This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Toyota's pre collision sensor is unreliable and intermittently produces an error "pcs sensor unavailable -- clean sensor". the safety portion of this complaint comes when dynamic cruise control is set. When the sensor no longer detects a vehicle in front of you, and there is clearly there, the vehicle will accelerate at a high rate of speed before the error shows on the dash cluster if the cruise control is set above the traffic flow. I expect and realize that this situation could occur, and I avoid using the system. However, if somebody not familiar with this fault is using the pcs sensor and does not realize this problem, they will end up rear ending another vehicle, possibly at a high rate of speed before the system shuts itself off and lets off the throttle. I know I am not the only person dealing with this issue. Several others on different forums have described similar situations where accidents have been narrowly avoided because of this fault. The local Toyota dealership has been helpful in resolving this issue and have pulled codes for a forward camera communication issue. A new camera has been ordered and will be installed next week.
The pre collision warning light illuminates a various times. The cruise control will not work when illuminated. The sensor has been kept clean. It does not give a failure code at the dealer. It was reprogramed. The pre collision braking was a major feature in my buying process and it does not work correctly.
Received a pre-collision malfunction and trailer brake error multiple times. Was informed the fault occurred due to cold weather. Was informed that recall software update would resolve issue but has occurred twice since with the latest occurring 1/12/2018. Also, have been experiencing a rattling/vibration noise coming from the passenger side dash since purchasing the vehicle in October; Toyota hq involved. Latest diagnosis is a faulty ECU; awaiting repair and validation.
