What Problems Does the 2008 Cadillac STS-V Have?
The 2008 Cadillac STS-V, while generally robust due to its performance focus, is not immune to potential issues as it ages. Common complaints or concerns often revolve around the powertrain and electronics.
One area to watch is the supercharger system. While designed for performance, like any forced induction system, it can be a source of issues if not properly maintained. This could include leaks or wear over time, though major failures are not excessively common if routine maintenance is performed.
The 4.4L supercharged V8 engine itself is a strong unit, but owners sometimes report oil leaks, particularly from the valve covers. The automatic transmission, a 6-speed unit, is generally reliable, but like any automatic, can develop issues with age, especially if fluid changes have been neglected. Shifting problems or hesitant engagement can be indicators.
Electronically, luxury vehicles of this era can present challenges. Issues with the infotainment system, navigation, or various sensors are not unheard of. The power steering system can also develop leaks or noises over time. Suspension components, while built for performance, will eventually wear, leading to clunks or less precise handling. The braking system, particularly the large Brembo units, requires specific maintenance and can be costly to repair if neglected.
Recalls for the 2008 STS-V are not extensive but have occurred. For instance, some models have been subject to recalls related to potential issues with the fuel system or airbags. It is crucial for prospective buyers to check for any outstanding recalls and ensure they have been addressed.
In terms of long-term reliability, the STS-V is considered a fairly well-built vehicle, but its performance nature means that components can be under more stress than in a standard sedan. Therefore, a thorough pre-purchase inspection by a mechanic familiar with performance Cadillacs is highly recommended. Maintenance records are also a key indicator of how well the car has been cared for.

How long will the 2008 Cadillac STS-V last?
Based on owner data and typical maintenance habits for performance luxury vehicles, a well-maintained 2008 Cadillac STS-V can reasonably be expected to achieve 150,000 to 200,000 miles or more. The engine and transmission are robust, but their longevity is heavily dependent on consistent use of high-quality synthetic oil, regular fluid changes for the transmission and supercharger, and prompt attention to any emerging issues.
Long-term durability is good for the core mechanical components, but owners should be prepared for potential wear and tear on suspension parts, seals, and electronic modules as the vehicle approaches the 100,000-mile mark. The supercharged V8, while powerful, can be more demanding on ancillary systems. Weaknesses over time often appear in areas like power steering pumps, fuel injectors, and various sensors, typical for vehicles of this age and performance class. Meticulous maintenance is the key to maximizing its lifespan.

What Technology & Safety Features are Included?
The 2008 Cadillac STS-V was well-equipped with advanced technology and safety features for its time, reflecting its luxury performance segment. Standard technology included a sophisticated Bose 15-speaker surround sound audio system, a touch-screen navigation system with real-time traffic updates, and Bluetooth connectivity for hands-free calling. A head-up display (HUD) was also standard, projecting key driving information onto the windshield, enhancing driver focus. The instrument cluster featured an analog tachometer and speedometer, complemented by digital readouts.
Driver-assistance features included front and rear parking assist sensors, which were quite advanced for the era, aiding in maneuvering the sedan in tight spaces. The StabiliTrak stability control system was standard, working in conjunction with the anti-lock braking system (ABS) and traction control to enhance vehicle control in slippery conditions or during aggressive driving.
Safety was a priority, with standard features like multi-stage front airbags, front and rear side-impact airbags, and roof-rail airbags. The body structure was designed for rigidity and energy absorption in a collision.
Optional features could have included a power sunroof, heated and ventilated front seats (Recaro seats were standard and offered these functions), and potentially enhanced audio system options, though the standard Bose system was already premium.
While specific crash-test ratings for the STS-V variant directly are not always separately published, the standard Cadillac STS on which it was based generally performed very well in government and insurance industry crash tests. For example, the 2008 Cadillac STS received top marks, including 'Good' ratings from the Insurance Institute for Highway Safety (IIHS) in frontal offset and side-impact crash tests. It also achieved 5-star ratings in frontal and side-impact crash tests from the National Highway Traffic Safety Administration (NHTSA) for the driver and front passenger. These ratings would strongly suggest the STS-V also benefited from a high level of structural integrity and safety.
