· CR-V starts to recall Dongfeng Honda and hopes to restore market confidence

Due to the influence of the "electric throttle", the CR-V was discontinued from March this year, and the recall was resumed on May 22nd. This quality crisis not only affected the annual sales plan of Dongfeng Honda, but also caused the CR-V owners to face the dilemma of vehicle recall upgrade and depreciation of used cars. In this regard, Dongfeng Honda first voiced the CR-V recall, Dong Chun Honda executive deputy general manager Zheng Chunxi said that the market will gradually restore confidence in CR-V.

Technical interpretation

Software and hardware upgrades at the same time to improve engine warm-up speed

CR-V's recall notice shows that the technical measures taken to deal with the increase in oil level are: "Replace the air conditioning control unit for the recalled vehicle, upgrade the FI-ECU software, and replace the radiator with the CVT gearbox. Water pipe assembly, upgrade TCU software."

Dongfeng Honda explained that the main purpose of the hardware replacement of the "air conditioning control unit" and the "heatsink downpipe assembly" is to increase the engine warming speed. The former is temporarily turned off to provide heat to the air conditioning system, while the latter is temporarily closed. By cutting off the water circulation of the CVT radiator at low water temperature, the cooling water is heated up faster, allowing the engine to "warm up" faster.

On the software side, upgrading the FI-ECU and the TCU upgrade around the CVT transmission version CR-V is to improve the fuel injection pressure by modifying the fuel injection timing, to promote the full combustion of the mixed gas, and to reduce the occurrence of fuel wall attachment; The change of gearbox shifting logic increases the engine speed in the low-temperature environment, promotes the engine water temperature, and cooperates with more efforts to increase the engine oil from the source.

Recall impact

The owner is worried about the loss of power and hedging rate

Dongben said that the data conforms to the standard lifetime repair and can be used safely.

Despite the detailed plan for the recall, Dongfeng Honda and the 490 special stores nationwide have established “three special services” for exclusive reception windows, special technical questions and special maintenance stations, and effectively guarantee the quality of recall operations. However, because the "electric throttle" has been going on for half a year, involving a large number of 130,000 vehicles, many consumers still have doubts about the recall.

The owner of the vehicle that has already carried out the recall operation reflected in the forum that the vehicle agility decreased and the power deteriorated after the recall. In this regard, Dongfeng Honda gave third-party data showing that after the recall, the CR-V 100-kilometer accelerated measured 8.75 seconds, the maximum speed was 194.4km/h, the acceleration noise was 69.5dB, the fuel consumption per 100km was 6.4L, and the power performance of the vehicle after the recall. Performance indicators such as economy, noise, fuel consumption, etc. meet the technical requirements / limit requirements.

The owner's perception of driving cannot be measured by standard values, and losing confidence in the product also causes some owners to prepare to sell the CR-V in their hands. However, affected by the "electric throttle", the CR-V, which was originally among the best in the used car market, was rejected during the period of suspension of sales, even if it was depreciated.

In this regard, Zheng Chunyi said that Dongfeng Honda promised to provide lifelong repair service for the main parts of the vehicle engine involved in the recall. This ensures that the user can use the car in the future and can effectively maintain the stability of the CR-V used car.
