None of the buttons on my Steering wheel work, along with the cruise control

Clock spring sounds like it failed.

Buy a good quality one.

 

Agree with Ray. Clockspring is the number one suspect. It's the wire that is coiled up like a clockspring in a mechanical watch. This wire is inside the steering wheel and is a fairly simple item to replace DIY. Best of luck!

 

I have read diverging reports about the cheap clocksprings. Some say stay away from them and others, with lots of professional repair experience say the cheap ones and expensive ones are the same and the difference is in certifications a brand name has to get in order to connect to an airbag. I would make sure to buzz the cable with a continuity probe on every conductor before installing and if it's all good would not worry about it too much. Also, follow installation instructions properly as improper installation can lead to early failure.

Good luck!

 

My $ is on OP will be replacing clockspring again. Others before him have gone cheap and regretted it.

I would have hoped OP's life is worth more than $15.

Toyota trying to locate “thousands” of counterfeit airbag parts that could prove deadly in a crash

"... internal testing in Japan found there were four ways they could fail to deploy an airbag in a crash."

“high likelihood of insufficient conductivity to support airbag deployment electrical current” and “significant risk of airbag non deployment in an accident”.

counterfeit part does not have gold plated connectors, the crimping of the cable is not strong enough and it does not use copper wire as per the genuine article. The plastic locking tabs are also “poorly formed” or misaligned.​

1) You get what you pay for.
2) Certification = testing = reliability = lives saved (assuming its not a defective Takata Air Bag). The imitation junk from Panda Land (China) lack quality control, testing, and are always made with the cheapest materials (to maximize their profits at your expense).


This reminds me of people who buy Panda Land auto fuses b/c its cheap. They later pay for it dearly with damaged equipment and wire harness. Watch this auto fuse testing from Weber State's Automotive Department.

 

A month ago all the buttons on my steering wheel failed within about 100 miles. A year ago I purchased an $8 clockspring off Ebay. Yeah, it was cheap.. but I like cheap.

So, I got a year out of it, almost to the day. When I took the clockspring apart I found no failure in the ribbon cable. I'm still looking for the failure points.

This time, I cheaped out again.. and purchased not one, but TWO $8 clocksprings. One is now sitting in the Prius' tray above the spare tire. Hey, you never know, just in case I need to change it on the fly, it's there. It's one of the easiest jobs you can do on a Prius. I hope to get at least 13 months out of the new one.

 

It's fixed by taking the wheel off again and putting it back on in the proper position. (You can save time by making match marks on the wheel and shaft before you remove it in the first place.)
