2014 Acura Rlx Recalls, Issues & Maintenance

The 2014 Acura Rlx carries 5 open NHTSA recalls — most recently covering crash imminent braking and seat belts. Owners report 4 recurring issue clusters, led by “Rear-wheel steering actuator failure and fishtailing.” Acura's Maintenance Minder calculates oil life from real engine conditions and shows service codes instead of fixed mileages — code A or B (oil / oil + inspection) plus sub-codes for items like tire rotation (1), air filters (2), or transmission fluid (3). Follow the codes, not the calendar. One interval you should never stretch: most Acura 3.5L V6 engines (MDX, TL) use a timing belt with a roughly 105,000-mile / 7-year replacement — a snapped belt on this interference engine means bent valves. SH-AWD models add a rear-differential fluid service that's essential for the torque-vectoring unit.

FORWARD COLLISION AVOIDANCE: CRASH IMMINENT BRAKING

Campaign #15V301000 · May 20, 2015

Issue: Honda (American Honda Motor Co.) is recalling certain model year 2014-2015 Acura MDX 2WD and AWD, RLX and 2014 Acura RLX Hybrid vehicles. In certain driving conditions, the Collision Mitigation Braking System (CMBS) may incorrectly interpret certain roadside objects such as metal fences or metal guardrails as obstacles and unexpectedly apply the brakes.

Risk: If the CMBS unexpectedly applies emergency braking force while driving, there is an increased risk of a crash.

Fix: Honda will notify owners, and dealers will update the CMBS software, free of charge. The recall began on July 6, 2015. Owners may contact Acura customer service at 1-800-382-2238. Honda's numbers for this recall is JQ4, JQ5 and JQ6.

SEAT BELTS

Campaign #14V639000 · Oct 10, 2014

Issue: American Honda Motor Company (Honda) is recalling certain model year 2014-2015 Acura MDX vehicles manufactured April 23, 2013, to August 25, 2014, and 2014 Acura RLX vehicles manufactured November 5, 2012, to November 25, 2013. In the affected vehicles, the driver and front passenger seat belt may not extend or retract in low temperatures.

Risk: A seatbelt that does not function increases the risk of injury in a crash.

Fix: Honda has notified owners, and dealers will replace the driver and front passenger seat belts, free of charge. The recall began in November 2014. Owners may contact Acura customer service at 1-800-382-2238. Honda's number for this recall is JK7 for the MKX, and JK8 for the RLX.

EXTERIOR LIGHTING:HEADLIGHTS

Campaign #14V792000 · Dec 16, 2014

Issue: American Honda Motor Co. (Honda) is recalling certain model year 2014 Acura RLX vehicles manufactured November 22, 2012, to January 30, 2014, 2015 Acura RLX vehicles manufactured June 4, 2014, to November 18, 2014, and 2014 Acura RLX Hybrid vehicles manufactured November 5, 2013, to July 25, 2014. An aluminum film applied to the inner reflector of the headlight may experience adhesion issues causing the film to delaminate. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, reflective devices, and associated equipment."

Risk: Delamination of the aluminum film may diminish output of the headlight, increasing the risk of a vehicle crash.

Fix: Honda will notify owners, and dealers will replace both of the headlights, free of charge. The recall began February 2, 2015. Owners may contact Honda customer service at 1-310-783-2000. Honda's number for this recall is JN2.

SUSPENSION:REAR

Campaign #13V622000 · Dec 16, 2013

Issue: American Honda Motor Company (Honda) is recalling certain model year 2014 Acura RLX vehicles manufactured August 7, 2012, through November 5, 2013. The bolts that attach the rear lower control arms to the sub-frame of the vehicle may have loosened during transport to dealerships.

Risk: Loose rear lower control arm bolts may reduce steering ability, increasing the risk of a crash.

Fix: Honda will notify owners, and dealers will replace the rear suspension lower control arm bolts, free of charge. The recall is expected to begin in early January 2014. Customers may contact Honda at 1-800-999-1009. Honda's number for this recall is JD0.

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

Campaign #23V858000 · Dec 18, 2023

Essential maintenance

Critical for safety and preventing major damage

Oil & Filter (Maintenance Minder A/B)

Every 8,000 mi

Change when the Maintenance Minder reaches 15% oil life or shows code A/B — typically every 7,500-10,000 miles with 0W-20 synthetic. Short-trip city driving triggers the code sooner; that's the algorithm doing its job.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Timing Belt (3.5L V6 — MDX, TL)

Every 105,000 mi

J-series V6: replace the timing belt around 105,000 miles or 7 years (Maintenance Minder sub-code 4). It's an interference engine — a failed belt destroys valves. Replace the water pump and tensioner in the same job. (2022+ MDX 3.5L remains belt-driven; the Integra's turbo four is chain-driven.)

Estimated cost — typical U.S. ranges

Dealer

~$935–$1175

Shop

~$655–$825

DIY

Pro only

On interference engines, a snapped belt destroys valves. Worth doing on schedule. Bundle water pump + tensioner — labor is already there.

Tire Rotation (Sub-code 1)

Every 7,500 mi

Rotate when sub-code 1 appears — roughly every 7,500 miles. SH-AWD models: keep tread depths matched across all four corners.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 10,000 mi

Inspect pads, rotors, and fluid level with every A/B service. Type S models with Brembo front calipers: pads wear faster and cost more — budget ahead.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 30,000 mi

Replace every 3 years regardless of mileage — Honda/Acura schedules this on time because the fluid absorbs moisture.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Transmission Fluid (Sub-code 3)

Every 30,000 mi

Replace ATF when sub-code 3 appears — commonly every 30,000-60,000 miles depending on duty. Use Honda/Acura ATF only (DW-1, or the 10-speed's specified fluid); aftermarket 'universal' ATF causes shudder in these gearboxes.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

SH-AWD Rear Differential Fluid

Every 30,000 mi

SH-AWD (MDX, TLX, RDX): replace the rear differential fluid roughly every 30,000 miles (sub-code 6) — the torque-vectoring clutch packs run in this fluid, and whining or binding in tight turns is the classic overdue symptom.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Spark Plugs (Sub-code 4)

Every 100,000 mi

Iridium plugs around 100,000 miles on most models. Turbocharged Integra/ADX engines: check the manual — forced induction typically shortens the interval.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Air Filter (Sub-code 2)

Every 30,000 mi

Replace with sub-code 2, roughly every 30,000 miles — sooner in dusty conditions.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter (Sub-code 2)

Every 30,000 mi

Replace with sub-code 2 alongside the engine air filter. Behind the glovebox — an easy DIY on most Acuras.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Coolant Replacement (Sub-code 5)

Every 100,000 mi

Honda/Acura Type 2 coolant: first change around 10 years / 100,000 miles, then every 5 years / 50,000. Use the blue Type 2 coolant only.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Typical U.S. ranges. Actual quotes vary by shop, parts choice, and vehicle condition.

How we estimate: Dealer = OEM parts × 1.4 + labor × $165/hr. Shop = parts + labor × $115/hr. DIY = parts only.
