Two problems related to engine grinding noise have been reported for the 2016 Toyota Tacoma. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 Toyota Tacoma based on all problems reported for the 2016 Tacoma.
All of the problems listed below have been reported to my local Toyota dealership, gullo Toyota, conroe, texas. 1) engine misfires (5 attempts at repair. Still misfires. ). 2) vehicle stalls due to transmission searching for the correct gear (developed after the last attempt to repair misfire in September 2016). 2) engine has developed a rattle after 20,000 + miles and sometimes sounds like a rod is knocking. Sounds like engine is not being lubricated properly. This may lead to early failure of the smog control system and excessive oil consumption (Toyota claims this is normal for this truck). 3) bump sound comes from beneath truck when stopping and may be loose or broken motor or transmission mount (Toyota stated that the truck is operating as designed). 4) grinding sound comes from rear end when rear wheels slip and automatic limited slip is selected (Toyota has stated that the truck is operating as designed). 5) engine revs unexpectedly when backing out of or driving into garage (Toyota has stated that the truck is operating as designed). 6) loud bang comes from beneath truck when coming to a quick stop. Sounds like the guts of the transmission shift forward (dealership has not arranged to provide a loaner truck so that this problem and all the persistent problems listed above can be repaired. Toyota insist that I bring my truck to the dealership and drive my truck around and demonstrate the existence of these problems to the Toyota's field service tech. Dealership is aware that this truck has been recalled for rear differential problems and engine misfire and stalling. I need the dealership to accept responsibility for this defective truck and take it into their service department and keep it until it is repaired. I need a loaner truck while the repairs are made. I have put much needed work on-hold for a year due to this truck. ).
Chirping noise comes and goes. Very loud. Also a constant clicking. Anything that makes noise like that will fail soon. Also had a grinding noise while in four wheel drive on beach and truck started to lose power. Grinding went away but happens often.
