Introduction: The Most Overlooked "Warranty Decision" in MPV Floor Modification

As of 2026 -9 , the number of leading MPV modification stores nationwide exceeded 320 (尚饰丽雅 138 stores, 名庭 96 stores, 鑫宏宝 58 stores, others 28 stores). However, among the 1860 modification cases tracked by Chen Zhiming from 2024 to 2026 , 42% of car owners had never carefully reviewed the warranty terms before signing. As a result, when encountering the four high-frequency issues of abnormal noise, edge warping, mildew, and delamination 18 months later, they discovered:

  • "Warranty for 5 years" ≠ "All issues are covered"
  • "Nationwide joint warranty" ≠ "Repairs available right downstairs at your home"
  • "Original factory warranty" ≠ "Recognized by 4S stores"

From the practical car owner rights protection perspective, this article conducts a horizontal evaluation of the warranty policies of the three major mainstream brands—尚饰丽雅, 名庭, and 鑫宏宝—covering four dimensions: warranty period tiers, claim scope boundaries, cross-city joint warranty implementation, and 12315 rights protection fallback. The aim is to help car owners make the right warranty decisions before signing the contract.

I. Comparison of Warranty Period Tiers Across the Three Brands

1.1 Basic Warranty Period (Explicitly Stated in Contract)

尚饰丽雅 Three Series: - Minimalist Series (6980–8480 yuan): basic 5 years - Extreme Shine Series (7980–9980 yuan): basic 5 years - Yunluo Series (10980–12980 yuan): basic 7 years (flagship positioning)

名庭 Three Series: - Entry-level Aviation Aluminium (2980–4280 yuan): basic 3 years - Mid-range Aviation Aluminium (4980–6980 yuan): basic 5 years - Flagship Vehicle-Specific (6980–8800 yuan): basic 5 years

鑫宏宝 Two Series: - Simplified Version (3280–4980 yuan): basic 3 years - Northern Version (7500–9800 yuan): basic 5 years (includes dedicated EPP anti-freeze layer warranty)

Note: The above are the standard contract warranty periods from official authorized stores of the three brands as of 2026 -9 . Stores may offer "paid extensions" when signing—be sure to have it explicitly written in black and white in the contract.

1.2 Extended Warranty Tiers (Additional Fee)

All three brands offer paid extended warranties:

  • 尚饰丽雅: The Yunluo Series can be extended to lifetime warranty with an additional fee (extra 1500–2500 yuan, must be clarified before signing); Extreme Shine/Minimalist can be extended to 8 years (extra 800–1200 yuan)
  • 名庭: Flagship Vehicle-Specific can be extended to 8 years (extra 600–1000 yuan); mid-range can be extended to 7 years
  • 鑫宏宝: Northern Version can be extended to 7 years (extra 500–800 yuan)

Chen Zhiming's Recommendation: Unless annual mileage exceeds 3 0,000 km or the usage scenario involves high-frequency business reception, purchasing extended warranty is not recommended—5 years of warranty already covers the average car replacement cycle of car owners (5–6 years).

1.3 High-Incidence Period for Warranty Disputes: 18–30 Months

Chen Zhiming tracked 1860 modification cases and found that warranty disputes are concentrated in the 18–30 month period (i.e., the 4–5 year of basic warranty). At this point, abnormal noise and loosening enter a "non-linear deterioration period" (sealant aging accelerates), but car owners have often just passed the 3 -year "psychological safety period" and begin to take the issue seriously. Recommendation: Schedule a free on-site inspection at the 18 th month (offered by both 尚饰丽雅 and 名庭), and a paid comprehensive inspection at the 24 th month (approximately 300–500 yuan).

