Defect investigations
Parking brake failure
In a letter dated april 20, 2005, gm notified the federal safety agency that it had decided that defects that relate to motor vehicle safety exist in certain model year (my) 1999-2002 c/k 1500 series (pbr parking brake system) and my 2001-2005 c/k 2500 and 3500 series (trw parking brake system) pickups with manual transmissions.according to gm, some of these vehicles may have conditions that cause the friction linings to wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.gm's action covers an estimated total of 142,585 vehicles.dealers will install a low-force spring clip retainer for vehicles equipped with the pbr parking brake system and install a redesigned parking brake cable assembly on vehicles equipped with the trw parking brake system. A total of 58 non-duplicative complaints were received by odi and gm concerning the approximately 59,000 my 1999-2002 c/k 1500 series pickup trucks with the pbr parking brake system.these included 22 alleged rollaway incidents, resulting in a rate of 38.5 rollaway incidents per 100,000 vehicles.odi is aware of 24 complaints regarding the my 2001-2005 c/k 2500 and 3500 series manual transmission trucks recalled by gm, including 5 alleging rollaway incidents.though the conditions described in gm's letter are also present in the c/k trucks with automatic transmissions, the rollaway rate in those vehicles was similar to those observed in peer vehicles studied by odi in this investigation.this engineering analysis is closed.

What 2003 GMC GMC owners say
Most recent owner complaints, unedited.
Driver seat can't be preset for driver 1 or 2. Often when the vehicle is started, the seat goes all the way up under the steering wheel. At other times the seat remains so far back that nobody can reach the gas/brake pedal. Each time anyone drives the vehicle the seat must be reset or readjusted. Gmc has been taken to a repair facility many times before the warranty was up, but the repair center said they had no idea or remedy for this problem.
I read an article today in the detroit free press which has prompted me to write you regarding hidden lamps. My complaint is general, in that the amount of "dazzle" from the scattered light is greatly objectionable, and must be controlled. "head-on" viewing os acceptable, but slight off-angle is extremely distracting and painful from these lamps. I work for a major auto company, and have some experience in lighting technology. I would prefer if the federal safety agency migrate to european requirements (cut-off lines) and enforce some type of anti-dazzle requirements for these lamps. Although allowing a "wash" in front of the vehicle on the road, the side scatter I believe is more dangerous, possible causing or relating to oncoming driver irritation, road rage, or possible accidents.
