What causes the body shaking of the Envision?
2 Answers
Envision body shaking is caused by insufficient power due to incomplete fuel combustion. The main reasons for idle shaking include severe engine carbon deposits, ignition system issues, unstable oil pressure, and aging engine components. The Envision model offers two displacement options: 1.5T and 2.0T, each available in both two-wheel drive and four-wheel drive versions. The 1.5T is paired with a 7-speed dual-clutch transmission, while the 2.0T comes with a 6-speed automatic manual transmission. The Envision engine type is a direct-injection turbocharged engine. In terms of body dimensions, the Envision measures 4686mm in length, 1839mm in width, and 1660mm in height.
When I drove the Enclave, I also experienced body shaking. Let me tell you about the common causes. For older cars, the most common issues are with the engine, such as worn-out engine mounts. Once these fail, the vibrations from the engine are directly transmitted to the body. Bad spark plugs or faulty ignition coils can also cause the engine to run unevenly, resulting in jerky movements. If the steering wheel shakes at high speeds, it's likely due to unbalanced tires—uneven tire weight distribution causes this. Also, don’t overlook the drive shafts, especially the universal joints inside the axle heads; severe wear can lead to failure. Additionally, excessive carbon buildup in the throttle body or fuel injectors can cause annoying shaking at idle. This issue really needs to be addressed early—prolonged shaking not only damages the car but also makes driving nerve-wracking.
