The failure pattern owners describe
A pattern of electrical system failures emerges across this cluster. The most dangerous complaint is engine power loss—the vehicle enters limp mode with a "Reduced Engine Power" message, slowing from highway speeds to 15–30 mph with no warning. Owners report this happens on crowded freeways and in traffic multiple times, sometimes daily. The engine may stall completely at traffic lights or while driving, requiring the owner to restart after waiting minutes. One owner had fuel injectors replaced at 23,000 miles; another had the cylinders replaced. None of these fixes stick. Check engine lights stay on or come back within days, and dealers often claim they cannot diagnose the problem when the light is not actively illuminated.
The second major complaint is the "Shift to Park" error: vehicle refuses to power down even when already in park. Owners must restart and shift between gears repeatedly (reverse, drive, low, park) until the car finally shuts off. One family was locked inside with three children. Dealers replace the shifter harness and battery current sensor for $300–$1,000, but the error recurs.
A third critical failure is total electrical blackout—all lights, radio, dashboard, and power steering warnings vanish while the car is moving. The vehicle stalls and may not restart for minutes. Owners cannot diagnose this because it is intermittent and dealers cannot replicate it.
Hybrid owners report the 12V battery dies repeatedly within two years despite multiple replacements; the issue appears to be electrical drain in the system design, not the battery itself. Water intrusion through a defective brake light has corroded hybrid batteries, with one owner discovering a trunk full of water after months abroad. Interior lighting fails unpredictably—map lights, backup lights, and sunroofs stop working with no blown fuses or bad bulbs.

Failure modes owners describe
Reduced/Loss of Engine Power and Stalling
Engine enters limp mode with 'Reduced Engine Power' or 'Engine Power Decreased' message, dramatically slowing the vehicle to 15–30 mph, often without warning. Vehicle may stall completely while driving, at traffic lights, or during stop-and-go operation. Engine light illuminates; some owners report the vehicle restarts after several minutes or turning ignition off/on.
When: Intermittent, can occur at any speed; some owners report it happens multiple times per day or during highway driving; one owner at 23,000 miles, another at initial ownership with as few as 204 miles
Symptoms owners cite: Check engine light comes on; Dashboard displays 'Reduced Engine Power' or 'Engine Power Decreased'; Vehicle loses acceleration and slows dramatically (15–30 mph); Vehicle stalls without prior warning; Vehicle may not restart immediately; requires waiting or cycling ignition; Occurs intermittently, making diagnosis difficult
Codes mentioned: P2138 (throttle body sensor malfunction), Codes related to accelerator pedal sensor, Codes related to throttle electrical control
Repairs/costs cited: One owner reports fuel injector replacement at 23,000 miles; another had cylinders replaced; accelerator pedal sensor replacement ($200) noted; dealer diagnostics often find no codes when vehicle is not actively failing; some owners report temporary fixes via ECM calibration or sensor replacement, but issues recur
Recalls/TSBs owners mention: GM issued a Technical Service Bulletin regarding this problem 18 months before one owner purchased vehicle; GM has an extended warranty on pedal assembly and TPI sensors; one dealer confirmed this is a known issue on GM cars; no recall issued despite multiple complaints
Shift to Park Error and Inability to Turn Off Vehicle
Vehicle refuses to power down or displays 'Shift to Park' / 'Please Shift to Park' message even when gear is already in park. Owners must restart vehicle and repeatedly shift between gears (R, D, L, P) multiple times before car will finally turn off. Battery may drain if vehicle cannot be shut down. In one case, driver and 3 children were locked in vehicle.
