2006 Chevy convertible corvette (my birthday present to myself) has failed to crank on three different occasions from may 06 through oct 06. The first and second time within a month. Vehicle had to be towed to closet dealership on each occasion. Dealership has been unable to determine cause of problem. Feel uncomfortable in going out of town - don't trust vehicle not to crank. *jb

What stands out
Owners have filed 42 electrical 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.
Among the 17 model years of Chevrolet Corvette in our records for electrical problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2006 Corvette has widespread electrical issues, particularly low-beam headlight failures due to a faulty fuse box that worsens when hot—a safety hazard, especially for night driving. Additional concerns include repeated battery drain, stuck shifters, and faulty traction/active handling systems that can cause unintended vehicle pulling; the recall for headlight failure has had severe parts availability delays.
Owners of the 2006 Chevrolet Corvette have filed 42 complaints centered on widespread electrical failures. The most common defect is low-beam headlight shutdown during operation—lights work cold but fail once the engine heats up, then work again after cooling. Owners report this occurs at highway speeds without warning, forcing them to use high beams or fog lights. The root cause is an expanding underhood bussed electrical center (UBEC) housing creating intermittent fuse box connections, sometimes combined with damaged wiring around tight bends in the harness. GM issued recall 14V251000 in May 2014, but the repair parts remained unavailable for months, leaving owners unable to complete the fix.
Beyond headlights, owners report the vehicle pulling itself sharply to one side while driving, with brake grinding and the traction control or active handling warning lights illuminating—hazardous events that have twice pulled vehicles off interstates. The automatic shifter locks in Park and will not disengage despite brake pedal input. Batteries drain completely even after replacement when the car sits for just a few days, sometimes in cold weather. One owner was trapped inside when electronic door locks failed after a dead battery. Multiple owners describe rough idle, stalling, and check engine lights that dealers cannot diagnose. An alternator that failed six times in succession within two days suggests deeper electrical drain issues. The recall repair for headlights has proved incomplete in at least one documented case, with the same failure recurring months later.

Failure modes owners describe
Low-beam headlight intermittent failure and complete outage
Low-beam headlights shut off or fail to illuminate during normal driving, particularly at night on highways. Owners report the lights work when cold, fail when the fuse box heats up during operation, then work again after the vehicle cools. High beams usually remain functional. The root cause reported by mechanics is the underhood bussed electrical center (UBEC) housing expanding due to heat, creating an intermittent connection in the main fuse/relay backplane circuit. Some owners cite faulty wiring around tight bends in the fuse harness.
When: Intermittent; occurs after vehicle reaches operating temperature or during extended night driving; affects vehicles from 33,000 to 133,900 miles; complaint period spans 2006–2018
Symptoms owners cite: Low-beam headlights shut off without warning during highway driving; Both low beams fail simultaneously; Lights work when fuse box is cold, fail when warm; High beams function normally while low beams are inoperative; Lights may work again after vehicle sits and cools down; Intermittent connection makes diagnosis difficult
Codes mentioned: NHTSA Campaign 14V251000, GM Recall N130146
Repairs/costs cited: Replacement of underhood bussed electrical center (UBEC) housing or main fuse/relay backplane; estimated cost $600–$1,000. Multiple owners report repair parts were unavailable for extended periods (4+ months) after recall issuance. One owner reported a recall repair in April 2015 was documented as completed but was never actually performed; problem recurred in August 2018.
Recalls/TSBs owners mention: NHTSA Campaign 14V251000 (Electrical System, Exterior Lighting) issued May 28, 2014; recall remedy parts were unavailable for months after recall announcement, leaving owners unable to complete repairs. One owner reported faulty wiring found by dealer but GM would not authorize repair. Another owner's recall repair was recorded as completed but was never actually performed.
Traction control and active handling system malfunction with unintended vehicle pulling
Vehicle displays traction control off warning light and service message, then pulls sharply to one direction without driver input, causing brakes to activate and make grinding noise. The brake pedal feels like it is pumping up and down. In reported cases, the vehicle has pulled itself off interstate highways twice, nearly causing wrecks and putting following traffic at risk. Issue appears related to faulty active handling control module wiring harness.
When: Intermittent, triggered by vehicle vibrations (e.g., hitting a bump); problem worsens with increased driving frequency; complaint at 33,000 miles
Symptoms owners cite: Traction control off warning light and service message on dashboard; Vehicle pulls sharply to the left without driver input; Brake grinding noise when unintended pulling occurs; Brake pedal feels like it is pumping up and down; Vehicle pulled off highway twice, nearly causing accidents
Repairs/costs cited: Independent mechanic diagnosed faulty active handling control module wiring harness requiring replacement. No repair cost cited; repair not yet completed as of complaint date.
Recalls/TSBs owners mention: Dealer advised to monitor; said computer diagnostic showed no traction control issue. No recall or TSB cited in narrative.
