2021 Toyota Tacoma

Engine developed a loud knock while under normal driving conditions at 61,000 miles. Oil was changed every 5k miles since new. Dealer says my oil rings on piston skirt have failed and heavy scoring on cylinder #5 Replaced short block under my aftermarket warranty. Toyota refused to cover it because I was 1k miles over factory warranty

Driving in town 30 to 40mph, (while in drive) the vehicle rev’d up like it was in neutral then went back to normal. That is concerning because it will cause transmission problems & pulling onto a road the truck could shift to (neutral) causing it to not go.

The cabin air pressure vents behind the back seat are leaking letting water into the vehicle. The seals have dried up. It's causing a moldy smell in the vehicle.

Having two issues major issues that’s causing me a $10,000 bill. The timing cover is leaking and there is a coolant bypass hose that is leaking. I have spend a lot of maintenance on this truck on maintaining it to have to remove the engine. As for the forward collision warning ive had it go off multiple times witout a vehicle there. While in cruise control ive had it unexpectedly break on me when there was no visible vehicle infront or next to me.

Brake master cylinder is leaking in the interior of truck on driver side floor mat. Oil is come from brake master cylinder seal.

The Multi-Information Display (MID) on the instrument cluster (combination meter) has failed completely. The display shows full-width horizontal RGB scan lines across the entire screen with no readable information. The analog gauges (speedometer and tachometer) remain functional but all digital display information is unavailable including speed, warnings, fuel economy data, and safety system status indicators. This failure occurred suddenly with no prior warning. Vehicle has approximately 50,000 miles. I am aware that Toyota issued Safety Recall 25V595 in September 2025 covering the identical combination meter failure on 2023-2025 model year Tacomas and other Toyota vehicles. The root cause identified in that recall — accelerated deterioration of the memory device inside the combination meter due to improper programming — appears to be the same failure mechanism present in my 2021 model year vehicle. I am filing this complaint to formally document that this known defect extends to 2021 model year Tacoma vehicles and to request that NHTSA investigate expanding recall 25V595 to include earlier model years. Toyota should be required to repair or replace the combination meter on affected 2021 vehicles at no cost to owners, consistent with the remedy already established for 2023-2025 vehicles. A Toyota case has been opened with the Brand Engagement Center at [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

About a month ago the Blind spot monitoring system failed, dealer said $2500.00 to repair, about 10 days ago, backup sonar parking system failed, dealer cost to repair $2200.00

The plastic coolant crossover valve or pipe failed at 66,000 miles and 5 years of usage. This led to the radiator cracking. After researching online, I read about thousands of Tacoma 3rd generation users with the same issue. Also, the same issue was recalled for several other models of Toyotas but not the Tacoma.

After I purchased my 2021 Toyota Tacoma TRD Sport with 4 miles on it and at 1,332 miles on 11/26/21, the Check Engine light with Traction Control Off light came on while I was driving. I immediately pulled over and on the truck media screen it read this: "A malfunction in the electronic control of the engine, throttle or automatic transmission has been detected. Contact your Toyota dealer and have your vehicle inspected." The truck was rough idling and had no acceleration. I had the truck towed to dealership where it was purchased and upon diagnostic, it was determined that #3-cylinder injector was reading "Open Circuit" with code P020313. Being under warranty the dealership repaired the bad injector. No further issues until 4/22/26. On 4/22/26 with mileage at 48,361, I started my truck in my driveway and immediately recognized that the truck was rough idling and the Check Engine Light along with the Traction Control Light Off being on. The exact same message displayed on the screen as above, "A malfunction in the electronic control of the engine, throttle or automatic transmission has been detected. Contact your Toyota dealer and have your vehicle inspected.". The truck was towed back to the same dealership and upon diagnostic the same issue of #3-cylinder injector "open circuit" with code P020313 was revealed. It was recommended to replace the bad #3-cylinder injector and also recommended to go ahead and replace all of the spark plugs. The total repair bill we be ~$2600 whe

When I push the brake pedal, it goes to the floor. I have had the brakes and master cylinder replaced. after about one month the brakes started failing again. I am going to take it back to the mechanic to have them re-evaluate the brakes. No kind of official has inspected my truck. I have been having braking issues for about a year.

