The picture

Is the BMW 840I or Honda Accord more reliable?

A plain-English read on what the NHTSA record says about living with each vehicle.

BMW 840I

The BMW 840I is a low-volume luxury coupe with no owner complaints filed over seven years, so there is little real-world failure pattern to study. Its 19 recalls are the main documented concern, covering the driveshaft, starter, battery, and rear camera. In ownership terms, that means fewer reported day-to-day problems but a higher chance of open recall work. A buyer should treat it as a car where recall status matters more than complaint history.

Honda Accord

The Honda Accord is a high-volume vehicle with 4,524 complaints over ten years, about 452 per year, so there is a large and active record of owner-reported issues. The most common areas are the engine, electrical system, forward collision avoidance, and fuel system. Reported symptoms include sudden warnings, loss of speed, rough hybrid transitions, and steering or braking failure. It also has 162 crash-related complaints, 146 injuries, and 3 deaths in the data, which makes pre-purchase inspection especially important.

What actually goes wrong

The problems owners report

The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

BMW 840I

No component data available.

What these mean
Power train driveline driveshaft

The BMW 840I has recalls for the driveshaft, a part that sends power to the wheels. A failing driveshaft can cause vibration, clunking, or loss of drive, so a buyer should confirm the recall was completed.

Electrical system starter assembly

There is a recall for the starter assembly, which is what turns the engine over. A bad starter can leave you stranded or cause repeated no-start conditions, so check for recall service records.

Electrical system 12V/24V/48V battery

A battery-system recall is listed, and modern luxury cars rely heavily on proper voltage. Battery faults can trigger warning lights, weak starts, or electronic glitches, so have the battery and charging system tested.

Back over prevention sensing camera

The rear camera sensing system is under recall, which matters for parking and low-speed maneuvering. If the camera or sensors fail, you lose a driver aid that many owners depend on daily.

  3. 03FORWARD COLLISION AVOIDANCE837
  4. 04UNKNOWN OR OTHER746
  5. 05FUEL/PROPULSION SYSTEM602
What these mean
Engine

Owners report alarms for brake, hill descent, ABS, and critical failure, followed by the vehicle losing speed. Others describe rattling noises while accelerating and rough transitions between EV and gas mode. These are not minor annoyances because loss of speed at highway speeds is a serious drivability concern.

Electrical system

Complaints describe electronic power steering and braking failing and locking up at highway speeds, plus a tire failure after a TPMS warning was supposedly repaired. Electrical faults can affect steering, braking, and warning systems at once, so a buyer should test all driver aids and check for open recalls.

Forward collision avoidance

Owners report the system failing to resolve a threat, and one complaint describes adaptive cruise control suddenly behaving unexpectedly at 70 mph. These are safety-related driver aids, so any warning light or inconsistent behavior should be treated as a reason to walk away or demand repair.

Fuel/propulsion system

The fuel system is a top complaint area, and there is a recall for the gasoline fuel pump delivery. A failing fuel pump can cause stalling or loss of power, and owners also report a persistent rotten-egg or sulfur odor. Both point to fuel-system issues that need a thorough inspection.

Buyer analysis

BMW 840I or Honda Accord: which should you buy?

The BMW 840I has 0 complaints per year over 7 years, while the Honda Accord has about 452 complaints per year over 10 years. In practice, the BMW has far fewer reported owner problems, but it still has 19 recalls to track. The Accord's much larger complaint record means a used buyer should expect more reported issues and should inspect the engine, electrical, and safety systems closely.

Recommendation. If you want the lowest reported complaint rate and can manage recall paperwork, the BMW 840I is the better fit. If you need a mainstream vehicle with widely available parts and service, the Honda Accord may be easier to own, but only after a thorough inspection and recall check. In either case, do not skip a pre-purchase inspection and a VIN-based recall lookup.

Key differences

  • The BMW 840I has 0 complaints over 7 years, while the Honda Accord has 4,524 complaints over 10 years, about 452 per year.
  • The BMW's documented issues are recall subjects like driveshaft, starter, battery, and rear camera, with no owner complaint text on record.
  • The Honda Accord has real owner-reported symptoms including loss of speed, rough hybrid transitions, steering and braking failure, and forward collision avoidance problems.
  • The Honda Accord data includes 162 crash-related complaints, 146 injuries, and 3 deaths, while the BMW 840I shows 0 in those categories.
Watch on BMW 840I
  • Check for any vibration, clunking, or unusual noise from underneath that could point to the recalled driveshaft, and confirm the recall was performed.
  • Test the starter and battery system, including cold starts and warning lights, because both are listed recall areas on this model.
Watch on Honda Accord
  • Watch for warning messages about brakes, hill descent, ABS, or critical failure, and any loss of speed or rough transition between EV and gas mode.
  • Test the forward collision avoidance and adaptive cruise control, and check for a rotten-egg or sulfur odor that could indicate a fuel-system issue.

Before you buy

  • Run the VIN through NHTSA to see which recalls are open or completed on the specific BMW 840I or Honda Accord you are considering.
  • For the BMW 840I, ask for proof that the driveshaft, starter, battery, and rear camera recalls were addressed.
  • For the Honda Accord, scan for stored codes and test the engine, hybrid transition, electronic power steering, braking, and forward collision avoidance systems.
  • Take a test drive that includes highway speeds, because several Accord complaints describe problems appearing at highway speed.
  • Have an independent mechanic inspect the vehicle, including the fuel system and battery/charging system, before you buy.
