TSBs (Technical Service Bulletins)
Please note: The TSB information displayed below are summaries. We do not have access to the full versions. To get full information about a particular TSB, write down the TSB title & date, & either contact your local dealer or click on the links below.
The TSB numbers are the NHTSA numbers, which are different from the manufacturer-assigned TSB numbers — the NHTSA doesn't keep track of those. It's a very screwed up situation that's almost completely unhelpful to you as the consumer. Use the issue date or the title when asking your dealer for more information about a TSB.
