3rd Gen Tundra Troubleshooter

Tell it what the truck is doing. You get the checks in the order an experienced owner would run them: cheap and likely first.

3rd generation Tundra, 2022 on, with the 3.4L twin-turbo V35A-FTS V6 and the 10-speed automatic, including the i-FORCE MAX hybrid. Most items are covered by Toyota's 3 year/36,000 mile basic and 5 year/60,000 mile powertrain warranties or by an open recall, so the first check on this truck is usually a VIN lookup.

8 symptoms

EngineKnock from the engine, rough running, stall or no-start (main bearing recall)

Three NHTSA recalls now cover machining debris left in the V35A that can wipe out the number one main bearing: 24V381 (2022–2023, engine replaced), 25V767 (2022–2024 expansion with a bearing inspection) and 26V320 (2024 trucks built February to August 2024). A new knock, rough running, metal in the oil or a sudden stall on a 2022–2024 gas Tundra is this recall until proven otherwise.

Safety: A bearing failure can stall the engine without warning. If you hear a new knock, stop driving and have it towed to a dealer; driving on it can turn a covered repair into an argument.
  1. Run the VIN
    nhtsa.gov/recalls or a Toyota dealer shows which campaign your truck is in and whether the work is done. Toyota revised the bearing from July 2024 production, but 26V320 still covers 2024 trucks built through early August.
    easy$
  2. Listen and look
    A deep knock at idle that gets louder under load, an oil pressure warning, or glitter on the dipstick or in the filter are the signs. Cold-start rattle that fades in seconds is more likely the wastegate or an exhaust shield; see those symptoms.
    easy$
  3. What the dealer does
    Under 24V381 the engine is replaced. Under 25V767 and 26V320 the dealer inspects the number one bearing using Toyota's software and drive data and replaces the engine only if needed. Keep oil change records; they are not a condition of the recall but matter if coverage is disputed for a truck just outside a VIN range.
    hard$
  4. Outside the campaigns
    A 2022–2024 truck with a knock that a dealer says is not covered deserves a second dealer and a call to Toyota's customer line with the VIN and build date. Owners near the edges of the build windows have reported disputes.

Engine"Reduced engine power" warning with P0243 or P0247, or a rattle from the turbos at idle

Early 2022 trucks had a batch of bad wastegate actuators that set P0243 or P0247 (wastegate actuator A) and a reduced power warning; Toyota's tech tip T-TT-0681-22 covers the codes and the fix was a turbo and manifold assembly under warranty. A light metallic rattle from the turbo area at idle is a separate owner complaint, usually the wastegate flapper or linkage, and we found no Toyota bulletin for it.

  1. Codes first
    P0243 and P0247 are the wastegate actuator circuits for each turbo; P0299 is underboost. With the reduced power message these are warranty claims, and the tech tip tells technicians to consult Toyota before replacing a turbo, so expect a diagnostic visit rather than parts off the shelf.
    easy$
  2. Locate a rattle
    At idle, have a helper blip the throttle while you listen at each turbo. A rattle that changes when you press on the actuator rod is the flapper or linkage. A rattle that moves with the exhaust is a heat shield; see the exhaust rattle symptom.
    easy$
  3. Check for leaks around the turbos
    Coolant or oil residue on the turbo housings or the smell of coolant after a drive means a line or seal, which is also warranty work. Owners have chased slow coolant loss to the turbo and valley area.
    medium$
  4. Warranty position
    Turbos are powertrain parts under the 5 year/60,000 mile warranty. Out-of-warranty prices for the V35A turbo assemblies were not something owners had reported as of this writing.

TransmissionPop or clunk under the truck on the first start of the day, hesitation coming to a stop, harsh 1–2 shift

Toyota issued two bulletins for the 10-speed in December 2022: T-SB-0110-22 for a loud pop or clunk under the truck on the first start after sitting, and T-SB-0111-22 for hesitation coming to a stop (worse cold) and a surge in 8th gear at part throttle. Both are transmission control module reflashes. A separate recall, 24V125, reprograms the TCM so the truck cannot creep in Neutral with the brakes off.

  1. Check the calibration
    Ask the dealer to confirm the TCM is on the latest calibration and whether the two 2022 bulletins and recall 24V125 have been applied. Reflashes are free under warranty or the recall.
    easy$
  2. Separate transmission from driveline
    A clunk that happens when you shift from Park to Drive or at the first tip-in is often driveline lash. On 2022 trucks, recall 22V445 covered rear axle flange nuts that loosen; a clunk plus a vibration or a wet hub needs the axle checked.
    easy$
  3. Harsh first shift of the day
    Owners report a firm 1–2 on the first drive and a 2–1 clunk coming to a stop, mostly cold, after the reflashes. Document it with dates and temperatures; Toyota has continued to issue software updates for the 10-speed, and a dealer can check for newer ones.
    easy$
  4. Fluid
    The 10-speed uses Toyota WS and is checked at temperature through an overflow plug. A leak at the extension housing on 2WD trucks was covered by tech tip T-TT-0679-21. Low fluid will cause flare and harsh shifts no software fixes.

Hybrid System"Hybrid system malfunction" or "12V battery charging system malfunction" message (i-FORCE MAX)

On the i-FORCE MAX the message that scares people most is often the small battery. The 12 V auxiliary battery runs the computers; when it is weak the truck throws hybrid system and charging warnings. Toyota also issued bulletins in 2023 for poor acceleration with certain codes and for control module processor codes P060649 and P060694. No recall has targeted the hybrid battery itself.

