“I have leaky intake valve gaskets on a 2001 Oldsmobile Silhouette van which has ruined the ehgine. Gm will not do anything. I have many friends who have had the same problem. There are thousands on the internet who report the same problem in the 3.4 v6 GM engine.”
NHTSA complaint #10106154, filed 2005-01, 30,000 miles“Engine knock on cold start - we have brought our 2001 Oldsmobile Silhouette in several times complaining of an engine knock on cold start. Sometimes the knock will go away in a few minutes, other times it lasts much longer. The most recent visit we were told that GM is aware of the problem, but does not believe this engine knock will cause long term damage. We believe otherwise. We purchased the vehicle knew and began reporting the problem when there was only 20,000 miles on the vehicle. …”
NHTSA complaint #10036676, filed 2003-08, 22,994 miles“This Oldsmobile Silhouette has had so many many problems over the past 3.5 years, I have finally had enough. I noticed an occasional engine whine or rattle while driving, but it was so sporadic I wasn't sure if it was really happening. Then last week it seemed as though the heat wasn't working well in the van...the temperature wasn't below freezing, but the heat just wasn't warming up sufficiently. I mentioned this to my husband and he noticed it the next time he put the heat on, too. At the same time he noticed that the engine termperature was fluctuating as he drove and stopped. …”