There are three concerns in this write up: at 117000 miles the blind spot monitoring system has fails and will cost $300 to repair. More concerning is that it was recommended I replace the Power Steering Lines at a cost of $927 and the Transmission Lines at a cost of $797 due to severe rusting and corrosion. Its recommended before they rust through and break/leak.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The "coolant bypass hose/joint" (Part #: 16356-31051) located at the rear of the engine, connecting the two heads, failed. This part is made of plastic and is known to be a weak point in the 3.5L V6 (2GR-FKS) engine. The failed component is still in the vehicle and can be inspected upon request. 2. How was your safety or the safety of others put at risk? A coolant leak from this component can lead to engine overheating, which could cause sudden engine failure while driving, increasing the risk of an accident. Since the leak is not easily visible under the hood, a driver may not notice the issue until significant overheating occurs, potentially leaving them stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by the dealership after an inspection. They identified the coolant bypass hose/joint as the source of the leak. Many users on the forum TacomaWorld have also experienced the same issue with their vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by the dealership, but it has not been inspected by Toyota directly, the police, or an insurance representative. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first a

2021 Toyota Tacoma OR coolant bypass joint leaks at only 47800 miles. The cost of repair is $1490.36

When stopping vehicle (for instance, at a stop light), vehicle would stop normally when pressing the brakes, but after a few seconds, the vehicle would start forward again. The brake pedal would give way and press down further, stopping briefly before starting forward again - so I had to use the emergency brake or else vehicle would move into oncoming traffic. I consulted a mechanic, and it was diagnosed as a bad brake master cylinder. This vehicle has only 51,000 miles on it, being a 2021 model. The brake pads themselves were checked and they are fine. I replaced the master cylinder and it fixed the issue, but I wouldn't expect this unsafe condition to already be happening to this vehicle, especially this early in life. Toyota must have defective brake master cylinders.

This vehicle stalled while driving. It would totally shut off. Once at 75 mph no warning just shut off. Had a cylinder misfire according to dealership. On 2 other occasions it shut off while driving. On those occasions I was backing up out of a driveway and driving slow on a drive. So very slow speeds. On those 2 occasions it had engine stall codes according to dealership. I filed a lemon law claim and because it didn’t stall in the 58 miles the tech drove it Tamara Clear from gulf states determined there’s no evidence it stalls despite the local Toyota dealership having stall codes in their notes. Tamara clear also didn’t comply with Arkansas lemon law and respond within 40 days. She took longer because she’s overwhelmed with cases according to her. Each time the vehicle totally shut off while driving it had master warning lights, charging system lights, oil fluid temp lights, all of it. I took pics but Toyota didn’t care about that either Potentially fatal. And they expected me to drive around with a 6 year old in it

Toyota addressed this issue with the frame paint peeling off long ago but they have not launched a customer support program to solve the problem yet. When we reached their Brand Engagement center line (1-888-270-9371) and they do not provide a hard or estimated date to launch the repair program. The vehicle was already inspected by Round Rock Tx Toyota service (PDF page) certifying the issue is a manufacturer responsibility. Please take care of this situation promptly.

The contact owns a 2021 Toyota Tacoma. The contact stated while driving at an undisclosed speed, the vehicle lost power steering functionality. The vehicle was driven to the destination. The contact checked the power steering fluid reservoir and discovered that the power steering fluid reservoir was empty. In addition, the contact became aware that the rubber boots on each side of the power steering rack were soaked with power steering fluid. The vehicle was taken to the dealer where it was diagnosed with steering rack failure. The contact was informed that the steering rack needed to be replaced. The vehicle was not repaired.

I was idling in line for food when I noticed my thermostat gauge going slightly higher in temp. All of a sudden I hear a loud hissing sound and smoke coming off of the engine as well as a chemical burn smell. I pulled over to the side in fear that a fire could potentially start. After some research I’ve concluded that it is the rear coolant bypass joint. It was a high stress situation where my family was in my vehicle. Please look into this!

My vehicle was hit on the door frame and rear door on the driver's side by someone who ran a red light.

