China Net Automobile, January 24 On the China Net Automobile Complaint Platform (https://315.auto.china.com.cn/), there are many cases of complaints about Mercedes-Benz's "48-volt on-board power system failure", including Beijing Benz C260 series, 2024 Mercedes-Benz GLB 220 and other models. Not long ago, Ms. Pan, the owner of a 2024 Mercedes-Benz GLB 220, complained about the "48-volt on-board power system failure" of her vehicle on the China.com automobile complaint platform, which was also reported by a reporter from China.com (http://auto.china.com.cn/news/20231204/725727.shtml). After communication and feedback from the platform, Ms. Pan finally applied for the closure of the case on the China.com automobile complaint platform recently, saying that the vehicle complaint problem had been solved and expressing her gratitude to the platform.
Ms. Pan, the owner of the car, previously said that she bought a 2024 Mercedes-Benz GLB 220 model at a 4S store in Tianjin in October this year, but after less than a month of use, there was a warning of "48-volt on-board power system failure" on the vehicle dashboard. It is accompanied by the failure of the vehicle to catch fire, and the failure of the power windows and other buttons.
In fact, the 48V mild hybrid system is not a new technology, theoretically equipped with 48V mild hybrid system has the advantages of reduced emissions, fuel saving, and low cost, but because the actual energy saving and emission reduction effect is not obvious, more and more car companies give up the 48V mild hybrid system and choose HEV gasoline-electric hybrid, PHEV plug-in hybrid, REEV extended range hybrid and other power forms. On the contrary, the "48-volt on-board power system failure" has caused a lot of complaints on the Beijing Mercedes-Benz C260 car series before. If the "48-volt on-board power system failure" of the vehicle cannot be solved after the warranty period, it is necessary to bear the high maintenance costs, which will cause complaints from the owner.
Back to Mercedes-Benz GLB, Beijing Benz officially launched the domestic GLB in the domestic market in April 2020, and only provided GLB 180 and GLB 200 versions equipped with 1.3T four-cylinder engines in the early days of its listing. As a result, Beijing Benz has added a GLB 220 model equipped with a 2.0T engine for the 2022 and 2023 models. It is worth noting that neither the 2022 nor 2023 GLB 220 models have a 48V mild hybrid system in their powertrains, so none of the previous models have suffered from complaints about "48-volt on-board power system failure". However, it is extremely puzzling that Beijing Benz has introduced the 48V mild hybrid system that has been complained about before, for the mid-term facelift 2024 GLB 220 model launched in August 2023. Unfortunately, Ms. Pan's vehicle suffered a "48-volt on-board power system failure" within a few months of the launch of the facelifted GLB 220.
After inquiring about the China.com automobile complaint platform and other relevant domestic complaint platforms, the reporter found that in view of the short market time and low ownership of the 2024 GLB 220 model of the mid-term facelift, the case of "48-volt on-board power system failure" is relatively rare so far. As for whether there will be more complaints about "48-volt on-board power system failure" in the future of the facelifted GLB 220 model, the China Net Auto Complaint Platform will continue to pay attention.
