The rear wheels on my 2016 Toyota Tacoma locked up as I was travelling straight at approx. 55 mph on the 110 North freeway during rush hour. The truck went into a fishtail which I was able to control and bring to a stop the dealer tells me the bolts on the rear differential came loose and the oil drained out causing the rear diff to seize and stop the tires from rotating. Truck has 12,500 miles on it and just a year old. No accident occurred so no report was filed. Chp was on the scene until a tow truck came to tow me off the highway.

The contact owns a 2016 Toyota Tacoma. While driving various speeds, the vehicle began to make an abnormally loud noise. The contact noticed that the transmission would shift between gears independently and the four wheel drive feature would not engage after being activated. The dealer diagnosed that the software failed for the transmission and needed to be updated. The vehicle was repaired, but the failure recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 325.

The contact owns a 2016 Toyota Tacoma. While driving approximately 40 to 65 mph, the vehicle randomly upshifted and/or downshifted and accelerated or decelerated on its own. There were no warning indicators illuminated. The vehicle was driven to the dealer and a software update was performed. The issue recurred numerous times. The vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 4,000.

-transmission is too quick to upshift causing the engine to bog down. -transmission causes the tuck to lurch forward at low speeds. -shifting from R to D on a hill can sometimes cause the truck to roll backwards as if the truck was in neutral -in general, the transmission is inconsistent in operation. In the same situation it may react differently -during hard acceleration after you let up on the gas, the engine RPM's will stay high and slowly come back down. If you press the gas again during this time the transmission will either cause the engine to rev but the truck won't accelerate, or will slam into a gear causing the truck to lurch.

- Cranston, RI, USA

The contact owns a 2016 Toyota Tacoma. While driving at low speeds and turning the steering wheel, the rpms would increase to approximately 200-300. The failure would cause the vehicle to surge. The vehicle was taken to the dealer where it was diagnosed that the vehicle was low on transmission fluid. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the dealer where it was determined that the transmission software needed to be re-flashed. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer where it was determined that the vehicle was operating properly. The manufacturer was notified of the failures. The approximate failure mileage was 1,863....updated 12/12/16 updated 12/12/16.

Noticed my Tacoma being slow to down shift to a lower gear when trying to accelerate or it would up shift to a higher gear while accelerating/merging resulting in an unexpected change in acceleration. Also if riding between 20-40 mph the vehicle rides at a very low RPM (~1100) and shimmies the vehicle like it will stall. Vehicle will also "noticeably" down shift while the foot is off the accelerator resulting in an unexpected change in deceleration. The problem seems to be getting worse and now the shifting is starting to jolt the vehicle. While driving at constant speeds the vehicle will randomly surge high in rpms then come right back down. The vehicle is presenting unsafe conditions. Took the vehicle to the dealer multiple times. 1st time they topped off the transmission fluid as it was low from the factory. 2nd time they are aware of the issue and others were having it as well and the transmission ECU was re-flashed. This still did not resolve the problem. Brought the vehicle back a 3rd time and they didn't see a problem with the vehicle. Brought it back a 4th time to be seen by a field specialist and the issue could be duplicated but there is no fix at this time because the vehicle is operating as designed. Vehicle currently has less than 2500 miles on it. Not sure why you would design a vehicle to do this.

When we are driving either on city roads or on highway, either in sports mode and automatic there is a lag in the way the engine will shift into gears. In sports mode the lag in gear shift is ridiculously long when it should shift quicker. As for automatic there is also a slow response in shifting whether going up a hill as well as going down a hill. We have 5000 miles on this truck and would have thought it would be broken in by now

Transmission has hesitation when first going in forward or reverse, once your driving the transmission is constantly shifting searching for gears until you get up to cruising speed of 50-60 mph. In city driving transmission shift to quickly and boggs down the engine and then shift right back down and gear and does this constantly at lower speeds, been doing this since I purchased the truck on August 28 2016

Truck abruptly lost complete power and stalled while driving on a rural two lane road at approximately 40 mph. Requires a tow truck to take the vehicle to the dealership. Dealership reported a failed crankshaft sensor and replaced it.

This Toyota Tacoma is always trying to shift up or down. I found where Toyota says it is always looking for a new shift point to keep the mileage up. This transmission shifts very hard with power reduction and is trying to up shift. When you are trying to come to a stop transmission trying to shift up and then it will shift hard. You will feel a driveline clunk as you stop. I took it to the dealer they said Toyota knew about the problem. They said a case was opened. I was told they drove several on their lot and they were the same. The final word was nothing wrong. This is a safety hazard. Has been doing since I got the truck.

While driving eastbound on the 210 freeway in glendora, ca at approx 35mph the vehicle came to a sudden and violent stop and veered slightly into the lane to my right. I was not braking at the time. Rear wheels had locked and vehicle had to be dragged to the shoulder as rear wheels would not turn. There were no indications of any problem at the time of the incident. Vehicle was in drive, and seemed to be operating normally. Vehicle was taken to Toyota of glendora in glendora, ca for service. I was told that the rear differential had leaked out, and it along with the rear tires had been replaced under warranty. This was a new vehicle with less than 4500 miles on it. It had not had its first oil change nor any other service. The problem was not caused by external damage, and it was explained to me by the dealership's service advisor that the part had not been properly sealed. Vehicle has no warning system or dash light to communicate a loss of differential fluid as it would with oil, tire pressure, temperature, etc.

