I have had many problems relating to this vehicle, for only owning it for a year. Inaccurate Fuel Gauge Reading- My fuel gauge is inaccurate. It has resulted in my vehicle running out of fuel and stalling, while on road. I have 4 children who are at risk of danger while in vehicle.The fuel warning light has illuminated when the gauge needle says I still have more than plenty of amount (a quarter of a tank or more at times. It differs). I have taken to many shops, it was diagnosed with an electrical and fuel system failure. Electrical shorts and problems- Having electrical shorts on and off. Check engine light comes on/off Vehicle randomly failed to start with no good reason/cause. My vehicle was difficult to start and would require several attempts before starting. Power lock/unlock fob doesn't work, replaced battery multiple times. My windows and sunroof power windows do no work and unable to fully close on/off at times. Check airbag light has been coming on and off. Power Train intermittently, the transmission shifts with a loud thump, at various speeds. Vehicle starts shaking and jerking while shifting gears and going different speeds. My vehicle slows down, power reduce engine and steering difficult at times. Other/ water leak- Found water in all of my tail light assemblies, headlight assemblies, sunroof and windows leaking. There is no proper seal or has worn off, causing leaks in and repairs for many replacements, which are expensive temp fixes with no permanent solution. Causes accidents by not having necessary working equipment for driving conditions. Other:Hood doesn't latch and stay open so difficult to even check fluids properly alone. Multiple dealers have inspected problems, some have not been able to pin point the problem for some of these issues or have been charged unaffordable amount before fixing, and only diagnosing problem. There are recalls out for many of these problems and my vehicle needs to be on the list for serious safety issues!

Frame is severely rusting, especially on the driver’s side. Vehicle has only approximately 75,000 miles and has been well maintained. Purchased new by my Father and when he died, it was passed on to me. I feel it may becoming unsafe to drive.

For the third time, the brake booster has failed on our GMC Terrain. We had the first replaced with an OEM part. That booster failed after 2 weeks. A second OEM brake booster was installed. That one lasted about a year until it failed as well. This time we were traveling down the interstate and interstate speeds. There were no indications of an issue until trying to slow down when attempting to exit the interstate. Luckily it was a long ramp and there was not much traffic as I had to push extremely hard to slow down the vehicle. Knowing immediately what had happened, we noticed a GMC dealership was just down the road and safely made it. We left the vehicle at the dealership and rented a car to continue our vacation. We are now being told that not only did the brake booster fail, but the components entered the engine and caused major damage. The suggested repair is a full engine replacement. This is unacceptable for an issue that GMC has know about and has had recalls for on other years of their vehicles. Not only could my family have been severely injured, or worse, we are not financially able to repair the vehicle.
