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.
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.

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.
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.

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.
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.
