What are the common issues with the 12th-generation Crown?

[ColinFitz]

One common issue with the 12th-generation Crown is that the dashboard is prone to cracking. Here are some related details: 1. The Crown is a mid-to-high-end model under Toyota, with the 12th-generation Crown launched in 2010. 2. It is equipped with a 3.0L V6 engine, dual VVT-i, and a 6-speed AT transmission, among other features. 3. The chassis adopts a fully independent suspension system, providing excellent comfort. The engine's intake efficiency, fuel economy, and power performance are outstanding, with ample horsepower. 4. The Crown measures 5020mm in length, 1805mm in width, and 1480mm in height, classified as a 4-door, 5-seater sedan. It comes with a 2.5L V6 or a 2.0T L4 engine.

When I drove the 12th-generation Crown, I encountered quite a few minor issues. The most annoying was the rapid engine oil consumption, especially after exceeding 100,000 kilometers—the VVT-i system was prone to clogging, leading to oil burning, and I had to top it up regularly. Aging rear air suspensions were also common, particularly during the rainy season when air leaks caused noticeable body sagging, making rides over bumps uncomfortable. The air conditioning control board frequently malfunctioned, suddenly blowing hot air in summer, which was very irritating. The transmission occasionally hesitated during gear shifts, with strong jerks during acceleration. The interior paint and seat coatings degraded over time, becoming sticky to the touch. While the car was generally durable, these issues affected the overall experience. I recommend a thorough inspection of these points before buying a used one, and timely maintenance can help reduce trouble.

At repair shops, it's common to see 12th-generation Crown owners bringing their cars in for maintenance, with engine issues being the most prevalent. The VVT-i oil passages are prone to clogging, leading to excessive oil consumption—minor cases require cleaning, while severe ones necessitate part replacements. The rear suspension airbags often age and leak, causing the car body to tilt or become unbalanced, requiring an airbag kit replacement to resolve. The air conditioning control module frequently malfunctions, with unresponsive panel buttons or erratic airflow, mostly due to poor circuit board contact. Transmission shift lag is also widespread, especially in the 4-speed automatic models, with noticeable jerking during upshifts. Another issue is the sticky and faded interior trim, which can't be fixed by cleaning alone and must be replaced. Regular oil changes and electrical connection checks during maintenance can help prevent these problems.

Forum members often mention several common issues when discussing the 12th-generation Crown: significant engine oil consumption, VVT-i system design flaws requiring maintenance; rear suspension airbags prone to leaks, leading to unstable driving; air conditioning electronic panels prone to failure, causing functional chaos that drives people crazy; the outdated 4-speed transmission may lag or shift roughly; interior sticky materials degrade, becoming glue-like after a few years. Although the car is sturdy, these problems make maintenance costs for older models relatively high.

From a technical perspective, the VVT-i actuator in the 12th-generation Crown engine is prone to carbon buildup and clogging, affecting oil pressure and increasing oil consumption. The rear air suspension airbags are susceptible to material aging, leading to cracks and air leaks, requiring replacement parts. Frequent failures occur in the air conditioning control unit circuitry due to loose connections or component failures. The 4-speed automatic transmission torque converter may exhibit delayed response. The interior coating oxidizes, causing a sticky surface that is difficult to repair after chemical decomposition. These common issues stem from design and aging factors, and regular inspection of key components can help delay their occurrence.

Having driven the 12th-generation Crown for many years, it offers comfort but has some common issues. The engine noticeably burns oil, especially requiring top-ups after long trips, which is caused by a defect in the VVT-i system. The rear air suspension is prone to air leaks, causing increased body sway on uneven roads. The air conditioning frequently malfunctions, with unstable cooling affecting usability. The transmission shifts less smoothly, occasionally jerking during acceleration. The interior materials become sticky as they age, making cleaning difficult. Despite its good quality, these minor issues remind us that timely maintenance is essential for worry-free driving.
