Cruise Control problems of the 2018 Toyota Tacoma

My 2018 Tacoma had a check engine light come on, then the trac light came on. Cruise control quit working and engine runs rough. When driving, vehicle begins to lose acceleration and check engine light begins flashing. When idling, engine runs with with a miss, and when driving, at lower speeds the vehicle shudders as if its losing power.

Tl- the contact owns a 2018 Toyota Tacoma. The contact stated that while driving with the cruise control activated at 72 mph the vehicle speed erroniously increased to speeds of more then 90 mph. Also the collision avoidance system malfunctioned and did not slow or stop the vehicle when approaching a second vehicle. In addition while the cruise control was activated the vehicle would suddenly slow down after the cruise control erroneously deactivated. The cause of the failures were not identified. The local dealer chatham parkway Toyota, (7 park of commerce way savanna GA) was contacted regarding the failures. The manufacturer was not yet notified. The contact indicated that the vehicle was previously serviced to repair a wave radar sensor. No further information was available. The failure mileage was 12,957. Jft.

With laser cruise control on, vehicle will suddenly slam on the brakes and release with no other vehicles in front of it. This has happened 8 or 9 times in the time I have owned the truck. I have taken it back to the dealer 4 times for this problem, only to be told that they cannot duplicate it and nothing was done to repair the problem. The next day I received a recall notice to bring the truck to Toyota to repair a front sensor for this problem. I brought the truck in to the dealer and they said that water was getting into the front grill sensor and they glued a piece of rubber/foam over the sensor. A few days later the same thing happened again. My wife and I are afraid to even drive the truck and Toyota has said everything is ok. The second problem is with laser cruise on and set at 75 miles an hour traveling up a grade, the vehicle will downshift into third gear running the tach to 300 rpm's over the redline. Toyota says that this is fine and the truck has a governer to keep the truck from over revving 300 rpm's above redline at 5800 rpm. I explained that in the owners manual it says to never run the engine to redline. Again Toyota says this is normal and that they will not fix the problem. Redline is 5500 rpm.

Tl the contact owns a 2018 Toyota Tacoma. While driving approximately 65 mph with the cruise control activated, the vehicle suddenly accelerated to over 100 mph. The vehicle was taken to suburban Toyota (35200 gran river Ave, farmington hills, mi) where it was diagnosed that the failure was due to a faulty sensor. The vehicle was not repaired. The contact indicated that the failure occurred on multiple occasions. The manufacturer was not notified of the failure. The failure mileage was 19,500.

Transmission locks out in 4th gear, mid speed surge, surge at idle when turning the wheels. Cruise control doesn't function it will increase rpm's on a flat road.
