Driver side intake manifold butterfly valve came loose and the screws went through the engine. Recently the butterfly itself got stuck and leaned out and ruined my O2 sensor and idle air controller

I was accelerating onto a super highway when my vehicle engine light came on and the engine started running rough. When I returned home I put my engine scan on the computer and it stated egr valve....I believe it may have been a P0401 code. I ordered a new egr valve and replaced it along with numerous gaskets and cleaned everything according to my service manual......which by the way, is the $100 shop service manual the dealership uses! it corrected the problem for about 6 months time period and then began all over again. I use premium shell gasoline in the vehicle and do preventative maintenance on a regular basis as described in the service manual. I have done significant research online and have found numerous complaints regarding this issue however, Suzuki has not responded with a solution. I see Ford and some others had this similar complaint and redesigned their egr valves to resolve the issue. Also, I have received several Suzuki recalls however, there are no Suzuki service centers in America now to get theses issues resolved. The latest recall was sent to me from Suzuki stating the issue and that they would notify where to get it resolved......soon?? never heard another word! this is like 2-3 recalls now.....air bags, power steering pulley, and several others. I did have the ABS brake sensors and the transmission lock issues resolved at the dealership shortly after my purchase of the new vehicle however, the rest have been unresolved! this egr valve is either a defective engineering issue or related to ethanol added to the gas which is the biggest nightmare ever for any engine and should be stopped immediately as any mechanic will tell you!! it was a money maker for the ultra rich and nothing to do with resolving emissions or anything else as a defective egr will spew more pollution than not having it at all! updated 09/21/15

While driving, belt tensioner seized breaking belt and over heating car. Both belt tensioners have been replaced. There is a recall for the power steering/fan tensioner. Not for the water pump/alternator pulley/tensioner.

The contact owns a 2006 Suzuki Grand vitara. The contact stated that the vehicle failed to start. Once the vehicle was started after several attempts, the check engine light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed that the egr valve was defective. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 75,000 and the current mileage was 88,600.
