BUT MOST OF ALL THE BRAKES SCARES ME I NEVER KNOW WHEN IT WILL WORK OR WHEN IT WON'T ,SO I TRY NOT TO TRAVEL WITH MY CHILDREN OR WHEN IT IS RAINING .MY VEHICHILE WAS LISTED AS RELIABLE AND LOW GAS MILAGE I HAVE TO PUT$10.00 IN EVERY DAY AND NOT TRAVEL UNESSACARILY. I HAD NOT HAD THIS TRUCK LONG AND IT IS A LIABILITY HEALTH WISE AND FINACIALLY. IF SOME ONE CAN HELP OR HAVE INFORMATION THAT MAY BE USEFULL ,I AM INTERESTEDWHAT CAN I DO OR SHOULD DO.*AK

WHEN ATTEMPTING TO BRAKE BRAKE PEDAL WAS EXTREMELY HARD. LOST ALL ABILITY TO STOP THE VEHICLE WHEN PRESSING ON THE BRAKE PEDAL. THIS RESULTED IN A 1-CAR ACCIDENT. THERE ARE SERIOUS PROBLEMS WITH THE ABS BRAKE SYSTEM ON THIS VEHICLE. THIS WAS PART OF THE 1999 RECALL AND WAS IN FOR SERVICE. LAST YEAR THE LOSS OF BRAKING WAS EXPEREINCED AND A SENSOR ON THE ABS SYSTEM WAS REPLACED. THIS RECENT ACCIDENT OCCURRED AFTER 6500 MILES ON THE REPLACED SENSOR.*AK

AFTER THE VEHICLE WARMED UP THE OIL PRESSURE GAUGE WOULD READ ALMOST 0. STARTED READING OK UNTIL IT WARMED UP. TOOK IT TO THE DEALER AND THE ONLY THING THEY COULD FIGURE OUT WAS THAT THE OIL PUMP HAD GONE BAD. THEIR PRICE QUOTE WAS UNREAL (+ OR - $3,200). WE TOOK IT TO A LOCAL MECHANIC AND THEY ESTIMATED $1,200.00. HAD TO DROP THE TRANSMISSION THEY SAID TO GET TO THE OIL PUMP. THIS YEAR (2003) THE GAUGE IS ACTING UP AGAIN. IT STARTS OUT FINE AND AFTER IT WARMS UP, IT DROPS TO ABOUT 10 ON THE PRESSURE GAUGE. WHEN YOU ACCELERATE THE PRESSURE GOES UP TO MAYBE 20 OR SO ON THE GAUGE. I AM NOT EXACTLY SURE ON THE EXACT PURCHASE AND INCIDENT DATE. BUT THEY ARE APPROXIMATE. I HAVE FOUND NUMEROUS ARTICLES ON THE INTERNET RELATING TO GMC AND THE FAULTY OIL PRESSURE GAUGE/READINGS. I COULD NOT FIND ANY SPECIFIC RESEARCH THAT POINTED TO THE EXACT PROBLEM. WHETHER IT WAS THE GAUGE, THE ENGINE OR ETC. I TALKED WITH FRIENDS AND RELATIVES THAT OWN THE JIMMY OR BLAZER AND THEIRS WAS ACTING THE SAME WAY. *NLM
