3.4 I-Force engine failures.

4 months at the dealership getting short block replaced, very next day it’s leaking what appears to be coolant. Dropped it back off after 1 day

 

Mileage that problem/failure happened:26,000 miles

2022 Platinum

-What actually happened: Traveling at highway speed and engine shut off. I was able to restart it with limited power and pull over to a parking lot. Dashboard showed 'check engine' and vehicle would not start. Towed to dealer. Dealer called the following day and confirmed the engine needs to be replaced.

-Vehicle usage (towing/off-roading/pavement pounder): City and highway use. Tow a 3500 trailer for camping.

-Vehicle modifications (tune/geared/tires): none / stock

Other previous issues: none. Vehicle serviced at the same dealer that completes the trucks normal service schedule.

 

Welp… it’s early in the process but just got the call from the master tech that I will be needing a new engine.

Mileage that problem/failure happened:40,000

2022 Platinum

-What actually happened: Traveling at highway speed and engine shut off. I was able to restart it and thought maybe I ran out of gas, it was low, but gas light wasn’t on yet. Wouldn’t start, waiting a couple minutes tried again and it started, drove to the nearest gas station, put about $20 in it (gas station was sketchy)
Pulled out and back onto the highway heading home. Acceleration felt slow, but nothing noticeably wrong. Took my exit and while idling at the light the truck sounded horrible and felt very rough. This next acceleration was awful and I called the dealer and told them I was heading that way. No engine lights, no alarms, just the initial “engine is stopped, find a safe place to pull over” or something like that.

-Vehicle usage (towing/off-roading/pavement pounder):Normal City and highway use. Have towed small camper and small boat in the past, but not in the last 10k ish.

-Vehicle modifications (tune/geared/tires): slightly bigger tires and a soft topper. That’s it.

Other previous issues: none. Vehicle serviced at the dealer during normal service schedule.

I am trying to lean towards a buy back if they try and just rebuild or replace. If anyone that has been through this can reach out and let me know their process, please let me know asap. THANK YOU!

 

2024 Toyota Sequoia Capstone, build Jan 2024. Catastrophic engine failure at 4,000 miles. 2" chunks metal in oil pan. Dealership tearing engine down still

 

1st post
I'm up in Vancouver Canada

2023 tundra hybrid limited
w/ TRD OFFROAD package

mileage: 36000km (22k miles)

build date: Jan 2023

What happened: rattling noises while on highway going 100km/h (62mph). Pulled over within a minute of the rattling noise.
When slowing down to a stop and at idle, it goes to a loud knock noise. Popped the hood and was extremely hot in the engine bay.
No current or previous problems. No signs or alerts or check engine light or temp light.

Vehicle use: Daily driver. Never towed, never offroaded. Rarely floored it. Never even engaged 4L

Vehicle mods: none. Everything stock/oem/original

Maintenance interval:Got the extended warranty so first few services were mandatory to be done at the dealer.
Followed their maintenance schedule. "service" every 8k km and oilchange every 16k km.

My vehicle at 36k km has gone for service 4x times and has 2x oil changes

Currently towed to the dealer and they are tearing it down to inspect the engine.
The service manager said this is their 3rd tundra they've had and the 1st that is a hybrid model.

I hope this whole thing gets resolved soon. Very frustrating.

 

2023 Tundra Limited

-Mileage that problem/failure happened: 44,852 on 7/17/24

-Build date: Unknown, but took delivery late-July, 2023.

-What actually happened: Drove for about 2 hours home on highway without a problem. Exited highway and heard engine knocking while at stop sign. Absolutely no indication prior to that. Was able to drive home (just down the street). Immediately could see oil dripping from engine. Checked the dipstick and it was full (ie engine hadn't been low, dealership confirmed).

-Vehicle usage (towing/off-roading/pavement pounder): Highway

-Vehicle modifications (tune/geared/tires): None

-Maintenance intervals: All <10k intervals per Toyota recommendations, had the 30k service done, too. All done at Toyota dealerships.

