2010 Chevrolet Malibu electrical problems

Brake lights illuminate without brake pedal pressure and fail to illuminate when brake pedal is pressed. Service ESC, Service Traction, ESC Off, and Engine Power Reduced warnings appear on the dashboard. Cruise control becomes inoperable. Some owners describe intermittent failures that persist or recur even after recall repairs. Owners report replacing brake pedal position sensors multiple times without resolution.

When: Starts intermittently, can occur at any mileage, some owners report issues within months of purchase, others after several years. One owner at 59K miles, another at 100K, others at 140K miles.

Symptoms owners cite: Brake lights on without pedal pressure, off when pedal pressed; Service ESC, Service Traction, ESC Off warning lights; Engine Power Reduced message; Cruise control disabled or non-responsive; Car shudders or jerks; Vehicle loses power or acceleration; Car stalls or goes into limp mode; Traction control and stability control disabled

Codes mentioned: P2135 (TPS - Throttle Position Sensor), C0242, P0300 (Engine Misfire), Communication errors

Repairs/costs cited: Recall 13036D and 14V252000 address BCM wiring harness connection and brake pedal position sensor calibration. Dealers often recommend BCM replacement ($600+), brake pedal position sensor replacement ($200-$272), or brake switch calibration ($50). Many owners report repairs fail or problem recurs within days to weeks. One owner replaced brake switch, then bracket in rear window ($402.40). Dealers sometimes refuse to reopen recalls, charging diagnostic fees ($150+) for subsequent visits.

Recalls/TSBs owners mention: Recall 13036D (2004-2012 Malibu) and 14V252000 for brake lamp malfunction and electrical system issues. Recall involves attaching wiring harness to BCM with spacer, applying dielectric lubricant, and relearning brake pedal home position. Special warranty program mentioned (150,000 miles or year 2025) for some owners. Many owners report recalls were performed but failures persisted or recurred. Some owners found their VIN was not included in recall when they checked.

Vehicle loses power or speed while driving, engine runs roughly, and Service ESC or Engine Power Reduced messages illuminate. Owners report the car slows to approximately 20 mph with erratic RPM and violent shaking. Multiple mechanics have misdiagnosed the issue, with some recommending expensive teardowns. Owners describe water infiltration into electrical connections and poor connections at the throttle position sensor as the likely cause.

When: Occurs after hitting bumps, while idling, while driving at various speeds, intermittently over months or years. One owner reports issue since 2016, another since 39K miles. One owner experienced it while driving 35 mph in traffic, another at 55 mph on dark road.

Symptoms owners cite: Complete loss of power or severe power reduction; Vehicle slows to 20 mph; RPM erratic or jumps; Car shakes violently; Service Traction, Service ESC, ESC Off, Engine Power Reduced warnings; Engine light stays on; Jerking or lurching forward; Loss of power steering and brakes (partial); Car stalls or dies in traffic

Codes mentioned: P2135 (TPS - Throttle Position Sensor), P0300 (Engine Misfire), APP sensor 1 and APP sensor 2 disagreement >4.5%

Repairs/costs cited: Owners replaced throttle body twice, accelerator pedal three times, battery, MAP sensor, knock sensor, spark plugs, and cleaned corrosion. One independent mechanic diagnosed poor electrical connection between wire harness and computer due to water intrusion. AutoZone diagnosed APP sensor 1 and 2 disagreement. One dealership wanted $2,300 for engine teardown (later deemed unnecessary). Chevrolet dealer unable to fix in July 2016.

Recalls/TSBs owners mention: GM sent letter about throttle position sensor issue. No formal recall identified in narratives for this specific failure mode, though owners describe it as well-known to Chevrolet.

Dashboard lights, headlights, taillights, brake lights, turn signals, and interior lights intermittently fail or malfunction. Lights may go off while driving and return when hitting a bump. Some lights work inconsistently depending on whether other lights are on. One owner reports wipers broke twice. Owners cite poor wiring, corrosion, or design flaws in the electrical system.