Low-beam headlight failure after recall repair
Vehicle was serviced under NHTSA Campaign 14V251000 for low-beam headlight failure, but the repair did not resolve the problem. Lights failed again the evening of the recall repair or within a short time after. Suggests the recall remedy was either incomplete or ineffective in some cases.
When: Occurred immediately after or the same evening as completed recall repair; vehicle mileage 133,900 at time of repeated failure
Symptoms owners cite: Headlights failed to illuminate after recall repair was completed; Same symptom as original recall defect returned
Codes mentioned: NHTSA Campaign 14V251000
Repairs/costs cited: Recall remedy was performed but failed to resolve the failure. No follow-up repair attempted or documented.
Recalls/TSBs owners mention: NHTSA Campaign 14V251000 recall was performed; however, remedy did not resolve the headlight failure. Manufacturer was not notified of the failed recall repair.
Excessive battery drain and dead battery when parked
Vehicle battery drains completely while parked for extended periods (as little as 2–4 days) even after battery replacement, or in cold weather (below 45 degrees). Dealer service center staff have reported that electronics in 2006 Corvettes drain batteries while the vehicle sits shut off. Multiple replacements of battery and electronic modules have not resolved the issue in some cases.
When: Occurs after vehicle sits parked for 2–7+ days; worse in cold weather below 45 degrees; complaint period 2006–2008; one dealer car sat for months with repeated dead battery issues
Symptoms owners cite: Battery goes completely dead after 2–7 days of parking; Vehicle will not start after being parked; Occurs even after battery replacement; Worsens in cold weather (under 45 degrees); Vehicle won't start within 4 hours to 2 days of use
Repairs/costs cited: Dealer replaced battery three times, replaced driver-side door module, replaced computer modules and brake switches, but issue persisted. One vehicle was in dealer shop for 25+ days with no resolution. Another required new battery after repair and still would not hold charge.
Recalls/TSBs owners mention: Dealer service addressed with multiple part replacements but could not resolve the root cause. No recall or TSB referenced.
Electronic door lock failure trapping occupants
Electronic door locks and remote entry fail when battery voltage is low (from a dead or depleted battery), trapping the driver inside the vehicle. With doors locked and remote/key also locked inside, the occupant is unable to exit by normal means and must rely on emergency trunk release or manually pull an interior door cable. This creates a serious safety hazard, especially if the vehicle is on fire, in water, extremely hot, or if the occupant is injured, disabled, or a child.
When: Occurs when vehicle battery is dead or critically low; case involved a dealer-owned vehicle that was towed in with dead battery and then was jumped and driven with low battery voltage
Symptoms owners cite: Door locks do not respond to remote key fob when battery is low or dead; Door locks do not open with door handles when battery is low; Occupant trapped inside vehicle with no working exit; Remote control and only key are locked inside vehicle; Doors cannot be opened from outside either
Repairs/costs cited: No repair provided in the complaint narrative. Occupant had to manually find and pull emergency trunk release cable or use trunk release latch to escape.
Recalls/TSBs owners mention: No manufacturer response documented. Complaint notes this issue has occurred to other Corvette owners, including a six-year-old child.
Shift lock solenoid failure—shifter stuck in Park
Automatic transmission shifter gets stuck in Park and will not move into Drive or other gears. The shift lock solenoid fails to disengage when the brake pedal is depressed. Owner reports this is a known problem affecting many 2006 Corvette owners. One owner had the shifter physically replaced years ago but the problem persisted and is occurring more frequently.
When: Occurs at startup and becomes more frequent over time; complaint indicates this is an ongoing recurring problem
Symptoms owners cite: Shifter locked in Park and will not move; Shift lock solenoid does not respond to brake pedal input; Takes anywhere from less than 1 minute to 5 minutes to free the shifter; Problem occurs each time the vehicle starts; Recurring even after previous shifter replacement
Repairs/costs cited: One owner had dealership replace the shifter a few years prior, but problem recurred. Multiple owners report this is a common problem in Corvette forums.
Recalls/TSBs owners mention: No manufacturer response or recall cited.
Alternator repeated failure in rapid succession
Alternator fails repeatedly and is unable to maintain stable voltage output. Owner installed six alternators in a single weekend, each failing within 20 minutes of installation. Check charging system light appears, voltage drops to 11.5 V, new alternator is installed and voltage briefly rises to 14.5 V, then the new alternator fails. Underlying cause not diagnosed despite multiple alternator replacements.
When: Began after owner installed first alternator; repeated failures over two-day period; each alternator lasted only 20 minutes after installation
Symptoms owners cite: Check charging system warning light illuminated; Voltage gauge drops to 11.5 V; Newly installed alternator fails within 20 minutes; Cycle repeats with each new alternator
Repairs/costs cited: Owner installed six rebuilt alternators, each failing in 20 minutes. Planned to take vehicle to a shop for an $800 alternator. Root cause not determined; likely an underlying electrical system problem drawing excessive current or causing overcharging.
