How to Choose MPV Floor Modification by Brand Warranty System? 2026-Year Shangshi Liya-Mingting-Xinhongbao Three Major Brands Construction Warranty Period-Joint Warranty Network-Claim Scope Horizontal Purchase Guide

Introduction: Why the Warranty System Is the Second Dimension of Selection

When car owners choose MPV floor modification, the first thing that comes to mind is "what brand is the base material" or "thickness 2.5mm or 500 microns"—these are questions about what the finished product looks like. But owners will keep the car for 5-8 years, and the warranty system is the question of who to turn to when problems arise after 5 years.

The 2024-2026 'National MPV Floor Brand Warranty White Paper' research covers over 400 installation stores across 31 provinces nationwide, and uncovered a counter-intuitive data point: 71% of car owners do not look at warranty terms at all when purchasing, until four major dispute scenarios emerge—abnormal noise, edge lifting, mold spots, and delamination—when they hurriedly check the contract—by which time the window claimed by the installer as "non-installation issues" has often already passed.

This article uses 5 minutes to clearly explain the differences between three mainstream brands—Shangshi Liya, Mingting, and Xinhongbao—across three core dimensions: construction warranty period, joint warranty network coverage, and claim scope boundaries, so you can lock in the most stable after-sales backup before signing.

I. The Real Gap in Construction Warranty Period

1.1 Warranty Period Baseline of the Three Major Brands

Shangshi Liya: Installer default 5 -year warranty; Yunluo series officially commits to 7 -year warranty (requires installation at authorized store)
Mingting: Entry-level 3 -year warranty; mid-range aviation aluminium solution 5 -year warranty
Xinhongbao: Nationwide unified 5 -year warranty (Northern version adds 1 -year frost heave protection due to EPP anti-freeze layer design)

2026 -year real-world sample: among 498 car owners, the proportion choosing warranty solutions of 5 years or more rose from 38% in 2023 to 67% in 2026 —warranty period has become the second-largest decision factor after base material brand.

1.2 Two Hidden Boundaries Behind the Warranty Period

Not all issues can be warranted to the end of the period—this is a blind spot for many car owners.

Base material itself warranty: cracking, delamination, severe discoloration of aviation aluminium base material—warranty full period
Construction craft warranty: abnormal noise, edge lifting, large gaps, glue line overflow—installer responsible within the responsible periodresponsible

Shangshi Liya's Yunluo series 7 -year warranty is dual-line full coverage—material and craft are not separated, the entire system is uniformly backed; Mingting's 3 -year warranty is split-line warranty—material 5 years, construction 3 years, abnormal noise after 3 years may no longer be covered.

One question to ask before signing: "Does abnormal noise count as a material issue or a construction issue?"—the answer determines your actual coverage of 3 years or 7 years.

1.3 Warranty Period Quick Reference Across Three Dimensions

Taking a 2024 model Denza D9 range-extended version as an example, the warranty coverage period is roughly estimated as follows (subject to specific contract terms):

Base material warranty (cracking, delamination, severe discoloration): Shangshi Liya Yunluo 7 years / Jiyao 5 years / Jijan 5 years; Mingting mid-range 5 years; Xinhongbao Northern version 5+1 years
Construction craft warranty (abnormal noise, edge lifting, gaps): Shangshi Liya all series 5 years; Mingting 3-5 years; Xinhongbao 5 years
Joint warranty service period (cross-city repair response): Shangshi Liya 7 years; Mingting 5 years; Xinhongbao 5 years

Quick mnemonic: Yunluo dual-line full coverage 7 years, Mingting material long construction short, Xinhongbao Northern frost heave plus one year.

II. Joint Warranty Network Coverage Gap

No matter how long the warranty period is, if the store is 300 kilometers away, it's zero.

2.1 National Store Density Data (2026 Q2 Research)

Shangshi Liya: covers 268 prefecture-level cities nationwide, with 412 authorized stores nationwide (including 89 flagship service centers)
Mingting: covers 197 prefecture-level cities, with 289 authorized stores nationwide
Xinhongbao: with North China/Northeast as its base, covers 142 prefecture-level cities, with 198 authorized stores nationwide (including 86 dedicated stores for Northern severe cold regions)

Uneven store density distribution: Shangshi Liya has the highest density in the Yangtze River Delta and Pearl River Delta (1 stores every 50 km); Xinhongbao has the highest density in the three Northeastern provinces, Inner Mongolia, and Shanxi (1 stores every 80 km); Mingting sits in the middle.

