This transmission has a low failure rate. The Corolla uses a CVT transmission. More details about the CVT transmission are as follows: 1. Advantages of CVT transmission: Smooth output, high mechanical efficiency, and fuel-efficient. 2. Functions of CVT transmission: It not only has the transmission function of a conventional gasoline car transmission but can also switch seamlessly between electric and engine drive without any lag. The e-CVT system equipped in the Corolla Hybrid does not have complex components such as clutches, torque converters, or gear sets found in traditional transmission systems. Instead, it is a power distribution mechanism specifically designed for hybrid models. It can distribute engine power to both the wheels and the generator, and through seamless coordination, it controls the engine and dual-motor system, delivering a smooth acceleration experience.

Regarding the question of whether the Corolla has a high transmission failure rate, I personally have driven a Corolla for over five years and feel that the overall failure rate is not high, which is related to my regular maintenance. Toyota cars are renowned for their reliability, and their transmissions are designed to be durable, though occasional minor issues may arise. For example, older automatic or CVT transmissions may experience jerking or unusual noises after prolonged aggressive driving, but this is often caused by deteriorated fluid or improper maintenance. It is recommended to change the transmission fluid every 40,000 kilometers and avoid frequent hard acceleration while driving, which can significantly reduce the risk of problems. I know several Corolla owners who have had very few issues, with only those who neglect maintenance encountering trouble. The key is regular inspections and developing good habits to keep the transmission in top condition. Don’t expect it to be completely trouble-free, but overall, the failure rate is not high, and it can last over 100,000 kilometers without major issues.

How to Obtain the 6-Year Inspection Exemption Sticker?

There are two methods to obtain the 6-year inspection exemption sticker: 1. Bring the vehicle registration certificate, compulsory traffic insurance policy, and vehicle and vessel tax payment or tax exemption certificate directly to the nearest traffic police detachment's vehicle administration hall or the municipal vehicle management office and its branches to apply for the inspection exemption sticker. 2. For owners who don't have time to apply in person, they can apply for the inspection exemption sticker online through Alipay and choose EMS delivery to their home. Steps to obtain via Alipay: (1) Open Alipay and click on the 'More' icon on the homepage; (2) Find 'Car Owner Services' in the all applications interface; (3) Click on 'More' within the Car Owner Services; (4) Find 'Annual Inspection Appointment' in the more car owner services and click to enter; (5) In the vehicle inspection services, click on '6-Year Inspection Exemption'; (6) On the next interface, you can see the conditions for the vehicle inspection exemption service. Upload photos of the front and back of the vehicle registration certificate, a copy of the compulsory traffic insurance policy within the validity period, fill in the license plate number, registration date, delivery address, name, and mobile phone number, then pay the fee to complete the process. (Note: New vehicles within six years do not need to go to the inspection station for an on-site annual inspection; they only need to obtain the 6-year inspection exemption sticker.)

Which is the fast lane and which is the slow lane on the highway?

On highways, when there are two lanes in the same direction, the left lane is the fast lane and the right lane is the slow lane; when there are three or more lanes in the same direction, the leftmost lane is the fast lane, the middle lane is the travel lane, and the rightmost lane is the slow lane. Additional information: 1. Highway: Highways are high-grade roads, abbreviated as expressways. According to the "Technical Standards for Highway Engineering" by China's Ministry of Transport, highways refer to "roads that can accommodate an average annual daily traffic volume of more than 25,000 passenger cars, are exclusively for high-speed divided-lane driving, and have fully controlled access." Although different countries have different names for highways, they all specifically refer to roads with more than four lanes, two-way separated traffic, fully controlled access, and all-grade interchanges. 2. Traffic restrictions, exclusive to motor vehicles: Highways prohibit pedestrians, non-motorized vehicles, tractors, electric vehicles, agricultural transport vehicles, wheeled special machinery, full-trailer tractors, and motor vehicles with a designed maximum speed of less than 70 km/h from entering, being exclusively for motor vehicles; China also stipulates that the design speed of highways is generally 120 km/h. 3. Controlled access, "closed" to non-access points: Non-motorized vehicles, pedestrians, and livestock are isolated from highways using barriers, high embankments, guardrails, and other measures to "close" the highway; for intersections where vehicles are not allowed to enter or exit, separated interchanges are set up for isolation; for intersections where vehicles are allowed to enter or exit, designated interchange ramps are used for connection. 4. Divided traffic, safe and high-speed: Highways adopt a dual-carriageway form, with a central median separating opposing traffic flows to prevent head-on collisions; for traffic in the same direction, lane markings are used throughout to divide lanes, reducing interference caused by overtaking and different speeds in the same direction, which is conducive to safe and high-speed driving.

What does tc mean in a car?

tc stands for Traction Control System, which is a very important system in a car. Here is the relevant introduction: 1. Traction Control System, abbreviated as TCS, is also known as ASR or TRC. 2. It can control the car's traction by reducing the throttle opening to decrease engine power or by using the brake to control wheel slip. In cars equipped with tc, the mechanical connection between the accelerator pedal and the throttle of the gasoline engine is replaced by an electronic throttle device. When the sensor sends the position of the accelerator pedal and the wheel speed signal to the control unit, the control unit generates a control voltage signal. The servo motor adjusts the throttle position accordingly, and then feeds back the position signal to the control unit for timely adjustment of the brake. 3. The computer uses the steering wheel angle sensor to understand the driver's steering intention, and then uses the left and right wheel speed sensors to detect the speed difference between the left and right wheels; thus, it determines whether the car's steering degree matches the driver's steering intention. If understeer is detected, the computer immediately determines that the driving wheel's driving force is too high and issues a command to reduce the driving force to achieve the driver's steering intention.

What is the fuel consumption per 100 km for the Grand Cherokee?

The Grand Cherokee currently has 7 models available for sale. Among them, the 2021 3.0L 80th Anniversary Edition, 2020 3.0L Elite Navigation Edition, and Professional Navigation Edition are equipped with a 234 horsepower engine, with an NEDC fuel consumption of 9.8L per 100 km. The 2020 3.6L High-Performance 4WD Edition, Elite Navigation Edition, Flagship Honor Edition, and Luxury Navigation Edition are equipped with a 286 horsepower engine, with an NEDC fuel consumption of 10L per 100 km. The fuel tank capacity of the Grand Cherokee is 93.5L. The distance each model can travel on a full tank is as follows: Models with the 234 horsepower engine can travel 93.5/9.8*100=954km on a full tank. Models with the 286 horsepower engine can travel 93.5/10*100=935km on a full tank. Vehicle fuel consumption is directly influenced by five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption include: Driving habits: Aggressive driving behaviors such as rapid acceleration, frequent overtaking, and not easing off the throttle before reaching a red light can increase fuel consumption. The vehicle itself: Vehicles with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements typically produce more power, requiring more gasoline for combustion. Heavier vehicles also consume more fuel due to the greater driving torque needed. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, gasoline injected during a cold start does not atomize easily, requiring more gasoline for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.
