T-Boz Targeted By Honda -- We're Taking Your Odyssey

T-Boz might be forced to travel in the passenger side of her best friend's ride ... 'cause Honda is gunning to repossess the singer's car.

TMZ has learned ... Tionne Watkins is being sued by Honda for failing to make payments on her 2005 Honda Odyssey.

In the lawsuit, filed in Georgia, Honda asks the judge for the green light to take the car back. It's unclear how much T-Boz owes in back payments.

It's just the latest in a string of financial woes for the 42-year-old singer -- she filed for bankruptcy back in 2011 ... but failed to complete the required paperwork ... and lost the protection bankruptcy provides.

In other words, there's NOTHING stopping T-Boz's creditors from coming after all of her possessions.

We reached out to T-Boz for comment -- so far, no response.
