3. 8l engine intake manifold leaked, causing engine coolant to foul spark plugs disabling the vehicle.

Initiation of problem started 19 sept 2003 while on a roundtrip, TX to CA. After approximately $3,200 in repairs, CA & TX, the culprit is identified and the problem is currently fixed (30 oct 2003). The culprit is a warped upper intake manifold, which allowed coolant to leak into the cylinders (finally hydro-locking the engine). This hard-plastic, domed original gm part has about a 1-mm warp on the end nearest cylinders #1 & #2. I consider this to be a manufacturer's flaw, although the vehicle has more than 75,000 miles. The TX dealer has seen other problems like this. A gm/Buick representative does not want to consider sharing some of the repair costs. I have a thorough file on this problem. I note other complaints for this integral part of the engine. -- jack sanders, dallas.

The plastic upper intake manifold developed an internal crack, which leaked coolant into the combustion cylinders. The 3. 8l v6 engine shut down and then hydrolocked. It was repaired by a certified Buick dealer. The day the vehicle was returned, within 20 miles of driving, the rear main bearing seal failed. The dealer felt it was caused by the coolant mixing with the oil. After this repair, the engine ran approximately 2000 miles and spun a main bearing, due to the coolant/oil mixture. This has been reported to Buick. They feel it is not their problem.

The plastic intake manifold developed a hole and leaked anti freeze onto the cylinder. This resulted in engine locking up and the crank shaft bearing going bad. The rod bearings also failed due to water entering the oil pan.

1999 Buick Park Avenue. Consumer writes in regards to defective plastic manifolds and requests reimbursement for two engine repairs. The consumer stated on July 28, 2003, the vehicle stopped running and again on November 13, 2014. The consumer stated both times, the manifold had to be replaced.

Consumer stated that vehicle overheated and broke down on highway. Dealer diagnosed that the plastick intake manifold cracked, causing failure.

While driving the vehicle stalled and the check engine light illuminated. The vehicle was taken tot eh dealer where it was determined that the engine intake manifold had a design defect which caused premature gasket failure. That failure caused coolant to leak into the engine manifold and burn in the engine. The vehicles a/c compressor also failed.

Intake manifold has malfunctioned. Dealer notified.

When the consumer attempted to start the vehicle a loud explosion occurred. The explosion destroyed the upper intake manifold plenum, fuel rail and fuel pressure regulator. The consumer paid to repair the engine and other damaged parts. The dealer and manufacturer refused to reimburse the consumer for the repairs. The manufacturer has not determined the cause.

The engine exploded upon starting the vehicle. There was damage to the upper intake manifold (plenum), fuel injector rails, and fuel pressure regulator. All componets required replacement, plus a seal and valve kit. Both gm and the dealer refused to reimburse for the cost of the explosion and subsequent damage/repair.

Anti-freeze leaked into the engine's oil. As a result, the vehicle lost power. The rod bearings, upper and lower intake manifolds were replaced. There was severe damage to the engine, which caused the entire engine to be replaced.

Lifters damaged from apparent coolant leak in upper intake manifold at 80,000 miles. Rod bearing knock occurred at 81,820 miles. Cause as yet unknown. Possibly related to earlier coolant leak problem. Now in need of a new engine.

The intake manifold was a defect from the manufacture. The manifold allowed water to leak into the engine causing the engine to stall. Ph.

Intake manifold failure.

Consumer states that the intake manifold began leaking antifreeze in the vehicle's engine. Dealer replaced and the problem occurred again. Ph.

The first incident of this problem occurred in 2001 at 48,000 miles. To correct the coolant loss the upper intake manifold had to be replaced at a cost of approx. $500. 00. The second occurance was at 103,000 miles, this time gm had issued a technical bulletin no. 01-06-01-007a describing the problem and indicating that now both the upper and lower intake manifolds need tobe replaced to correct the problem, cost $750. 00. It is my feeling that since gm knows the problem is one of faulty material they should cover at least the cost of the parts, which they have failed to do. Dt.

Intake manifold developed a crack or hole. Coolant leaked into cylinders and oil causing engine not to run. Repair cost $966. 23. Fuel regulator failed causing engine to back fire and blow vaccum hoses off of engine. Replacement of same cost $114. 94. Dt.

Engine coolant dex cool leaked into engine through defect in upper manifold, destroying entire engine, requiring complete new engine.

Intake manifold leaked coolant fluid all over the engine. This resulted in the vehicle stalling while driving . The manifold was replaced, but the problem recurred. The dealership replaced the manifold with a redesigned one.

Intake manifold developed a crack or hole. Coolant leaked into cylinders and oil causing engine not to run. Repair cost over $900. 00. This appears to be a known problem and Buick did not offer to share any of the repair expense. The plastic manifold, was over $300 for the part, which should have not failed, or at least should have been cheap to replace since it was plastic. This is a long term know defect and Buick should have recalled this and fixed it in the newer vehicles.

While traveling at highway speed low coolant message flashed on while low temperature gauge was reading cool. Soon after, noticed engine running hard. Consumer pulled vehicle over, and engine stalled and would not restart. Dealer found plenum leaking, dealer replaced intake manifolds upper and lower, plenum, coolant bypass hose, and head gasket seal.

Crack in plastic cover of the manifold/emission system. There was a pop and the parking area filled with black/blue smoke. Car would not start after the incident. TSB sent out about this problem, vehicle 36th month outside the warranty period. Referenced in ea02-030.

While driving on the interstate engine check light began flashing, and chimming. Pulled over to side of road stopped and raise the hood. The engine was running rough. Stopped the engine saw that it was not overheated. Attempted to start. It wouldn't. Wrecker tooto brian harris dealer. Dealer repaced both intake manifolds because they were pitted and allowed coolant to enter into cylinders and lock the engine. Dealer said both manifolds had to be replaced.

While driving about 55 mph warning light for coolant came on. Consumer went to mechanic, who found upper manifold plentium, which was made of plastic, had allowed antifreeze to flood engine.

Plastic case on intake manifold - holes burn through case and water goes into cylinder.

2003 Buick Park Avenue. Consumer states possible safety defect with the intake manifold and gasket. The consumer received a call from a GMC executive assistant. The consumer stated his concern was dismissed because the vehicle was not taken to an authorized dealer for the repair when the problem occurred a second time and was out of warranty. However, both technicians who repaired the manifold and gasket within a two year period stated the replacement parts were substandard due to them being made of plastic and had degraded.

1996 Park Avenue with manifold gasket issues**.

Crack developed in the manifold as well as in the upper intake plenum.

The plastic intake manifold melted, and caused coolant to leak onto the engine. Scc.

Vehicle overheated twice within a 2 month period. Coolant elbow broke when vehicle overheated the first time. The second time the vehicle overheated, the upper intake manifold broke.

The intake manifold exploded, which caused a loud noise and smoke to appear.

Symptom of battery failure-triple a jump started car -checked battery & engine with computer which detected no problem-drove car @ 50 miles on highway-no problem- after sitting over nite started normally but after driving about 2 miles lost all power- tripe a could not start so towed car to their shop & found engine froze up- caused by defective air intake manifold which developed a leak allowing coolant fluid to get into engine mixing with oil. I know of 5 other incidents of this nature, 3 of which resulted in engine failure.

The vehicle would not start. The vehicle was taken to the dealer and when the technician started the vehicle the manifold blew up resulting into engine fire.

The vehicle has a problem with the design of the manifold system which cracks and can causes the release of noxious gases. Nlm.
