Legitimate 4S stores would not engage in such practices. Below is relevant information about 4S stores: 1. Introduction: A 4S store, fully named Automobile Sales Service 4S Shop (Automobile-Sales-Servicshop-4S), is an integrated automotive sales enterprise combining vehicle sales (Sale), spare parts (Sparepart), after-sales service (Service), and information feedback (Survey). 2. Demand: The emergence of 4S stores precisely meets various customer needs. They provide well-equipped and clean maintenance areas, modern facilities and service management, a highly professional atmosphere, well-maintained service facilities, ample spare parts supply, and a prompt and efficient tracking service system. Through the services offered by 4S stores, customers can develop trust in the brand, thereby increasing sales.

I've driven several cars and visited quite a few 4S dealerships before. To be honest, most places are pretty reliable since they rely on reputation to stay in business. Tampering with your catalytic converter is really unlikely. The catalytic converter is part of the exhaust system—if it were swapped out, the owner would easily notice increased noise or failed emissions tests, and the deception would be exposed. Plus, shops nowadays have cameras and recording systems, so employees would risk getting fired if they tried anything shady—it’s just too risky. I remember once when I took my car in for an exhaust issue, the mechanic proactively showed me the old part to give me peace of mind. That said, some small shops might try to make extra money on the side since catalytic converters contain valuable precious metals, but that’s highly unlikely at major chain 4S dealerships—just pick a reputable place. Bottom line: don’t worry too much. Stay alert for unusual vehicle symptoms or take photos before repairs as proof, and you’ll be much safer.

Should a Punctured Tire Be Repaired or Replaced?

Tire punctures should be addressed based on the specific situation: if the puncture is on the tread, it can be repaired; if the puncture is on the sidewall, the tire should be replaced. Functions of tires: 1. Transmit driving force, braking force, and steering force to enable vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving. Precautions for tire replacement: 1. Identify the front and back sides of the tire; 2. Choose tires of qualified quality; 3. Replace the valve stem simultaneously; 4. Determine the installation direction; 5. Install new tires on the rear axle of the vehicle; 6. Avoid sudden braking after replacing a new tire; 7. Remove screws diagonally when removing the tire; 8. Perform a four-wheel alignment when replacing tires.

What Causes Engine Breather Pipe to Spray Engine Oil?

There are several main reasons why an engine breather pipe sprays engine oil: 1. Issues with the crankcase ventilation system: The simplest troubleshooting method is to directly pull out the oil dipstick and check if engine oil is spraying out from the dipstick tube. If so, it indicates a damaged PCV valve. 2. If the vehicle's breather pipe is connected to the upper part, then valve stem seal issues should be considered: Generally speaking, engine oil discharge from the breather pipe is due to excessive crankcase pressure. If the engine was recently serviced and there was residual oil in the cylinders, some oil discharge may occur temporarily. However, if oil leakage persists after prolonged operation post-repair, it may be caused by wear in the turbocharger's floating bearing seals leading to oil leakage.

Will starting the car in D gear cause damage?

Starting the car in D gear can cause damage. D gear is the forward gear, and many modern automatic transmission vehicles are equipped with automatic detection systems that usually prevent the engine from starting in D gear. Forcibly starting the engine in D gear may harm the vehicle. The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions. Whether manual or automatic, more gears usually mean better fuel efficiency. More details are as follows: 1. Automatic transmissions use planetary gear mechanisms to shift gears automatically based on throttle pedal position and vehicle speed changes. The driver only needs to control the speed with the accelerator pedal. 2. Generally, the commonly used automatic transmissions in vehicles include the following types: hydraulic automatic transmissions, hydrostatic automatic transmissions, electric automatic transmissions, stepped mechanical automatic transmissions, and continuously variable mechanical automatic transmissions.

How to Identify Inventory Vehicles?

Methods to identify inventory vehicles are: 1. Check the production nameplate: There is a vehicle nameplate below the B-pillar on the right side of the vehicle, which indicates the vehicle production date, engine parameters, and other information; 2. Check the glass: The car glass will have the production date and year marked on it; 3. Check the tires: Determine the production time through the tire's production date; 4. Inspect the engine compartment: Open the engine and check if the engine is clean. Precautions when buying a car: 1. Choose the brand and model; 2. Select a price range; 3. Communicate rationally with the salesperson; 4. Choose the configuration; 5. Pay attention to the contract; 6. Check if the car's relevant documents are complete; 7.

Is the Electronic Parking Brake Prone to Malfunction?

Generally speaking, the electronic parking brake is not prone to malfunction. However, if the car experiences severe power loss, the electronic parking brake may fail to function due to insufficient power. The electronic parking brake is a technology that uses an electronic system to control the vehicle's parking brake, achieving the same effect as a mechanical handbrake but with a different control method. Its advantages include saving the space occupied by a mechanical handbrake, creating more central console space; simple operation and effort-saving; and adding multiple functions such as auto start-stop and hill-start assist. More details are as follows: 1. Activating the electronic parking brake: When the car is stopped, shift to P or N gear, press the brake pedal, and pull up the electronic parking brake switch until the indicator light comes on. If the car is turned off without activating the electronic parking brake, most vehicles will automatically engage the electronic parking brake. 2. Deactivating the electronic parking brake: Press the electronic parking brake switch while holding down the brake pedal. When the indicator light turns off, it means the electronic parking brake is deactivated.
