2020 Honda Civic — Known Issues & Recalls

Your 2020 Honda Civic was in a collision at 60 MPH that caused extensive front-end and undercarriage damage, but the driver's and passenger's side airbags did not deploy as expected. After the collision, the vehicle's speed was limited to 40 MPH. The collision center discovered that all airbags had been removed and the wires were cut and twisted together, which fooled the sensors into thinking the airbags were still properly connected. The vehicle was not repaired due to cost concerns.

Your 2020 Honda Civic's passenger seat weight sensor has failed electrically, which means the airbags won't deploy for passengers sitting in that seat since the system can't detect their weight. A Honda dealership confirmed this is a real problem with your vehicle, not caused by an accident. The SRS (airbag system) warning light came on while driving and remains on. Fixing this will likely require replacing the faulty weight sensor under the passenger seat.

Your 2020 Honda Civic was included in a recall (Campaign 24V064000) related to the airbags. You took your vehicle to the dealer for the recall repair, but the dealer informed you that the necessary parts aren't available yet. You feel the manufacturer has taken too long to provide these parts for the repair.

Your 2020 Honda Civic is subject to a safety recall (Campaign 24V064000) involving the airbag system. Your dealer has informed you that the necessary parts are on backorder with no estimated arrival date. You're concerned that the manufacturer has taken too long to make parts available for this recall repair. Your airbags have not failed, but the recall work remains incomplete.

Your car's driver's side airbag deployed after hitting a protruding manhole cover while driving at 10 mph. The impact with the undercarriage triggered the airbag system unexpectedly, even though this wasn't a crash situation. The airbag system may need to be inspected and possibly reset by a technician to ensure it functions properly in actual emergency situations.

Your 2020 Civic Si's clutch failed completely at under 32,000 miles while you were driving on the interstate. The engine was revving excessively (over 6,000 RPM) in all gears, and the car couldn't accelerate normally—you could only reach 50 mph briefly before it slowed to 45 mph or lower, creating a serious safety hazard in traffic. When you pulled over, the car wouldn't shift into first gear at all, leaving you stranded on the highway despite the vehicle being properly maintained with no modifications or rough driving. The clutch assembly will need to be completely replaced.

Your clutch started slipping suddenly even though the clutch disc was only about 30% worn, with no damage to the flywheel or clutch cover—indicating a defect in the clutch cover's holding force rather than normal wear. The owner discovered this after the manufacturer warranty expired at 36,000 miles and wasn't aware Honda had an extended clutch warranty available for this defect. If the car had continued to be driven this way, the clutch would have burned up from the excessive slipping.

Your Civic Si's clutch may start slipping and failing prematurely, often beginning around 5,000-6,000 RPM in higher gears during moderate acceleration. Once slipping begins, complete clutch failure can happen relatively quickly. Honda has a Technical Service Bulletin allowing replacement within 5 years/60K miles, but repair typically costs around $2,000 just for inspection and teardown. Fixing this issue will require clutch replacement, and potentially replacing the dual mass flywheel at the same time for best results.

Your transmission is leaking fluid due to a failed torque converter seal at 86,165 miles, even though you've maintained the car perfectly and driven it conservatively. The leak is slow but significant enough that your car isn't currently drivable. Fixing this will likely require replacing the torque converter and resealing the transmission, which is an expensive repair.

Your car suddenly shut off without warning while driving, causing all dashboard warning lights to illuminate. This happened twice within a year—first in April 2025 and again in February 2026—even though the dealer had recently replaced the secondary fuel pump as a repair. The second shutdown was particularly dangerous because it occurred while another car was backing up near you, putting you at risk of being hit.

Your car's engine shuts down while driving or won't restart after you park it, though it starts fine again after about an hour. A mechanic diagnosed a faulty fuel pump, and there's an active recall for this issue on your model, but your vehicle's VIN wasn't included in it. The dealership says they can't get fuel pumps because they're being held for recall vehicles only. This has happened at least 20 times since August 2025, and you believe your car should be covered by the recall. Fixing this will require replacing the fuel pump, which should be covered under the recall if your VIN is added to it.

Your car has shut down while driving on 6 occasions, and a mechanic diagnosed a faulty fuel pump. There's a known recall for this issue (bulletin #24008 from Feb 25), but Honda says your vehicle's VIN isn't included in the recall even though similar models are affected. You believe your car should be covered since it has the same problem and only 50,000 miles. The repair would involve replacing the fuel pump assembly.

Your car sometimes gets stuck in accessory mode and won't turn off completely. Additionally, your car may start on its own at night while parked and locked, and the alarm may go off unexpectedly. This suggests an electrical system issue that could drain your battery or cause unwanted vehicle activation.

Your car's body control module (BCM) became faulty and caused the ignition to turn on by itself even when the car was off, which startled you and drained the battery and gas unnecessarily. To prevent further damage while troubleshooting, you had to disconnect the battery, which reset several electrical systems. An independent electrical mechanic confirmed and repaired the issue.

Your car's collision mitigation braking system (CMBS) is falsely detecting obstacles and automatically braking hard when the road ahead is completely clear. This has happened 4-5 times in the past year, sometimes requiring you to restart the car to regain control. Because this false braking can happen randomly on busy roads, it poses a serious safety risk to you and your passengers. The fix would likely involve Honda diagnosing the sensor or software that's causing the false collision detection and either recalibrating or replacing the faulty components.

While driving on the highway in rainy conditions, you heard a loud thump and your wheel suddenly turned sideways, forcing you to struggle to keep your car on the road. You didn't hit anything, but the sudden movement suggests a steering or suspension component may have failed or separated. This will likely require a full inspection of your steering and suspension system to identify and replace the damaged part.

Your steering wheel gradually stiffens and then suddenly releases while driving on the highway, and this cycling repeated multiple times during long trips on October 22 and October 25, 2025. No warning lights or messages appeared before or during these incidents. This unpredictable steering behavior creates a safety hazard for you and other drivers on the road. The issue likely requires your Honda dealership to diagnose and repair the power steering system or related steering components.

While driving 55 mph on the highway, you felt your passenger-side wheel suddenly loosen, causing your car to pull sharply to the right. The wheel didn't actually detach, and your car returned to normal driving. No warning lights appeared, and the issue hasn't been diagnosed or repaired. This may be related to a known Honda recall about wheel attachment.

Your air conditioning system has a refrigerant leak in the evaporator assembly, leaving your cabin warm even when the AC is set to the coldest setting. This also reduces your ability to defog windows in humid or rainy conditions, which can affect visibility and safe driving. A Honda dealership confirmed the leak through testing. The fix will require replacing or repairing the evaporator assembly and recharging the refrigerant system.

Your rear windshield cracked on its own while you were sitting in the parked car with the engine off—you even heard a popping sound. There was no impact or accident that caused it. The dealer inspected the vehicle but didn't diagnose or repair the problem. Fixing this will likely require rear windshield replacement.
