Buick Problems

Intake Manifold Gasket May Leak Coolant or Engine Oil

Engine -- Verified

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Erratic Fuel Gauge Operation

Electrical & Lights -- Verified

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has extended the warranty on the fuel level sensor to 10 years or 120,000 miles, agreeing to pay 50% of the repair cost. Please contact your local GM dealer for more...

Intake Manifold Gasket May Develop Engine Oil and/or Coolant Leak

Engine -- Verified

The intake manifold gasket may develop external engine oil and/or coolant leak. The intake manifold will need to be removed and the gasket replaced to correct this issue.

Rear Suspension Low Due to Failed Air Compressor

Suspension & Steering -- Verified

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure

Engine -- Verified

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

Buick Recalls (Recent)

Second Row Seat Side Trim May Restrict Safety Belt

Body, Interior & Misc., August 18, 2010
RepairPal Expert Overview:

When moving the seats from a flat to upright position, the second row seat belt buckle may bind on the second row seat trim shield. This could prevent proper operation and securing of the safety belt, which would increase the risk of injury to an occupant. Dealers will modify the second row seat trim shields. The GM recall number is N100243. This recall began on August 18, 2010.

Buick Enclave

Possible Under Hood Electrical Fire

Electrical & Lights, June 11, 2010
RepairPal Expert Overview:

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

GM Recalls 2010–2011 Vehicles Due to Contact Between Starter Cable and Power Steering Line

Electrical & Lights, November 4, 2010
RepairPal Expert Overview:

General Motors is recalling 2010–2011 DTS and Buick Lucerne models with V8 engines due to contact between the starter/alternator cable and the power steering return line. This can result in a worn power steering return line, which can cause a power steering leak, possibly resulting in a loss of power steering. This can lead to an increase in the risk of a crash and/or an engine compartment fire. Dealers will secure or reroute the necessary lines, free of charge.

Buick Owners' Stories

I love my Buick and it operates great. I had to have the catalytic convertor replaced about 3 years ago and it's been okay. Now for no reason it cuts off and I have to put it in neutral and recrank. It cranks fine, but it's very scary when I'm traveling alone. Computer shows nothing is wrong and naturally it won't do it when my mechanic drives it. Unpredictable! Help.

I BROUGHT MY TRUCK IN 07 AND SINCE THEN I HAVE PUT ON 6 WHEEL BERRINGS AND I AM TRIED THEY KEEP SAYING THERE IS NO RECALL BUT SOMETHING IS WRONG.

My 1995 trunk keeps leaking but i cant figure out from where. When it rains, the trunk fills up with wanter and the carpet is always wet and stinks like mold. How can i find the leak? The seals look good,.

I have 149,000 miles on my 2004 Buick Rendezvous and I have not experienced any major problems. Oil changes, brakes and tires have been my only major expense. I was impressed how well it handled in snow and I only have front wheel drive. Excellent gas milage and the third seat has come in handy on many occasions.

I like the feature of the seats folding forward or being able to remove them for additional storage space.

Buick 1998 Lasabre 160k miles EMISSIONS AZ
Emissions +++ Emissions++++++++++
Arizona== Great used car but weird situation, it does not fail but it does not pass emissions. all lights on dash turn off after starting car so no problems according to car.
inspections says: catalyst, EGR and evap system NOT READY
and misfire, O2 sensor, ,heated O2, fuel system and component READY
dealer says Do a drive cycle which means drive it for 100 miles or more for computer to give new results but after 700 miles driven , still the same results.
if this happened to your car how did you fix the problem to make it pass emissions?
