“The ecu itself is not working, which they are supposed to never stop working. Well ours stopped working and the licensed mechanic will not work on it if it is recalled. We are literally waiting on Toyota to fix our car. They have not done so. The hole ecu not just part of it.”
NHTSA complaint #11233048, filed 2019-07, 208,000 miles“I received a letter from Toyota in march 2014 notifying me of a safety recall involving the electronic control module for the supplemental restraint system. I took the vehicle to the local dealer to have the remedy installed, which they did. In approximately february of 2015 (six months ago) I received a second letter informing me that the original remedy is not sufficient, that the srs ecu must also be replaced and I would receive notification when the parts were available to correct the problem. …”
NHTSA complaint #10759526, filed 2015-08, 118,000 miles“I was alone in the car and had driven into my driveway (after opening the garage door) to enter the garage. The car suddenly took off and before I knew, I had crashed into the side of the garage and went through it. The car smashed into gardening tools, snow shovels, lawn mower, leaf blower, trash cans, and flowering pots. It came to a stop partly by the coat closet wall that protrudes into the garage and partly by all the stuff that got caught under the car. The garage door railing was damaged and the door was hanging a few inches above my car. I heard things falling above me. …”

NHTSA complaint #11163851, filed 2018-12, 110,000 miles“There was a recall initiated 27 march 2014 for the supplemental restraint system (srs) electronic control module (ECM). Toyota mailed letters on 05 may 2014 advising owners of the recall. As of today (16 sep 2014), Toyota has failed to provide the parts and/or fix the srs ECM. As of today, Toyota does not have an estimated date that the parts will be available to remedy this recall #14v147. Since this is a safety issue and the airbag could deploy unexpectedly at any time, please direct Toyota to provide the parts and fix this safety issue as soon as possible. …”
