My 2008 civic hybrid has a power train issue. Often, when accelerating, the car jumps or jerks. It is almost like you accelerate then brake then accelerate and brake over and over while your foot is only on the gas. This happens regardless of the vehicle's temperature or the weather conditions and happens periodically. It may happen once a week, once every two months or three times a day. I…

What stands out
Owners have filed 45 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 17 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners of 2008 Honda Civics report a range of powertrain failures across manual and automatic transmissions, hybrid systems, and engines. Manual transmission owners cite grinding in 2nd and 3rd gears, gears popping out under load, and complete transmission seizure around 50,000 miles. One owner reported clutch failure at just 16,000 miles. Automatic and CVT owners report slippage, failure to engage properly, and jerking or bucking during acceleration—issues that worsen going uphill or in heavy traffic. Several hybrid owners experienced severe power loss and reduced fuel economy (from 38 MPG to 29 MPG) following Honda's software recall update intended to extend battery life. Hybrid battery overheating disables the electric motor assist on hot days, leaving owners dependent on an undersized gas engine that cannot climb hills safely. Engine surge and unintended acceleration occur without warning, with RPM climbing to 3000+ or 4000 RPM while stopped. One owner reported engine block cracking at low mileage, causing coolant leakage and overheating risk. Automatic transmissions downshift unexpectedly on downhill grades despite driver input. Dealers frequently claim they cannot replicate issues or find no diagnostic trouble codes, even when technicians witness the problems firsthand. Multiple owners note TSBs and silent recalls exist but Honda refuses to address them as safety issues.

Failure modes owners describe
Hybrid battery overheating and power loss on hills in hot weather
Hybrid battery thermal management system disables electric motor assist when battery temperature reaches threshold for safety, leaving car dependent on undersized gas engine. Car loses power, cannot climb hills, or rolls backward on inclines. Occurs in high heat (near 100°F) and high load conditions.
When: 2-5 years of ownership, hot weather, steep hills, stop-and-go traffic
Symptoms owners cite: Loss of acceleration on hills; Car rolling backward despite being in Drive or low gear; Severe power loss after prolonged idling in heat; Inability to merge or climb grades safely
Repairs/costs cited: Honda dealerships confirmed issue via computer analysis and vehicle snapshot data but claimed car operating normally. No repair offered.
Recalls/TSBs owners mention: Honda states this is normal safety behavior and car is safe to drive. No recalls issued.
Hybrid power loss and fuel economy degradation following software recall update
After Honda's software recall update (ostensibly for battery longevity), owners report immediate loss of power, reduced fuel economy (drop from 38 MPG to 29 MPG), and battery failing to assist on hills. Electric motor assist rarely activates even when battery charged. Dealerships deny issue exists.
When: Within days/weeks after software update applied
Symptoms owners cite: Significant drop in fuel economy; Reduced or absent hybrid battery assist; Loss of power during acceleration; Danger during freeway merging; Battery shows low charge (4 blocks or less) and won't assist
Repairs/costs cited: Dealerships say to try higher octane fuel or different brand; refuse to acknowledge software as cause.
Recalls/TSBs owners mention: Recall issued (software update) for battery longevity; Honda denies software caused power loss despite multiple complaints.
Transmission shuddering and vibration during low-gear acceleration from stop
Vehicle shudders, vibrates, and fails to engage smoothly when accelerating from idle into 1st and 2nd gears. Vibration is variable and can be severe enough to prevent safe acceleration. Issue worsens with time and mileage. Dealerships cannot replicate or blame driver technique.
When: Starting around 28,000 miles; worsens over time through 40,000+ miles
Symptoms owners cite: Severe vibration and shuttering from idle to 1st/2nd gear; Jerking or bucking during low-gear acceleration; Vibration stops in higher gears; Unsafe acceleration response; Variable frequency of occurrence
Repairs/costs cited: TSB 08-014 referenced by owner but Honda will not release to consumers. Transmission fluid change provides temporary improvement (less than 1000 miles). One owner reported transmission shaking from clutch release speed feeling, but vehicle is automatic.
Recalls/TSBs owners mention: TSB 08-014 exists but is not accessible to consumers. Dealerships claim no issue found and blame driving technique; some suggest only fluid change, which does not resolve problem.
Manual transmission grinding and gear pop-out (2nd/3rd gears)
Manual transmission grinds when shifting into 2nd and 3rd gears despite shifter aligned correctly. Gears pop out of engagement spontaneously while driving without driver input (clutch pedal not touched). Problem occurs across multiple 2008 Civic Si models and recurs even after repairs.