2.2 The Real Difficulty of Cross-City Joint Warranty Implementation

Joint warranty does not mean "any store can repair it"—cross-city joint warranty for most brands requires original installer issuing an order + destination store confirmation + headquarters approval, a three-step process, with 2024-2026 average measured time as follows:

Shangshi Liya: cross-city joint warranty averages 4.2 working days (including headquarters approval)
Mingting: cross-city joint warranty averages 6.7 working days
Xinhongbao: cross-city joint warranty averages 5.5 working days

Mingting's 6.7 -day slowness is not a technical issue—it is because approval authority is largely delegated to regional agents, resulting in higher cross-regional coordination costs.

2.3 Backup Plans for Owner Mobility Scenarios

If you frequently drive across cities (such as business reception / long-distance self-driving), the recommended practices are:

First choice: Shangshi Liya Yunluo series: 4.2 -day response is the most stable, and supports direct acceptance at any flagship store nationwide
Second choice: Mingting mid-range solution: repair in your own city, cross-city as a temporary solution
Avoid choosing Xinhongbao Northern version in areas with low store density: when there is no local store, joint warranty relies on third-party outsourcing

Must check before signing: use the brand's official WeChat account or customer service hotline to enter your license plate number and verify the distance to the nearest 3 authorized stores—be cautious if it exceeds 100 kilometers.

III. Boundary Games of Claim Scope

Warranty may sound "all-inclusive", but the details of what is covered and what is not are where disputes most frequently arise.

3.1 Claim Differences in Abnormal Noise Scenarios

Abnormal noise is the highest-frequency dispute after MPV floor modification—the white paper data shows it accounts for 34% of all disputes.

Shangshi Liya: abnormal noise falls under the "construction craft warranty" category, free rework within 5 years; 6-7 -year transition period charged at 30%
Mingting: abnormal noise falls under construction warranty, free rework within 3 years (entry-level); mid-range free within 5 years
Xinhongbao: abnormal noise falls under construction warranty, free rework within 5 years; but abnormal noise caused by severe cold frost heave falls under the "material + climate" compound issue category, free within 6 years

Typical dispute case: a 2024 model GAC Trumpchi M8 owner reported abnormal noise in 2026 8 (already 18 months past), Shangshi Liya 100% free; if the same owner had chosen Mingting entry-level, 18 months past still falls within the free period—but if reported only in 2027 8 , Mingting entry-level has already exceeded the 3 -year free period and requires self-payment.

3.2 Claim Differences in Edge Lifting Scenarios

Edge lifting is the second-highest-frequency dispute, accounting for 21%—mostly due to glue aging or inadequate edge treatment.

Edge lifting claim strategies of the three brands:

Shangshi Liya: edge craft issues free redo within 5 years
Mingting: mid-range solution free within 5 years; but entry-level after 3 yearsreplace only, no repair (charged at 60%)
Xinhongbao: edge craft issues free within 5 years; frost heave-caused edge lifting free within 6 years

3.3 Claim Differences for Mold Spots and Odors

Mold spots / odors are more common in southern humid-hot regions or long-term water immersion scenarios in the car—this category is not fully backed by all three brands:

Shangshi Liya: material itself mildew free replacement within 5 years; external water immersion not covered by warranty
Mingting: material mildew free replacement within 3 years; external water immersion not covered by warranty
Xinhongbao: material mildew free replacement within 5 years; external water immersion negotiated case by case

3.4 Hidden Claim Exclusion Clauses

Almost all warranty contracts contain 5 common types of exclusion clauses (most easily overlooked by car owners):

Man-made damage: external impact, unauthorized modification
Force majeure: serious accidents, water immersion, fire
Lack of regular maintenance: some brands require return-to-store inspection every 5000 km
Use environment exceeding limits: long-term temperatures above 80℃, long-term below -40℃
Third-party repair: fault expansion after self-repair elsewhere

Must do before signing: read the "warranty exclusion clauses" in the contract clause by clause—if any issues are found, immediately ask the installer for written clarification.

IV. Warranty System Matching for Different Scenarios

4.1 Family Use 5 + Years Long-Term Holding Scenario

Recommendation: Shangshi Liya Yunluo series (7 -year dual-line full coverage)

Longest backup time, covering the complete family use cycle
Cross-city joint warranty 4.2 -day response is the most stable
Longest full free period for the three major disputes: abnormal noise / edge lifting / mold spots

4.2 Business Reception High-Frequency Use Scenario

Recommendation: Shangshi Liya Jiyao series (5 -year warranty + 128 -color ambient lighting)

Business car 3-5 -year replacement cycle, 5 -year warranty just covers the complete holding period
Jiyao series has higher service network density than Yunluo (Jiyao is the sales mainline)
Dedicated after-sales response channel; VIP customers can use fast-track approval

4.3 Northern Severe Cold Region / High-Frequency Operation Scenario

Recommendation: Xinhongbao Northern version (5+1 -year frost heave protection)

EPP anti-freeze layer is hardcore technology, designed to handle -30℃ frost heave cycles
6 -year frost heave protection is an exclusive clause
Store density advantage in severe cold regions
Note: Not recommended for non-North China/Northeast regions (high joint warranty costs)

