“Odometer Fraud. The contact purchased a 2011 GMC Terrain. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale.

“Ok so my 2011 GMC terrain just went over 150,000 miles I bought this vehicle used from a dealership not knowing that there was a big lawsuit or that GMC continuted making this make and model knowing that it had a oil usage problem. So mmm mmm with that being said let's start with my vehicle uses oil, my vehicle idles high low and always rough at times, my service stabilitrak flashes, my motor sounds like a HEMI kock knock knock instead of a 2.4, doesn't matter where I'm at or where I'm going I let off of the gas and my car dies.... Let me clarify on that last one me and my 9 year old daughter we're headed home today let off the gas to go around a curve and a hill and you guesswd it my 2011 GMC TERRAIN died I lost all control and all power had no power steering and no brakes... I just thank Jesus I wasn't speeding and that there was no oncoming traffic cuz I don't think me nor my 9 year old would have made it out ok. So thanks to whatever faulty motor engine or power train GMC has with this make and model putting people's safety and lives in danger due to these issues and only choosing certain VINS eligible instead of all VINS from 2011 GMC TERRAINS in my…”

“I have owned this car for a little over year and have had nothing but issues. The car started on fire with an electrical issues once, the car has just stopped running on me multiple times while I was driving, almost causing a wreck. The engine goes through Oil like crazy. I've had it back to the dealership multiple times and never get a fix. I believe this vehicle is a true lemon.”

“The failure point was the seal on the sunroof and the sunroof itself. A correct failure mode would be for it to leak into the cabin thus being immediately visable. Instead, an internal seal apparently failed allowing the intruding water to flow unobserved into the bulkhead region between the car body and the internal liner of the vehicle. As a consequence it flowed down a side post exiting into the dashboard and control panel. The dashboard shorted out elliminating the turn signal indicator (and possibly the turn signal itself). The radio and amplifier and the general alarm system went to maximum volume. Fortunately, it did not short out the airbag, thus it did not deploy while I was on the freeway, maybe next time. The salient point is that water was allowed to intrude through the sunroof and able to proceed unobserved to the back of the dashboard. The inside of the car was removed and replaced as was the major components behind the dashboard. The airbags were not replaced.”
