Vehicle Highlights

DTS replaced Cadillac's long-lived DeVille for 2006, as a restyled update of the company's largest sedan. Continuing a basic front-wheel-drive design, the DTS had a 4.6-liter V8, four-speed automatic transmission, and self-leveling rear suspension. Dimensions were little changed from the prior DeVille. The new DTS came with a standard 275-horsepower Northstar V8 engine. A Performance Package option raised engine output to 291 horsepower, accompanied by a firmer suspension with auto-adjusting shock absorbers, and 18-inch wheels instead of the usual 17s. With its DTS, Cadillac competed against such premium full-size sedans as the Buick Lucerne, Lexus LS 430, and Lincoln Town Car. Every DTS included antilock braking, traction control, front torso side airbags, and head-protecting curtain side airbags. Also standard were Magnetic Ride Control, a tire-pressure monitor, remote engine start feature, xenon headlights, GM OnStar assistance, and leather upholstery. The in-dash six-CD changer included an MP3 provision. Cadillac claimed the dual-depth front passenger airbags was an industry first. Styling followed Cadillac's traditional cues, including vertical headlights and taillights, and an eggcrate grille. An available front bench seat could increase passenger capacity from five to six. Additional options included an antiskid system, front-rear obstacle detection, navigation system, satellite radio, and cruise control designed to maintain a set following distance. Also available were heated/cooled front seats and a heated steering wheel.

Consumer Guide® Road-Test Evaluation

Both of Cadillac's V8s furnish punchy takeoffs, accelerating to 60 mph in about 7.0 seconds. Midrange power is good, too, for confident merging and passing, though the automatic transmission sometimes hesitates to downshift for passing. Some testers have praised the automatic's quick response; others are troubled by those slow downshifts. Most premium cars have automatic transmissions with more than the Cadillac's four speeds. A Luxury model averaged 23.7 mpg in mostly highway driving, versus 18.7 mpg with more city work. In mostly city driving, a Performance model managed only 14.4 mpg. Cadillac recommends 87-octane, regular-grade fuel. Base suspensions comfortably smother most bumps, but allow some float and wander over large moguls. The firmer Performance setup checks body motions with little comfort penalty, despite 18-inch wheels and lower-profile tires. Steering/handling is no-surprises competent, but compromised by the DTS's size and heft, as well as a large turning circle. In Luxury models, even moderately fast turns induce considerable body lean and nosedive. Grip is modest on the ride-biased base suspension with 17-inch tires. The Performance version with 18-inch tires feels more stable and confident. All models reassure with the available antiskid system and brakes that deliver short, no-drama stops. Expect modest wind noise at any speed, but coarse-surface tire thrum is a bit high by premium-class standards. V8 sounds are audible, but subdued even at full throttle. The engine growls pleasantly while accelerating, especially in the Performance model, but it's toned down otherwise. Redesigned for 2006, the dashboard has clear analog gauges and large, mostly handy minor controls. However, some switch icons are not obvious, and others are too small and/or hard to make out in daylight. Refreshingly simple climate controls are independent of the optional navigation system, which absorbs but doesn't complicate audio functions. Though it isn't daunting, the navigation system does take time to learn. Some test cars have disappointed with minor squeaks and rattles. Workmanship is acceptable otherwise, though most import-brand rivals do better. Overall quality of cabin materials beats Lincoln's, but trails most import-brand rivals. Cadillac's biggest model is among the roomiest and most comfortable big sedans, though the available bench seat may squeeze a middle rider. Front bucket seats seem all-day comfortable. Ample seat/steering-wheel adjustments cater to most any driver, but visibility is a bit restricted to the right rear, directly aft. In the rear, firm support is accompanied by plenty of head and legroom, with sufficient width for a middle adult--though the center backrest section is quite hard. Toe space is tight, too. Entry/exit is easy. Some testers have praised the Luxury II's massage feature; others have declared it annoying. Either way, its activation switch is hard to reach. The DTS trunk swallows four golf bags and more, through a large, bumper-level opening. Interior storage is limited, and the center pass-through opening is too small to be of any real utility.
Value for the Money
In this price range, Cadillac leaves any sporting pretensions to its rear-drive and AWD STS models. The front-drive DTS aims for traditional American luxury-car buyers--and scores with them. Powerful, roomy, and refined, it matches most competitors for standard safety features. Overall, it's a bit more solid and better finished than the earlier DeVille, but otherwise much the same. Curtain side airbags, an important safety feature standard on DTS, were unavailable on DeVille. Base and Luxury I editions are particularly strong Recommended values.

Each vehicle report contains one rating chart for representative model. Consumer Guide® rates in ten key areas: Performance, Fuel Economy, Ride Comfort, Steering and Handling, Interior Noise, Controls and Materials, Driver Room, Passenger Room, Cargo Capacity, and Insurance Costs. These ratings compare the particular vehicle rated to ALL other vehicles, not a vehicle's standing in a particular class. In the ratings table, "1" is the lowest rating and "10" is the highest rating.

Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Check-engine light: The check engine (service engine soon) light may come on if the car idles over 30 minutes requiring reprogramming of the powertrain control module. (2006)

Keyless entry: The remote keyless entry system may not work or may work poorly and/or the tire pressure warning may come on due to a malfunction of the receiver and antenna. (2006-07)

Paint/body: The paint on the aluminum hood blisters requiring refinishing. (2006)

Radiator: The upper radiator hose may leak due to a manufacturing problem. (2006)

This chart details a range of prices in year-by-year listings for vehicles in three condition levels:
Good: a clean low-mileage, solid-running vehicle that needs little or no repair.
Average: a car with normal miles on the odometer, perhaps a few scrapes or dings; engine might need a minor repair or two, but runs acceptably well.
Poor: might have potentially dangerous problems with the engine and/or body, or abnormally high mileage; definitely in need of mechanical attention. Valuations reflect wholesale prices paid by dealers at auction, and retail prices on used-car lots. Each range covers all trim levels and engine types for a vehicle with a typical amount of equipment--usually an automatic transmission, air conditioning, stereo, etc. Fully loaded vehicles may cost more. Average mileage is 12,000 miles per year. Keep in mind that these are guidelines only. Actual selling prices vary- especially from region to region.

NHTSA Crash-Test Results

Test 2006 DTS
Front Impact, Driver 5
Front Impact, Passenger 4

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Sideimpact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.

NHTSA Recall History

2006: Power steering hose connectors may have been inadequately crimped, which could result in fluid leakage and loss of power-steering assist.
2006-08 DTS equipped with a heated wiper washer fluid system: A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor, or cause smoke, increasing the risk of a fire. Dealers will install a wire harness with an in-line fuse free of charge.
