2023 Hyundai Palisade electrical problems

Vehicle loses all electrical power mid-drive, causing dashboard, gauges, radio, and essential controls to go dark. Engine shuts off completely with no warning lights beforehand. Owners report the car becomes unresponsive; brakes and steering may be affected. Multiple owners note a 'Check ESC' code appears on restart.

When: Occurs suddenly while driving at highway speeds or normal traffic conditions; one narrative mentions the issue increases after 45 minutes of high-speed freeway driving

Symptoms owners cite: Dashboard and instrument cluster go black or completely shut off while driving; Radio shuts off simultaneously; Vehicle engine shuts off with no prior warning; Unable to accelerate or brake during shutdown; Check ESC (Electronic Stability Control) message appears on restart; No warning lights or indication before shutdown occurs

Codes mentioned: Check ESC, Computer diagnostic failure code (NG code mentioned in one narrative with 11.90V severely depleted battery)

Repairs/costs cited: Dealership reports difficulty diagnosing because the fault occurs mid-drive. One owner had a starter replacement performed, but the issue continued. One narrative mentions a junction box replacement was attempted for a parasitic battery drain, but the core shutdown issue persisted.

Vehicle battery drains completely while parked, even after replacement and junction box service. Battery goes from normal to completely dead within days or overnight with no warning indicator. One CPO vehicle showed 11.90V severely depleted battery on diagnostic before sale; another owner experienced repeated battery failures despite service attempts.

When: Occurs after vehicle sits for 2-3 days or overnight; one example at 1400 miles (brand new)

Symptoms owners cite: Battery completely drained after sitting for 2-3 days; No warning lights or low-battery indicators before complete failure; Vehicle will not start; Jump-starting works temporarily but battery drains again within days; Multiple recurrences even after battery replacement and junction box replacement

Codes mentioned: NG code (computer diagnostic failure), Check ESC code (in some instances)

Repairs/costs cited: Battery replacement performed; junction box replacement performed. Dealership suspects parasitic drain but has not identified root cause after multiple service attempts.

Brakes suddenly lock or engage while driving, causing the vehicle to stall or become unresponsive. In one critical incident, brakes engaged during a left turn into highway traffic, causing stall in intersection with oncoming traffic. Owners report inability to brake during electrical shutdown events.

When: Occurs without warning while driving, particularly during acceleration or highway turns

Symptoms owners cite: Brakes engage suddenly without driver input; Vehicle stalls in middle of intersection; No horn or headlights work to signal problem; Loss of braking control during electrical shutdown; Violent jolting and uncontrolled vehicle behavior after brake lock

Recalls/TSBs owners mention: Hyundai refused lemon law repurchase claim, stating the issue didn't start until the vehicle could be replicated (February), despite dealer service records documenting issues beginning August 2023. Hyundai instructed owner to continue driving and bring vehicle when problem recurred.

Digital instrument cluster and center infotainment screen fade to black or fail to power on when starting vehicle. Owners unable to see speed, fuel level, warning graphics, or safety information. One narrative reports failure increases on freeway after 45 minutes of driving.

When: Intermittent; increases with highway driving duration; one narrative reports fade-to-black on freeway near Camp Pendleton with recovery after exiting freeway

Symptoms owners cite: Dashboard digital display fades to black or fails to illuminate; Inability to see speedometer, fuel gauge, temperature gauges, or warning graphics; Infotainment system will not turn on at vehicle startup; Instrument cluster displays then goes dark after brief operation; No prior warning before display loss

Repairs/costs cited: Service unable to duplicate issue or find diagnostic codes. One owner reports a recall exists with no remedy that may affect circuitry control system.

Push button start does not engage engine; engine will only start via key fob. Additionally, transmission does not properly engage when push buttons are used to select gears. Vehicle shifts erratically or fails to shift into Park when commanded.

When: Present from new (1400 miles); issue with transmission shifting erratic behavior occurs on every drive

Symptoms owners cite: Engine will not start using push button start; Engine will not start using push transmission gear buttons; Engine starts only with key fob; Vehicle randomly shuts off when parked or powered on; Transmission shifts erratically or loudly; Loud clunking lurch when shifting into Drive or Reverse; Stop-idle function causes lurching and loud clunking; disabled by owner; Transmission will not engage Park when commanded
