1996 Buick Regal Problems

What owners report

Owners of this model year most often describe the plastic upper intake manifold failing — sometimes splitting or burning through on startup — and coolant leaking from intake gaskets as mileage builds. A second cluster involves a stiff or grabbing power steering rack, which some owners link to a rack-and-pinion recall for which their vehicle was not covered by VIN, plus repeated brake work such as warped rotors and ABS light flickering.

1. 1
   Engine cooling

   Upper intake manifold cracks or burns through on startup

   • 13 complaints (6%)
   • median 84,058 mi at 10.0 yrs old (10 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2001–2010

   Complaints describe a loud bang or explosion from under the hood when the key is turned, followed by smoke or fire and a hole or split in the plastic upper intake manifold. Owners report replacing the manifold, fuel rail, injectors, lines and sensors; several say the dealer told them their VIN was not included in recall 96V116000 and that they would have to pay for repairs themselves. Reported across a wide mileage range from about 50,000 to 186,000 miles, mostly at startup or shortly after a failed start.

   Recall 96V116000

   What to check: Ask whether the upper intake manifold has been replaced and whether any related recall work was ever done on this specific VIN; listen for an irregular idle or backfire on a cold start.

   “Vehicle back fire through the intake and smoke rolls out from under the hood when trying to start the vehicle, normally start good after sitting over night, but go to start it again it will back fire or the engine idle is very erratic before it will smooth out. I replace spark plug, spark plug wires, cam sensor, pcv valve, fuel filter check battery connection.”

   NHTSA complaint #10269816, filed 2009-05, 90,000 miles

   “After turning the ignition to start the vehicle there was an explosion, the engine was on fire. The fire department was called, and the fire was extinguished. This vehicle was not included in the intake manifold NHTSA recall 96v116000. The EGR valve was inoperative and on another occasion the vehicle had to be jump started.”

2. 2
   Steering

   Stiff or locked power steering, rack and pinion noise

   • 14 complaints (7%)
   • median 81,500 mi at 8.8 yrs old (10 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2000–2015

   Owners describe the steering becoming hard to turn, especially to the left, sometimes locking or failing to return to center, and occasional whining or humming noises from the rack. Some had the lower pinion bearing replaced or the rack serviced after recall 03V527000, and several report the dealer said their VIN was excluded from the recall or that the noise was unrelated. Spread from under 20,000 to over 176,000 miles; a few owners mention it being worse in colder weather.

   Recall 03V527000

   What to check: Turn the wheel lock to lock while parked and at low speed and listen for whine or grumble; ask whether the rack-and-pinion recall was completed on this VIN and whether the rack has been replaced.

   “A recall was issued regarding the rack and pinion steering on our 1996 Buick. The problem was supposedly fixed by the previous owner of the car. My 17 year old son was put in serious danger because the 'fix' did not correct the problem. Now Buick is telling us that they will not stand behind the obvious problem with their vehicle. The car will not turn to the left. Bucik reps are incompetent and rude.”

   NHTSA complaint #10150006, filed 2006-02, 127,000 miles

   “Hard to turn left in my 1996 Buick Regal, steering went tight. Caused me to hit the curb and over the sidewalk, damaging the 2 front tires, rims, radiator, body and under caridge. The police helped me with aaa to get it home, but not sure if it was reported. * cb”

   Air bags

   Airbag deploys without a crash

   • 18 complaints (9%)
   • median 98,000 mi at 10.3 yrs old (9 state mileage, few)
   • 13 mention a crash, fire or injury
   • filed 1996–2019

   Several owners report the driver-side airbag firing with no impact — at startup, while driving, or with the key in the ignition — sometimes causing burns or bruising. Some mention an airbag warning light beforehand or a rubbing noise in the steering column that a mechanic traced to the clockspring wiring. Reported from about 30,000 to 182,000 miles, often within seconds of turning the key or at low speed.

   What to check: Check that the airbag warning light comes on and then goes out at startup, and ask whether the airbag module, clockspring or wiring has ever been serviced.

