Currently, the cylinder scoring issue with the Hyundai ix35 engine has shown improvement. Symptoms of cylinder scoring in the Hyundai ix35 engine include: 1. Noticeable decrease in vehicle power under normal conditions (commonly referred to as lack of power); 2. Abnormal water temperature (the engine shows high temperature or even boils shortly after starting); 3. Increased exhaust from the lower part, with blue smoke visible from the rear exhaust; 4. Abnormal noises during engine operation (rough and muffled sounds, unstable idle, requiring higher fuel supply to maintain idle); 5. Prolonged idling or short driving distances leading to cylinder misfire or failure. Additional information about cylinder scoring is as follows: 1. Cylinder scoring is one of the common faults in car engines. 2. So-called 'cylinder scoring' refers to deep grooves being formed on the inner walls of the cylinder, causing the piston and piston rings to lose their sealing ability against the cylinder walls, thereby reducing cylinder compression pressure and losing power. The leakage of combustible mixture increases the crankcase pressure, which can lead to crankcase explosion in severe cases.

As a long-time driving enthusiast, I've noticed that early models of the Hyundai ix35 did indeed have reported issues with engine cylinder scoring, particularly in the 2015-2017 Theta II engine variants. This was caused by a design flaw in the connecting rod bearings, often leading to abnormal noises and power loss. Hyundai implemented a global recall in 2019, offering free inspections and replacement services, which effectively resolved most of the potential risks. The newer ix35 models, such as the upgraded versions post-2020, have optimized engines and rarely encounter similar issues now. Owners should immediately check their VIN on the official website to confirm recall status and visit authorized service centers for inspection. During routine maintenance, pay attention to abnormal oil consumption and ensure regular oil and filter changes to prevent wear and guarantee driving safety. Overall, the issue has largely been fixed, but don't let your guard down—early inspection brings peace of mind.

Are small cars exempt from inspection within ten years?

Small cars are not exempt from inspection within ten years. Currently, the exemption period remains six years. The six-year exemption applies to standard-compliant vehicles registered within six years, which do not require safety technical inspections at inspection agencies when undergoing biennial periodic inspections. Instead, owners can directly apply for inspection labels from the traffic management department of the public security authority. Vehicle owners only need to bring their driver's license, ID card, and other relevant documents. If a car is driven on the road without the new inspection label, the owner may face penalties from traffic authorities for failing the annual inspection. The six-year exemption rule for new cars is limited to 5-seater and 6-seater vehicles.

How to Move the Heel When Releasing the Clutch?

The method for moving the heel when releasing the clutch is: Place the toes on the clutch pedal with the heel naturally resting on the ground. Ensure that when the clutch pedal is fully depressed, the thigh and calf form a naturally curved arc. If the leg is not long enough when pressing the clutch pedal, and the heel remains in place while only the toes press the pedal, this can easily lead to insufficient force and slipping, so seat adjustment is also crucial. The method for using the clutch is: After pressing the clutch and shifting gears, if the car's speed has not yet increased, the clutch should be released slowly. Releasing the clutch too quickly can cause the engine to stall. When starting on a slope, slowly release the clutch until the engine vibrates, then release the brake pedal and immediately press the accelerator to follow up.

What is the correct way to shift gears in a C1 vehicle?

The correct way to shift gears in a C1 vehicle is: 1. To shift into 1st or 2nd gear, place the palm of your right hand facing left, and with the exception of the thumb, gently press the remaining four fingers against the left side of the gear lever, moving it forward or backward to engage 1st or 2nd gear. 2. For 3rd or 4th gear, simply push the gear lever lightly. 3. To shift into 5th gear or reverse, gently press the thumb of your right hand against the gear lever, moving it to the right side before pushing it forward or backward to engage the gear. 1st gear is used for normal starts or climbing hills, with a speed typically around 10 km/h. 2nd gear serves as a transitional gear for acceleration after starting and is used for low-speed driving, with a speed generally around 20 km/h.

What Causes the Gurgling Rolling Sound While Driving?

The gurgling rolling sound while driving originates from the suspension system in the chassis, indicating issues such as looseness, aging, or shock absorber failure in components like ball joints, rubber bushings, or shock absorbers. When this phenomenon occurs, it is advisable to take the vehicle to a repair shop to inspect whether the ball joints are loose or the bushings are cracked. Additionally, a wireless electronic stethoscope can be used to monitor noise decibel levels from other suspension components to identify the source of the gurgling sound. To address the gurgling rolling sound, owners should promptly clean the sliding rails. The sunroof's sliding mechanism is track-based, and over time, dust and sand particles accumulate in the contact surfaces and gaps of the rails. If not cleaned regularly, the "gurgling" sound will persist. Owners can use cotton cloth or gauze to wipe the rail tracks and apply a small amount of grease after cleaning.