Safety: If the truck will not enter Ready mode on the road, it will not move. Have it towed rather than repeatedly cycling the power button.
  1. Test the 12 V battery
    Load test or at least measure the 12 V battery; a reading under about 12.4 V at rest, or a truck that sat for weeks, explains most of these messages. Charge it fully and clear the codes before anything else.
    easy$
  2. Read the hybrid codes
    A scanner that reads Toyota hybrid modules will show whether the fault is in the inverter, the battery ECU or a module processor (P0606 family). Toyota bulletins TSB-0030-23, T-SB-0046-23 and TSB004623 covered those codes with software updates on 2022–2023 trucks.
    medium$
  3. Warranty
    The hybrid components carry Toyota's 8 year/100,000 mile hybrid system warranty and the hybrid battery 10 years/150,000 miles. Anything beyond the 12 V battery belongs at a dealer.

Body & ElectricalRear camera image missing or wrong, blank instrument cluster, or the multimedia screen reboots

Five recalls and several bulletins cover the 3rd gen Tundra's screens. The rear camera image not displaying is recall 25V657 (multimedia software) and, for 2024 trucks with the panoramic monitor, 26V038; earlier camera recalls were 22V285 and 22V501. A blank gauge cluster on 2022–2023 trucks is recall 23V111. Reboots, black screens and CarPlay drops are bulletin T-SB-0012-24 and its software versions.

Safety: A rear camera that fails to show is a federal safety requirement issue, which is why it is a recall and not a bulletin; get it done.
  1. VIN check
    Run the VIN for 25V657, 26V038, 22V285, 22V501 and 23V111. All are software updates done free at a dealer, some over the air.
    easy$
  2. Soft reset the head unit
    Hold the volume knob about 10 seconds to restart the multimedia unit. For a reboot loop, owners report deleting the driver profile in the Toyota app and then doing a factory reset from the settings menu.
    easy$
  3. Software version
    Ask the dealer to confirm the multimedia software is current; T-SB-0012-24 (2024) applied versions 2050 and 2170 to 2022 trucks for reboots, blank screens, flicker after a text and CarPlay and Bluetooth problems. 2023 trucks had their own bulletin.
    easy$
  4. Hardware
    A head unit that still fails after updates is replaced under the basic warranty. Out of warranty, used units must be programmed to the VIN and new ones are very expensive, so exhaust the software route first.

DrivetrainVibration or clunk from the rear, gear oil on a rear wheel, or a loose rear axle (2022 recall)

Recall 22V445 covered 2022 Tundras whose rear axle shaft flange nuts could loosen and let the axle shaft separate from the housing. Toyota inspects and retightens or replaces damaged parts. Gear oil at the differential nose on later trucks is a pinion seal, the subject of tech tip T-TT-0706-22.

Safety: A separating rear axle can cause a loss of control. A new rear vibration or a wet hub on a 2022 is a stop-and-check item.
  1. VIN check
    Confirm 22V445 was completed. Even if it was, a rear vibration that starts suddenly deserves a look at the flange nuts and hub.
    easy$
  2. Look for leaks
    Gear oil on the inside of a rear wheel is an axle seal; oil on the differential nose and driveshaft is the pinion seal. Both are warranty items on a truck this new.
    easy$
  3. Rule out tires and the driveshaft
    A vibration that scales with speed and not engine load is tires or the driveshaft. 2024 trucks had recall 24V767 for tire sidewall damage; check the inner sidewalls.
    easy$

Body & ElectricalFuel smell, brake line chafe, or reverse lights with moisture inside (open recalls)

Two recalls on 2022–2025 trucks are easy to miss. 23V566 adds protection where a plastic fuel tube can rub on the brake lines on 2022–2023 trucks; a fuel smell under the truck is the warning. 25V322 replaces both reverse light assemblies and repairs the harness on 2022–2025 trucks with moisture inside the lamps. 22V661 reprogrammed the skid control ECU after it falsely detected an overcurrent and left the electronic parking brake unable to engage.

  1. Run the VIN for all open recalls
    The 3rd gen has accumulated more than a dozen campaigns, several phased by production date. One lookup at nhtsa.gov/recalls lists every open one.
    easy$
  2. Fuel smell
    Look along the frame where the fuel lines and brake lines run together. Any chafe mark or wet spot is a dealer visit, recall or not.
    easy$
  3. Reverse lights
    Condensation or water inside the lamp is the recall. Do not drill a drain hole; the harness is part of the repair.

EngineTinny rattle under the truck on cold starts or at a certain rpm

A thin metallic buzz from under the truck that changes with engine speed and goes away when you tap the exhaust is a catalytic converter or exhaust heat shield, a common owner complaint on these trucks. It sounds alarming and costs almost nothing. The job is telling it apart from a turbo wastegate rattle up top and anything from the engine itself.

  1. Find it with the engine running
    Have a helper hold the rpm where it rattles while you (safely) reach under and press on each heat shield. The noise stops when you touch the right one.
    easy$
  2. Fix
    A large stainless hose clamp around the shield, or a dealer tack weld, ends it. Dealers will do it under the basic warranty.
    easy$
  3. If it is not a shield
    A rattle from the top of the engine at idle is the wastegate symptom; a knock that gets louder with load is the main bearing recall. Neither should be ignored.