The cabin vent system appears to have a design defect, specifically the passenger-side vent located in the back of the cabin. This component is available for inspection upon request. The dealership, Santa Cruz Toyota, has declined to replace the part despite acknowledging the issue. The concern lies in the vent's design, as it allows water to enter the cabin instead of just expelling air. The water intrusion caused by this malfunction poses a safety risk in two ways. First, the presence of water on the floor increases the chance of an electrical fire due to the numerous electrical wires running underneath. Second, mildew spores can grow on the wet undercarpet padding, creating a health hazard. This problem has been confirmed by Santa Cruz Toyota, and we have video evidence to support the claim. While Santa Cruz Toyota has inspected the vehicle, our request for a direct inspection from the manufacturer, Toyota, has not been successful. There weren't any warning lights or messages prior to the failure. However, the issue became apparent after the heavy rains of 2023 in California, when we discovered water accumulated under the passenger-side carpet padding.

Rear spring excessive wear at 66,000 miles and needed to be replaced. Both sides worn but left more than the right

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.

Firestone Destination Le2 P245/75R16 On February 20, 2021 just 15 days after I purchased my brand new truck the rear passenger side tire dramatically exploded while I was driving in to my neighborhood. I was traveling at approximately 35 mph when out of nowhere a sound similar to a shotgun interrupted my driving and immediately forced me off the road in between two trees. I was narrowly missed by oncoming traffic and scared for my life. My side step of my brand new car was damaged as well as the rim and driver side wheel well where my car brushed the tree. I called Toyota and they said I didn't have tire coverage so I called my insurance company next. USAA sent a tow truck to pick up the vehicle and they brought it to Tire Choice. The associate said the tires were known for exploding and indicated that I needed to at least replace the damaged one and the driver side front for my own safety. The associate also said he didn't think these specific tires were even in circulation anymore. I went to Toyota and they said this was a manufacturers issue. No one was able to help me and I was forced to replace two brand new tires out of pocket. I was lucky I was in the neighborhood and not the interstate. There was absolutely no sign this was going to happen nor did I hit anything in the short time I had the car before the accident.

The paint is starting to peel on the passenger fender. It is on the inside of where the hood gap is in a area that is not exposed to rock chips or would be susceptible to external damage. It is also located right next to where the rubber bump stop is to prevent the hood from contacting the fender so it would be impossible for the hood to cause the issue and since the hood has no signs of chipping or rubbing in that area.

While driving on a freeway I step down on the as needed I got a message on my dash board that my braking power is low Stop in a safe place and see Owen's manual, A few seconds later I lost my brakes I have to use my hand brak to stop, came to a complete stop and called a tow truck, upon arrival the tow truck driver inspected my truck and realized there were brake fluid leaking out of my back drum, I took it in for a check up and I was told that my brake fluid is coming out of my braking cylinder, I checked for a recall I don't see it for my truck year but see it a the truck that's a few year older.

High-pressure and low pressure fuel pumps. Yes it is available for inspection. The truck cannot maintain posted, speed limit, causing a potential rear end collision. I reported the problem they replaced the high-pressure fuel pump for free and then said the low pressure fuel pump needs replaced the truck only has 40,000 miles. I think there’s a defect in this part that could cause lots of accidents. Check engine light is flashing and the ATC light comes on, the engine starts to sputter and cannot maintain speed.

I was about to park. press the break pedal in order to move gear to Parking. However, My Tacoma accelerated and I was unable to control it. Finally, it stop after hitting a tree.

Could feel and hear the front passenger seat (including the supplemental restraint system airbag) and seat belt move side to side and making a noise. I took the vehicle to Toyota of Denton, in Denton Texas for evaluation. Here is what they found from the service manager's email "Yours will need the seat frame replaced. The seat was removed, we found the seat track has play in it and is non serviceable meaning it comes as an assembly and you can not get individual parts for it. The estimate is $2234.28 and the part would take 3-4 weeks to come in as it is on back order. Keep in mind, that time can change along the way, but that is the current ETA. If you want to proceed with the repair, you would need to pre pay for the part and the diagnostic. The total repair would be reduced by the amount prepaid. I did reach out to Toyota and there would be no goodwill offered for this repair. It was just purchased and the selling dealer is who I would recommend you ask them for assistance. Please let me know how you would like to proceed." This same type of issue is found on from multiple owners. How many passenger seat frames have been replaced on 2019-2023 Tacomas, thousands? This is a huge safety issue effecting the safety of the seatbelt and airbag of the front passenger occupant. What is worse TOYOTA Motor Corp. refuses to honor their own SRS fully transferable 5 year - 60,000 mile warranties. leaving owners of these vehicles to pay for the cost on their own or worse driving a vehicl

The contact owns a 2021 Toyota Tacoma. The contact stated that while driving at unknown speeds, the brake message and alarm were displayed on the infotainment screen. While driving, the blind spot warning light illuminated, and the brake seized. The contact stated that the vehicle was pulling to the left. While driving and depressing the brake pedal, the vehicle was slow to respond. The vehicle was taken to the local dealer, who was unable to duplicate the failure, but the contact was informed there was a code for a caliper malfunction. The vehicle was not repaired. The manufacturer was contacted, and a case was started; however, no assistance was provided. The failure mileage was approximately 1,200.

