2007 Acura
RLSedan
Sedan
The 2007 Acura RL is Acura's flagship full-size luxury sedan, riding on Honda's flagship platform with a 3.5L V6 and their Super Handling All-Wheel Drive (SH-AWD) system standard across the lineup. It positions itself as a driver-focused alternative to German sedans, offering a composed ride, strong V6 performance, and a well-appointed cabin without the wallet-punishing complexity of a BMW or Mercedes-Benz. By 2007 the RL was mid-cycle, meaning most early bugs had been sorted. It came loaded with features that were genuinely premium for the era: voice-activated navigation, a Bose audio system, heated and cooled seats, and a hands-free phone system. Tech content has aged, but the mechanicals remain sound on well-maintained examples. For a Lake Geneva buyer, the SH-AWD system is a genuine asset in Wisconsin winters — it actively torque-vectors power between rear wheels for better handling, not just traction. Running costs are moderate for the class, but premium fuel, dealer-grade parts, and a complex AWD system mean this is not a bargain-bin luxury car to own.

Known for
- SH-AWD — torque-vectoring AWD that improves both traction and cornering
- Smooth, refined 3.5L V6 with strong mid-range power
- Quiet, well-insulated cabin with extensive standard luxury features
- Long-term mechanical durability when properly maintained
- Conservative, understated styling relative to European rivals
Best for
- Buyers who want German-competitor features at a lower used price
- Wisconsin drivers who value real AWD in a luxury sedan
- High-mileage commuters who maintain their vehicles diligently
- Those who prefer Honda/Acura reliability over European complexity
Watch for
- VCM oil consumption and carbon buildup if maintenance was deferred
- SH-AWD rear differential requires its own dedicated fluid — often skipped
- Premium fuel required; budget accordingly
- Technology (navigation maps, Bluetooth) is dated and not easily updated
- Timing belt — not a chain — must be replaced on schedule

Maintenance schedule
- 1 Every 105,000 miles or 7 years, whichever comes first Timing belt & water pump replacement
This is a non-negotiable on the 3.5L V6 — it's an interference engine. A snapped belt destroys the valvetrain. Always replace the water pump, tensioner, and idler at the same time since the labor is already done.
- 2 Every 30,000 miles SH-AWD rear differential fluid change
The rear differential uses a specific Dual-Pump Fluid II. Using the wrong fluid or skipping this service causes vibration and eventual differential failure — a $1,500–$2,800 repair. This is the most skipped service on used RLs.
- 3 Every 5,000 miles or 6 months Engine oil change with 5W-20 full synthetic
The VTC system is oil-pressure dependent. Dirty or low oil accelerates VTC actuator wear and can trigger cam timing codes. Use full synthetic and don't stretch intervals on this engine.
- 4 Every 30,000 miles or when cam timing codes appear VTC oil screen cleaning / inspection
A small screen behind the VTC solenoids collects sludge and restricts oil flow to the variable valve timing system. Cleaning it is inexpensive; ignoring it leads to actuator failure.
- 5 Every 30,000 miles for severe duty; 60,000 miles normal Transmission fluid change (ATF DW-1)
The 5-speed automatic is durable but sensitive to old fluid. Use Honda/Acura ATF DW-1 or a verified compatible fluid — generic ATF can cause shift quality issues.
- 6 Every 90,000 miles Spark plug replacement (iridium)
Factory iridium plugs have a long service life. Replacing them on schedule keeps ignition efficient and prevents the frustration of broken plugs from being left too long.
- 7 Every 3 years regardless of mileage Brake fluid flush
Honda/Acura specifies a 3-year brake fluid interval. In Wisconsin's humid climate, moisture absorption is real and degrades braking performance. The SH-AWD system's rear actuators are also fluid-sensitive.
- 8 Every fall, before Wisconsin winter Battery load test and terminal cleaning
The RL's electronics — SH-AWD control module, navigation, memory seats — draw significant parasitic loads. A weak battery causes a cascade of gremlins in cold weather. Test and replace proactively if 4+ years old.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$900 – $1,800
Fuel
Premium fuel required. At current Wisconsin average prices for premium and ~15,000 miles/year, budget approximately $2,400–$2,800/year.
Insurance
Expect $1,200–$1,800/year for a driver with a clean record. The RL's luxury class and all-wheel-drive complexity push rates slightly above a comparable mid-size sedan.
The RL is one of the more affordable ways to own a full-size AWD luxury sedan. Parts and labor run cheaper than European competitors at an independent shop, and the Honda-based drivetrain is unlikely to surprise you with catastrophic failures. The big cost risks are deferred maintenance — especially the timing belt and SH-AWD differential fluid. A diligent owner should expect $900–$1,800/year in routine maintenance, with larger but infrequent expenses (timing belt service ~$800, tires ~$800–$1,200/set) every few years.
Seasonal care
Lake Geneva, WI Winter
- Test the battery every fall — the SH-AWD module and the RL's heavy electronics load will expose a weak battery fast in sub-zero temps. Replace any battery over 4 years old proactively.
- Switch to a winter washer fluid rated to at least -30°F. The RL's long hood and flat windshield collect road spray quickly on Wisconsin highways.
- Inspect and replace wiper blades before first snow. Consider winter-specific beam blades for better ice clearing.
- Check SH-AWD operation before the season. If you feel rear vibration or shudder on low-speed turns, the differential fluid may be due. This system is your winter safety net — don't ignore it.
- Use 5W-20 full synthetic year-round — it's already the correct spec and flows well in cold starts. Avoid switching weights seasonally.
- Rinse the undercarriage regularly through winter. Wisconsin road salt attacks the subframe, brake lines, and the SH-AWD rear drive unit mounting points on these 18+ year-old cars.
Summer
- Check tire pressure monthly — the RL's 17-in tires lose roughly 1 PSI for every 10°F drop from summer to spring. High pressure from heat soak can reduce contact patch in warm months.
- Service the A/C system if cooling seems weak. The RL's cabin is large and the system works hard in July heat; a refrigerant check and cabin air filter swap are cheap preventive measures.
- Inspect coolant concentration and condition. The 3.5L runs warm in traffic; a 50/50 mix of Honda-compatible coolant protects to the upper end of Wisconsin summer heat.
- Check brake pads and rotors after winter — salt and grit accelerate pad wear. Summer is the right time to address brake service before fall inspection season.