Toyota has said it needs a new engine. Estimating end of August, which would be about 6 weeks after failure.

Toyota is currently replacing the engine (including turbos) under warranty, NOT under recall. They're saying this truck was manufactured after February, so it's currently not under recall. I'd think they'd HOPE it's a recall issue - otherwise, they've two problems that are causing these engines to fail!

If it's under recall, they provide and pay for a rental car. As of now, I'm supposed to pay for the rental.

This is my 3rd Tundra. Other two were the 5.7L - drove to 250k+ and 200k+ with absolutely no problem. Currently also have a '19 Sequoia with the 5.7, no problems. Why oah why did they mess with near-perfection? 16 to 21 mpgs just doesn't seem worth these problems.

I sure hope Toyota does me right and pays for the rental. Until they tear it down they cannot claim it's an unrelated failure. Recalls are often expanded in timeframe, not condensed. Not only have I owned 6 Toyotas (4Runner and Highlander, too), but I've convinced a handful of other guys here in the Midwest to dump their domestics and move to Toyota. Toyota, I hope you're reading this...

 

To get as much information as possible if known: 2022 limited 4x4

-Mileage that problem/failure happened: 36500

-Build date: 07/2022

-What actually happened: Hard acceleration to pass someone up. Right as I passed the car a warning message popped up telling me my engine shut off and to pull over. Dealership diagnosed it as needing a new engine.

-Vehicle usage (towing/off-roading/pavement pounder): pavement pounder

-Vehicle modifications (tune/geared/tires): none

-Maintenance intervals: 10k oil. 5k tire rotation and other fluid checks.

 

-Mileage that problem/failure happened:28k

-Build date: not sure took delivery on 10/19/22

-What actually happened: Traveling to Minnesota from Colorado for vacation and to pick up new boat to bring back to Colorado. When I was about 100 miles away from Mankato, MN. I stoped for gas and when I started the truck after refueling I heard a ticking sound that would speed up and down with the throttle. The closest dealership was in Mankato,MN. I could not make it to them before they closed for the night. In the morning I started the truck so I could get to the dealership to take a look. When I was about 1 mile from the dealership I was going up a hill and gave some extra throttle and heard a big thud and warning lights and beeps and a prompt of low oil pressure and to pull over and shutdown vehicle. Was towed to dealership and was informed that they pulled the oil pan and there were chunks of metal in the pan. Dealership looked at the vehicle on 9/13/24. As of this post I have resolution on what can be done and I have fulll extended warranty purchased from dealer. I am currently on phone with Toyota Brand Engagement to see about shipping truck back to CO for repairs so I don’t have to fly or drive back to Mankato in few months. Also trying to get a resolution on a rental to get back to Colorado.

-Vehicle usage (towing/off-roading/pavement pounder): towing & payment pounder

-Vehicle modifications (tune/geared/tires):none

-Maintenance intervals every 5k as recommended by dealer

[EDIT: I rarely if ever post here, usually just lurk. But did a search as it's been one month and 2 days since I've had my Tundra, so wondering if I'll ever get it back. Dealer is just awful to deal with as it isn't their issue, but rather Toyota NA.]

Yep - 27k miles on my 2022 Tundra 4x4 TRD Off-road SR5. NOT the iForce hybrid engine, but the 6 cylinder twin turbo. Highway and around town miles. Never abused, always maintained at the dealer. Never towed with it. No modifications other than a tonneau cover and leather Katzkin seat covers.

It's been at the dealer a month now, and still no word on when they'll fix/replace it. Originally told by the service department rep that it'll be about a month - spoke with a mechanic afterward and he laughed. Told me 3 months minimum - seems like it might be longer.

When it started failing, I thought maybe there was a frayed belt as it was making these weird and random ticking sounds. It still ran okay and never entered "limp home" mode. Took it in, got the call the next day: "Your engine's failing."

Been driving a rental provided by Toyota for a month now (a Dodge Ram 1500) and I'm just sick of it. Super shitty truck. I want my Toyota back.