   “On january 21, 2006 at 7:10 am, while I was driving on u.s. 1, a busy street during rush-hour traffic, my driver side air bag deployed. There was no crash involved nor did my car come into any contact with any object. I didn't even apply the brakes. There was absolutely no reason for the air bag to deploy. When the air bag deployed, it hit me in the face and burned my hand. For about five to seven seconds I did not know what had happened. It was like I heard an explosion and then whoosh, the whole bag was in my face. …”

   NHTSA complaint #10148276, filed 2006-01, 120,000 miles

   “On july 17, 2019 at 8:40am, I got into my car in my driveway. I turned the key in the ignition and the airbag exploded. (the car was not started.) the airbag sounded like a shotgun being fired and a powder like substance immediately filled the car. The airbag itself hit me in the abdominal area. I found the door handle, opened the door, and rolled out of the car onto the ground. At this time, I yelled for my son. My son picked me up off the ground and called an ambulance due to me being in a severe amount of pain and in shock. …”

   Engine cooling

   Coolant leaks at intake manifold gaskets

   • 11 complaints (5%)
   • median 72,000 mi at 8.0 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1999–2008

   Complaints describe coolant disappearing with no obvious puddle, a leak near the upper intake manifold, and antifreeze mixing into the oil or burning as white smoke. Owners report gasket replacement, sometimes more than once, and one notes the dealer covered part of the cost because the failure happened early. Typically reported between roughly 50,000 and 130,000 miles, with repeated failures at intervals.

   What to check: Check the coolant level and look for white residue or seepage at the intake manifold seams; ask for service records showing gasket replacement, and check the oil for a milky appearance.

   “Buick Regal 1996.engine and engine cooling:cooling system hortly after just 72,000 miles, a leak developed near the upper intake manifold, causing excessive coolant loss (up to 1 gallon per week). I believe this to be a saftey hazard resulting from a design flaw. The owner's manual includes several warnings that coolant contains ethylene glycol that will burn if it comes in contact with hot engine parts. I am also concerned this problem may have caused engine damage that will manifest itself later. …”

   NHTSA complaint #10038642, filed 2003-09, 72,000 miles

   “My 1996 Buick Regal has had two intake manifold gasket failures--one at 52,000 miles, and the most recent, at 111,000 miles. In the first instance, the local Buick dealership refunded half my money of the cost of the $607 repairs because they agreed that it was highly unusual for a gasket to fail at such low mileage. My son, who did the most recent repai andr is a materials science engineer, inspected the most recent failure and found several places on the gasket where it was deformed and had let antifreeze escape. …”

   Brakes

   Brake rotor pulsation and ABS light flickering

   Mentioned in 4 of 60 sampled complaints

   Owners describe noisy, out-of-round rotors and pads requiring turning or replacement, rear disc brakes replaced more than once, and ABS warning lights flickering on and off. One complaint describes a brake pedal going to the floor after a fire in the engine bay. Reported from around 15,000 to 30,000 miles in several complaints, with others at higher mileage.

   Recall 96V0690001 related service bulletin

   What to check: Feel for pedal pulsation or vibration when braking from highway speed, and confirm the ABS light does not flicker; ask whether the front brake line routing recall was completed.

   “I purchased my car in 1998 and soon after that the paint started to peel. In about 2000 I finally researched it online and found out to look at my VIN number, and if the 11th number was a '1' that it was painted in canada and that they trouble with bad primer up there. A lot of people had sued for a new paint job. Gm closed that plant down. I went to maaco here and was told that since the primer was bad, they would have to strip that all off too, and the whole job was more than I could afford. …”

   NHTSA complaint #10235436, filed 2008-07, 30,000 miles

   “While merging onto the freeway, I was taking my car to be smogged. At speed, I noticed a little white puff of smoke emit from the right side of the engine bay. As I proceeded to start moving to the shoulder, this puff had turned into a gray plume. As I finally reached the shoulder, the entire front of the engine bay was billowing black smoke. As I tried to stop, the brake pedal went to the floor, so it seemed the fire had burnt through a brake line. I managed to engage the emergency brake slowly and managed to stop on the shoulder. …”

   NHTSA complaint #10786585, filed 2015-10, 195,000 miles

Buying note. This is an older vehicle where cooling-system and intake work history matters more than mileage, so ask for records on intake manifold and gasket repairs and on the steering rack recall. A pre-purchase inspection covering the steering, brakes and airbag warning system is worthwhile given what owners describe.
