The Good
The 2006 CTS offers engaging rear-wheel-drive performance, especially the powerful V8 CTS-V, appealing to emotional buyers. Its distinctive "Art and Science" design remains stylish. Practical advantages include a comfortable, well-appointed interior and excellent used market value, making luxury and sporty dynamics highly accessible for budget-conscious buyers seeking premium features without the new car price tag.
The Bad
Known weaknesses include potential timing chain issues and oil leaks, particularly with the 3.6L V6. Electrical gremlins, such as power window failures and dash issues, are also common. Interior plastics can feel dated, and suspension components may require attention over time. Maintenance costs can be higher than expected for a used car.

Analysis
What Problems Does the 2006 Cadillac CTS Have?
Oil leaks are also prevalent, especially from the front timing cover gasket and valve cover gaskets. These leaks can be significant and, while not always mechanically critical immediately, can lead to lower oil levels and require messy and somewhat labor-intensive repairs.
Electrical issues are another common complaint. These can manifest as problems with power windows (regulators failing), malfunctioning door lock actuators, issues with the infotainment system (CD changers, radio displays), or various warning lights illuminating without clear cause. The instrument cluster can sometimes develop issues with gauges or backlighting.
The suspension components tend to wear out over time, leading to clunks or squeaks, especially from bushings, ball joints, and tie rods. This is somewhat expected with higher mileage but can be accelerated by aggressive driving or poor road conditions.
Regarding recalls for the 2006 model year, specific recalls have been issued, including:
- Ignition Switch Recall (NHTSA Campaign Number: 14V355000): This broad GM recall affected numerous models, including the CTS, where the ignition switch could inadvertently move from the "run" position, causing the engine to stall and disabling power steering, power brakes, and airbags.
- Headlamp Wiring Harness (NHTSA Campaign Number: 05V288000): For early 2006 models, a potential issue with the headlamp wiring harness causing intermittent or complete loss of low-beam headlights.
How long will the 2006 Cadillac CTS last?
Long-term durability is generally good for the chassis and drivetrain if significant engine issues (like timing chain problems on the 3.6L V6) are either absent or have been professionally addressed. Over time, expect wear and tear on suspension components (bushings, struts, ball joints), which will eventually need replacement. Electrical components can become finicky with age, leading to minor but annoying failures like power window regulators or dashboard display issues. Interior materials, while generally good, may show signs of wear, cracking, or fading depending on sun exposure and care. The 6.0L V8 in the CTS-V is renowned for its robustness and can easily exceed 200k miles with proper care.
What Technology & Safety Features are Included?
Entertainment and Connectivity:
- Standard on most models was a Bose premium audio system, often with an AM/FM stereo and a multi-disc CD changer.
- An optional navigation system with a pop-up LCD screen was available, a relatively advanced feature at the time.
- Satellite radio (XM) was an available option, providing a broader range of audio entertainment.
- Power outlets were typically available for charging devices.
- Dual-zone automatic climate control was standard, allowing separate temperature settings for driver and front passenger.
- Power-adjustable front seats were standard, with memory functions for the driver's seat available on higher trims.
- Power windows, door locks, and heated power mirrors were standard.
- Optional features included power-adjustable pedals, heated front seats, and a power sunroof.
- Cruise control was standard.
- Rear parking sensors were an optional driver-assistance feature.
- Standard safety equipment included dual-stage front airbags, front side-impact airbags, and full-length side curtain airbags.
- Four-wheel anti-lock brakes (ABS) were standard.
- Traction control and StabiliTrak electronic stability control were standard features, crucial for maintaining control in adverse conditions.
- The CTS also featured a tire pressure monitoring system.

What Colors Options are Available?
2006 Cadillac CTS Prices and Market Value
Today, current used market prices are significantly lower, reflecting substantial depreciation. Standard V6 models in good condition usually fetch between $3,000 and $8,000. The performance-oriented CTS-V, however, commands a premium due to its powerful V8 and limited production, with prices typically ranging from $12,000 to $25,000 or more depending on condition, mileage, and originality.
Factors affecting resale value include the vehicle's overall condition, maintenance history, mileage, and specific trim (CTS-V holds value much better). Cadillac models generally depreciate faster than some European or Japanese luxury rivals. The 2006 CTS has absorbed most of its depreciation, making it an attractive used purchase, but older luxury cars incur higher maintenance costs, impacting their perceived long-term value.

How Does the 2006 Cadillac CTS Compare to Other Sedan?
Performance: The CTS, particularly with its 3.6L V6, offered strong straight-line performance comparable to V6-equipped rivals. Its rear-wheel-drive platform provided engaging handling. The CTS-V stood in a league of its own, outperforming M3s and C-Class AMGs of its era with its potent 400hp LS2 V8, making it a true American muscle-sedan. The BMW 3 Series was often lauded for superior driving dynamics, while the Mercedes C-Class typically prioritized comfort.
Features: The CTS came well-equipped, often matching or exceeding the standard features of its base German competitors, especially concerning interior amenities. German rivals often had more refined interior design and higher perceived material quality, though the CTS's "Art and Science" exterior was arguably more distinctive. The Lexus IS offered exceptional interior refinement.
Reliability: This is where the CTS often lagged, especially compared to the renowned reliability of the Lexus IS. Known issues with timing chains (3.6L V6), oil leaks, and electrical gremlins sometimes make it less reliable than its Japanese counterparts. BMWs and Mercedes of this era also had their share of costly maintenance and repair concerns. Infiniti G35 was generally considered quite reliable.
Price: When new, the CTS was competitively priced, often offering more features or power for the money than a similarly priced BMW or Mercedes. Used, the CTS offers significant value, typically being much cheaper to acquire than a used 3 Series or C-Class of the same vintage, outside of the CTS-V. Lexus IS and Infiniti G35 also hold their value well but are usually still more expensive than a standard V6 CTS.
Alternatives:
- Better Alternatives for Reliability/Resale: Lexus IS250/350 (2006-2008), Infiniti G35 (2006-2007). These offer similar sport sedan dynamics with generally fewer long-term headaches.
- Similar Alternatives (more expensive): BMW 3 Series (E90, 2006-2007) for driving dynamics, Mercedes-Benz C-Class (W203) for traditional luxury and comfort. These will often cost more to buy and maintain.
Final Verdict: Is the 2006 Cadillac CTS a Good Sedan?
Is it worth buying? Yes, but with caveats. It's definitely a used market purchase. For the standard V6 models, it offers tremendous value for the price. The CTS-V is particularly worth buying for enthusiasts looking for a budget-friendly performance machine with a manual transmission, offering supercar-baiting power for a fraction of the cost.
Conditions for buying: A thorough Pre-Purchase Inspection (PPI) is essential. Look for a vehicle with documented maintenance records. Be prepared to budget for higher maintenance and potential repair costs. The 3.6L V6 offers a good balance, while the CTS-V is for those craving raw power. For the informed buyer willing to perform due diligence, the 2006 Cadillac CTS offers a rewarding and stylish driving experience at a compelling used price point.