When: Begins around 25,000–60,000 miles; becomes more frequent over time
Symptoms owners cite: Dashboard displays 'Shift to Park' or 'Please Shift to Park' error while car is already in park; Start/Stop button ignition indicator shows car is not in park when it is; Vehicle will not turn off on first attempt; Driver must restart and shift multiple times (R, D, L, P) before shutdown succeeds; Vehicle may remain powered on, potentially draining battery; Children/passengers locked in vehicle in one case
Repairs/costs cited: Dealers have replaced gear shifter (costs noted: $321–$1,000+ range depending on parts/labor); one owner reports $700+ repair quoted; another paid $312–$324 for harness work; replacements include shift harness ($237–$312) and battery current sensor; repairs often do not resolve issue long-term
Recalls/TSBs owners mention: GM issued TSB on 6/7/2021 for 2017–2018 models; TSB provides diagnostic guidance but no definitive solution; one dealer refused to pay for repairs claiming extended warranty was cancelled (disputed by owner); GM customer service refuses to fix per one complaint
Complete Electrical Power Loss and Dashboard Blackout
Vehicle loses all electrical power while driving, causing dashboard, hazard lights, radio, and all instrumentation to black out. Vehicle may or may not restart on its own after several minutes. Often accompanied by loss of power steering assist warning. Owners report this happening at stop lights, on city streets, and highways, with no warning indicators beforehand.
When: Intermittent; some owners report it happening 6+ times in 3 weeks; one owner had repeated incidents from October 2020 onward
Symptoms owners cite: All electrical systems cut out (dashboard, hazard lights, radio, all illuminated displays); Vehicle loses power steering assist capability; Check engine light may briefly appear before blackout; Vehicle stalls; must wait for it to restart; No warning indicators before failure; After restart, 'Stabilitrak' and 'Steering Assist Reduced' messages may appear
Codes mentioned: No codes found in OnStar scan in one case, Some codes related to secondary battery short (one hybrid)
Repairs/costs cited: One owner had secondary battery (trunk-mounted in hybrid) replaced due to short that burned cable; dealers have been unable to replicate issue or find cause; no repairs successful despite multiple visits; one owner has vehicle still with independent mechanic
Recalls/TSBs owners mention: Dealers claim unable to replicate issue and unable to diagnose without active fault codes; manufacturer not notified in some cases; one owner reported dealer said they cannot diagnose if MIL light is not currently on
Auto Start-Stop Feature Malfunction
Auto Start-Stop feature fails to restart engine after stopping, or engages at inappropriate times (e.g., when foot is no longer on brake). Vehicle may require manual restart or fail to reengage. Some owners report the feature causes excessive battery drain.
When: Recurring issue; one owner reports third dead battery within 2 years; one incident at school drop-off
Symptoms owners cite: Engine shuts off via Auto Stop but does not restart when brake pedal released; Feature engages when brake is not depressed; Starter motor must be replaced to resolve; Vehicle loses electrical power when feature malfunctions; Dashboard and radio turn off during Auto Stop engagement
Repairs/costs cited: Starter replacement performed at dealer; battery replacement performed (multiple times in some cases: one owner replaced battery 3 times in 2 years, each time dealer replaced it); repairs do not prevent recurrence
Recalls/TSBs owners mention: One owner notes sales staff said this is 'normal' behavior; dealer stated Auto Start feature affects battery life
Repeated Battery Failures (12V)
Battery dies prematurely while vehicle is parked; multiple replacements required within short timespan. One hybrid owner experienced 3 dead batteries within 2 years; another experienced dead battery at startup. Issue appears related to electrical system design rather than defective batteries.
When: One hybrid owner: 1st dead battery within 1 year; 2nd in June 2019; 3rd after parking for 7 hours in September 2019
Symptoms owners cite: Battery dies while vehicle is parked or stationary; Vehicle cannot be started after parking; Stabilitrak light and steering assist reduced warning may appear concurrently; Multiple replacements do not resolve issue
Codes mentioned: B1325 (Low Voltage Code; one owner notes battery shorted cell)
Repairs/costs cited: One hybrid owner paid for battery replacements out of pocket (not warranty) despite vehicle being new; dealer replaces battery each time but does not address underlying electrical system drain; one owner reports replacing battery for $290 on 2-year-old vehicle
Recalls/TSBs owners mention: Dealers recommend battery replacement; GM recommended battery cell replacement (owner notes this has been done each service visit); no investigation into electrical system design
Stabilitrak and Power Steering Warnings (Non-Critical Failures)
Stabilitrak and Power Steering Assist warnings illuminate intermittently or persistently despite no actual loss of steering capability. Warnings may be accompanied by reduced steering response or false alerts that resolve after vehicle restart.
