Mr. Li from Fuzhou is here.
The WeChat mini-program of the "First Gang" of the political platform.
said that he bought a Porsche Cayenne in May 2022. At the beginning of 2024, he found that the car door could not be opened, but the test results and treatment plan given by the 4S store were unacceptable to him.
The vehicle cannot be started.
The after-sales test results are unacceptable to the car owner.
Mr. Li said that he spent nearly 1.3 million yuan to buy the Porsche, and drove about 5,000 kilometers in a year and a half. On January 31, 2024, he suddenly noticed that the car would not start and the doors would not open.
The next day, Mr. Li found out that the same situation had occurred again.
Mr. Lee. Porsche Aftermarket asked us to drive the car over for testing. On February 4 this year, they contacted us through WeChat after sales, saying that it was man-made damage, because a charging cable was inserted into the cigarette lighter, and the short circuit of the charging cable caused damage to the battery.
Mr. Li felt that it was fair use and did not agree with the reasons given by the after-sales service.
Mr. Lee. I use it in other cars as well, and none of them say it's because of a charging cable. I have contacted the 4S store many times for this matter, and they all said that it was my artificial reason, and I felt very strange and a bit insulting to IQ.
In this regard, auto repair experts said that the normal use of the car charger will not cause damage to the battery.
Normal situation from the vehicle low-voltage battery design process, the vehicle is normal in the process of driving, it must have a 12 volts, car self-charging has been charging, this charging it has been supplementing, low-voltage management battery, some comfort systems in the car, such as audio or as you said, the power supply of the cigarette lighter, it is a 12 volt power supply, usually the charger through the cigarette lighter voltage, generally a 12 volt to 35 volts, such a low-voltage electricity, usually the situation is to charge the mobile phone, so this is impossible, resulting in a short circuit such a statement, each of our systems, it has an independent fuse fuse, the cigarette lighter short circuit inevitably has some load short circuit, then the cigarette lighter fuse, it has a maximum of 20 amperes, such a fuse, it will burn out, it will not cause damage to our starting battery, only when the vehicle is not startedIf the existing storage is enabled for a long time, 12 volts of electricity for transformer charging will cause the power storage to be too low, otherwise it is impossible, and this will take a long time.
After-sales: Abnormal discharge of the car charger.
Subsequently, the mediation team came to the Porsche Centre Fuzhou Minjiang to understand the situation. The after-sales staff of the 4S store said that they ruled out the problem of the vehicle itself and detected that the on-board charger had abnormal discharge in the flame-off state, which was 2 to 3 times higher than the standard value. They believe that the abnormal discharge of the car charger caused the car battery to lose power.
4S shop after-sales staff.
There are two common situations that cannot be started due to power loss: the first may be that the power is exhausted, and the second may be that the car has leakage and causes abnormal discharge. When the car enters the yard.
The battery is no longer able to hold electricity and is damaged.
When we detected, there was an abnormal discharge in the background; When we unplug this thing, its discharge value goes down instantly, and the normal low current will not cause the power to drain so quickly.
On-site test of on-board charger discharge.
In this regard, the mediation team proposed to conduct an on-site test of the discharge of the on-board charger to verify the claims of the 4S shop.
Subsequently, the mediation team tried to replace it with another on-board charger for testing.
Mr. Li still doesn't think it's a problem with the on-board charger.
In this regard, auto repair experts said that in the case of small current, it will not lead to abnormal power consumption.
80 mAh will not cause this abnormal power consumption, if in such a short period of time, our internal cause belongs to the abnormal power consumption, then it must be a large current or a short circuit, which will lead to abnormal current power consumption, then if this small current situation, it is impossible to exist so that it has power consumption so fast, its head is an inverter, it objectively exists on the top will consume some electricity, but it will not consume much It will not cause the battery to fail.
Mr. Li said that he could not accept the various explanations given by the after-sales personnel.
Owner: 4S shop gives the battery ** for 16,940 yuan.
The after-sales staff said that because Mr. Li's vehicle was parked for a long time and was not used very frequently, the internal power storage of the lithium battery was relatively small, and the abnormal discharge of the charger could lead to damage to the battery. However, Mr. Li believes that there is a problem with the quality of the battery itself, and it is still under warranty, and the 4S shop should replace it for free.
In this regard, the after-sales staff said that this was not caused by the vehicle's own problems, and it was impossible to claim from the manufacturer through the warranty, and the 4S shop could not repair it, so Mr. Li could only replace it at his own expense.
As for the cause of the battery damage, the two parties have their own opinions, and Mr. Li hopes that the 4S store will issue written materials on the cause of the damage to the vehicle battery.
Subsequently, the 4S store wrote in the remarks of the service pre-sale statement issued by the 4S store that the external charging equipment of the vehicle caused excessive power consumption of the dormant current, which was more than twice the standard value and caused the battery to be damaged by power loss.
The mediation team recommended that Mr. Li continue to protect his legitimate rights and interests through legal and reasonable means.
