The high mount rear stop lamp leaks water into the cab. The water channels in through a cheap gasket, down the inside of the frame, destroying the cushions and plastic through moisture and mildew. Toyota Corporation and Precision Toyota of Tucson (service) AZ, both say the problem is only covered by the regular 36,000 mileage, 3 year warranty. They want to charge me $575 to replace the light. However, the known issue doesn't occur because of miles driven or even age of the vehicle. I live in the desert and it has not rained significantly since I bought the truck new in 2017, according to the National Weather Service. This year, with record rains, water is freely seeping in to the cab. Toyota should recall Tacomas with this issue and replace the cheap gasket it used to manufacture these trucks.
Clock spring has failed. I've lost all steering wheel button controls as well as cruise control. Air bag light has now come on. I am afraid that if I get into a wreck, the airbag will not deploy. This seems to be a common issue with this select year for this Tacoma.
Left turn signal quit working while driving on a city street making a left turn. Toyota took 4.5 hours to diagnose the problem. Said it was in the instrument cluster affecting the turn signal and odometer. Said it would take a week to get part and they needed to know how many miles I would drive in that week because the odometer had to be set to existing miles plus the miles I drive during the week. One week later was told the part was on back order and it would be 30 to 60 days for the part. I googled the problem and found many complaints of "left turn signal going out" on Toyota tacomas dating as far back as 2012. Obviously Toyota knows of the problem. Have they fixed the problem on the replacement part or is it pron to go out again. …
Purchased truck July 24, 2017 from mark miller Toyota in salt lake city, utah. In the first 6 months I lost brakes 3 times. Went to dealer each time. They couldn't duplicate so no repairs made. After the 3 times a recall came out, 18V888. Exact symptoms. Then a forth time happened and they said the recall doesn't effect my VIN so they still have to duplicate. Today, February 27, 2019 truck wouldn't stop and I ran thru a stop sign, and it was cont on my dash cam. With this problem my seats are loose and sometimes don't lock. When ever in 4 wheel drive the seat belts lock up and wont unlock lock. I've had nothing but issues with this truck and nothing will ever get fixed and I'm scared to drive my vehicle especially when my dealer won't repair anything. Also believe it has something to do with the vehicles off-road option, crawl control, which uses ABS.
The speedometer would get stuck and not display an increase or decrease in speed while driving. Or it would display an increase in speed up to 60 MPH and then treat 60 as 0. Ex. I was going 45 but it read that I was going 95. Or sometimes, it would just increase all the way to 120 MPH and then stop. Turning the vehicle off and then back on did not make a difference. The gauge would still read where it was when the car was turned off. I was never sure of the speed I was going and brought the vehicle into the dealer within a month of the occurrence. The truck was only 10 months old. The vehicle has been at the dealership for 2 months. They are waiting on Toyota to create & ship a new speedometer because Toyota identified that the speedometers in some of their make/models were faulty.
