The BYD Dolphin Mini of a rideshare driver in Goiânia experienced failures in under 30 days, stopped charging at the Wallbox, and displayed electrical alerts, ABS, and LVPS; after a diagnosis, the authorized network attributed the damages to external agents and presented a quote of R$ 18,800 for repairs.
A BYD Dolphin Mini with less than a month of use began to exhibit a series of problems reported by a rideshare driver in Goiânia, Goiás. The complaint was published on May 4, 2026, and described a malfunction in the air conditioning, refusal to charge at the Wallbox, and the appearance of alerts on the dashboard before the vehicle was taken to the authorized network in Aparecida de Goiânia.
Four days later, on May 8, BYD publicly responded that the analysis conducted by the authorized network did not identify defects arising from manufacturing or assembly. According to the company, the damages found resulted from the action of external agents, and therefore, the repair was not covered by warranty.
BYD Dolphin Mini Began to Experience Issues in Less Than a Month
According to the owner, the first abnormality occurred when the air conditioning suddenly stopped working on a Sunday. The vehicle had been purchased less than 30 days prior and was being used as a tool for work.

The consumer stated he relies on the BYD Dolphin Mini to perform his tasks as a rideshare driver. Therefore, in addition to concerns about such a new car, its unavailability began to directly impact his professional routine.
Car Stopped Accepting Charge from the Wallbox
Less than a week after the air conditioning failure, the owner reported a different problem. When connecting the vehicle to the Wallbox, the system did not start charging as expected.
Upon activating the dashboard, three alerts appeared as mentioned in the complaint: failure in the electrical system, ABS, and LVPS. The source does not technically detail the origin of each alert nor does it allow for asserting that all were caused by the same issue.
Vehicle Taken to Authorized Network in Aparecida de Goiânia
Given the sequence of alerts, the driver submitted the BYD Dolphin Mini for evaluation at a dealership located in Aparecida de Goiânia.
According to his account, there was an initial estimate of 48 hours for the diagnosis, but the timeframe was reportedly not met. The consumer also complained about the difficulty of obtaining information while remaining without the vehicle used for work.
Diagnosis Indicated Action of External Agent
After the analysis, the owner reported being informed that there was damage to the front wiring harness of the vehicle related to an external agent. In the complaint, he mentioned possible rodents as a hypothesis that was suggested during the service.
In a subsequent public response, however, BYD adopted a broader formulation. The automaker stated that the identified damages were due to the action of external agents, without specifying in its statement on Reclame Aqui which agent caused the problem.
BYD stated no manufacturing or assembly defects were found
The company’s position was recorded in response to the consumer on May 8. According to BYD, the assessment conducted by the authorized network concluded that the vehicle did not present defects originating from manufacturing or assembly.
This conclusion was decisive for the warranty analysis. Since the automaker classified the damage as resulting from an external cause, the company informed that the necessary parts and services for repair would be the responsibility of the owner.
Repair estimate reached R$ 18.8 thousand
The driver reported receiving an estimate of R$ 18,800 for the necessary repairs. The amount caught his attention especially because the BYD Dolphin Mini had been in use for less than a month.
In his final consideration published on the platform, he again challenged the price and the warranty denial. The consumer claimed that a significant portion of the estimate was related to the wiring harness and another part to labor, but the itemized amounts did not appear to be confirmed by the company in the response reproduced by the source.
Driver claimed to lose around R$ 400 per day
In addition to the repair costs, the owner linked the vehicle’s downtime to lost income. According to his calculations, he was missing out on about R$ 400 per day while without his main work tool.
He also mentioned the offer of a fuel-powered rental car but stated that this alternative would hurt his profit margin due to gas expenses. This assessment reflects the economic impact presented by the driver in the complaint.
Warranty became the main point of contention
The consumer requested that the repair be covered under the warranty of the BYD Dolphin Mini, arguing that the vehicle had been used for very little time and he should not bear a loss close to R$ 20,000 at that moment.
BYD, on the other hand, cited its warranty policy and reiterated that coverage includes necessary repairs to correct defects in materials or services provided by the automaker. In the company’s assessment, this case would not fit within that condition as it involves external damage.
Complaint ended marked as unresolved
After the company’s response, the consumer recorded their final consideration and maintained a negative evaluation of the service. On the platform, the case remained labeled as “unresolved”.
The automaker responded again, reiterating the same conclusion: no manufacturing or assembly defect had been found, and the costs would remain the owner’s responsibility due to the classification of the damage as resulting from an external agent.
Case highlights difference between reported fault and attributed cause
The episode involves two points that need to be separated. On one side, there is the report that the BYD Dolphin Mini experienced issues within less than 30 days of use, including climate control failure, refusal to charge, and alerts on the dashboard.
On the other hand, there is a discussion regarding the origin of these problems. The source does not allow for an independent conclusion that rodents caused the damage, nor does it prove a manufacturing defect. What is documented is the conflict between the consumer’s interpretation and the diagnosis adopted by the authorized network and the automaker.
BYD Dolphin Mini leaves owner facing a budget of R$ 18.8 thousand
The case began with a practically new car used daily by an app driver and ended, according to the complaint, with the BYD Dolphin Mini immobilized, a budget of R$ 18.8 thousand, and the denial of warranty coverage after the network attributed the damages to an external cause.
The situation raises a relevant discussion about warranty expectations, technical diagnosis, and unexpected costs in new vehicles. In your opinion, in a case like this, who should present more detailed evidence regarding the origin of the damage: the consumer, the dealership, or the automaker itself?
