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.

Incident

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 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.

- 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].

I have experienced short periods with my Tacoma accelerating when my foot wasn't on the gas pedal. The floor mat was pinned down correctly and not in the way. I was turning left and my truck started to speed up like the gas was being pressed. I had to hit the brakes as a red light was coming and vehicles were stopped at the Red light. I have also had another issue with the truck not responding when the pedal was pressed all the way down and the truck wouldn't speed up at all for a few seconds.

The truck will accelerate on its own during highway speeds of 60+ MPH and residential 25+ MPH. Also accelerates when coming up to a stop sign causing me to almost hit a child in a crosswalk. There was no cruise control engaged during the incidents. I took it into the Autonation toyota dealership twice and they said they could not reproduce and or duplicate the problem. It is very frightening when it happens as it lasts between 4-5 seconds if you do not apply the brakes hard. There has not been any warning lights or anything that comes up on the dash board.

I buy a Toyota Tacoma 2021 on 5 of June 2021 in Toyota Walnut Creek California. And I have to sell it again on 15 november 2021 5 months later. Ok I was driving in a long trip of 9hrs. And I adjust the seat to be comfortable to drive but I notice that when I was looking to the front right side the mirror in the center to look to the back was in the way of my view, and I drive , moving my head down to look under the mirrorevery time when I look to the right front. A the end of the trip I get tired driving that way. Next time I was driving in Oakland Ca. I was in a stop waiting to turn to the left side in a road, and the cars in the other side in front of me the put me the high beams,and I was thinking they give me the pass, and I look around to drive,and right away 3 persons was in front of me, and thanks to GOD I don’t drive over and kill them. And I get very mad frustrated , I was ready to break the mirror with my right hand, but I control my self and don’t do it. That was when I notice the mirror and the black spot is in the mirrow is a very bad location, that take lot of view to the front right side, they need to relocated all the sensors are in that area. I sold the truck no because I can’t drive it eny more.I call Toyota I they. Don’t pat attention.

I PURCHASED A NEW 2021 TOYOTA TACOMA IN DECEMBER 2021 WITH A PRE COLLISION SAFETY SYSTEM. LESS THAN 2 MONTHS LATER, MY DAUGHTER WAS IN A FRONT END COLLISION ACCIDENT (DAUGHTER AT FAULT). THE SYSTEM DID NOT DO WHAT IT WAS SUPPOSE TO, WHICH WAS WARN HER AND HELP HER APPLY THE BRAKE. AT THE REPAIR CENTER, I ASKED THEM TO CHECK THE PRE COLLISION SAFETY SYSTEM. THEY TOOK THE VEHICLE TO BERT OGDEN TOYOTA TO HAVE THE VEHICLE CHECKED OUT. THEY TOLD ME THE SYSTEM WAS PROBABLY OFF OR NOT SET SENSITIVE ENOUGH AT THE TIME OF THE ACCIDENT. NOW THAT I HAVE THE VEHICLE BACK, I HAVE SET THE PRE COLLISION SYSTEM TO THE MOST SENSITIVE SETTING AND IT APPEARS IT IS NOT WORKING. THE SYSTEM HAS FAILED TO WARN ME (ON THE MOST SENSITIVE SETTING) AS I ACCELERATED TOWARD A BRAKING CAR. I TOOK THE VEHICLE IN TO TOYOTA OF PHARR AND SPOKE TO A SALESMAN, WHO TOLD ME ALL OF MY SETTINGS WERE CORRECT AND IT SHOULD BE WORKING. THOUGH THIS FAILURE WAS MINOR IN MY DAUGHTER'S CASE WITH NO ONE HURT (THOUGH IT DID COST $7,000 TO REPAIR), THIS SYSTEM IS NOT WORKING AS ADVERTISED AND IT IS A MATTER OF TIME BEFORE SOMEONE GETS HURT.
