Recently, Qichemen.com unveiled the TOP 10 list of model complaint indices for June 2026, revealing that 80% of the models listed experienced a month-on-month increase in their complaint indices. Among these, the Tang L witnessed the most substantial surge. Although the Excelle GT also saw its complaint index rise month-on-month, the increase was significantly lower compared to the Tang L and other models. Nevertheless, its overall complaint volume remained high, securing its place at the pinnacle of the list. Within the SAIC-GM lineup, the Excelle GT, Malibu XL, and Regal once again featured collectively. BYD's Tang L, Han, and Fangchengbao Titan 7, all new energy models, also made the list, tying with SAIC-GM as the automaker group with the highest number of listed models. German luxury brands were not exempt, with the Audi A4L newly entering the list and joining the Audi Q3 in the top ten. Next, let's delve into the specifics of the TOP 10 model complaints for June 2026.

1st Place: Excelle GT - Complaint Index 305.1

Typical Faults: Steering stiction and abnormal noises, engine fault light illumination

Automobile Quality Complaint Review:

In June, the Buick Excelle GT claimed the top spot with a complaint index of 305.1, marking its fourth consecutive month in the TOP 10 of model complaint indices. Persistent issues such as steering stiction and abnormal noises, along with engine fault light illumination, remained the primary concerns for owners. These problems were predominantly reported in older models from 2016-2019, with some instances also occurring in the 2021 model year. In fact, SAIC-GM Buick had previously initiated a recall for models with steering issues, but due to the age of the affected vehicles, most were no longer under warranty, resulting in limited effectiveness in addressing the problems and a high recurrence rate. Owners generally felt that the manufacturer's approach was merely treating the symptoms rather than the root cause, and the issues had not been genuinely resolved.

2nd Place: Tang L - Complaint Index 272.1

Typical Faults: Discriminatory three-electric system warranty policies, failure of four-wheel drive system to decouple

Automobile Quality Complaint Review:

In June, the Tang L's complaint index skyrocketed 14-fold month-on-month, propelling it to second place on the list. Discriminatory treatment in the three-electric system warranty and the failure of the four-wheel drive system to decouple emerged as the two core issues sparking owner dissatisfaction. Multiple owners reported that the annual mileage limit for the lifetime warranty of the Tang L's three-electric system was 30,000 kilometers, while the "Da Tang" model, of the same series and positioning, had a limit of 50,000 kilometers, leading to accusations of unequal treatment. Additionally, the inability to automatically switch back to two-wheel drive after engaging four-wheel drive resulted in abnormally high energy consumption, contradicting the official promotion of an "imperceptible decoupling" feature for the intelligent four-wheel drive system, drawing criticism from many owners. Notably, these issues were exclusive to the 2025 Tang L, a model discontinued less than a year after its launch, leaving owners feeling "betrayed." Currently, owners are demanding that the manufacturer standardize the warranty mileage limits and promptly address the four-wheel drive decoupling issue through OTA updates. However, despite the concentrated complaints from owners, the official has yet to provide a substantive response.

3rd Place: Malibu XL - Complaint Index 223.65

Typical Faults: Transmission unable to engage P gear, roof paint cracking, high-mounted brake light cracking

Automobile Quality Complaint Review:

In June, the Malibu XL saw a slight 16.85% month-on-month increase in its complaint index. Although the increase was not significant, "chronic issues" such as the transmission's inability to engage P gear, roof paint cracking, and high-mounted brake light cracking resurfaced in a concentrated manner, maintaining high complaint levels. The transmission fault stemmed from a design flaw in the P gear microswitch, affecting models from the 2017 to 2022 model years. The high-mounted brake light cracking issue spanned models from the 2019 to 2023 model years, while paint issues were predominantly found in the 2021 and 2022 model years. These "old problems" were not unique to the Malibu XL; similar complaints frequently arose for same-brand models like the Buick Excelle GT and Regal, indicating a systemic issue across multiple SAIC-GM models. However, to the dissatisfaction of owners, SAIC-GM Buick responded with an indifferent attitude, merely stating that the vehicles were "out of warranty and required self-payment" for repairs. Some owners reported that the faults recurred after repair, eroding their patience. The combination of persistent old problems and the manufacturer's lack of responsibility has made the path to rights protection particularly arduous for long-time owners.

4th Place: Accord - Complaint Index 208.05

Typical Faults: Fuel injector faults, air conditioning refrigerant leakage, door rusting

Automobile Quality Complaint Review:

This month, the Accord's complaint index rose by 90%, returning to the top ten complaint list after just one month. Owner complaints continued to focus on the three "usual suspects": fuel injector clogging, air conditioning refrigerant leakage, and door rusting. Fuel injector clogging had become a "signature issue" for the Accord's 1.5T engine. Multiple owners reported that after driving 40,000 to 80,000 kilometers, the engine fault light illuminated, accompanied by shaking and misfiring. 4S dealerships quoted approximately 4,000 yuan for a set of fuel injector replacements. Even with regular maintenance, owners still encountered these issues, yet Honda often refused free repairs on the grounds that the vehicles were "out of warranty." With summer approaching, the issue of air conditioning refrigerant leakage resurfaced. Owners reported that the leakage was caused by a defect in the condenser material, rather than normal wear and tear. Recharging the refrigerant only provided temporary relief, with the problem recurring shortly after. The issue of door rusting was primarily found in the 2016 and 2018 model years, with even some 2025 models exhibiting rusting and blistering less than seven months after purchase. After owners filed complaints, the manufacturer either shirked responsibility by citing the warranty expiration or blamed "rain and car washing," consistently adopting a cold and unresponsive approach.

5th Place: Audi A4L - Complaint Index 180

Typical Faults: Tire cracking, sunroof leakage

Automobile Quality Complaint Review: The Audi A4L, which had fallen out of the top ten complaint list for several months, made a comeback this month. In June, the Audi A4L's complaint index reached 180, marking a 90.48% month-on-month increase. This time, owners concentrated their complaints on two main issues: tire cracking and sunroof leakage. Numerous owners reported that after driving approximately 20,000 kilometers, cracks appeared across the shoulders of all four tires. The problematic tires involved multiple brands, including Pirelli and Michelin, leading owners to generally believe that the issue stemmed from defects in the rubber compound or material itself, rather than improper use. However, 4S dealerships often refused compensation by citing "external damage," with tire manufacturers and dealerships passing the buck to each other, leaving owners with no recourse for rights protection. Complaints about sunroof leakage were also concentrated. Aging and cracking of the drainage pipes, along with bracket fractures, led to water accumulation inside the vehicle, soaking the roof lining. What frustrated owners even more was that even after repairs, the leakage problem persisted. Some owners bluntly stated that "when it rains heavily outside, it drizzles inside the car." These issues affected multiple model years of the Audi A4L, from 2017 to 2023, and were not isolated to specific models. Owners believed these were batch-related quality issues, and the manufacturer should bear the responsibility for free repairs rather than shifting the blame to dealers. However, Audi had yet to provide a clear explanation. (Image sourced from the internet, removal upon infringement)
