The 1996 Bravada is essentially a dressed-up S-10 Blazer/Jimmy with SmartTrak AWD and the Vortec 4.3L V6. The engine itself is fairly robust, but intake manifold gaskets and transmission cooler lines are problem children, plus the 4L60-E transmission has predictable failure points.
Intake Manifold Gasket Failure (Upper Plenum)
Common · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: coolant loss with no visible external leaks, rough idle when cold, white smoke from tailpipe on startup, coolant in crankcase (milky oil) in severe cases
Fix: Replace upper and lower intake gaskets, plus spider injector o-rings while you're in there. 4-6 hours labor. Delco or Fel-Pro updated composite gaskets required—original plastic ones fail.
Estimated cost: $600-1,200
4L60-E Transmission Failure
Common · high severity
Typical onset: 120,000-180,000 mi
Symptoms: slipping on 2-3 upshift, delayed engagement into reverse, no forward gears (3-4 clutch failure), burnt transmission fluid smell
Fix: Rebuild required—3-4 clutch pack burns out most commonly. 8-12 hours for R&R and rebuild. Consider TransGo shift kit and upgraded clutches during rebuild. External cooler lines also corrode and leak at crimps.
Estimated cost: $2,000-3,500
Front Upper Ball Joint Separation (NHTSA Recall)
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: clunking over bumps, loose steering feel, uneven tire wear on inside edge, catastrophic loss of steering control if joint separates
Fix: NHTSA recalls covered this twice—check if yours was done. If not, replace both upper control arms with AC Delco assemblies (ball joints are pressed in). 3-4 hours labor, alignment required.
Estimated cost: $600-900
CPI (Central Port Injection) Spider Assembly Leaks
Common · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: fuel smell in engine bay, hard starting when hot, rough idle, loss of power under load, check engine light with lean/rich codes
Fix: The poppet nozzles crack and leak raw fuel into the plenum. Must drop upper intake to access spider. Replace entire assembly with MPFI (multi-port) retrofit kit if budget allows. 4-5 hours labor.
Estimated cost: $500-1,000
SmartTrak AWD Transfer Case Encoder Motor Failure
Occasional · medium severity
Typical onset: 100,000+ mi
Symptoms: service AWD light on dash, stuck in 2WD or AWD, grinding/clicking from transfer case on turns, won't shift into desired mode
Fix: Encoder motor on transfer case fails (plastic gears strip). Motor itself is $150-300 part, 2-3 hours labor to replace. Sometimes just needs resealing and cleaning of contacts.
Estimated cost: $400-700
Fuel Pump Failure
Occasional · high severity
Typical onset: 100,000-160,000 mi
Symptoms: no start condition, stalling when fuel tank below 1/4, whining noise from rear, loss of power under acceleration
Fix: In-tank pump fails. Must drop fuel tank (18-gallon plastic). Replace pump assembly and strainer together. 3-4 hours labor. AC Delco pump recommended—cheap pumps fail quickly.
Estimated cost: $500-800
Distributor Cap/Rotor and Optispark Issues
Occasional · medium severity
Typical onset: varies—often 60,000+ mi
Symptoms: no start in wet weather, misfire under load, stalling, hard starting, check engine light with misfire codes
Fix: Cap/rotor are basic maintenance (1 hour), but if moisture intrudes repeatedly, the ignition coil or optical sensor inside distributor corrodes. Full distributor replacement runs 2-3 hours.
Estimated cost: $200-600
Owner tips
Change transmission fluid every 30,000 miles with Dexron III—these 4L60-Es hate neglect
Use Dex-Cool compatible coolant only and flush system every 3 years to prevent intake gasket degradation
Inspect transmission cooler lines at radiator and transmission—they rust through at crimps
Check ball joints every oil change after 60k miles—play in uppers is a safety hazard
Keep fuel tank above 1/4 to extend pump life and prevent pickup screen clogging
Buy only with documented transmission work and recent intake gaskets—budget $2,500-4,000 for deferred maintenance on a 100k+ mile example.

CERTAIN REPLACEMENT FUEL FILTERS, FRAM BRAND NAME P/N G3727, WITH DATE CODES X52911 THROUGH X60801 SEQUENTIALLY OR X600141 AND A MEXICO COUNTRY OR ORIGIN MARKING ON THE FUEL FILTER HOUSING MANUFACTURED FROM OCTOBER 18, 2005, THROUGH MARCH 21, 2006, SOLD FOR USE ON THE VEHICLES LISTED ABOVE AND ON CERTAIN SCHOOL BUSES. (TO SEE THE SCHOOL BUS ENGINE SIZES, CLICK ON "DOCUMENT SEARCH" AND THEN "BUS APPLICATIONS"). THE CONNECTOR ON THE FUEL FILTER WAS NOT MANUFACTURED TO HONEYWELL'S SPECIFICATION. AS A RESULT, THE O-RING MAY NOT SEAT CORRECTLY ON THE FUEL LINE.
