Consumer Description
As per several other complaints on the GMC terrain of particular years my vehicle has had a rear main seal leak, a blown engine terrible amounts of oil consumption and now the second engine has malfunctioned. And made the vehicle inoperable. The safety of myself and others was put at risk as the vehicle lost all power and cut off. The problem has had class action lawsuits filed. The first time the engine failed no warnings came on the second time a reduced engine power came on that we had no idea existed. The vehicle consumed oil very quickly, with in days the oil could need replaced. Oil consumption has been going on for years. Even after replacing engine.