When: Can occur from early ownership through higher mileage. One owner experienced dashboard light failure from time car was new. Headlight bulbs failing repeatedly (owner reports 5-6 replacements in 3 years). Wiper failure occurred while driving on crowded highway in rain.

Symptoms owners cite: Headlights go out at night, come back on with bumps; Dashboard lights not illuminating or going off while driving; Turn signals intermittently non-functional or delayed to activate; Interior and exterior lights randomly on or off; Brake lights work intermittently; Wipers malfunction or quit working; Gauge cluster lights fail to illuminate at night; Temperature gauge flashes with numbers then lines

Repairs/costs cited: Headlight bulb replacements (5-6 times in 3 years) at $180+ per service due to design requiring bumper removal. Owners cite complex removal process, with some shops refusing work due to labor intensity. Wiper repairs repeated twice. One owner replaced passenger-side headlight, failed again one week later. Some owners describe design flaw in daylight running time circuitry causing high currents, overheating, melting/deformed connectors and pigtails.

Recalls/TSBs owners mention: No recalls mentioned for lighting issues in these narratives. One owner mentions notice about taillights issue but no specific recall identified.

Vehicle suddenly loses all electrical power while driving—engine shuts off, dashboard goes dark, no lights, no power steering/brakes available temporarily. Some incidents result in complete restart failure requiring towing. One vehicle caught fire in parked engine compartment. Owners report this is extremely dangerous, particularly on highways in traffic.

When: Can occur early in ownership (one at 400 miles) or later. One owner reported incident at 70 mph on Garden State Parkway in traffic; another at 55 mph on dark road with passenger. One vehicle caught fire while parked (new vehicle, January 2011, ~2-3 months after November 2010 purchase).

Symptoms owners cite: Complete engine shutdown while driving; Total loss of electrical power—no dash lights, no turn signals, no hazard lights; Loss of power steering and power brakes temporarily; Vehicle will not restart (sometimes takes several attempts or an hour); Dashboard resets internal clock to 1/1/2009 after restart; Engine catches fire in engine compartment while parked; Ice possible and ABS failure warnings followed by complete power loss; Vehicle cranks but does not start after initial stall

Repairs/costs cited: Dealerships diagnosed fuse panel, computer issues, and ground problems (104 & 107 mentioned). Global reset performed. One owner had new fuse panel installed. No permanent fix documented. Fire department ruled the parked fire a defect. Owner not given root cause by dealer and no vehicle replacement or reimbursement.

Recalls/TSBs owners mention: No recalls mentioned for stalling/power loss in narratives. Dealership addressed some incidents but root cause not identified. One owner mentioned GM bailout by government and taxpayer funds.

Driver-side door (and occasionally other doors) will not open from inside or outside despite being unlocked. Door appears to not latch or unlock properly. Intermittent failure—door may work for days then stop working again. Classified as major safety issue, especially in emergency or accident situations.

When: One owner reports issue starting June 8th (2015), intermittent over ~2 months. Another owner reports issue before 50K miles.

Symptoms owners cite: Driver-side door will not open from inside when door is unlocked; Driver-side door will not open from outside by pulling handle; Latch does not appear to engage with components; Intermittent failure—works for days then stops; Must climb over to driver's seat to enter vehicle

Repairs/costs cited: Tried penetrating oil and grease to lubricate actuator with no fix. Repair costs quoted upwards of $350. One owner left vehicle parked for nearly 2 months (waiting 3 weeks for dealer appointment) and used public transportation instead.

Recalls/TSBs owners mention: No current recalls identified for door latch issue. Dealer appointment wait times lengthy (3 weeks reported).

Headlight bulbs fail repeatedly—owner replaced both bulbs 5-6 times in 3 years, with some replacements happening only weeks after prior replacement. Both driver and passenger sides affected, often replaced together due to access difficulty. Root cause suspected to be daylight running light (DRL) circuitry causing high currents and overheating.

When: Failures recurring over 3-year period. Exact timing varies from weeks to months between failures.

