I was informed by the service manager at labadie Toyota (bay city, mi) that the new 2. 4l turbos have injector issues! some sienna's Tacoma's, and other models have faulty direct injectors that spray way too much fuel into the cylinders, and it drains into the oil reservoir! I had my oil changed at 1k, 5k and 10k by the dealership. I've had this issue at 5k and I presumed service center incompetence, and they agreed. I recently had my oil changed at 10k and came back in 2 weeks later with check engine light on and excessive engine chatter. I was told this a known Toyota engineering issue, and they are now telling the techs to look into the cylinders to look for clean/washed piston tops. Today they just changed my oil and told me to come back in 3 weeks or if issues arise. I'm concerned about a fire with gas going into the engine oil and potentially causing a fire. Toyota engineering is aware of this issue I was told so I would a recall to be issued so there is no issues with a fire happening.

I purchased a brand-new 2025 Toyota Tacoma trd off-road. From the first day, the steering wheel was off-center and the vehicle vibrated while driving. At around 500 miles, I noticed severe instability and abnormal tire wear. A wheel alignment report showed: thrust angle: +0. 15° (spec: 0° ± 0. 05°) rear toe: left 0. 23°, right -0. 10° (difference: 0. 33°, spec ? 0. 15°) front caster: both sides out of specification (shown in red on report) driving symptoms include: cannot maintain straight-line driving; requires constant steering correction. Excessive body roll during lane changes or turns. Continuous vibration of the vehicle and steering wheel on smooth roads. Vehicle bounces and momentarily loses control on uneven surfaces. Steering wheel rotation does not match front wheel steering angle. When stationary, turning the steering to full lock causes the body to rise; releasing it causes it to drop. Attempts to repair at Toyota of manhattan (June 2025 – August 2025) were unsuccessful. The dealership repeatedly refused to perform proper inspections, provide reports, or acknowledge the defect, despite multiple appointments and a case opened with Toyota corporate. The defect presents a serious safety risk: reduced vehicle stability, increased stopping distance, loss of steering control during maneuvers, excessive and uneven tire wear, and abnormal fuel consumption (13. 5 mpg with no load). The problem exists from new and has not been corrected.

My check engine light came on when I was traveling in oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi. . . I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. They are saying it could be the 2nd cylinder or the engine and claiming it has 150,000 miles so I should expect these issues (and conveniently my warranty has run out).

Engine began making abnormal ticking noise, heard primarily on the passenger side of vehicle. Upon removal of valve cover for inspection, found that there are chunks of camshafts breaking off causing the noise. Appears to be a manufacturing defect. Local dealer said they have seen this issue before. This issue could result in catastrophic engine failure and/or loss of power and cause a crash. My truck has 70k miles on it, regularly maintained and operated.

Vehicle lurched forward with a “bang” accelerating in stop and go traffic. Vehicle then stalled and flashed multiple warnings. Hybrid system failure. Drive mode failure. General failure. Vehicle would not restart on first attempt - multiple attempts made to restart. Upon restarting, it would not move forward in drive, prompting a new error stating it needed to be returned to park. After a couple more restarts it was able to engage the gear and move forward. Power was limited, it drove differently, and the hybrid error persisted.

The timing chain cover is leaking oil which will render the vehicle inoperable which is a safety concern. The diagnosis was done at Toyota and I am being told to repair the truck already at 84,000 miles. The cost of the repair is astronomical ($6,666). The problem appears to be a gasket which to reach for repair requires dropping the engine. It is not fair that consumers bear this burden for faulty design linked directly to a safety concern (engine will stop working because of oil leak).

I started up my Toyota Tacoma early morning on [xxx] and noticed the engine light came on after it warmed up in the cold climate of northern arizona. As such, this occurred at 36,303 miles. The fault code stated the following: “a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer in order to have your vehicle inspected. ” later in the day, I scheduled an appointment for December 14, 2024 at anderson Toyota. I explained the situation and was disappointed to get an engine light so early, as it didn’t make any sense. Afterwards, at 8:47 pm from getting off work, I intuitively decided to check the engine compartment as the lady with the dealership claimed if rats chewed up the wires it wouldn’t be covered under warranty. Lo and behold, I didn’t find any wires chewed up, but I did find the engine oil filler cap wholly missing! I documented this incident with my camera phone in utter disgust, my initial assessment is Toyota failed to reinstall the oil filler cap. I called the next day, and left a voicemail expressing my disgust and disappointment in their service. Upon arrival, service advisor jennifer advised it is a known issue with the oem oil filler caps coming off. The dealership claims it wasn’t their tech, but a faulty part. Again, (1) this puts me in danger on the road with open contamination occurring to the point, where my engine light is now activated and (2) Toyota should issue a lifetime replacement warranty for any engine issues for the 22’ model Tacomas as the damage has occurred, regardless of what the dealership claims. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle fuel pump went out without any notice and fuel gauge and cluster not showing any data on the instrument cluster. Vehicle loss power and would not go over 40mph on the freeway take over 5 minutes to reach 60 mph per hour. Always serviced at the Toyota dealer and they won't help to fix the problem since its over 49k. They won't even look at emissions problem even it under warranty for 8 year/ 80k per emission warranty for ecu.