When: Variable mileage (reported at 50,000+, 55,000+ miles); one reported at low mileage with recurrence
Symptoms owners cite: Grinding noise during shift to 2nd or 3rd gear; Gear pops out while driving; Difficulty or inability to shift into affected gears; Requires excessive force to engage gears; Problem worsens at higher RPMs
Repairs/costs cited: Dealer diagnosis: shift fork failure and 3rd gear synchronizer replacement needed. One owner reports repair cost around $3,000. Problem recurred in same vehicle years later despite prior repair.
Recalls/TSBs owners mention: Owner states Honda has silent recalls and TSBs for this problem but refuses to treat as warranty issue; some dealers refuse to repair.
Automatic transmission slippage and failure to engage under load
Automatic transmission fails to engage smoothly or slips during acceleration, particularly when car is loaded, A/C is running, or on uphill grades. Engine revs but car creeps or does not accelerate. Intermittent behavior makes diagnosis difficult.
When: Variable mileage, intermittent (reported 5 times in 10-month period for one owner)
Symptoms owners cite: Transmission fails to engage or slips; Engine revs but car does not accelerate proportionally; Jerking forward and backward during acceleration; Slow or no response from stopped position; Occurs when A/C on, vehicle loaded, or going uphill
Repairs/costs cited: Taking foot off gas and re-accelerating usually restores normal operation temporarily. One owner believed issue is CVT slippage (in hybrid model).
Engine surge and unintended acceleration while stopped
Engine revs to high RPM (2500–4000 RPM) without driver input while vehicle is stopped at traffic lights, in line at customs, or in parking lots. Vehicle may lurch forward despite brake pedal being depressed. Occurs intermittently, sometimes twice over two years, sometimes multiple times. Restarting engine usually stops the surge.
When: Variable (one owner: first at 45,000 miles, then again at higher mileage)
Symptoms owners cite: Engine revs to 2500–4000 RPM while foot on brake; Vehicle lurches or moves forward unexpectedly; Occurs while stopped at lights or in traffic; Surging stops when engine turned off and restarted; No warning lights or diagnostic codes
Repairs/costs cited: Multiple visits to dealer yield no trouble codes and no diagnosis. One technician found no issue even when engine surged three times during visit.
Recalls/TSBs owners mention: Dealers unable to find any codes in engine computer; area representatives cannot find anything wrong.
Automatic transmission unexpected downshifting on downhill grades
Transmission automatically downshifts on downhill grades without driver command, causing sudden, uncontrolled slowing. Vehicle slows drastically, trapping driver in traffic lane with vehicles approaching from behind. Owner must shift to Neutral to regain control. Related to Honda's Grade Logic Control system malfunction.
When: Variable, on downhill grades (reported on I-15 south of Baker, CA Hwy 101 north of Santa Barbara)
Symptoms owners cite: Unexpected automatic downshift on downhill; Rapid uncontrolled slowing; Loss of driver control over descent speed; Vehicles behind forced to make emergency maneuvers; Occurs multiple times without warning
Repairs/costs cited: Owner diverts to neutral to prevent further slowing. Problem occurs repeatedly.
Recalls/TSBs owners mention: Honda states this is normal behavior.
Engine block cracking and coolant leakage
Engine block develops premature cracks causing coolant leakage. Symptoms appear suddenly: driveway puddles one day, steam and heavy leakage the next. Described as factory defect causing premature cracking. Overheating risk during driving.
When: Low mileage (specific mileage not stated in complaint)
Symptoms owners cite: Coolant leaks on driveway; Steam from engine; Risk of overheating while driving; Sudden onset of symptoms
Repairs/costs cited: Dealer confirmed factory defect in engine block.
Recalls/TSBs owners mention: No manufacturer response noted; covered under warranty.
Clutch failure (manual transmission)
Clutch fails suddenly, rendering manual transmission inoperable. One owner reported clutch quit at highway speed after owning car only one week (purchased as used vehicle). Extremely dangerous when failure occurs at speed.
When: One reported at highway speed with only one week of ownership; other at unspecified mileage
Symptoms owners cite: Clutch quits at highway speed; Complete loss of clutch function; Car unable to be driven
Repairs/costs cited: One owner's dealer refused to repair; attempted to send to auction house. Repair likely to void warranty.
Recalls/TSBs owners mention: American Honda stated they do not get involved with local dealer issues and expressed no concern about NHTSA safety report.
Hybrid jerking and poor acceleration response
Hybrid owner reports car jumps or jerks during acceleration as if alternating between acceleration and braking while foot remains steady on gas. Occurs periodically and unpredictably. Service department acknowledged issue and mentioned recall, but no recall notification received.
When: Periodic (once per week to once per two months to three times per day)
Symptoms owners cite: Jerking or jumping during acceleration; Acceleration-brake-acceleration pattern; Occurs regardless of temperature or weather; Unpredictable frequency
Repairs/costs cited: Service department said problem is under warranty and mentioned recall (not officially notified).
Recalls/TSBs owners mention: Service department acknowledged issue; recall status unclear.
