1996 Pontiac Grand Prix Problems

What owners report

Complaints for this model year center on brakes, power steering and engine cooling, and many describe failures at relatively low mileage on a car that is now decades old. Brake complaints most often involve ABS warning lights with a low or pedal-to-the-floor feel, while steering complaints describe sudden difficulty turning, especially to the left, in some cases linked to rack and pinion or engine cradle hardware. Several owners also report overheating and stalling traced to cooling-system and engine work.

1. 1
   Brakes

   ABS light on with low or soft brake pedal

   • 14 complaints (18%)
   • typically at 3.1 yrs old
   • filed 1997–2001

   Owners describe the ABS light and low-traction light coming on while the brake pedal sinks toward the floor or feels low and slow to respond. Some say braking was delayed or a popping noise was heard before the brakes engaged, and several report the dealer replaced ABS sensors, calipers, rotors or pads without fully resolving the concern. In a few accounts the pedal went to the floor and the vehicle did not slow as expected. Reported across a wide mileage range, from vehicles under 20,000 miles to well over 100,000.

   What to check: Ask whether the ABS light has come on and whether ABS sensors or the hydraulic unit were serviced; test the pedal feel at a stop and check for stored ABS codes before buying.

   2 excerpts from owner complaints in NHTSA records

   “Front brake rotors are prematurely wearing. When applying brakes at high speed vehicle vibrates, and pedal nearly goes to the floor, causing extended stopping distance. Consumer states vehicle is very hard to stop at speeds over 35 MPH rotors have been replaced 3 times since vehicle was purchased, and need replacement again at the present time.”

   NHTSA complaint #888960, filed 2001-05

   “Was going 30mph & had applied brakes. Vehicle kept going. Low traction light came on. Vehicle hit one curb & then another curb before coming to stop on ramp. Second time at 20mph off ramp. Hit brakes, vehicle failed to slow down. Pressed harder. Abs light came on & stayed. Heard a snap & rotor broke; wheel & vehicle went into spin.”

2. 2
   Steering

   Sudden loss or extreme stiffness of power steering

   • 7 complaints (9%)
   • median 73,499 mi at 14.3 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1996–2016

   Complaints describe power steering suddenly becoming very hard to turn, often when turning left, with no warning and with fluid level normal. Several owners were told the rack and pinion needed replacement, and some were told their vehicle was not covered by the steering recall because of its VIN. In one account the engine cradle bolts had sheared and disabled the steering, and another describes an inner tie rod breaking at low speed. Reported from roughly 35,000 to about 138,000 miles, sometimes at parking-lot or low speeds.

   Recall 03V5270001 related service bulletin

   What to check: Check the steering recall status for the specific VIN, and have the rack, tie rods and engine cradle mounting bolts inspected; ask whether the lower pinion bearing recall work was ever performed.

   “After stopping at a stop sign, lost control of steering while making left turn. Car continued, ran over a mail box and came to rest in a flower bed. When tow truck arrived and picked car up, tow truck driver noticed that engine cradle had fallen down and disabled the steering. Mechanic and insurance adjuster later agreed that the engine cradle bolts had sheared off.”

   NHTSA complaint #10608725, filed 2014-07, 39,153 miles

   “The consumerexperienced intermittent loss of power steering when turning left. A recall was issued for this make/model and year, howeve this vehicle was not included in the recall due to VIN.”

   Engine cooling

   Overheating, coolant loss and stalling

   • 10 complaints (13%)
   • typically at 3.4 yrs old
   • 2 mention a crash, fire or injury
   • filed 1996–2009

   Owners report the engine running hot during normal driving, sometimes with a radiator cap replaced first and head gasket work recommended afterward. Some complaints tie cooling problems to a sudden stall at highway speed, and in one case the heating system stopped working and an engine replacement was recommended. Others describe hesitation or stalling traced to sensors. Appears at both low and high mileage, including vehicles with only a few tens of thousands of miles.

   2 related service bulletins

   What to check: Look for coolant residue or a low reservoir, check the oil and coolant for mixing, and ask whether the head gasket, radiator cap or thermostat has been replaced.

   “I began to have engine problems with my vehicle at 36,000 miles. I decided to trace the VIN # through carfax. When I did I found that the odometer has been rolled back 71,000 miles or more. The car dealer does not want to handle the problem.”

   NHTSA complaint #708017, filed 1999-06

   “Would be driving vehicle when it would start to hesitate at 40mph. Problem was sporadic. Would not be able to pass another vehicle. Took to dealer numerous times for problem. Mechanic could not locate cause.”

   NHTSA complaint #884383, filed 2001-03
4. 4
   Brakes

   Rusting rotors and premature brake wear

   • 6 complaints (8%)
   • typically at 2.5 yrs old
   • filed 1999–2001

   Several owners describe rear rotors rusting and flaking, or front rotors wearing out prematurely and causing vibration and long stopping distances when braking from speed. In some cases pads and calipers were found inoperative, and dealers attributed the condition to limited use rather than a covered defect. Rotors were replaced repeatedly in a few accounts. Reported on cars with low mileage as well as higher-mileage vehicles, sometimes after periods of light use.

   1 related service bulletin

   What to check: Inspect rotor surfaces for pitting or flaking and check that rear calipers are free; ask when the brakes were last serviced, especially on a low-mileage car that sat unused.

   An excerpt from owner complaints in NHTSA records

   “Upon inspection of the tires consumer noticed rear brakes did not operate due to rusted rotors and inoperative calipers/ pads. Consumer has contacted dealer , and dealer replaced the calipers/rotors and pads. Please provide any further details.”

   Electrical system

   Alternator and charging failures

   • 6 complaints (8%)
   • typically at 4.1 yrs old
   • filed 1996–2002

   Owners describe repeated alternator failures, with lights dimming, the ABS light coming on and the car failing to restart after being shut off. One report notes multiple alternator replacements within a short period and a prior campaign involving spark plug wires to handle electrical loads. Others mention intermittent no-start conditions tied to the key security system. Generally reported in the tens of thousands of miles, with one account noting failures every one to two years.

   2 related service bulletins

   What to check: Have the charging system tested under load, ask how many alternators have been replaced, and check that the battery and cables are in good condition.

   2 excerpts from owner complaints in NHTSA records

   “Problem is with factory passenger's key ii security system. Vehicle will most of the time, but will not start at times. The owner's manual states that if this occurs wait three minutes then it will start exactly three minutes later. I have talked with several other people who own the same type of vehicle and have or have had the same problem. I spoke with a service department supervisor at a Pontiac dealer and he stated that he has replaced a barrel full of the key cylinders and not the security system module. …”

   NHTSA complaint #707198, filed 1999-06

   “Vechicle ABS light came on all interior and external lights dimmed, once vechicle was shut off it would not restart. Battery was replaced it worked fine for about 1 week. I was informed the alternator was not putting out enough amps, so the alternator was replaced and 1 week later same problem again so alternator was replaced a 2nd time. That same day the problem was repeated. It seems when the ABS light comes on all the power from the battery is drained.”

   NHTSA complaint #737968, filed 2000-12

Buying note. On a car this old, condition and service history matter more than mileage, so have the brakes, steering and cooling system inspected before purchase. Confirming recall and service-bulletin status by VIN is worthwhile, particularly for the steering rack.
