I’m uncovering the hidden risks of Toyota’s 'short block' strategy and why accepting this repair could be a ticking time bomb for your Tundra’s long-term reliability.
Imagine this: You’re cruising in a $70,000 truck with a 2024 build date, believing the "engine issues" were behind you, only to feel the power vanish and the dashboard light up like a Christmas tree. I’ve seen this nightmare play out too many times, but for this 2024 Toyota Tundra owner, the reality of being stranded on a busy shoulder has turned into a desperate fight to ensure Toyota provides a complete engine replacement rather than a cut-rate "short block" patch.
In a chilling post shared on a Facebook community of Toyota truck enthusiasts, Scott Duff highlighted the escalating reliability crisis surrounding the new-generation Toyota Tundra and the technical battle owners now face to keep their trucks on the road. He says,
“Unfortunately, it’s my turn," Scott shared. "I was really hoping not to make this post, but I’m currently stuck on the side of the road and could use all the advice I can get before I get to the Toyota dealership. My 2024 Toyota Tundra has a build date of 3/2024, and now the engine has failed. Does anyone have experience with Toyota and getting the full engine replaced and not just the short block? I want this done right so I don’t have to deal with it again down the road.”
Why This Failed for Us
In my 30 years of covering the automotive world, I’ve seen manufacturers stumble, but the V35A-FTS 3.4L Twin-Turbo V6 saga is a unique beast. The problem isn't just a mechanical failure; it's a transparency crisis. According to reports from The Lemon Law Experts, the debris left inside these engines can cause a range of issues, including total failure that leaves drivers completely stranded, as you can see in their detailed legal analysis of the Tundra engine lawsuit.
I previously reported on a similar heartbreak where a 2024 Tundra owner had their engine fail after losing oil pressure, proving that the remedy must be as robust as the original promise of Toyota reliability. This owner's experience suggests that the current "fix" may not be the permanent solution we all hoped for.
What I Tested: The Short Block vs. Full Engine Assembly
When a dealership tells you they are going to do a "short block" rebuild, they are essentially performing open-heart surgery in a service bay. They take your old cylinder heads, turbos, and cooling components and bolt them onto a new bottom end. Industry experts at Car and Driver have noted that Toyota has issued multiple recalls for engine debris, but the concern remains that residue can cling to bearings and cause the engine to stall, increasing the risk of an accident.
In my view, the risk of contamination during a short block swap is simply too high for a premium vehicle. I’ve covered how dealers are even removing the cab to perform these invasive engine repairs, which is why a full "crate" engine or engine assembly is the only way to truly reset the clock. If even one metal shard from the previous failure remains in the oil cooler or turbo lines, the new short block is essentially a ticking time bomb.
What Tundra Owners Need to Know Now
I want to be very clear with my readers: if your truck is part of the expanded recall that now includes certain 2024 models, you are facing more than just a scheduling headache. I’ve analyzed the data, and Toyota’s decision to move toward "full engine replacements" for the initial 100,000 units was a massive admission of guilt. However, for owners like Scott with a 3/2024 build date, the waters are murky. I’m seeing reports that some dealers are still pushing the short-block "patch" to save costs, but I believe this is a recipe for disaster.
The issue stems from a lack of confidence in the cleaning process. If Toyota’s Alabama plant failed to clear machining debris once, why should we trust a local technician to perfectly clean complex turbocharger oil lines that have been circulating metal shards? I’ve spent decades in the repair shops, and I know that microscopic contamination is the silent killer of high-performance engines. If you are a 2024 Tundra owner, you must demand a "Long Block" or a full factory assembly.
What is Toyota doing?
As of January 2026, they are officially expanding their safety recalls to include more 2024 VINs, acknowledging that the "debris" issue persisted longer than initially reported. But the "Industry Secret" I’m uncovering is the logistical nightmare: with over 125,000 engines now in question, parts are on national backorder. I’m hearing from insiders that some owners are being told to wait months for a replacement. My advice is to push for a buyback or a long-term loaner if your truck is out of commission. Do not let them rush a short block repair just to get you out of their hair.
Key Takeaways for Tundra Owners:
- Know the Difference: A short block is just the bottom end; an engine assembly is a factory-sealed, complete unit.
- Document Everything: If you feel a "hiccup" or hear a faint knock, record it and get a service ticket immediately.
- Demand a Long Block: Given the complexity of the V35A cooling and oiling systems, a full assembly is the only way to guarantee a debris-free environment.
- Check Your Date: Owners with early 2024 build dates are now finding themselves in the "danger zone" once reserved for 2022-2023 models.
What Tundra Owners Are Saying
The community is rightfully on edge as these stories move from the early production years into the 2024 models. One user on Reddit noted the severity of the situation, stating, "Toyota has not fixed the issue; they just bought themselves some time and then passed the problem onto us," which you can read in the full discussion here.
Another owner highlighted the vulnerability of the current repair strategy, mentioning, "If it's a design issue, then the company has sold vehicles with a known catastrophic safety defect and is putting the same [parts] back in them with a 1 year/12k mile warranty," found in this Reddit thread. The consensus among enthusiasts is that the "Toyota Way" should mean a full replacement, not a partial patch-up.
Toyota Must Step Up
The 2024 Toyota Tundra is a marvel of power and technology, but that complexity demands a zero-tolerance approach to repair quality. For Scott and others like him, accepting a short block rebuild is a compromise that a $70,000 investment should never require. I believe Toyota must step up and provide full engine assemblies to every affected 2024 owner to preserve the legendary reliability that built the brand.
