Safety features are comprehensive, including curtain airbags for all rows, knee airbags for the first row, and side airbags for both the first and second rows. This luxury sedan combines safety and power, making it an impressive choice for discerning drivers.

Spec:

Engine Model

LT4 - DI: Direct Injection, SC, AFM, VVT, ALUM

Engine Number of Cylinders

Problems:

Oil consumption

The LT4 engines are known for higher-than-average oil consumption due to their high-performance nature and forced induction system.

Carbon buildup

Direct Injection (DI) engines, like the LT4, can suffer from carbon buildup on the intake valves because fuel doesn't wash over them as in port-injected engines.

Supercharger issues

The supercharger on the LT4 can sometimes develop issues, such as bearing failures or coolant leaks, affecting performance.

Active fuel management (afm) problems

The AFM system, which deactivates cylinders to improve fuel economy, can sometimes lead to lifter failures or other mechanical issues.

Variable valve timing (vvt) issues

Problems with the VVT system can cause performance issues or trigger check engine lights if the timing doesn't adjust correctly.

Coolant leaks

The LT4's aluminum block and cylinder heads can be prone to coolant leaks, especially around the gaskets and seals.

Overheating

High-performance engines like the LT4 can sometimes face overheating issues due to the additional thermal load from the supercharger and high output.
