2020 Toyota Tacoma Complaints

UNKNOWN OR OTHER — Filed 03/07/2026

I am reporting a safety-related failure of an aftermarket bull bar / grille guard purchased through Amazon. The bull bar detached from the vehicle while the vehicle was in motion on a public road. After detaching, the bar was dragged on the road and was only partially held by the fog light wiring. This created a road hazard and could have caused loss of control, damage to other vehicles, or injury to pedestrians or other drivers. The failure appears to be at or near the welded joint / mounting area, suggesting a possible manufacturing or weld defect rather than normal wear. The product was installed on the vehicle before the incident and failed during normal driving. Product: - Product type: Aftermarket bull bar / grille guard - Brand / seller: Topline_autopart / Amazon - Purchased from: Amazon - Order number: 114-8975268-2481806 - Purchase date: November 21, 2025 Vehicle: - Year / Make / Model: 2020 Toyota Tacoma - Incident date: Mar. 7th 2026 - Approximate speed: 45mph - Location: Exit 111 at I-16 EB I have photos of the failed weld / mounting area, the damaged bull bar, and Amazon order information. I am concerned that other units of this product may have the same defect and could detach while driving.

VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM — Filed 03/15/2026

On Sunday, March 15,2026, I was driving from Houston, TX to Pharr, TX at the speed of 75mph on the left lane to pass an 18 wheeler, with another 18 wheeler behind me, and my truck started idling erratically. I lost speed and my service engine light came on. My truck slowed down and I almost got in a car accident with the 18 wheelers because the truck did this. The truck behind me slowed down on time and it went immediately to the right lane to avoid hitting my truck. I feared for my life. All the vehicles behind me and the 18 wheelers also went to the right lane to avoid me. By this time, the TRAC light had already come on also. I managed a space of no vehicles and steered towards the right safety lane. I pulled over at the local truck stop and stoped my truck to rest. After about 5 minutes I tried starting my truck and it wasn’t starting. I am a little mechanically inclined, so I started troubleshooting the truck. My code reader gave these codes: P1605-00, P0300-27, P0300-85, and P0302-00. Unscathed to start the truck after a while and got back on the road. The drive was brutal, as the truck kept burping erratically, but I made it home safely. I took my truck to the mechanic and he did some repairs and told me the issue is the fuel pump. I have checked the recalls for my truck but it shows zero recalls for my truck. Luckily I am alive to report this life threatening safety issue that Toyota has on this model. How do I get Toyota responsible to make the repairs on my truck? The part alone is over 1200 at O’Reily auto parts.

POWER TRAIN,ENGINE,FORWARD COLLISION AVOIDANCE — Filed 01/17/2026

Toyota has a manufacturing defect going on with their v6 in Gen 3Tacoma's. I have a 2020 Limited with 48,200 miles that needs a new cylinder head. It threw a check engine light on me, and luckily enough I took it to the dealership within about 30 miles, otherwise my engine could have exploded. I have videos from the dealership inspection that I cannot attach here. I have since found via the error code a history of these issues on newer trucks. [XXX] [XXX] [XXX] [XXX] [XXX] [XXX] I believe that this issue could pose serious safety issues for someone who is not as immediate on stopping driving, as it was just a check engine light. If you were to drive on this light down the highway, and have catastrophic failure, the Tacoma becomes a completely unpowered hazard.

The concern involves the automatic transmission torque converter, specifically torque-converter lock-up behavior. The issue presents as a vibration/shudder during steady-speed driving. The vehicle remains in my possession and is available for inspection upon request. The vibration/shudder occurs during steady cruising at moderate speeds, which affects vehicle smoothness and driver confidence. While no accident occurred, the behavior is unexpected and distracting and could impact safe vehicle operation, particularly during highway driving or when maintaining steady speed in traffic. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The concern has been reported to and evaluated by a Toyota dealership. Diagnostic checks did not produce fault codes, but the symptoms are consistent with torque-converter lock-up issues that occur without triggering warning lights or diagnostic trouble codes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by a Toyota dealership service department. It has not been inspected by police or insurance representatives, as no accident or collision occurred. Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear? No warning lights or messages were displayed. The primary symptom was a noticeable vibration/shudder during steady-speed driving, which began after the vehicle was purchased in July and after routine dealer-performed maintenance. The condition developed without advance warning indicators.

Vehicle accelerated on its own at highway speed, had to hit the brake in order for it to stop accelerating. Other more common issue is that vehicle RPMs go up when trying to accelerate but vehicle does not accelerate, just RPMs go up. This happened about 5 times over the past year and a half. Most noticeable time was where I couldn’t accelerate after at all until I pulled over and put it in park. Then back to drive again and worked fine. This car has been brought over to Lia Toyota of rockland numerous times with this second issue and they can never duplicate nor fix the problem
