Acura SLX: The Rebadged Trooper - A Comprehensive Guide
The Acura SLX, produced from 1996 to 1999, holds a unique and often misunderstood place in Acura's history. Essentially a rebadged and slightly more luxurious Isuzu Trooper, the SLX represented Acura's foray into the burgeoning SUV market. While it offered a comfortable ride and genuine off-road capability, its reliance on Isuzu engineering and a few controversial issues ultimately led to its short production run. This guide provides a comprehensive look at the Acura SLX, helping prospective buyers understand its strengths, weaknesses, and overall value proposition.
Generations
There is only one generation of the Acura SLX, spanning the years 1996-1999. However, minor revisions were made during its run.
- 1996-1997: Initial launch of the Acura SLX. Featured a 3.2-liter V6 engine. Interior and exterior styling were slightly altered from the Isuzu Trooper, including a unique Acura grille and badging, and upgraded interior materials.
- 1998-1999: Introduction of a larger, more powerful 3.5-liter V6 engine. Front suspension was also revised to address rollover concerns (more details in the Reliability section). Minor cosmetic updates were made to the interior.
Reliability & Common Issues
The Acura SLX's reliability is largely tied to the Isuzu Trooper it's based on. While generally robust, several key issues need careful consideration.
Engine (3.2L and 3.5L V6)
- Oil Leaks: Both the 3.2L and 3.5L V6 engines are prone to oil leaks, particularly from the valve cover gaskets, rear main seal, and oil pan gasket. Regular inspection and prompt repair are crucial.
- Timing Belt: These engines use a timing belt that requires replacement every 60,000-75,000 miles. Failure to do so can result in catastrophic engine damage. Verify the replacement history before purchasing.
- Oil Consumption: The 3.5L engine, in particular, can exhibit oil consumption as it ages. Monitor oil levels regularly.
Transmission (Automatic)
- Slipping or Erratic Shifting: The automatic transmission can be prone to slipping or erratic shifting, especially in higher mileage vehicles. This can be due to worn clutches or a failing torque converter. Regular transmission fluid changes are essential for longevity.
- Torque Converter Issues: Torque converter failure can be costly to repair. Listen for unusual noises or vibrations during acceleration.
Four-Wheel Drive System
- Vacuum Leaks: The 4WD system relies on vacuum to engage. Vacuum leaks can prevent the system from engaging properly. Inspect vacuum lines and connections.
- Transfer Case Issues: While generally reliable, the transfer case can experience wear and tear, particularly if not properly maintained. Listen for unusual noises or vibrations when engaging 4WD.
Suspension and Steering
- Ball Joints and Tie Rod Ends: These components are subject to wear, especially with off-road use. Regular inspection and replacement are necessary to maintain proper handling.
- Rear Leaf Springs: The rear leaf springs can sag over time, affecting ride height and handling.
Rollover Risk (Pre-1998 Models)
- Consumer Reports Controversy: In 1996, Consumer Reports famously rated the Isuzu Trooper (and by extension, the Acura SLX) as "Not Acceptable" due to concerns about its rollover risk in their emergency handling tests. While the controversy was complex and debated, it undeniably damaged the SLX's reputation.
- 1998 Revision: Acura and Isuzu addressed these concerns in 1998 by widening the track and revising the front suspension geometry to improve stability. 1998 and 1999 models are considered significantly safer than earlier years.
Rust
- Frame and Body: Rust can be a significant issue, particularly in areas with road salt. Thoroughly inspect the frame, undercarriage, and body panels for rust before purchasing. Pay close attention to areas around the wheel wells and rocker panels.
Driving Experience
The Acura SLX offers a mixed driving experience, reflecting its dual nature as a comfortable daily driver and a capable off-roader.
Pros:
- Comfortable Ride: The SLX provides a relatively smooth and comfortable ride on paved roads, especially compared to more truck-like SUVs of its era.
- Genuine Off-Road Capability: With its solid axles, four-wheel drive system, and ample ground clearance, the SLX is a very capable off-road vehicle.
- Spacious Interior: The interior is spacious and offers comfortable seating for up to five passengers.
- Luxurious Features (for its time): Compared to the Trooper, the SLX offered upgraded interior materials, standard leather seating in later years, and premium audio options.
Cons:
- Fuel Economy: Fuel economy is poor, even by the standards of older SUVs. Expect around 14-16 MPG combined.
- Handling: Handling can be somewhat vague and imprecise, especially compared to modern SUVs. Body roll is noticeable in corners.
- Rollover Concerns (Pre-1998 Models): The pre-1998 models have a higher center of gravity and are more prone to rollover in emergency maneuvers.
- Parts Availability: While many parts are still available, some specific SLX-only components can be difficult to find.
Buying Advice
If you're considering purchasing an Acura SLX, here's some key advice:
- Year Matters: The 1998 and 1999 models are significantly preferred due to the larger engine and improved suspension geometry that addressed rollover concerns.
- Pre-Purchase Inspection: A thorough pre-purchase inspection by a qualified mechanic is essential. Pay close attention to the engine, transmission, 4WD system, suspension, and frame.
- Check for Rust: Rust is a major concern, so thoroughly inspect the vehicle for any signs of corrosion.
- Verify Maintenance Records: Look for vehicles with detailed maintenance records, particularly those showing regular oil changes, timing belt replacement, and transmission fluid changes.
- Negotiate Accordingly: Be realistic about the vehicle's age and potential maintenance costs. Use any identified issues as leverage to negotiate a lower price.
- Consider the Trooper: Don't automatically dismiss the Isuzu Trooper. It's mechanically identical to the SLX and often available at a lower price. You can potentially add some of the SLX's luxury touches yourself.
- Be Realistic About its Age: This is a vehicle that's over 20 years old. Be prepared for potential maintenance and repairs, and factor that into your budget.
The Acura SLX can be a rewarding vehicle for the right buyer. Its combination of comfort, off-road capability, and classic SUV styling makes it appealing. However, it's essential to be aware of its potential issues and to thoroughly inspect any prospective purchase. With careful research and due diligence, you can find a well-maintained SLX that provides years of enjoyment.