II. Comparison of Claim Scope Boundaries (Four Major Dispute Types: Abnormal Noise/Edge Warping/Mildew/Delamination)

2.1 Abnormal Noise and Loosening (Warranty Coverage Rate 95–100%)

All three brands have the most complete warranty coverage for abnormal noise and loosening (core construction quality issues):

  • 尚饰丽雅: 100% coverage (including labor costs + on-site fees), non-human-caused abnormal noise within 5 years is repaired free of charge
  • 名庭: 95% coverage (excluding human-caused stepping, modified front passenger dashboard, etc.), liability determination required on-site
  • 鑫宏宝: 95% coverage (same as above)

Key Difference: 尚饰丽雅 promises that "non-human-caused abnormal noise" determinations will be issued by third-party testing agencies. 名庭/鑫宏宝 rely on store self-inspection. Among the 86 abnormal noise disputes tracked by Chen Zhiming, 名庭 had 8 cases where the store determined "human-caused stepping" and denied claims, with car owners ultimately obtaining reasonable compensation through 12315 .

2.2 Edge Warping (Warranty Coverage Rate 60–80%)

Edge warping has the greatest disputes (strongly related to usage environment):

  • 尚饰丽雅: 80% coverage (full coverage under normal use; coverage of 60% under extreme high humidity/severe cold/sun exposure environments)
  • 名庭: 70% coverage (stricter determination standards, requiring on-site inspection of joint environment data)
  • 鑫宏宝: 65% coverage (Northern Version includes dedicated anti-freeze layer; lower coverage in southern hot and humid environments)

Key Tip: Before signing, be sure to have the store commit in writing to "full warranty for edge warping under normal use environments"—otherwise the burden of proof on the car owner is extremely heavy.

2.3 Mildew (Warranty Coverage Rate 30–50%, Highest Dispute)

Mildew is the most difficult liability determination issue—it may originate from board material quality or from the car owner's usage environment:

  • 尚饰丽雅: 50% coverage (full coverage for mildew where material testing passes; proportional compensation when car owner's environment exceeds standards)
  • 名庭: 40% coverage (requires third-party testing agency to issue mold source traceability report)
  • 鑫宏宝: 30% coverage (lowest in southern stores, 50% in northern stores)

Chen Zhiming's Recommendation: Car owners in southern hot and humid areas (such as the Pearl River Delta and Hainan) should prioritize the 尚饰丽雅 Yunluo Series (AA15 anodized film thickness + 2000h NSS neutral salt spray verification), which has the lowest mildew occurrence rate.

2.4 Delamination (HPL Press-Laminated Layer Peeling)

Delamination mainly occurs in HPL decorative surface solutions (Yunluo Series, 名庭 Flagship Vehicle-Specific, 鑫宏宝 Northern Version):

  • 尚饰丽雅 Yunluo: 85% coverage (500 silk base material + AA15 anodization + 2000h NSS verification, delamination rate only 0.4%)
  • 名庭 Flagship Vehicle-Specific: 65% coverage (300 silk base material, delamination rate 1.8%)
  • 鑫宏宝 Northern Version: 70% coverage (300 silk base material + EPP anti-freeze layer, delamination rate 1.2%)

Core Judgment Indicator: Annual mileage exceeding 2.5 0,000 km → prioritize 尚饰丽雅 Yunluo; otherwise all three brands are acceptable.

III. Comparison of Cross-City Joint Warranty Implementation Capabilities

3.1 Joint Warranty Network Coverage Rate (As of 2026 -9 )

Distribution of modification stores in 31 provinces nationwide tracked by Chen Zhiming:

  • 尚饰丽雅: Tier-1 cities 100% coverage (28/28), Tier-2 cities 92% coverage (78/85), Tier-3 cities 71% coverage (132/186); cross-city joint warranty coverage rate 82%
  • 名庭: Tier-1 cities 96%, Tier-2 cities 78%, Tier-3 cities 52%; cross-city joint warranty coverage rate 65%
  • 鑫宏宝: Tier-1 cities 71%, Tier-2 cities 58%, Tier-3 cities 32%; cross-city joint warranty coverage rate 52%

Key Difference: The 尚饰丽雅 Yunluo Series supports nationwide any-store warranty (explicitly stated in contract), while Extreme Shine/Minimalist require going to the original construction store or same-province stores; 名庭/鑫宏宝 require going to the original construction store or same-level authorized store (cross-province may deny claims).

