What stands out
Owners have filed 28 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 19 model years of Toyota Tundra in our records for electrical problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
A new head unit software update is available for 2022 – 2025 model year Tundra, and Tundra Hybrid; 2023 – 2025 model year Corolla Cross, Corolla Cross Hybrid, Highlander, Highlander Hybrid, Mirai, and Sequoia Hybrid vehicles equipped with Toyota Multimedia versions earlier than version 2230.

The failure pattern owners describe
The 2024 Tundra shows a pattern of electrical and software failures starting early in ownership. Fuel gauge resets to full without refueling—sometimes five to six times within the first 2,300 miles—forcing owners to track mileage manually. Dealerships confirm the issue is repeatable but Toyota has offered no fix.
Throttle response is a safety concern. Owners describe pronounced hesitation (2–3 second delay) when accelerating from stops, happening daily and worsening over time. Worse, some trucks lose throttle response entirely at intersections for several seconds, creating near-miss traffic accidents. Dealers say they cannot duplicate the problem.
Camera systems fail early: rearview cameras display frozen or black screens while in reverse, backup guidelines disappear, and all truck cameras sometimes disable at once—defeating parking safety. Software updates have not resolved these issues.
Cruise control and collision braking systems disable along with check engine lights, forcing owners to buy diagnostic tools just to clear codes. After eight dealership visits, one owner got no permanent repair.
Infotainment screens black out, lose programming, or display GPS only for front parking lines. Doors lock and won't unlock via proximity sensors or digital key app. Second key fobs promised at purchase never arrived, with delivery dates pushed back repeatedly across months.
One owner reported their truck burst into flames while parked—no warning lights beforehand.