Symptoms owners cite: Headlight bulbs burn out frequently; Both driver and passenger sides failing; Bulbs fail weeks after replacement; Intermittent headlight operation

Repairs/costs cited: Bulb replacement cost $180+ per service. Complex design requires removal of front bumper and multiple components, making it labor-intensive (>$200+ typical cost). Many repair shops refuse to service due to time and complexity. Owner had to miss work or leave early for repairs. Online searches indicate many owners with similar problem.

Recalls/TSBs owners mention: No recall issued. Design allows no DIY repair. Internet searches show many customers with similar issue pointing to failed DRL circuitry design by Chevrolet.

Transmission does not shift smoothly or in a timely manner while driving. Transmission component (piece connecting to transmission) comes undone, causing vehicle to not shift gears. In some instances, vehicle goes into Park but continues to move, requiring emergency brake to stop. Clicking noise at CV transmission entry point suggests internal gear play.

When: One owner at 59K miles. Issues reported across various mileages.

Symptoms owners cite: Transmission takes forever to shift; Clicking noise when placing car in drive and beginning to move; Transmission piece comes undone; Vehicle cannot shift gears after piece undone; Vehicle goes into Park but continues to move; Vehicle goes into Park, cannot be shifted

Repairs/costs cited: Mechanic suggested internal gear play within transmission. One owner owes over $10K on vehicle. Dealer appointment pending but issues occurred before appointment.

Recalls/TSBs owners mention: Dealer appointment scheduled; one owner noted this is second transmission issue from same dealer in 2 years.

Vehicle enters 'limp' mode and Service lights illuminate after rain or car wash. Car may lose power entirely if driven in rain. Owner has avoided driving in rain for 4 years; dealer acknowledged this is an inherent problem. Root cause (specific wetted component) unknown to owner and dealer.

When: Occurs whenever vehicle exposed to rain or car wash; has persisted for 4 years of ownership.

Symptoms owners cite: Vehicle enters limp mode in rain or after car wash; Service lights come on and remain on until car dries; Vehicle may lose power if driven in rain; Problem repeats consistently whenever exposed to moisture

Repairs/costs cited: Owner avoids driving in rain. Dealer investigated but could not identify water entry point or component.

Recalls/TSBs owners mention: Dealer acknowledged as inherent problem. GM customer service representative reported other calls with same complaint but unknown if investigation ongoing.

Air conditioner blows hot air and fails to maintain temperature, particularly in hot weather. Passenger suffered asthma attack due to excessive heat in vehicle. Dealer replaced computer chip twice without resolving issue.

When: At 2,600 miles (very early in vehicle ownership).

Symptoms owners cite: Air conditioner blows hot air; Temperature control unresponsive in 95-degree weather; Vehicle becomes dangerously hot

Repairs/costs cited: Dealer replaced computer chip twice. Second replacement did not remedy issue. Owner forced to call taxi cab to get passenger medical care.

Recalls/TSBs owners mention: Dealer attempted repair. Manufacturer stated it was up to dealer to fix. No response to owner's letter detailing problems.

Side impact airbag did not deploy in 35 mph hit-and-run collision. OnStar response system did not detect crash and call for help. Driver seat airbag and passenger seat module failures occurring with no clear root cause. Some owners report airbag warning lights coming on for unknown reasons.

When: Airbag non-deployment during hit-and-run in March 2017. Seat airbag failures at higher mileage. One owner experienced airbag light and other warning lights toggling on and off.

Symptoms owners cite: Side impact airbag did not deploy on impact at 35 mph; OnStar crash detection system did not activate; Driver seat airbag failure; Passenger seat module failure; Service airbag light illuminates; Airbag warning lights toggle on and off with other electrical issues

Repairs/costs cited: Dealership unable to explain why side impact airbag did not deploy (not attributed to Takata recall). Replacement of driver seat airbag and passenger seat module quoted at $1,245.87. Owner questions why vehicle of this age should have airbag failures.

Recalls/TSBs owners mention: Takata airbags were recalled and replaced. Dealership unable to explain non-deployment or identify root cause of seat airbag failures. No safety recall identified for these failures.