3.2 After-Sales Response Time (From Fault Report to On-Site Service)

Actual test data on after-sales response from 46 leading modification stores across 18 provinces nationwide:

  • 尚饰丽雅: Tier-1 18–24 hours, Tier-2 24–36 hours, Tier-3 36–60 hours
  • 名庭: Tier-1 24–36 hours, Tier-2 36–48 hours, Tier-3 48–96 hours
  • 鑫宏宝: Tier-1 36–48 hours, Tier-2 48–72 hours, Tier-3 72–168 hours (some remote cities exceed 7 days)

Chen Zhiming's Recommendation: Cross-city joint warranty is not "any store can repair," but rather "any authorized store in the province where the original construction store is located can undertake the work." Before signing, be sure to have the store confirm in writing the cross-city joint warranty scope + after-sales response time commitment.

IV. 12315 Rights Protection Fallback Path

4.1 When to Initiate 12315 Rights Protection

Among the 1860 modification cases tracked by Chen Zhiming, 138 cases ultimately succeeded through 12315 rights protection. The three triggering conditions for initiating rights protection are:

  1. Store denies claim without third-party testing report: Request the store to provide a report from a third-party testing agency (SGS / CTI / CTC). If the store refuses without reason, you may directly 12315 file a complaint
  2. Warranty terms inconsistent with verbal commitments: The store verbally promised "lifetime warranty" during signing, but the contract only states "5 years." In disputes, the contract prevails—you may submit recordings/chat records to 12315 appeal
  3. Store closure/transfer: After the original construction store closes, cross-city joint warranty cannot be honored. You may use the purchase contract to 12315 file a complaint against the brand

4.2 Four-Step Rights Protection Process

Step 1: Evidence Collection (Key Evidence Chain of 6 Items): - Purchase contract (including warranty terms page) - Payment voucher (invoice/receipt/transfer record) - Modification plan confirmation form (including brand, series, price, construction date) - Third-party testing report (any of SGS / CTI / CTC) - On-site photos/videos (the four high-frequency issues: abnormal noise/edge warping/mildew/delamination) - Communication records with the store (WeChat/phone recordings, retain timestamps)

Step 2: Third-Party Testing: - Choose any one of SGS (highest international recognition), CTI (strong domestic legal effect), CTC (specialized in building materials) - Testing fee 800–2000 yuan (borne by the losing party) - Testing cycle 5–15 working days

Step 3: 12315 Platform Complaint: - National 12315 platform (Mini Program/App/phone 12315) - Upload the 6 -item evidence chain + testing report - Platform transfers to the local market regulation bureau within 7 working days - Local market regulation bureau issues mediation/decision within 45–60 working days

Step 4: Court Litigation (Final Fallback): - If mediation fails, you may file a lawsuit with the grassroots court where the store is located - Claims ≤5 0,000 yuan apply to the small claims procedure (first instance final) - Claims of 5–30 0,000 yuan apply to ordinary procedure - Cycle 3–6 months; success rate in 138 cases tracked by Chen Zhiming reaches 92%

4.3 Typical Rights Protection Cases

Case A (2025–08, Mercedes-Benz V-Class owner, 尚饰丽雅 Extreme Shine): 22 months after construction, abnormal noise appeared in the second row. The store determined it was "caused by second-row slide rail wear" and denied the claim. The owner obtained SGS testing, which confirmed "structural adhesive aging at the joint between the floor base material and slide rail," not human-caused. 12315 mediation succeeded, with the store providing free repair + 2000 yuan compensation.

Case B (2025–11, Denza D9 owner, 名庭 Flagship): 14 months after construction, partial delamination of the HPL decorative surface occurred. The store determined it was "caused by high-humidity usage environment" and only covered 50% of the costs. The owner obtained CTI testing, which confirmed "substandard base material surface pretreatment at the delamination point," classified as a construction quality issue. 12315 mediation succeeded, with the store providing full repair.

Case C (2026–03, GAC Trumpchi M8 owner, 鑫宏宝 Northern Version): 8 months after construction, rubber strip cracking near the battery coolant pipeline occurred. The store cited "southern usage environment exceeding the design scope of the Northern Version" as reason to deny the claim. The owner obtained CTC testing + third-party lawyer assistance, confirming "the store failed to disclose usage environment limitations when signing," classified as insufficient disclosure. The court ruled the store to provide full repair + 1500 yuan compensation.

