Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
1
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

I PARKED THE CAR IN MY DRIVEWAY AND THE PASSENGER SIDE MIRROR STARTED CLICKING. THE MIRROR WAS ATTEMPTING TO ROTATE TO THE EXTREME CAR SIDE OF THE MIRROR. USING THE REMOTE MIRROR CONTROL HAD NO EFFECT.THE CAR WAS TURNED OFF AND THE MIRROR MOTOR CONTINUED TO TRY TO MOVE THE MIRROR PAST THE LIMIT. AFTER SEVERAL MINUTES, THE CLICKING STOPPED AND THERE WAS AN ODOR OF PLASTIC BURNING. AFTER THE CLICKING STOPPED, NEITHER MIRROR MOVED. THE LOCAL MECHANIC SAID THE WIRING TO THE MOTOR HAD BURNED AND SHORTED THE MECHANISM. I WAS LUCKY THAT THERE WAS NO DAMAGE TO THE INTERIOR OF THE DOOR. HAS THIS MALFUNCTION BEEN A PROBLEM WITH THE TRAILBLAZERS? *TR

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

PIP5601C

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

PIT3271P

This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

General Communication

ELECTRICAL SYSTEM

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

24-NA-141

POWER TRAIN

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

16-NA-383

ENGINE; FUEL/PROPULSION SYSTEM

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

18-NA-099

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