When: Can occur at any time; often during Auto Stop or electrical power fluctuations
Symptoms owners cite: Stabilitrak warning light flickers on/off while driving; Dashboard displays 'Steering Assist Reduced' or 'Steering Assistant Reduced—Drive with Care'; Power steering assist warning illuminates; Warnings resolve after vehicle restart; No actual loss of steering function reported in most cases
Repairs/costs cited: No repairs documented for this issue; mechanics unable to pinpoint cause; one mechanic suggested following GM flow chart for diagnosis (which could result in extensive labor costs)
Recalls/TSBs owners mention: GM flow chart for diagnosis provided by mechanic; no recalls or TSBs specific to this issue noted
Check Engine Light Persistent Illumination and Sensor Issues
Check Engine light remains on continuously or illuminates repeatedly despite repairs. Dealers replace various components (O2 sensor, fuel injector, ECM, accelerator pedal sensor, throttle body sensor) but light returns within days or weeks. One owner notes dealer 'cleared the light in hopes that would fix the problem.'
When: Present from early ownership (one owner: 11 miles on ODO at purchase); recurs shortly after repair (one case: light returned 48 hours after dealer 'fix')
Symptoms owners cite: Check engine light remains on permanently or turns on/off intermittently; Light returns shortly after dealer repair; Fuel smell or emissions issues reported by some owners; Engine sounds rough or unstable when shifting gears
Codes mentioned: P2138 (throttle position/pedal sensor), O2 sensor faults, ECM-related codes
Repairs/costs cited: Repairs include: O2 sensor replacement ($143.92 parts + $420 labor per one invoice); ECM calibration update; fuel line/gas cap leak detected (part unavailable from GM per one case); fuel injector cleaning and system flush; fuel injectors replaced
Recalls/TSBs owners mention: One dealer stated issue 'not uncommon on GM cars'; extended warranty on pedal assembly and TPI sensors mentioned; dealers perform repairs but do not resolve root cause
Water Intrusion Into Trunk and Electrical Damage (Hybrid Models)
Water enters trunk through defective center high-mounted stop lamp (CHMSL), causing corrosion of hybrid battery and electronic components. Metal items oxidize; electrical system failures follow. Corrosion is irreversible and shortens hybrid battery lifespan.
When: One owner discovered issue upon return from extended overseas trip in 2019; GM had issued recall letter
Symptoms owners cite: Water accumulation in trunk; Metal oxidation and corrosion of hybrid battery; Electrical component failure due to water intrusion; Premature degradation of hybrid battery
Repairs/costs cited: Water intrusion address requires replacement of defective CHMSL fasteners; hybrid battery corrosion cannot be undone; repair of water damage included trunk carpet and molding replacement (one owner: 4-week repair duration)
Recalls/TSBs owners mention: GM issued recall letter regarding water intrusion through CHMSL; one owner reports this was deemed a recall and trunk carpet/headliner/molding replaced
Fuel Gauge and Fuel System Issues
Vehicle will not fill completely at fuel pump; gauge reports less fuel than actually in tank. Dealers perform fuel gauge recalibration with no lasting fix. One owner reports continuous fuel smell and difficulty filling tank.
When: Ongoing since purchase for one owner
Symptoms owners cite: Vehicle will not accept full tank of fuel at pump; Fuel gauge underreports fuel level; Fuel smell reported by one owner; Fuel line leak detected in one case (gas cap area)
Repairs/costs cited: One dealer performed fuel gauge recalibration; another detected fuel line leak at gas cap area but part was unavailable from GM at time of complaint
Recalls/TSBs owners mention: Dealer offered recalibration; no long-term solution
Backup Lights and Interior Lighting Failure
Backup lights, map lights, and sunroof lighting fail without burned-out bulbs or blown fuses. Mechanic inspection confirmed no electrical component defects, but lights remain inoperative. Sunroof also fails to open.
When: One owner: noticed months after purchase (56,000 miles on vehicle at time of complaint); issues present from 25,000 miles
Symptoms owners cite: Backup lights will not illuminate despite good bulbs; Map lights will not turn on; Sunroof will not open; No blown fuses detected; All bulbs test functional
