With the increasingly stringent emission regulations and the policy advantages of new energy models in terms of licensing, many manufacturers have also followed this trend and launched plug-in hybrid or oil-electric hybrid models. Although there is a difference in the license plate between plug-in hybrids and ordinary gasoline-electric hybrids, in the general direction, the goal of reducing the fuel consumption and carbon emissions of vehicles is to be pursued.
Although hybrid technology has been introduced for more than 20 years, each manufacturer still has its own way of reflecting hybrid power, and the technical and technological aspects are also changing with each passing day. However, the most worrying thing for consumers is whether the battery is durable, whether the electric drive part is safe, and recently many hybrid models have issued recall notices, let's take a look at what problems have occurred in these hybrid models.
# Toyota twin engine hybrid model #
In December last year, a number of models issued recall messages, Toyota alone will recall nearly 900,000 vehicles, and all of them are dual-engine hybrid models, which is also the largest recall in December. The recall notice has affected almost all Toyota and Lexus hybrid models currently on sale in China, including CH-R, Yize, Camry, Rongfang, Asian Dragon, Veranda and Lexus ES and UX, totaling more than 890,000 vehicles, except for the Corolla and Ralink.
Reason for recall: The internal components of the engine exhaust gas recirculation valve (EGR valve) of the vehicle within the scope of this recall may be corroded by the higher concentration of chlorine in the fuel, resulting in poor valve body movement. Engines can run poorly, and in extreme cases, vehicles can stall at low speeds, increasing the risk of collisions.
How to deal with it: Toyota will replace the modified EGR valve assembly free of charge for the affected vehicles. Before the recall and maintenance is carried out, in case of engine failure lights lit up and abnormal engine shaking, it is recommended that the owner contact the 4S shop in time for maintenance.
# Nissan & Infiniti hybrid model #
Nissan's hybrid model may not react to many people at once, that is, the Dongfeng Nissan Loulan model is with HEV hybrid, and Nissan's high-end car Infiniti's QX60 is also equipped with a hybrid engine. The recall list includes 11,822 Dongfeng Ri product brand new Loulan HEV vehicles produced from September 26, 2014 to July 30, 2021, and some imported Infiniti QX60 hybrid vehicles produced from April 17, 2014 to November 3, 2020, with a total of 27,133 units and a total of 38,955 units.
Reason for recall: Due to the insufficient setting of the hybrid system control software in the vehicle within the scope of this recall, when the drive motor bearing is damaged and the speed difference between the engine and the drive motor is too large, a specific fault code will be triggered, and the control strategy according to this fault code will stop the operation of the engine and the motor, resulting in power interruption during the vehicle driving, and there is a safety hazard.
Treatment: Free upgrade of hybrid system control software for vehicles within the scope of the recall to eliminate safety hazards.
Emergency measures: Before the vehicle recall and maintenance, the user should drive carefully, if the vehicle transmission is found to be abnormal, it should contact the Infiniti authorized dealer in time to deal with it.
# Venucia D60EV/T60EV electric vehicle #
Dongfeng Motor Co., Ltd. decided to recall 1,136 Dongfeng Nissan Venucia brand D60EV and T60EV electric vehicles produced from May 8, 2021 to July 20, 2021, starting from December 10, 2021.
Reason for recall: Due to the manufacturer's manufacturing reasons, the relay parts of the high-voltage distribution box in the power battery pack are not welded enough, and the welding parts may break after long-term durable use, resulting in the relay not working. If the relay welding part is broken during the driving process of the vehicle, it will cause the interruption of the vehicle power and there is a safety hazard.
Handling method: Dongfeng Motor Co., Ltd. will check the batch number of the high-voltage distribution box in the power battery pack for the vehicles within the scope of the recall free of charge, and replace the parts belonging to the risk batch with qualified parts to eliminate safety hazards.
# Write at the end #
Fortunately for Brother Understand, in this batch of recall lists in December, there is no recall notice of domestic hybrid models. In the first two years, the BMW 530Le also broke out a large-scale recall, so that many people choose hybrid models still have a thorn in their hearts. However, with the development of hybrid technology, especially independent brands such as BYD have increased their investment in science and technology, solving the difficulties of a series of hybrid models.
I hope that the hybrid models of independent brands can create brilliant achievements again, strive to achieve cornering overtaking, and let the people be assured of choosing.
