Following up: After speaking with our Chevy dealer, they agreed to replace the intermediate steering shaft (again) to try and fix the rattle. It didn't work (again). They then replaced the steering column. The rattle was fixed. The mechanic told me that rattle (described above) can come from either ...

Just to tie up this thread: The evap leak was a hole in one of the vacuum hoses. The car sat with the previous owner, and it appears a chipmunk or other rodent had some fun. I wasn't able to find the leak, but the dealer did and covered the repair, admitting they should have noticed it before sellin...

I did replace the gas cap with an identical ACDelco one. No change. Reading on other threads here, an evap leak can shut down the Sensatrack and VSC. Even a loose gas cap can apparently cause the same issue. It seems odd to me that the issue would only reappear 300+ miles after each reset. It seems ...

The Check Engine Light, VSC, and traction control lights all came back on a couple days ago. I got an OBDII code reader. It was $25 and both our cars are throwing codes right now. I'm getting P0441 and P0455. P0441: Evaporative Emission Control System Incorrect Purge Flow P0455: Evaporative Emission...

New gas cap arrived. It's identical to the first--stops at one very weak click. This seems like a really flimsy design to me. A friend of mine who is an engineer with Toyota also pointed out this was the same cap design used on his 2010 Toyota Prius, which he ended up replacing with a generic non-ra...

On the several GM forums they discuss the same type of rattle, with the same symptom of it returning several thousand miles after the column is replaced. On a truck forum, one user had some success by strapping a zip-tie around the point where the steering column connects to the intermediate steerin...

Just a follow up. The Toyota and GM part numbers I listed point to the same part in different boxes. That was confirmed with a local mechanic and a warehouse operator near Detroit. Unfortunately, replacing the intermediate steering shaft didn't solve the noise, which was identical in symptoms to wha...

The GM part number for the non-AWD intermediate steering shaft is 19183820 The AWD part is 19183821.

A mechanic I spoke to at a local Chevy dealer thought that GM had also updated the part, but he wasn't sure.

Thanks for your replies. I am working with the Chevy dealer we got this car from to work out the intermediate steering shaft issue. Others online have had success getting GM to cover all or most of the repair cost, but a GM part is used in the replacement. I compiled what info from this thread and e...

Thanks for the replies. That is exactly the design of the gas cap on mine. My wife and father-in-law have similar GM/ACDelco gas caps with the same "Turn until 1 click" on the cap. Their caps both continue to tighten through multiple clicks. I have to twist fairly hard on mine to get a sin...

The code was P0440 on the second and third visits. I didn't ask on the first. It sounds like a gas cap that only clicks once and won't continue to tighten is suspect. I'll try swapping it out. On all other GM autos I can remember, the gas cap clicks repeatedly until it's too tight to turn. On our Vi...

I just purchased a used 2010 Pontiac Vibe with 19000 miles a week ago. I've noticed the gas cap won't tighten beyond a single click--a click that feels different than other ratcheting gas caps I've had. Is this normal? I ask because the check engine light has come on three times since we've gotten i...

Thanks to everyone that's posted info here. Can anyone confirm that the Toyota Matrix intermediate steering shaft is compatible in 09-10 Vibes? We got out 2010 Vibe last week and at exactly 20000 miles ours started the tell-tale knocking/clunking so may others have described. I'd have it replaced in...