Consequence: THIS CONDITION MAY CAUSE AN INADEQUATE SEAL AT THE CONNECTION, POTENTIALLY LEADING TO A FUEL LEAK. IN THE PRESENCE OF AN IGNITION SOURCE, A FIRE COULD OCCUR.
Remedy: HONEYWELL WILL NOTIFY OWNERS AND REPLACE THE FUEL FILTERS FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 18, 2006. OWNERS MAY CONTACT FRAM CUSTOMER SERVICE AT 1-800-890-2075 (OPTION 1).
VISIBILITY:WINDSHIELD WIPER/WASHER · 03V159000
2003-04-28 · EA02006
ON CERTAIN MINIVANS, PICKUP TRUCKS, AND SPORT UTILITY VEHICLES WITH CERTAIN MODEL-ENGINE COMBINATIONS, THE WINDSHIELD WIPER MOTOR MAY FAIL DUE TO CRACKED SOLDER JOINTS ON THE CONTROLLER CIRCUIT BOARD. THE WINDSHIELD WIPERS COULD WORK INTERMITTENTLY OR NOT AT ALL.
Consequence: IF THIS WERE TO OCCUR DURING BAD WEATHER, DRIVER VISIBILITY WOULD BE REDUCED, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE WIPER MOTOR CIRCUIT BOARD AND COVER. OWNER NOTIFICATION BEGAN ON JUNE 19, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, GMC AT 1-800-462-8782, OR OLDSMOBILE AT 1-800-442-6537.
THIS IS NOT A SAFETY RECALL IN ACCORDANCE WITH THE SAFETY ACT. HOWEVER, IT IS DEEMED A SAFETY IMPROVEMENT CAMPAIGN BY THE AGENCY. VEHICLE DESCRIPTION: 1996-1997 4-WHEEL DRIVE CHEVROLET BLAZER, GMC JIMMY, AND OLDSMOBILE BRAVADA SPORT UTILITY VEHICLES. SOME OWNERS HAVE HAD TO PAY FOR REPLACEMENT OF THE UPPER BALL JOINTS THAT HAVE SEPARATED. GM IS PROVIDING A SPECIAL POLICY TO THESE OWNERS TO COVER UPPER BALL JOINT REPLACEMENT IF THE CUSTOMER FOLLOWED THE RECOMMENDED MAINTENANCE SCHEDULE FOR THE CHASSIS LUBRICATION AND THE VEHICLE STILL REQUIRED THE REPLACEMENT OF THE UPPER BALL JOINTS DUE TO SEPARATION.
Consequence: THIS COULD CAUSE A LOSS OF STEERING CONTROL OF THE VEHICLE.
Remedy: GM HAS DECIDED TO CONDUCT A CUSTOMER SATISFACTION CAMPAIGN TO REPLACE THE UPPER BALL JOINTS ON AFFECTED VEHICLES. THIS SPECIAL POLICY IS FOR A PERIOD OF 8 YEARS OR 100,000 MILES, WHICHEVER OCCURS FIRST, FROM THE DATE THE VHEICLE WAS ORIGINALLY PLACED IN SERVICE, REGARDLESS OF OWNERSHIP. THE UPPER BALL JOINT REPLACEMENT, DUE TO SEPARATION, WILL BE MADE AT NO CHARGE TO THE CUSTOMER DURING THIS PERIOD. OWNERS CAN CONTACT CHEVROLET AT 1-800-222-1020, GMC AT 1-800-862-4389, OR OLDSMOBILE AT 1-800-442-6537, CONCERNING THIS PROGRAM.
ON CERTAIN SPORT UTILITY VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, AND WISCONSIN, AND IN THE DISTRICT OF COLUMBIA. FAILURE OF AN UPPER CONTROL ARM BALL JOINT ASSEMBLY COULD OCCUR DUE TO CORROSION.
Consequence: THIS CAN RESULT IN IMPAIRED STEERING OR STEERING LOSS, OR A PARTIAL OR COMPLETE COLLAPSE OF THE FRONT SUSPENSION, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE BOTH UPPER BALL JOINTS. OWNER NOTIFICATION BEGAN SEPTEMBER 4, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, GMC AT 1-800-462-8782, OR OLDSMOBILE AT 1-800-442-6537.
VEHICLE DESCRIPTION: 4-DOOR, 4-WHEEL DRIVE AND ALL-WHEEL DRIVE MULTI-PURPOSE PASSENGER VEHICLES. DURING DEVELOPMENT TESTING, THE PROP SHAFT CONTACTED THE INBOARD SIDE OF THE FUEL TANK ALLOWING FUEL LEAKAGE. THIS LEAKAGE WAS IN EXCESS OF THE AMOUNT PERMITTED BY FMVSS 301, "FUEL SYSTEM INTEGRITY."
Consequence: IF AN IGNITION SOURCE IS PRESENT, AND THERE IS A FUEL LEAK, A FIRE COULD OCCUR.
Remedy: DEALERS WILL INSTALL ADDITIONAL SHIELDING OF THE FUEL TANK. THIS WILL BE ADDED WITHOUT REMOVING OR DISASSEMBLING THE FUEL SYSTEM.
