Most Common 2015 Honda Accord Problems Explained
The 2015 Accord is a solid vehicle, but its track record reveals a few repeating themes. These issues tend to pop up as the car accumulates miles, typically after the 60,000-mile mark. Being aware of them is the first step to proactive ownership.
Here’s a quick list of the problems we’ll cover in detail:
* Excessive Vibration During Braking
* Battery Drain and Electrical Gremlins
* Uncomfortable Shuddering from the Transmission
* Power Steering Whine and Stiffness
* Premature Brake Wear and Noisy Rotors
* Faulty Fuel Injectors Causing Misfires
* Air Conditioning Blowing Warm Air
* Squeaks and Rattles in the Cabin
1. Excessive Vibration When Braking (Warped Rotors)
A common complaint is a strong steering wheel vibration when applying the brakes, especially at higher speeds. This is almost always caused by warped front brake rotors. The vibration can feel concerning, but the fix is usually straightforward.
The rotors warp due to uneven heat distribution. This can happen from aggressive driving, but a more frequent cause on the Accord is sticking brake caliper slide pins. The pins don’t retract properly, causing the brake pad to drag and overheat the rotor consistently.
How to Diagnose and Fix It:
1. Diagnosis: Drive at a safe, moderate speed (e.g., 45-50 mph) on a clear road. Gently apply the brakes. If you feel a pulsation in the steering wheel, your front rotors are likely warped. A pulsation in the seat or floorboard points to rear rotors.
2. Inspect Caliper Slide Pins: When replacing the rotors and pads, this is crucial. Remove the caliper slide pins, clean them thoroughly, and lubricate them with high-temperature silicone brake grease.
3. Replace or Resurface: Severely warped rotors need replacement. If within thickness specifications, they can sometimes be resurfaced (“turned”) on a brake lathe for a smoother finish. Always replace brake pads in sets (both fronts or both rears).
2. Battery Drain and Electrical Issues
Many owners report a dead battery after the car sits for a short time, like a day or two. This parasitic drain is frustrating. The 2015 Accord’s electrical system can have a few culprits.
The most common source is the Bluetooth HandsFreeLink (HFL) module. When it fails, it doesn’t go to sleep properly and continuously draws power from the battery. Other possibilites include aftermarket accessories (dash cams, alarms) or a weak alternator not fully recharging the battery.
Steps to Track Down the Drain:
1. Rule Out the Battery: First, have your battery load-tested. An old, weak battery can simmulate a drain issue.
2. Check for Recall: Honda issued a warranty extension (Technical Service Bulletin 15-091) for the HFL module in certain 2013-2015 Accords. Contact a dealer with your VIN to see if your car is covered.
3. Parasitic Draw Test: This requires a multimeter. With the car closed and locked (wait 45+ minutes for modules to sleep), disconnect the negative battery terminal. Connect the multimeter in series between the terminal and battery post. A draw over 50 milliamps (0.05 amps) is excessive. Pull fuses one by one to see which circuit causes the draw to drop.
3. Transmission Shudder or Jerking (CVT Issues)
The Continuously Variable Transmission (CVT) in the 4-cylinder models can develop a noticeable shudder or jerking sensation, usually between 20-40 mph under light acceleration. It feels like driving over rumble strips.
This is often related to the transmission fluid breaking down or a faulty torque converter. The CVT fluid is critical for proper operation and pressure. Honda has updated the recommended fluid type and service intervals for this very reason.
What You Can Do:
* Fluid Change: The single most effective maintenance for this issue is a complete CVT fluid drain and refill using only genuine Honda HCF-2 fluid. Do not just do a drain-and-fill; consider a triple fluid exchange for a more complete change if the shudder is present.
* Software Update: In some cases, a dealership can perform a powertrain control module (PCM) software update that adjusts transmission programming.
* Torque Converter: If fluid changes don’t resolve the shudder, the torque converter may be failing internally and require replacement—a more significant repair.
4. Power Steering Whine or Stiff Steering
You might hear a whining noise from the engine bay, especially when turning the wheel at low speeds or while parked. The steering may also feel heavier than it should. This points to the electric power steering system.