Auto Emergency Braking has gotten extremely dangerous and locking breaks when nothing is in front of me. Always while in cruise control mode. On long extended highways, the truck will randomly slam on the brakes and skid the back tires. It has happened 6 times now. This most recent one made us slide into the next lane and I had to turn the truck into a field (~20mph) after the truck brakes went off. To avoid on coming traffic. There was a car turning around half a mile ahead and was nowhere close. Additionally, a severe issue of premature rust and degradation is occurring on the truck. 13,000 miles and the bottom looks like it's been on the road for several years.

My vehicle stalls (won't accelerate and rough idle) forcing you to roll off the highway without warning. This has happened multiple times while in cruise control going up steep hills. It shows engine misfire and check engine. I took it to the dealer multiple times and it was determined to be bad gas. I and my insurance company paid for this dealer (Hatch Toyota Show Low AZ) for complete clean and replacement of the entire fuel system. Now 5 months later it is doing it again. The safety issue is the stalling in the middle of the highway where there is no way to get out of the way of traffic. I made sure I bought good gas by paying extra money at a new Chevron gas station with new in ground tanks. But dealer claims bad gas again. That is a separate issue.

I went to my regular Maintenace appt at my local Toyota dealer Newton, NJ on 3/10/2023. They told me that it would be about $700 or more for my 2021 Toyota Tacoma boot leak and an alignment. I was told that it was due me hitting potholes. I did not agree with their opinion, and i was annoyed. They acted weird as well. But i told them to fix it anyway. So they ordered the parts. Much later they said boot leak was under warranty, but just to pay for alignment. I was not happy with the pothole accusation. Thank God the boot leak was covered! I have been taking in my Toyota Tacoma in every 5,000-6,500 miles as suggested. Please keep me informed of any recalls. They fixed boot and alignment on March 15 2023.

Defect in windshield consisting of thousands of tiny bubbles in the laminate which cause the windshield to become slightly opaque in direct sunlight or bright oncoming headlights. Dealer insists this is rock strikes. Toyota says the windshield is out of warranty. This defect began to appear at about 40,000 miles and is getting worse. (Vehicle is now at 54,000 mi.) I have seen other Toyotas (a RAV4 for one) with this defect. A definite safety issue, especially in bright sunlight.

The subject vehicle left roadway and impacted a tree in a pure frontal impact. The front seat passenger airbag failed to deploy. An 11 year old child was seated and properly belted in the front passenger seat. The child was killed as a result of blunt force trauma to his head when his head struck the front dash structure. In addition, the belted occupant seated behind the front passenger seat, while properly belted, impacted the rear of the front passenger seat and the seat deformed forward, limiting the ride down space for the front passenger seat occupant. The other three occupants in the subject Toyota Tacoma suffered non-life threatening injuries.

- Engine throttle went into wide open throttle causing the Unintended acceleration in traffic - The truck was doing about 45mph the passing gear came on and a second I was doing 60mph I quickly applied full pressure on the brakes and the car did not slow down at all, the truck failed to STOP or slow down and was getting closer to the vehicle in front, it was in the Expressway. My only thought was too press the ON OFF button and instantly shut down the passing gear and slowed down. _ The vehicle was dropped of at the dealer for 2-weeks and was inspected no problem found. - There were no warning lamps messages on the screen or voice message at all. I am afraid to drive this vehicle it became a runaway wild horse. If I didn`t react in milliseconds i would of hit the car in front at a high rate of speed causing damage to everyone. I took pictures after right after having full control of the truck. All the record of my complaints of the Tacomas drive train started more than 1 1/2 years ago the records are the facts of Toyotas negligence. I have total fear and don`t trust this truck with my life. Please check the recorded dealer is Doral Toyota and you can speak with the Service manager [XXX].
