Pontiac G8 Engine problems by year

Right side oil leak from the valve cover, leaking onto the exhaust manifold @20000 miles. Fire concern.

Hello, I am writing to you today to inform you of a common and known issue with all gm ls engines that come with active fuel management (afm) or displacement on demand (dod). The lifters in the engine begin to fail somewhere after 40,000 miles - with this particular issue occurring in my own vehicle at just over 61,000 miles. If you were to google "ls dead lifter", "ls lifter failure" or "gm piston slap", the issues arises. I have contacted the pontiac division at gm to complain about this, but they said that...

Tl* the contact owns a 2008 pontiac g8. While driving 40 mph, the check engine indicator illuminated. The dealer diagnosed that the timing chain was stretched and needed to be replaced. The vehicle was not repaired. The failure mileage was 94,000.

A tapping noise was heard when the engine was running - whether the car was at idle or moving. The tapping would not cease. The vehicle was taken to the dealer, where they discovered that the #2 valve lifter had collapsed into the camshaft and damaged the camshaft. All 16 lifters, camshaft and associated gaskets were replaced. Had we continued driving the car, more defective lifters would have collapsed, causing the engine to seize. At that point, the engine would have to be replaced. The lifters are defective in all gm cars with this engine (see service bulletin 10-06-01-007d).

Tl* the contact owns a 2008 pontiac g8. While driving approximately 70 mph, the vehicle stalled and the check engine warning light illuminated. The vehicle was taken to the dealer where it was repaired on several occasions, yet the failure kept recurring. The vehicle also exhibited multiple failures with the ignition switch and electrical system that recurred intermittently. The manufacturer was made aware of the failures. The failure mileage was unknown.

I am investigating a fire , the cause of the fire was a 2008 pontiac g4. After the owner drove the car he parked it in his garage. Within 20 min. Of parking the car it was on fire in his garage. The fire looks to have started in the engine compartment of the car. This fire burned his house down and injured him. I am looking for any information that I could use in my investigation involving fires related to pontiac g4 2008 models.. This information will be used for fire dept use in confirming the cause and...

Upper radiator neck snapped off of radiator, allowing upper radiator hose to separate from radiator. All coolant escaped causing engine to immediately overheat. "Engine extreme overheat" light on dash came on. Gm says not covered under warranty. This is evidently a common problem with these cars, and the similar 2004-2006 gto as evidenced by all the threads on the subject on grrrr8.Net and g8board.Net. This should be a recall. Just glad this did not happen on the highway as coolant between the tires and the road would have caused a messy wreck. *Tr

Tl* the contact owns a 2008 pontiac g8. The contact stated that while driving 50 mph, the vehicle stalled without warning. The failure recurred twice. The vehicle was towed to the dealer for diagnosis, but the dealer was unable to duplicate the problem. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 60,000. *Tr

I was driving down 95 south near baltimore at about 70mph at 7am this morning when my 2008 pontiac g8 gt (with the l76 6.0Lv8 engine) alerted me that the engine was hot. I immediately pulled over and when I popped the hood I saw the upper radiator hose was not attached to the radiator anymore and a lot of coolant had leaked everywhere. Upon closer inspection, I saw that the pastic radiator flange that the hose attaches too had broken off of the radiator and was in the hose. Since the engine cooling system, which...
