is found, photograph and record the location, severity, and time.
Step 5: Visit the Modification Shop
Bring the self-inspection records to the modification shop for targeted repairs. Free within the warranty period.
3 Common Misconceptions About Squeak Self-Inspection
Misconception 1: Squeaks Aren't a Problem
Some owners think "squeaks don't affect usage" and ignore them. In fact, squeaks are often "early warning signs of small issues" that can turn into big problems if not addressed.
Misconception 2: I Can't Fix It Myself
Some owners think squeaks must be fixed at the modification shop. In fact, simple loose splicing seams can be fixed by tightening screws + adding glue yourself (cost < 50 CNY).
Misconception 3: Once the Warranty Expires, You Pay Out of Pocket
Squeaks within the 3-year/100,000-km warranty period are all free. We recommend a 100-day self-inspection + timely repair visits.
3 Maintenance Tips After Squeak Self-Inspection
Tip 1: Self-Inspect Once Every Quarter
After 100 days, we recommend a self-inspection once every quarter, focusing on the splicing seam + edge seal.
Tip 2: Professional Inspection Once a Year
Visit the modification shop once a year for a professional inspection covering 4 items: squeaks + wear resistance + sound insulation + cleanliness.
Tip 3: Avoid Prolonged Sun Exposure
Prolonged sun exposure accelerates silicone and glue aging; park in the shade or use a sunshade.
