On the 2000-2022 Honda Insight, all Honda Insight generations (2000-2006, 2010-2014, 2019-2022) experience IMA (Integrated Motor Assist) hybrid battery failures, typically between 75,000-175,000 miles (8-15 years). Symptoms include IMA warning light, reduced fuel economy, lack of electric assist, poor acceleration, and frequent battery recalibrations. The battery cells degrade over time, especially in hot climates. First and second generation batteries are more prone to failure. Third generation (2019-2022) batteries have better warranty coverage (8yr/100k miles in CARB states, 3yr/36k elsewhere). Replacement cost: $1,500-4,000 depending on generation.

Common Symptoms

  • IMA warning light on dashboard
  • Reduced fuel economy (MPG drops significantly)
  • Lack of electric motor assist during acceleration
  • Poor acceleration and sluggish performance
  • Battery gauge fluctuating or always empty
  • Frequent battery recalibrations
  • Check engine light with P1xxx hybrid codes

How to Fix

Options: (1) OEM Honda replacement battery ($2,500-4,000 installed), (2) Refurbished battery from specialist like Bumblebee Batteries or HybridReVolt ($1,200-2,000), (3) DIY battery rebuild ($400-800 in parts if mechanically skilled). For 3rd gen (2019-2022), check warranty coverage - 8yr/100k in CARB states (CA, NY, etc). InsightCentral.net forum has extensive guides on battery testing, reconditioning, and replacement. Some owners bypass IMA entirely and run as gas-only ($0-300) but lose hybrid benefits.

Owner tips & cautions

  • TipBattery doesn't "fail" instantly - slow charging/discharging gives warning weeks ahead. Monitor battery gauge and MPG for early detection.
  • WarningHot climates kill IMA batteries faster (Arizona, Texas, Florida). Parking in shade and avoiding extreme discharge extends life significantly.
  • TipDIY rebuild: Individual cells cost $5-10 each (20 cells total). InsightCentral has step-by-step guides - saves $2,000+ if mechanically inclined.

On the 2000-2006 Honda Insight, the 2000-2006 Honda Insight (first generation) experiences premature catalytic converter failures. The lean-burn engine runs very lean, putting extra stress on the catalytic converter. Symptoms include check engine light with P0420/P0430 codes, rattling noise from exhaust, reduced power, and failed emissions test. OEM Honda catalytic converter: $1,200-2,000. Aftermarket: $400-800.

This issue also affects: Acura TSX

Common Symptoms

  • Check engine light with P0420 or P0430 code
  • Rattling noise from exhaust
  • Reduced engine power
  • Failed emissions test
  • Sulfur smell from exhaust
  • Poor fuel economy

How to Fix

Replace catalytic converter with OEM Honda ($1,200-2,000) or high-quality aftermarket like MagnaFlow or Walker ($400-800). Cheap universal cats won't last on lean-burn engine. Address root cause: clogged EGR system can overheat and kill cat - clean EGR before replacing cat. InsightCentral recommends MagnaFlow Direct-Fit cats - last 100k+ miles.

Owner tips & cautions

  • WarningClean EGR system BEFORE replacing cat - clogged EGR overheats and kills new cats within 10k miles. Fix the root cause first.
  • TipAvoid ultra-cheap universal cats ($150-250) - they won't pass emissions on lean-burn Insight and fail quickly. Spend $400+ for direct-fit.
Typical repair cost:$400 - $2,000

On the 2000-2006 Honda Insight, the 2000-2006 Honda Insight first generation with lean-burn engine experiences clogged EGR (exhaust gas recirculation) systems. The EGR valve and passages get clogged with carbon buildup, causing rough idle, hesitation, poor fuel economy, and check engine lights (P0401 code). The lean-burn operation creates excessive carbon. Cleaning EGR system: $150-400. Replacement: $300-600.

This issue also affects: Acura ILX, Acura Integra, Acura MDX

Common Symptoms

  • Rough idle or stalling
  • Hesitation during acceleration
  • Poor fuel economy (MPG drops)
  • Check engine light with P0401 code
  • Engine runs rough in lean burn mode
  • Loss of power

How to Fix

Clean EGR valve and passages with carburetor cleaner or seafoam ($20-50 DIY, $150-400 shop). For severe cases, replace EGR valve ($300-600). DIY cleaning: Remove EGR valve, soak in carb cleaner overnight, clean passages with wire brush. InsightCentral recommends cleaning every 60k-80k miles preventively. Causes catalytic converter failure if ignored.
