The 2000 Honda Insight is Honda's first-generation hybrid with a manually-shifted CVT or 5-speed that's mechanically simple but plagued by IMA battery degradation, transmission cooler leaks, and surprisingly frequent internal engine damage from lean-run conditions and connecting rod bearing failures.
IMA Battery Pack Failure
Common · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: IMA light illuminated, Check engine light with P1447/P1449 codes, Loss of auto-stop function, Reduced fuel economy by 5-10 mpg, Battery recalibration messages on cluster
Fix: Replace or rebuild NiMH battery pack (20 modules). Grid charging or individual module replacement can extend life temporarily. Labor is 3-4 hours for pack swap, programming required. Rebuilds take 6-8 hours if done in-house.
Estimated cost: $1,500-3,500
Connecting Rod Bearing and Crankshaft Failure
Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Loud knocking from lower engine on cold start, Metallic rattle that worsens under load, Oil pressure warning light, Metal shavings in oil filter, Sudden catastrophic failure with no prior noise in some cases
Fix: Requires full teardown, crankshaft grinding or replacement, new bearings, typically pistons and rings while you're in there. The 1.0L 3-cylinder runs lean and hot. If caught early, bearing replacement is 12-15 hours. Full rebuild or short block swap is 18-22 hours.
Estimated cost: $3,000-6,500
CVT Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: ATF puddles under front of vehicle, Low transmission fluid warnings, Burnt smell from underhood, Erratic CVT behavior or slipping, Visible ATF seepage at cooler line junctions
Fix: Steel lines corrode where they meet the cooler and transmission housing. Requires replacement of lines and often the cooler itself. Labor is 2-3 hours. Neglecting this leads to CVT overheat and belt failure.
Estimated cost: $400-900
Head Gasket Failure (Both Cylinders)
Occasional · high severity
Typical onset: 140,000-200,000 mi
Symptoms: White smoke from exhaust on startup, Coolant loss with no visible leaks, Overheating under load, Rough idle and misfires, Oil contamination in coolant reservoir or vice versa
Fix: Three-cylinder aluminum head prone to warping. Requires head removal, resurfacing, new gasket set. Labor is 8-10 hours. Often done alongside timing belt service. Check for block deck warping as well.
Estimated cost: $1,800-2,800
Electric Power Steering (EPS) Column Failure
Occasional · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: EPS warning light, Heavy steering at low speeds, Intermittent loss of power assist, Grinding or clicking noise from column when turning, Complete loss of assist in worst cases
Fix: Motor or control module inside steering column fails. Honda issued TSB but no recall. Replacement column is typical fix: 2-3 hours labor. Remanufactured units available but failure rate is notable.
Estimated cost: $800-1,400
Fuel Filter Clogging and Fuel Pump Weak Performance
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Hesitation under acceleration, Difficulty starting when hot, Lean codes (P0171), Stumbling at highway speeds, Stalling after long idle periods
Fix: In-tank filter clogs from sediment; pump strainer also gets restricted. Fuel pump assembly replacement is safest long-term fix: 2 hours labor. Filter alone is not separately serviceable without pump access.
Estimated cost: $400-700
Owner tips
Change CVT fluid every 30,000 miles with Honda genuine ATF-Z1 only—aftermarket fluids kill the belt
Monitor IMA battery state-of-charge via scangauge or Torque app; proactive conditioning or grid charging around 120k can delay pack replacement
Use 0W-20 synthetic and change every 5,000 miles maximum due to lean combustion putting stress on bearings
Check transmission cooler lines annually for corrosion starting at 70k miles—catching leaks early saves the CVT
Original headlights fog badly—aftermarket housings or restoration mandatory for night safety
Buy only if IMA battery and CVT have been recently serviced and you can confirm no rod knock—engine internals are the Achilles heel, but a solid example with records is a 50+ mpg unicorn.

Fitment notes: Compact 51R battery due to limited engine bay space in hybrid configuration; IMA battery system is separate 144V NiMH pack

Aftermarket tool coverage varies by software version and vehicle build — treat "aftermarket tool" rows as "usually possible" and verify against your tool maker's coverage list before promising a customer. Spot a wrong location or hour? Tell us — corrections ship fast here.
ON CERTAIN PASSENGER VEHICLES, THE LOW-BEAM TERMINAL ON THE HEAD LIGHT WIRE HARNESS CAN OVERHEAT AND COULD CAUSE THE LOW BEAMS TO FAIL WITHOUT WARNING.
Consequence: AN UNEXPECTED LOSS OF LOW BEAMS COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT THE HEAD LIGHT SWITCH AND COUPLER FOR SIGNS OF HEAT DAMAGE. IF HEAT DAMAGE IS PRESENT, THE DEALER WILL REPLACE THE SWITCH AND COUPLER. IF NO HEAT DAMAGE IS PRESENT, THE DEALER WILL REPLACE THE HEAD LIGHT SWITCH AND ONE MATING PIN IN THE COUPLER. OWNER NOTIFICATION BEGAN ON APRIL 5, 2004.