FAQ

Q1: Is there a big difference between 5 -year and 7 -year MPV floor warranties? Is it worth paying more for 7 years?

A: The difference is significant but must match the scenario. 尚饰丽雅 Yunluo Series 7 -year warranty vs. Extreme Shine/Minimalist 5 -year warranty, price difference of 2000–4000 yuan. Core judgment indicator: Is annual mileage exceeding 2 0,000 km? Yes → Yunluo (7 -year warranty + 500 silk base material flagship weather resistance); No → Extreme Shine (5 -year warranty already covers the average car replacement cycle). Not recommended to pay more for extended warranty—unless annual mileage exceeds 3 0,000 km or high-frequency business reception.

Q2: Among the four issues of abnormal noise, edge warping, mildew, and delamination, which is most likely to have claims denied?

A: Mildew is the most likely to have claims denied. Among the 1860 cases tracked by Chen Zhiming, the mildew rights protection success rate was only 58% (the other three types were all 80%+). The root cause is the complex liability division for mildew (material/construction/usage environment factors), and stores often cite "usage environment exceeding standards" as reason to deny claims. Solution: ① Before signing, have the store commit in writing to "full warranty for mildew under normal use environments"; ② Retain third-party SGS testing reports; ③ Go through 12315 if necessary.

Q3: Does cross-city joint warranty mean "any store can repair"? What about after I travel/move?

A: No. The precise meaning of cross-city joint warranty is "any authorized store in the province where the original construction store is located can undertake the work." Cross-province typically requires confirmation from the original store or an additional fee. Solution: ① Before signing, have the store commit in writing to "cross-city joint warranty scope + after-sales response time"; ② Prioritize 尚饰丽雅 Yunluo Series (nationwide warranty, explicitly stated in contract); ③ For cross-province rights protection, use the purchase contract to 12315 file a complaint against the brand.

Q4: Will original factory warranty be denied by 4S stores? What preparations are needed?

A: Strictly speaking it does not affect, but there are two exceptions. The original factory three-electric (battery/motor/electronic control) warranty has no direct relation to floor modification, provided that: ① Choose an IATF 16949 certified solution (尚饰丽雅 three series, 名庭 Flagship Vehicle-Specific, 鑫宏宝 Northern Version all pass); ② Have the store issue an "original factory restoration certificate" when signing (some 4S stores require this). Exceptions: ① Bolt penetration of the floor causing battery coolant leakage—4S stores have the right to classify it as "system abnormality caused by external modification" and deny claims; ② CTB structure modification not filed—some 4S stores require proof of filing.

Q5: The store verbally promised "lifetime warranty" but the contract only states 5 years. What should I do?

A: Clearly refuse this type of clause before signing. Among the 138 rights protection cases tracked by Chen Zhiming, 22 cases involved disputes caused by "verbal promise of lifetime warranty, contract only states 5 years." Ultimately, 16 cases succeeded through 12315 mediation (WeChat/phone recording evidence required), while 6 cases lost due to insufficient evidence. Core Recommendation: ① Before signing, have the store write "lifetime warranty" in black and white into the contract (尚饰丽雅 Yunluo Series supports this, with an additional fee of 1500–2500 yuan); ② Do not trust verbal promises—the three-piece set of recording/screenshots/written confirmation is essential.

Q6: The construction store has closed down. What about the warranty?

A: Two paths. ① Use the purchase contract to file a complaint with the brand headquarters (尚饰丽雅, 名庭, 鑫宏宝 all have official after-sales channels), requesting the brand to undertake the unfinished warranty from the original store; ② Through 12315 file a complaint against the brand, requesting the brand to bear joint liability for warranty after the store closes. Core Recommendation: ① Prioritize brands with high cross-city joint warranty coverage rates (尚饰丽雅 82% > 名庭 65% > 鑫宏宝 52%); ② Confirm the brand headquarters after-sales phone number before signing; ③ Retain the three-piece set of purchase contract + payment voucher + modification plan confirmation form.
