The 2018 Cadillac CTS-V is a high-performance luxury sedan, representing Cadillac's foray into the realm of track-capable vehicles. Available as a four-door sedan, it was part of the third-generation CTS lineup. While only offered in one primary trim, the CTS-V boasted numerous optional packages. New, it ranged from approximately $87,000 to $95,000. It's celebrated for its potent supercharged engine, athletic handling, and relatively luxurious interior, offering a compelling blend of performance and practicality.
The Good
The 2018 CTS-V excels in performance, delivering exhilarating acceleration and sharp handling. Its striking design and comfortable, albeit sporty, interior appeal emotionally. Practically, it offers a spacious cabin, advanced technology, and a strong reputation (though not perfect) for its engine's durability. The value proposition lies in its performance-per-dollar compared to European rivals.
The Bad
Weaknesses of the 2018 CTS-V include potential issues with the automatic transmission (specifically the 8L90), rear differential whine, and the CUE infotainment system which can be slow and buggy. Brake pad wear can be accelerated with aggressive driving. Some owners have reported issues with the supercharger isolator coupling. Pre-purchase inspections are recommended.

What Problems Does the 2018 Cadillac CTS-V Have?
Frequently reported problems for the 2018 Cadillac CTS-V often revolve around the 8L90 eight-speed automatic transmission. Owners have reported harsh shifting, shuddering, and general unreliability. While GM issued Technical Service Bulletins (TSBs) addressing some of these issues through software updates and fluid changes, the problem persists for some owners. Another common complaint is a rear differential whine, which can be noticeable at certain speeds. Some individuals have also experienced issues with the CUE infotainment system, including slow response times, freezing, and connectivity problems.
There have been recalls issued for the CTS-V, though not necessarily specific to the 2018 model year alone. Owners should check the NHTSA website for recalls specific to their VIN. Long-term reliability concerns center on the transmission and the supercharger. The supercharger isolator coupling, a common point of failure in the LT4 engine, can degrade over time, leading to rattling noises and reduced performance. Regular maintenance, including fluid changes, is crucial for mitigating these potential issues. While the LT4 engine itself is generally considered robust, proper care is necessary to ensure its longevity. Owners should also be aware of potential issues with the Magnetic Ride Control suspension system over time, as these shocks can eventually require replacement.

Owners should also be aware of potential issues with the Magnetic Ride Control suspension system over time, as these shocks can eventually require replacement.
How long will the 2018 Cadillac CTS-V last?
With diligent maintenance, a 2018 Cadillac CTS-V can easily surpass 150,000 miles or 10+ years of service. However, long-term durability hinges heavily on maintenance. Neglecting the transmission fluid, differential fluid, and engine oil can significantly shorten its lifespan. The supercharger isolator coupling is a known weakness, and its replacement should be considered proactively around 75,000-100,000 miles. The Magnetic Ride Control shocks may also require replacement around the same interval. Rust is generally not a significant issue, but corrosion in areas with harsh winters should be monitored. Overall, the CTS-V is a durable platform, but deferred maintenance can lead to costly repairs.
What Technology & Safety Features are Included?
The 2018 Cadillac CTS-V boasts a comprehensive suite of tech, entertainment, driver-assistance, and safety features. Standard tech and entertainment include the CUE infotainment system with an 8-inch touchscreen, Apple CarPlay and Android Auto compatibility, and a Bose premium audio system. Navigation is also standard. Optional features include Recaro performance seats, carbon fiber interior trim, and a Performance Data Recorder (PDR).
Driver-assistance features include automatic parking assist, lane departure warning, blind spot monitoring, rear cross-traffic alert, forward collision alert, and automatic emergency braking. Adaptive cruise control was also available as an option. Safety features include a rearview camera, multiple airbags, and stability control.
Crash-test ratings from the NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) should be consulted for specific scores. While the CTS (non-V) generally performed well, it's important to verify the ratings specifically for the 2018 model year. The CTS-V shares the same basic structure and safety systems as the standard CTS, but variations in weight distribution and performance tuning could potentially influence the results. The Performance Data Recorder is particularly notable for its ability to record driving performance metrics and video, making it valuable for track days or performance driving analysis. The head-up display (HUD) projects important information onto the windshield, helping the driver keep their eyes on the road.