2021 Toyota Tacoma or coolant bypass joint leaks at only 47800 miles. The cost of repair is $1490. 36.

This vehicle thermostat and sensor system are faulty! my sensor started lighting up within a year and half after purchasing. Engine was not overheating at first, they said it will eventually happen and it did; all dealers said to replace but I was out of 360000 miles due to commute to seattle. This vehicle is less then 3 years old and should have this item listed specifically in power train warranty since connected to engine directly. If engine overheats it is no longer usable and truck is useless! engine warranty if this is a know issue from Toyota dealerships. Contacted 3-4 dealerships in the state of wa and all had known of issue. One dealer stated anything from 2020 to current has had thermostat issues. This is serious concern knowing the engine can seize up! their thermostat and sensor should not be a combined item in my opinion. Please advise and or confirm this is an issue that should be looked into. If the engine overheats then the vehicle could cause an accident! this is a huge safety risk that can be avoided! I work and make it from paycheck to paycheck this was very expensive to fix and had to paid out of pocket. Please help others be aware of situation!.

Rear coolant bypass joint leak. Coolant leaking through this pipe and accumulating.

The transmission cooling line in my 2019 Toyota Tacoma was never installed by an authorized repair shop following an accident. This critical component failure led to the transmission failing just 1. 5 hours after I retrieved the vehicle from the shop. My safety was compromised, as the failure occurred while driving at highway speeds, without any warning lights or messages indicating an issue. The failure has been confirmed by the dealership (motorworld Toyota) currently inspecting my vehicle. The shop responsible for the initial repairs has taken liability for missing the installation of the transmission cooling line. My insurance company (geico) has been involved but is delaying total loss consideration. No warning lamps or messages appeared before or after the transmission failure, which is highly suspicious. This negligence has caused severe damage to a vital component of my vehicle, and I question the overall integrity of the repairs.

Coolant leaking.

I have had my secondary air pump replaced twice already. Now six months later am having the same codes and the truck is back at the dealership. Throws code p2443 valve stuck closed. . . . . On a 6 month old part. This w=has been an issue with this and other Toyota models since 2012. Why is there no recall on these?.

Engine is noisy during take off sounds like a rod knock the truck has 5k miles on it.

While driving I received numerous system malfunction warnings followed by a message to visit my dealership. While driving into the dealership the vehicle started losing power and engine went into complete failure. It is now at dealership and waiting for it to be inspected. When alerts first went off I was unable to stop because I was on a busy dangerous street.

When stopped at stop signs or intersections ,when taken off from a stop truck would have a dead spot and almost caused a accident trying to get into traffic. Has happened several times over the lease time I have had it. No alerts. Has been reported . Gas treatment suggested. But still does it to a degree.

2017 Toyota Tacoma double cab-v6 with 62k approx miles. On or around April 29th 2024, I was traveling in this truck when there was a sudden and complete loss of power, two check engine lights came on-the "trac off" light and the check engine light came on. I needed to pull over immediately for safety. I ended up driving the vehicle to the Toyota dealership in limp mode. The vehicle has sat at tustin Toyota now for weeks with the Toyota dealership initially suggesting that a acis flap broke off inside the intake manifold of the car. This was replaced and the vehicle is still providing the same alarms and still in limp mode. The initial fix(whihc did not fix the problem was a full replacement of the intake manifold). Now the dealer is suggesting that a piece(s) broke off the intake manifold and ended up inside the engine so now dealer is recommending and entire engine break down to attempt to further diagnose the situation. Again it looks to be a complete failuure of the acis system and the intake manifold. This problem has presented a extreme safety issue due to comp[lete loss for power initially then truck sits in limp mode. Very dangerous!.

Upper intake manifold flap actuator ( part: Toyota 17190-0p101 ) brakes in the intake resulting in wrong air reading and forcing vehicle into limp mode causing the vehicle to rapidly decrease speed, and creating a potential accident with other vehicles and semi's. This will continue to happen but this will give a person a false sense of security since error codes will reset once vehicle is turned off and on, a reassurance to a person that the issue has resolved itself since this will only happen at high speeds. The part is designed for fuel efficiency, as the flap opens and closes air is controlled properly for emission, but once broken will throw error codes, and force vehicle into limp mode this part is not be repairable, the part needs to be changed completely. This would happen to me while accelerating on highways, up mountain passes and pushing vehicle over 4000 rpm.

Motor tensioner bearings. All of the motor tensioner bearings have completely failed on this vehicle at 70,000 miles. All have to be replaced in an effort to avoid motor seizure and or other grave safety issues.

Driving at approximately 55 mph and dash lights started flickering, radio went off, reset to 530 (am radio). Vehicle started sputtering and slowing down in traffic and completely shut down. Lost all power and coasted to side of road. I had no or little control of vehicle. I have "connected services" that was to warn me about mechanical and electrical failures and no warning of this happening. This enrollment was to give me "services designed to help keep you safe, secure and in control of your Tacoma from almost anywhere". "brand engagement center" not concerned of the incident. Apparently two and half year old battery failed. Replaced by myself.

The contact owns a 2023 Toyota Tacoma. The contact stated that while driving at approximately 15 mph and attempting to make a right turn, the check engine warning light illuminated, and the vehicle started jerking. The vehicle was taken to the dealer, where the contact was informed that the vehicle could not be diagnosed because the check engine warning light was not illuminated. The contact stated that the failure persisted. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 2,000.

Wiring harness on the vehicle is being completely replaced due to "rodent damage" according to the dealer. I am not an automotive engineer but if compromised wiring finally fails while driving I suspect a number of systems could be affected. There was no indication of this problem during vehicle operations. My insurance company agreed to pay for this about $7200. I have owned the vehicle for ten months.

Experienced a check engine light and took the 2019 Toyota Tacoma to the Toyota dealer where they ran diagnostic check revealing the # 1 cylinder had little to no compression due to damaged valves. Mileage at the time of failure was 59966 miles.

Rear coolant bypass joint leak. This is a plastic defective pipe that has leaked on my truck and thousands of others! the dealership wants 2000 dollars to repair their cheap mistake! I have pictures and invoice to upload, but the site will not allow it.
