What Causes the Electric Tailgate of the Envision to Make Abnormal Noises?
2 Answers
The relationship between abnormal noises from the electric tailgate of the Envision and engine speed Most common abnormal noises in the engine depend on the engine's speed state. Below are the specific causes: Excessive gap between the piston and cylinder wall: The abnormal noise only occurs at idle or low-speed operation. Causes of the noise include: excessive gap between the piston and cylinder wall, overly tight assembly of the piston pin or connecting rod bearing, excessive gap between the tappet and its guide hole, wear on the camshaft profile, and sometimes, a loose starter causing the pulley to make noise (noticeable when speed changes). Broken crankshaft: The noise becomes chaotic when maintaining a certain speed, and short noises are emitted successively during rapid deceleration. Causes of the noise include: cracked camshaft timing gear or loose fixing nut, broken crankshaft, loose piston pin bushing, excessive axial clearance of the camshaft or loose camshaft bushing.
My Envision has been making squeaking noises when opening and closing the electric tailgate for over a year, which is quite annoying. There are several common causes: First, it might be due to dried-out lubricant or rust on the tailgate hinges or linkages, as these metal parts frequently rub against each other, especially after humid weather. Second, the motor or gears could be malfunctioning, worn out, or clogged with dust, causing rough operation. Third, loose assembly, such as screws or deformed seals, can create friction noises under pressure. Fourth, excessive force when loading heavy items or sand and dust trapped in the gaps can also be culprits. I tried applying lubricant myself, but it only provided temporary relief. Eventually, I took it to the dealership, where the technician replaced some parts to fix the issue. My advice is not to delay and to schedule regular maintenance.
