Waiting for renewal of PR card - can I travel

[nycto]

Hi - I am an Indian passport holder and my PR card expired last year. I applied for renewal for it in April after completing over 730 days in Canada. I am currently working in Toronto and will be gainfully employed for the future. I am still waiting on the renewal (I was asked to provide a list of dates of travels in and out of the country but have heard nothing else so far)

I am planning to make a trip to the US. I am not visa exempt for Canada but am planning to re-enter by car. Can I enter with just my landing papers?
Can the visa officer revoke my PR status or cause issues to the current renewal processing?

Thanks for your help!