The manual transmission consistently gets stuck in gear once the transmission is hot. This typically occurs on drives over 2-3 hours or heavy stop-go traffic. The driver cannot change gears without excessive force on the shifter, resulting in significant changes in driving dynamics while this is occurring (e.g., loss of vehicle speed, loss of engine revs, lugging transmission). Examples include downshifts from 5-6, 5-4, 4-3, and 3-2 as well as upshifts through those same gears. This presents a critical safety concern when the transmission malfunctions and the vehicle does not operate as intended. It places the driver in dangerous and potentially life threatening situations, whereby the driver is taking attention away from driving in order to apply significant pressure on the shift lever in order to get the transmission unstuck. Moreover, while maneuvering the vehicle through traffic or intersections, the driver and others on the road become vulnerable to major accidents caused by a malfunctioning Toyota transmission and the inability of the driver to safely operate the vehicle. I have contacted Toyota on several occasions. Toyota relied on an independent third party dealer to perform an inadequate inspection of a malfunctioning transmission and then proceeded to deny all responsibility; even going as far as to make the assertion that "the customer can drive the vehicle as necessary". Toyota has done absolutely nothing to review or inspect the malfunctioning transmission only to conclude it is safe to drive!

It's important to note that I own two identical 2016 Tacoma trd off road automatic and both have less than 10,000 miles. One is fine and the other has serious power train (engine/transmission) problems resulting in extremely slow acceleration and overall sluggish performance, transmission constantly shifting to compensate for lack of power, transmission slow to engage gears causing dangerous hesitation and surge, occasionally slamming into gear causing sudden jerk and lunge, cruise control in unusable due to constant gear hunting even on flat highway, vehicle is very unsafe in stop and go traffic due to hesitation and surging, and merging into traffic and busy high speed highway travel is a nightmare. The following business day after taking delivery I brought to dealer with the above complaints and was told that the computer needed to lean my driving style and it would take up to 5,000 miles. At one point dealership service tech, service adviser, and service manager acknowledged the problems and I was told that Toyota was already aware and working on a flash upgrade that they hoped would fix. I was told that I had no choice but to drive the vehicle and wait for the flash. Dealership personnel now deny any problems. I filed a claim with Toyota and dealer now refuses to try and fix the problems. This model is being shipped with very low transmission fluid according to the service tech which is certain to diminish the life of the transmission. He also said that something is wrong with the torque converter. I have filed a claim for repurchase but dealership is uncooperative and Toyota reports that after reviewing my claim that they were unable to verify any of my concerns. There are many owners reporting to be experiencing the same problems and to date Toyota has done nothing to resolve that I am aware of.

Manual transmission is hard to shift out of 4th, 5th, and 6th gear after extended highway driving. Issue seems to more present when driving up an incline after driving in stop an go traffic.

- Livermore, CA, USA

Hi to whom this may concern, I have trouble shifting my vehicle once I drive it after 4-5 hours, this is an intermittent problem that the dealer can't replicate because it doesn't happen too often. I have called corporate Toyota and they claim that no one else has called in with the issue even though there are many others that have the same issue. I have opened up a case with them with reference #: 1607081673 note: This is on a manual transmission link to a tacomaworld thread with others having the issue: Https://www.tacomaworld.com/threads/manual-transmission-getting-stuck-in-gear.415438/

Transmission seems not to engage very quickly. Very sluggish. Mostly in the morning when put in reverse it does not seem to engage. There's also a clicking noise up by the engine passenger side. Dealer says it's normal. Never heard anything like that on any vehicle I've owned

- Jacksonville, FL, USA

Vehicle is sporadic when shifting. Earlier today at a left turn at the vehicle would not shift gears giving me the feeling that the vehicle would only go at 10-15mph on incoming traffic. This was at a green light with yield if possible. If it weren't for other driver coming and being able to use breaks the vehicle would have been in an accident. I attempted to step on the accelerator but it seemed as it would not shift. Please investigate further as I've noticed the issue before but when driving straight it is not a problem. Thank you.

Clutch system developed loud sound and vibration a few months after getting brand new from Toyota. Doesn't matter if clutch was pressed for first time to turn on to shifting gears. My previous 2013 had same issue and some clutch parts were replaced by Toyota to fix the issue.

Vehicle gets stuck in gear when driving on highway for extended amounts of periods on the highway 90km +, only when transmission gets to operating temp. It also gets stuck in lower gears 1-3 when decelerating and the truck is at lower revs. Extremely dangerous when trying to downshift for a hill or corner, your foot is off the accelerator petal and truck gets stuck in gear. Toyota has taken a month and still has not come up with the decision to replace, they do not care if it's dangerous to drive. I need a truck though....

Audio system resets on its own and displays "check charging station". I had dealer look into it and they said that usb cables were defective. I thought they were looking into all possibilities and purchased new usb cables. Not the case, it still happens from time to time and does not work properly. As written by many other Tacoma owners, the shifting delay from reverse to drive and vice versa. I have 7000 miles on the truck and Toyota said there was a break in period for the transmission. They told me I had the most up to date software for the transmission. I should've never traded in my 6spd.
