What’s Behind Toyota’s “Bullet-Proof” Reliability Reputation?

A manufacturing defect in certain V35A engines is a serious Toyota reliability concern, but the recalls affect specific vehicles—not the entire lineup.

The clearest documented threat to Toyota’s reliability reputation is a manufacturing defect in certain V35A engines: machining debris can contribute to main-bearing failure, an engine stall and loss of drive power. The recalls affect specific Toyota and Lexus vehicles—not every Toyota—and do not establish that the brand’s reliability is collapsing.

What defect is behind the concern?

NHTSA’s November 2025 notice for campaign 25V767 says manufacturing debris may contaminate certain V35A engines and cause their main bearings to fail. The agency describes the possible result as an engine stall and loss of drive power. The notice lists 126,691 potentially affected vehicles, including specified 2022–2024 Toyota Tundras, 2022–2024 Lexus LX vehicles and 2024 Lexus GX vehicles. NHTSA’s campaign notice defines the covered population; a Toyota or Lexus badge alone does not establish eligibility.

In May 2026, NHTSA recorded campaign 26V320, an expansion covering certain 2024 Tundras and listing 43,566 potentially affected vehicles. The remedy was under development when that notice was filed. These figures belong to separate campaign notices and should not be added together as a total without evidence that their vehicle populations do not overlap. The expansion notice provides its campaign details.

Which vehicles and repairs are involved?

The campaigns differ in scope and timing. Toyota’s May 2024 materials for campaign 24TA07/24TB07 covered approximately 98,600 specified 2022–2023 Tundras and described engine assembly replacement at no charge. That remedy description applies to that campaign; it should not be assumed to describe the status of later campaigns. Toyota’s 2024 recall materials also list possible symptoms: engine knocking, rough running, failure to start or loss of motive power.

Eligibility and repair instructions depend on the individual vehicle and campaign. Check the VIN rather than relying on the model name, model year alone or a general list of affected vehicles. If a vehicle is included, follow Toyota’s current instructions for that VIN.

How to check whether a Toyota has an open recall

  1. Find the vehicle identification number (VIN), usually visible at the lower driver-side windshield or on the driver-side door label.
  2. Enter it in NHTSA’s recall search to look for unrepaired recalls. Toyota also provides a VIN lookup in its recall information.
  3. If a recall appears, contact a Toyota dealer and follow the instructions for that campaign. Confirm the current remedy and appointment details directly with Toyota or the dealer.

NHTSA says a recall does not expire, and owners can use its VIN search to check for unrepaired recalls. A search result for one campaign does not determine whether a different vehicle is eligible; use the VIN-specific results.

Does one major recall mean Toyota reliability is collapsing?

No. A safety recall documents a defect and the vehicles potentially affected by it; it does not measure the reliability of every model or prove a brand-wide trend. Likewise, a reliability survey reports owner experiences under its methodology and is not a record of safety defects.

The distinction matters here. The Associated Press reported that Consumer Reports’ 2024 subscriber survey ranked Subaru first, followed by Lexus and Toyota, and that the RAV4 and Corolla were among its highest-rated models. The survey represented about 300,000 vehicle owners, but Consumer Reports cautioned that subscribers do not represent all vehicle purchasers. Those findings offer context, not a 2026 ranking or proof that Toyota has—or has not—declined over time. The AP report explains the survey results and limitation.

Is complexity the cause?

Commentary has proposed that increasingly complex vehicle technology may be contributing to reliability problems across automakers. That is a broader interpretation, not the defect explanation in these Toyota recall notices. NHTSA’s notices identify manufacturing debris as the stated issue; they do not establish that complexity, emissions rules or a particular management decision caused it. Autoblog advanced a complexity thesis in a September 21, 2026 article, but that framing is not a substitute for the campaign records.

The defensible conclusion is narrower: a serious manufacturing-quality problem in specified V35A engines can threaten confidence in Toyota’s reputation, especially for owners of affected vehicles. The available recall and survey evidence does not show a single cause for a Toyota-wide reliability decline.
