Rear differential noise effecting all 2016 and 2017 Tacoma trucks. Toyota has already replaced differential, this made no improvement ,the noise is the same. Toyota fst sad they are aware of the issue and working on a correction. I just hope this is fixed before the rear end locks up on someone Tacoma and causes an accident.

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.

Failure Date: 10/06/2016

The rust on the rear end assembly is so severe that the brakes are compromised, and the back up emergency brake system has failed. The rust on the differential housing is so severe that the fluid has leaked out and the gears are at risk for catastrophic failure. The spring mounts to the axles are also rusting severely, creating a risk of lost control should either side break away. It takes great effort when braking, and the vehicle pulls severely due to rust causing the loss of integrity of the braking system. The brakes, once applied, do not release evenly, creating uneven brake wear, shuddering and shaking, resulting in poor control, excessive and uneven tire wear, I. E. , tires locked and dragging, scalloping. On wet, and I fear, icey, surfaces, the truck has slid sideways due to one or more wheels not releasing.

Failure Date: 09/30/2016

My new Tacoma has a whine/howl coming from the rear differential. Per my dealer, they have started a tas case with Toyota corp and were advised that the condition described is known, and under investigation. Tas says there are no recommended repairs at this time. The problem is occurring between 30-65 mph when decelerating and feathering the throttle, but is now becoming more pronounce with time and more mileage. I�m concerned that the issue could potentially become a safety issue. This issue is occurring with 2016-17 Tacoma's. Many differentials have been replaced by dealers; even the replacement differentials are experiencing the same issue.

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.

First incident occured while vehicle was stuck in light snow and ice condition. 4-wheel drive system did not appear to be operating properly. Engaged new "crawl-control" system per owner's manual instructions. During use of crawl-control the motor rpm's exceeded 5,500; immediately pressed engine-stop button and applied brakes. Incident resulted in catastrophic damage of front drive-line. Damage included front drive-shaft failure; dealer indicated "drive-line" replaced. Significant damage to components adjacent to front drive-shaft. Vehicle repaired under warranty. Two days after service random brake lock-up occurs while driving; vehicle skids out of control. No malfunction indicators showing. Abs also does not activate during panic stop brake application. Brake lockup experienced in winter conditions at high elevation nearly causing potentially fatal accident (1,000ft drop from road to canyon bottom, no guard-rails). While driving at 30mph the rear end of the truck begins to slide sideways. Upon coming to a stop it is discovered that the vehicle will not drive forward. Engaged 4-wheel drive and vehicle struggled to move. Engaged differential lock and drove backwards for 80ft. Wheels appear to become un-locked.

The differential needed replacement at <10,000 due to a loud howling noise when cruising at 55 mph. The noise was noted when I first picked up the vehicle from the dealership, but the volume got much louder over time. Even my 4 year old child asked, "what's that sound?" the service records noted metal "silver shavings" were found in the differential. Even after replacing the differential, there has been no change in the howling sound at 55 mph. I'm concerned the differential is defective. Many other Tacoma owners have reported the exact same symptom. . Read more...

Oil changed at Toyota dealer, mechanic discovered rear differential leak. Took the vehicle to private mechanic and discovered the rear differential leak was caused by rust to the body.

Failure Date: 02/13/2013

Loud noise coming from the rear end. It appears the differential case rotted out leaving the rear end with no gear fluid. When they replaced the frame (as it rotted out to). . . They shoud have replaced the differential housing. Lucky this happen around town and not on the highway. I can imagine what would have happened if the differential blew apart at high speed (with flying metal and no control of acceleration if needed to avoid or cause an accident). I called Toyota car care and they said they would go in half on the repair and get back to me in a few days with the details. They didn't. . . I called them a few days later and they said they couldn't help me. Looked to be a +/- $2,000 repair.

Failure Date: 12/17/2012

My 2004 Toyota Tacoma was recalled in 2012. The recall letter stated that in certain states where road salt is used to manage winter driving conditions, the potential existed for premature rust/corrosion of the frame. I brought the truck in to the dealership where it was then determined that the frame should be replaced. Six months later I noticed that the rear differential housing was leaking. Why didn't the recall cover these components, which are located in the same general area and subject to the same corrosive conditions as the frame, leaf springs, control arms, etc. , all of which were replaced? if the fluid drains from the housing as a result of rust/corrosion, the potential exists for the drivetrain to lock up, especially at higher speeds, resulting in an obviously dangerous situation. No real options exist to address the issue aside from replacing the differential housing, a repair that costs several thousand dollars. My complaint is that Toyota chose not to cover the replacement of all parts necessary in order to insure the safe operation of the vehicle in light of the premature rust/corrosion issue, nor did they raise the issue in any way. I cannot imagine how Toyota could be unaware of this condition.

Rust out of the differential cover. All of the oil in the differential leaked out. No parts are available from Toyota. The complete differential must be replaced at a cost of over $ 1,000. 00. This is a major problem as per many Toyota forums on the net. Toyota will not stand by this repair and will not admit to any problem about rust.

Rear differential whines/roars at speeds 50-70 which indicates there is a failed component within. Toyota issued technical service bulletin t-sb-0076-08 for problem. Dealer, john royberts Toyota of manchester, TN, attempted to repair but could not. Now, says all Tacomas have whine/howl, a normal condition. If this is true, then ever Tacoma has a potential problem of differential lockup while driving which could cause deadly accidents.

Failure Date: 07/20/2010

I have a 2009 Toyota Tacoma and when the vehicle is stopped for example at a red light the vehicle rpm will increase and the vehicle will then lurch forward. Fortunately my foot in on the brake. The vehicle also has a whining noise from the rear of the vehicle that has been identified by Toyota regional reps as a whining noise from the differential at 50 to 70 mph. Taken back 3 times to dealer they say its normal but I know it is not. These may be 2 sperate issues but it is clear that Toyota makes it difficult for is customers to get warranty reapirs and in acknowledging a problem. Toyota should be ashamed for its lack of customer service in fixing its vehicles until people get injured.