Recalls/TSBs owners mention: No manufacturer response documented.
Dash control unit (DIC) flashing and imminent failure
Dash control unit (part number 25938052) is flashing, indicating imminent failure. Failure of this unit would disable defroster capability (front and rear), creating a safety issue while driving in winter. Part is installed in Corvettes from 2006 to 2012 model year. Owner reports visiting five different GM dealers and finding the part is either back-ordered or discontinued. GM has not provided a clear answer on part availability and has stopped responding to owner's communications.
When: Unit is flashing and dealer states it is going to fail; complaint period 2006–2012 Corvettes; owner reports ongoing issue with no resolution
Symptoms owners cite: Dash control unit flashing constantly; Imminent complete failure predicted by dealer; Loss of front and rear defroster capability would result from failure
Repairs/costs cited: Part number 25938052 required for repair. Five different GM dealers report the part is back-ordered or discontinued. Owner attempted to contact Chevrolet online multiple times; they cut off communication and failed to respond to emails.
Recalls/TSBs owners mention: No part availability. Dealers state part is back-ordered or discontinued. Chevrolet customer service stopped responding to owner communications. No TSB or recall provided.
Headlight failure with temperature sensitivity and faulty wiring
Low-beam headlights fail during highway driving, particularly during night driving at highway speeds. Problem is temperature-dependent: lights go out when fuse box reaches operating temperature. Inspection of fuse box revealed damaged wiring around a tight bend that created tension and a faulty connection. Wires in the fuse harness are routed under stress around tight bends, causing insulation damage and intermittent contact.
When: Occurs after vehicle reaches operating temperature during extended driving; failure at 50,000 miles
Symptoms owners cite: Low-beam headlights shut off during highway driving above 25 mph; Lights work when cold, fail when warm; Front brakes may activate without driver input (active handling issue); Low-beam headlights go out while high beams remain functional
Codes mentioned: NHTSA Campaign 14V251000
Repairs/costs cited: Independent mechanic diagnosed faulty wiring harness with damaged wire around tight bend; active handling control module wiring harness also faulty and requires replacement. Photos show tension damage to wire insulation at bend points.
Recalls/TSBs owners mention: Vehicle was previously repaired under NHTSA Campaign 14V251000; however, underlying wiring harness issue was not fully addressed.
Memory seat and electrical function intermittent failure in high ambient temperatures
When ambient air temperature exceeds 95 degrees Fahrenheit, the door-mounted memory button for seat and steering wheel position becomes unreliable. When pressed, the steering wheel moves to preset position but the seat does not move (occurs ~85% of the time). Additionally, in hot conditions with the engine running and A/C and radio on, pressing the memory button causes both the radio and air conditioning to shut off; the radio may restart on its own within a minute but A/C must be manually reactivated.
When: Occurs only when ambient temperature exceeds 95 degrees; does not occur below 80 degrees; thermal sensitivity suggests component stress at high temperature
Symptoms owners cite: Memory button activates steering wheel preset but not seat preset (85% of the time in heat); With engine running and A/C and radio on, memory button press shuts off radio and A/C; Radio may restart within a minute; A/C must be manually turned back on; Problem occurs only above 95 degrees ambient temperature
Repairs/costs cited: No repair documented; issue is electrical and likely related to PCM or module thermal stress.
Recalls/TSBs owners mention: No manufacturer response documented.
Active handling warning light with engine performance change and stall
Active handling system warning light appears on dashboard. Vehicle idles differently and feels like it is missing a cylinder. One owner reported the car stalled while driving 55 mph, and stalling has recurred several times. Dealer codes show normal, and parts replacement has not resolved the issue. Owner believes this is an ongoing dangerous problem.
When: Complaint period includes at least 2006–2015; stalling incidents not dated specifically
Symptoms owners cite: Active handling system warning light illuminated; Engine idle rough, feels like missing cylinder; Vehicle stalled while driving at 55 mph; Stalling recurs multiple times; Brakes feel different during active handling events
Repairs/costs cited: Dealer has scanned codes which show normal; attempted repair with part replacement but stalling persists.
Recalls/TSBs owners mention: No recall or TSB cited.
Vehicle fails to crank / no-start condition
Vehicle fails to crank on multiple occasions, leaving owner stranded. Happened three times between May and October 2006 in the first year of ownership. Each time the vehicle had to be towed to the dealership. Dealers were unable to diagnose the root cause despite multiple service visits. Problem creates unreliability and makes owner uncomfortable driving out of town.
When: Three failures between May 2006 and October 2006 within the first year of ownership
Symptoms owners cite: Vehicle fails to crank and start; No discernible pattern or warning signs; Occurs randomly
Repairs/costs cited: Vehicle towed to dealership each time; no root cause found; no permanent repair identified.
Recalls/TSBs owners mention: No manufacturer response documented; issue never resolved.