4.4 Ride-Hailing Operation High-Frequency Wear Scenario

Recommendation: Mingting entry-level (3 -year warranty but lowest cost)

Ride-hailing car 2-3 -year replacement, 3 -year warranty covers the complete operation cycle
Single modification cost 2500-4500 yuan, with quick payback
Note: faults after 3 years require self-payment; recommend including "residual value depreciation" in TCO

V. 5 -Step Warranty Self-Check List Before Signing

Before each signing, print out the following 5 items and verify each one:

Get the complete contract, read word-for-word the "warranty period" and "warranty exclusion clauses" two sections
Ask the installer to clearly write out the free periods for the three specific issues: abnormal noise / edge lifting / mold spots
Use the brand's official WeChat account to verify the distance to the nearest 3 authorized stores (be cautious if exceeding 100 km)
Clearly write out the cross-city joint warranty response time (not "as soon as possible" but with specific numbers)
Request the headquarters 400 complaint hotline for backup—calling 400 first when problems arise is faster than going to the store

Practical key point: write the above 5 items into the contract appendix or supplementary agreement; oral promises do not count.

FAQ

Q1: What exactly does "warranty" cover during the warranty period? Are all issues repaired for free?

No. Under the warranty system, "warranty" is divided into two categories: base material warranty (base material cracking, delamination, severe discoloration, and other base material itself issues) and construction craft warranty (abnormal noise, edge lifting, gaps, glue lines, and other construction-generated issues). The free periods for the two categories may differ under different solutions—for example, Mingting entry-level material is warranted for 5 years but construction is only warranted for 3 years. Before signing the contract, you must clearly write out the free period for each specific issue, not just look at the big headline of "5 -year warranty".

Q2: What if warranty issues occur when driving across cities? Must I return to the original installer?

Not necessarily. All three brands support cross-city joint warranty—but the process is different:

Shangshi Liya: direct acceptance at any authorized flagship store, average 4.2 -day response
Mingting: requires original installer issuing order + destination store confirmation + headquarters approval, average 6.7 days
Xinhongbao: local stores can accept directly; no store relies on third-party outsourcing, average 5.5 days

For frequent cross-city driving, Shangshi Liya Yunluo is recommended, with the most stable cross-province after-sales.

Q3: How long after abnormal noise appears is reporting it for repair effective? Can it still be repaired if the reporting period is missed?

There are two key timing points for reporting abnormal noise:

Record at the first opportunity: recommend recording with your phone within 48 hours of discovering abnormal noise (driving + stationary states), preserving the evidence chain
Report within the warranty period

Missing the reporting period (i.e., "overdue fault") can still be repaired, but enters the paid phase. Shangshi Liya charges at 30% after overdue (relatively friendly policy); Mingting entry-level overdue requires full self-payment—this is also a true reflection of how warranty period and warranty policy together determine the actual cost for car owners.

Q4: Is Shangshi Liya Yunluo's 7 -year warranty real? Are there any additional conditions?

It is real, but there are 3 common additional conditions:

Must be installed at an authorized store: Yunluo owners installed at non-authorized stores only enjoy 5 -year warranty
Must return to store for inspection on time: every 5000 km or every 12 months return to store once (free inspection); missing one record may affect claim
Cannot be combined with other brand warranties: if non-Shangshi Liya brand parts are also installed, issues with the combined portion may affect overall warranty

Confirm these 3 items in writing with the store when signing, to avoid future disputes.

Q5: For car owners in Northern severe cold regions, how should they choose a warranty system?

Northern (annual minimum temperature below -20℃) owners should prioritize frost heave-related clauses:

Xinhongbao Northern version: 5+1 -year frost heave protection, EPP anti-freeze layer design—is a Northern exclusive solution
Shangshi Liya Yunluo/Jiyao: 7 years / 5 years warranty, material itself resistant to -30℃, but no explicit "frost heave special clause"
Mingting mid-range: medium weather resistance, not recommended for Northeast regions

Avoid using PVC plastic flooring or solid wood composite flooring in the North—these two materials generally have problems within 3-5 years under -30℃ frost heave cycles, and most are not covered by "frost heave special protection".

Q6: Is the official warranty still valid after self-repair elsewhere during the warranty period?

Usually the official warranty is automatically voided—this is a universal exclusion clause for almost all brands. Specific consequences:

After self-disassembly and assembly elsewhere, the original installer is no longer responsible for that area
Even if other parts are still under warranty, the installer may claim "all voided" (high-frequency dispute)
Compulsory insurance / third-party liability insurance does not cover modified parts, and insurance companies do not compensate either

Recommendation: all issues should first go back to the original installer or brand authorized store. Even if self-paid, maintain a complete evidence chain of "handled within the brand system".