Failure modes owners describe
Fuel Gauge Resets to Full
Fuel gauge displays full tank without refueling, resetting independently. Multiple owners report this happening frequently (5-6 times within first 2,000-2,300 miles in some cases). Dealer investigation confirms the issue is repeatable; Toyota acknowledges the problem but has offered no repair remedy.
When: First 2,000–2,300 miles; occurs at multiple intervals thereafter. Often happens when vehicle is parked, especially on inclines.
Symptoms owners cite: Gauge resets to full without fuel being added; Miles-to-empty recalculates incorrectly; Gauge may display false 153% fuel level in digital account; Gauge fails to return to accurate reading until vehicle is driven or reset electronically
Repairs/costs cited: Dealership has investigated multiple times (three or more visits per owner); no permanent fix applied. Some owners advised to track mileage manually instead of relying on gauge. Location of fuel gauge sending unit in fuel tank cited by Toyota as possible cause.
Recalls/TSBs owners mention: Toyota acknowledges problem but states it may be due to elevation, parking angle, or fuel tank sending unit location. No TSB or recall issued. Toyota Customer Fulfillment case numbers opened but no remedy timeline provided.
Throttle Hesitation and Delayed Acceleration
Engine exhibits pronounced hesitation or lag when accelerating from stop or low speed, with a 2–3 second delay before power engages. Owners report this occurs daily and has worsened over time. In some cases, throttle becomes unresponsive (goes dead) for several seconds at traffic lights and intersections, creating serious safety hazards.
When: Recurring throughout ownership, happening at every stop sign or intersection in some vehicles; one owner specifically notes 7/8/25 and recent occurrences.
Symptoms owners cite: 3-second delay or hesitation during acceleration from stop; Transmission slow to shift into 1st gear at stops; Throttle unresponsive for several seconds at intersections (throttle 'goes dead'); When throttle returns, sudden full power engagement if pedal held down; Engine sluggish when starting from complete stop; Hard shifting between stop and go
Repairs/costs cited: Dealership reports inability to duplicate the issue during diagnostics. One owner notes Toyota attributed issue to double-foot pedal technique (owner denies this practice). No repair performed.
Recalls/TSBs owners mention: No recalls or TSBs cited for this issue. One owner references Safety Recall 25TA14 (V35A engine stall due to manufacturing debris) but no direct connection to throttle hesitation confirmed in narratives.
Rearview and Backup Camera Malfunction
Rearview camera displays frozen image, black screen, or no image while in reverse. Backup camera guidelines (parking lines) stopped displaying. Front-facing camera display shows when in reverse (instead of rear view). All camera functions disabled in some cases.
When: Early in vehicle operation; one owner reports issue at approximately 4,000 miles.
Symptoms owners cite: Rearview camera shows frozen or black screen in reverse; Backup camera guidelines/lines not displayed; Front camera display shows instead of rear camera; All cameras around truck disabled, preventing safety checks; Unable to select different camera views
Codes mentioned: Lost Communication with Image Processing Module 'B' Missing Message
Repairs/costs cited: Dealer updated software; issue persisted. Vehicle not inspected or diagnosed on second visit; not repaired.
Recalls/TSBs owners mention: Manufacturer notified but no assistance provided. No TSB or recall mentioned.
Cruise Control and Collision Avoidance System Disabled
Cruise control and collision avoidance/braking assistance features become disabled, sometimes in conjunction with check engine light or evaporative emissions fault codes. In one case, throttle unresponsiveness at intersections may be related to collision avoidance system cutting throttle without warning or alert.
When: Recurring over 6-month period (March 2024 onward in one case); ongoing at time of complaint.
Symptoms owners cite: Check engine light illuminates and disables all cruise control functions; Collision braking assistance fails; Collision avoidance system may cut throttle without beeping or warning; Fatigue-reducing cruise control unavailable on long trips
Codes mentioned: P2450 7E, Evaporative Emissions System Switching Valve Actuator Stuck On, Evaporative Emission System Switching Valve Performance/Stuck Open
Repairs/costs cited: Owner purchased Launch code reader to manually clear codes. Dealership unable to repair; stated need for Toyota factory technician. After 8 dealership visits, issue remained unresolved.
Recalls/TSBs owners mention: Dealership unable to provide remedy; no TSB or recall issued. No factory technician intervention occurred despite request.
Infotainment System Failures
Infotainment center blacks out, loses programming, displays only backup/front parking lines without full display, or goes blank. GPS linked to phone screen blacks out while phone GPS continues to work. Hands-free phone calling occasionally disconnects.
When: Recurring throughout ownership; one owner reports multiple visits for same issue.
Symptoms owners cite: Infotainment screen blacks out; Marker bars and backup/front parking lines disappear; GPS display blacks out (phone GPS remains functional); System 'forgets' programming; Hands-free phone calls disconnect occasionally
Repairs/costs cited: Toyota performed factory reset (unsuccessful). Technician reinstalled program. Dealer indicates this is a 'known issue' where system forgets programming.
Recalls/TSBs owners mention: Toyota acknowledged seeing the sluggish engine behavior but attributed it to double-foot pedaling (owner disputes). Known issue identified but no repair remedy provided.
Door Lock and Key Fob System Failures
Driver's door lock fails to engage via proximity sensor or digital key app. Second key fob never delivered despite promises spanning months (January through August per one owner).
When: First incident at unspecified time; key fob delay 5–6 months after purchase for multiple owners.
Symptoms owners cite: Driver's door locks and cannot be unlocked via proximity sensor; Digital key app reports unlock feature unavailable; Second key fob not provided at delivery; promised dates repeatedly missed; Manual unlock via interior handle required as workaround
Repairs/costs cited: Manual unlock via passenger seat required for one owner. No repair attempted for key fob delay; only repeatedly broken promises of future delivery.
Recalls/TSBs owners mention: No recall or TSB issued. Dealer and corporate contacts have repeatedly changed anticipated delivery date without resolution.
Forward-Facing Camera Lens Crack
Front grille camera lens cracked, rendering camera inoperable. Owner believes crack is a defect rather than impact damage, as no visible impact damage is evident around the camera.
When: Noticed approximately 1 year after purchase (around January 2025 if purchased January 2024).
Symptoms owners cite: Camera lens cracked; Camera unusable for intended function; No visible external damage to surrounding area
Repairs/costs cited: Not yet inspected by dealer. Owner obtained replacement estimate from dealer.
Recalls/TSBs owners mention: No response documented.
Engine Power Loss and Limp Mode Activation
Vehicle enters limp mode and shuts down while driving, displaying 'Reduce Engine Power' message. In one case, all mercy braking and collision malfunction sensors simultaneously failed. Engine knocking noise present (compared to being without oil) despite recent oil change and no low-oil warning.
When: Multiple instances starting a few months into ownership; latest incident most severe.
Symptoms owners cite: Vehicle reduces power and enters limp mode while driving; Engine shuts down during operation; Check engine light; 'Reduce Engine Power' message displayed; All collision braking and malfunction sensors fail simultaneously; Engine knocking/rattling noise (like no oil present); No low-oil warning despite recent oil change
Repairs/costs cited: No specific repair mentioned. Dealer identified this as manufacturing issue but stated no recall exists.
Recalls/TSBs owners mention: Toyota acknowledged manufacturing issue but no recall issued at time of complaint.
Reverse Light Not Working
Reverse light fails to illuminate, preventing driver from clearly seeing while reversing.
When: Timing not specified.
Symptoms owners cite: Reverse light does not work; Inability to see clearly while reversing
Engine Fire
Vehicle burst into flames while parked and not running in driveway. Large fire and explosions destroyed front half of vehicle and entire engine compartment. No warning lights or prior issues reported before fire.
When: While parked, not running.
Symptoms owners cite: Vehicle burst into flames while parked; Large fire and explosions; Front half and entire engine compartment destroyed; No warning lights or prior indicators

What owners are reporting 2 most recent
The lens on the forward facing camera in the front grill cracked making the camera useless and in need of replacement. I first noticed the problem about a year ago. It is available for inspection. I can't see any damage around the camera that would have been caused by an object hitting the front of the truck which leads me to believe that the camera lens cracked because of a defect. The camera…
Both passenger seats by controls plastic cracking. Infotainment center blacks out and marker bars and back up lines for both back up and front parking have disappeared. GPS even when linked to my phone screen will black out but phone gps will still work. I have complained about this multiple times. Toyota did a factory reset on it and didn’t fix the issue took it back and a tech had to re-install…
