Montana V6

  • Automatic transmission
  • 125,000 miles

This is the second time in 3 1/2 years the intake gasket has to be replaced. The costs were between 450.00 - 550.00. Our mechanic has called GM several times and reported this as a defect to no avail.

Montana ES

  • 68,000 miles

found out at 75,000 miles that at 68,000 my intake had cracked. Talked to several mechanics including a GM parts person (off the record) and have been told there are major problems with the plastic intakes cracking. Each of these certified individuals feel this is a manufacture defect. I don't understand why GM is not recalling these intakes. I spoke to GM at least 5 times and each time they told me they could not help me with my repairs. So, I won't be helping them by purchasing another Pontiac or GM product, so THERE!!!!!

My wife wanted this Montana...P.O.S.....Never cared for Pontiac products and now I know why...It was a gut feeling.....Starting loosing the coolant and then it got into the oil....I tore into it and found a failed intake gasket....It was the rear gasket...What a surprise....I have had no problems with this vehicle other than the gasket but it is enough for me to never buy another Pontiac product EVER...Hey GM I want my money back......I mean we all want our money back.....

My 1999 Pontiac Montana gets very hot and sometimes overheats. After reading some of the other complaints online, I am in the exact same situation as everyone else with the cooling problems. I would not buy another GM product if they can not own up to their failures. I will surely by a Japanese car!