The 2015 Accord uses an electric power steering (EPS) system, not a hydraulic one. The whine is typically normal operation of the EPS motor. However, if it becomes excessively loud or steering feels stiff, the issue could be with the EPS assist motor, the sensor, or a related control unit.
Diagnosis and Solutions:
1. Check for Codes: Any problem with the EPS system will almost always illuminate the power steering warning light on the dash and store a diagnostic trouble code. A basic OBD-II scanner may not read these; a more advanced scanner or dealer tool is needed.
2. Inspect the Rack: Have a mechanic check the steering rack for physical damage or loose connections.
3. Professional Diagnosis: Due to the complexity and safety implications, diagnosis of a stiff steering complaint is best left to a professional technician familiar with Honda EPS systems.
5. Premature Brake Wear and Squealing
Some owners find themselves replacing brake pads more often than expected, sometimes with accompanying squealing noises. This ties back to the sticking caliper slide pins mentioned earlier, but also to the quality of brake components.
The factory brake pads can be somewhat dusty and wear quicker than aftermarket ceramic options. Additionally, rust buildup on the hub where the rotor mounts can cause the rotor to sit unevenly, leading to premature pad wear and vibration.
To Extend Brake Life:
* Annual Caliper Service: Each year, during tire rotation or brake inspection, clean and re-lube the caliper slide pins.
* Use Quality Parts: When replacing, consider reputable aftermarket ceramic pads and coated rotors. The coatings resist rust and can reduce noise.
* Proper Installation: Always clean the hub surface perfectly smooth before installing a new rotor to ensure it sits flush.
6. Faulty Fuel Injectors Causing Misfires
A rough idle, lack of power, check engine light, and misfire codes (like P0300, P0301, etc.) are signs of a fuel injector problem. The direct injection (DI) fuel injectors in the Earth Dreams engines can become clogged or fail.
Carbon buildup on the injector tips or internal valve failure can disrupt the precise fuel spray pattern. This leads to incomplete combustion in that cylinder. The problem may be intermittent at first.
How to Address Fuel Injector Problems:
1. Read Codes: Use a scan tool to confirm which cylinder is misfiring (e.g., P0301 is cylinder 1).
2. Swap Test: A mechanic can swap the suspect injector with one from another cylinder. If the misfire code follows the injector, you’ve found the culprit.
3. Replacement: Replace the faulty injector. It’s often recommended to replace the entire set if one fails, especially at higher mileages, and to also clean the intake valves of carbon deposits while the intake manifold is off.
7. Air Conditioning Blowing Warm Air
A sudden loss of cold air is a frequent issue. The most common cause for the 2015 Accord is a failure of the air conditioning condenser. Road debris can puncture it, or it can develop leaks at its seams.
The condenser is mounted in front of the radiator. Its design makes it vulnerable. A leak here allows refrigerant to escape, rendering the AC system inoperative. You may here the compressor clutch clicking on and off rapidly.
Fixing the AC System:
1. Leak Test: A professional will use UV dye and a leak detector to find the source. The condenser is the prime suspect.
2. Condenser Replacement: Replacing the condenser is the fix. Honda has released revised part designs that may be more durable. Ensure the receiver/drier is also replaced and the system is properly vacuumed and recharged.
3. Check the Compressor: If the system was run low on refrigerant for too long, the compressor may have sustained damage and need replacement as well.
8. Interior Squeaks and Rattles
As the car ages, interior trim pieces can loosen and create annoying noises. Common locations include the dashboard, center console, door panels, and the area around the sunroof.
These are not mechanical failures but can significantly impact driving enjoyment. The noises are caused by plastic clips loosening, trim pieces rubbing against each other, or loose components.
Simple Fixes for a Quieter Cabin:
* Identify the Source: Have a passenger help locate the exact area while you drive. Press on different panels to see if the noise stops.
* Felt Tape is Your Friend: Wherever two trim pieces meet, applying thin adhesive-backed felt tape can cushion and silence the contact.
* Check Loose Items: Sometimes the noise is from items in the glove box, center console, or door pockets. Rule these out first.
* Sunroof Rattle: Often fixed by cleaning the sunroof seal and adjusting the glass height or tightening guide bolts slightly.
