On October 13, 2023, I was driving on the highway when my 2014 GMC Terrain power was reduced. Suddenly, the engine light came on and car began throttling. Second, an error message appeared on my dashboard indicating “ engine power is reduced.” Then it stopped in the middle of the highway. I was able to restart my vehicle and drove it to a nearby mechanic shop. The mechanic said the problem was my timing chain and that my vehicle was not drivable. I left my vehicle at the mechanic shop because it was the weekend and It needed it to be towed to the dealership. On Monday, October 16, 2023, I had my vehicle towed to Buick Classic Service Center. After waiting for two days, I received a call from the service center stating that my 2014 GMC Terrain timing chain and pressure gas pump was the cause of the problem - with my vehicle. After, reading other owners similar complaints ; why is there not a recall to address this problem? Now, I am stuck without a vehicle and the company has no idea how long it will take to get the parts needed to fix my vehicle. I was told that the timing chain and a tension is on back order due to the employees of GMC being are on strike.

My engine Burns a very large amount of oil rapidly. I have to replace oil in the engine at least twice a week. I went to the Automotive Service Center and they indicated that my timing chain need to be readjusted and that the engine itself between the year of 2010 and 2017 on gmc terrains have major problems/ defects in with the engine. I was driving on the highway and the car slowed down I barely could get any acceleration. I then had to get off of the expressway to avoid collisions. I took my car to the shop several other times for automatic brake system problems and stability track problems. I had censors replacedvand stability track problens. They wrre fixed but the automotive technicians indicated they the oroblems will happen again. Soon after that my engine was low of oil again within the matter of two or three days. The problem (massive oil consumption) continues to happen. I have investigated the problem and I found that there were engine class action lawsuit on the GMC 2014 Terrain because of the engine problems. I need to know how I can get my problems with the engine in particular resolved so that I can move forward and not worry about being involved in a motor vehicle accident when I drive to work each day.

"SERVICE SIDE DETECTION SYSTEM" WARNING UPON STARTUP AND SPORADICALLY WHEN DRIVING AT NORMAL SPEEDS. THE BLIND SPOT MONITOR LIGHTS IN THE SIDE MIRRORS DO NOT FUNCTION ANYMORE. UPON STARTING THE VEHICLE, BOTH SIDES USED TO ILLUMINATE WHILE RUNNING THRU SYSTEMS CHECK. NOW ONLY THE DRIVER'S SIDE LIGHTS UP. TO CONFIRM, THE BLIND SPOT MONITORING DOES NOT WORK FOR EITHER SIDE OF THE VEHICLE NOW. THE SENSOR IS UNDERNEATH THE REAR BUMPER COVER, EXPOSED TO THE ELEMENTS. THERE ARE SEVERAL FORUMS MENTIONING THIS ON THE GMC TERRAIN DENALI MODEL ALONG WITH CADILLAC AND CHEVROLET MODELS THAT HAVE THE SENSOR IN THE SAME PHYSICAL LOCATION OF THE CAR. THE SENSOR IS EXPOSED TO RAIN, SNOW, DIRT, DUST, MUD. I HAVE CHECKED RECALLS ON THIS BUT IT DOESN'T APPEAR TO HAVE ANY OUT THERE DESPITE FORUM COMPLAINTS. THERE SEEMS TO HAVE BEEN "SERVICE BULLETINS" SENT OUT FOR CADILLAC AND CHEVROLET MODELS DUE TO CUSTOMERS COMPLAINING ABOUT THIS SAME ISSUE. THOSE HAVE BEEN REPLACED AT NO COST TO THE CONSUMER FROM WHAT I UNDERSTAND. AFTER DOING SOME RESEARCH, TYPICAL COST FOR THIS PIECE DIRECT FROM ONLINE SELLERS IS $250+. TO HAVE THE DEALER REPLACE, IT'S LOOKING AT A COST UPWARDS OF $750+. THE NUMBER OF TERRAIN DENALI (THE ONLY TERRAIN TRIM WITH THE SIDE BLIND ZONE ALERT) ARE RELATIVELY LOW COMPARED WITH THE QUANTITY OF THE CADILLAC AND CHEVROLET MODELS WITH THIS ISSUE. I'M WONDERING IF THIS IS POSSIBLY WHY THERE WERE NO "SERVICE BULLETINS" ON THE TERRAIN. THE TERRAIN HAS A HORRIBLE BLIND SPOT AND I UTILIZED THIS FEATURE ALL THE TIME WHEN IT WAS WORKING PROPERLY. I FEEL LIKE SAFETY IS COMPROMISED FOR MYSELF AND MY FAMILY WITH THIS NOW NOT WORKING. I APPRECIATE ANY AND ALL ASSISTANCE.

DRIVING BETWEEN 40-45MGH AND STABILITRAK FAILURE SERVICE AND ABS FAILURE LIGHT COMES ON. AT EVERY BUMP THE SERVICE LIGHTS GOES ON AND OFF. THEN ON A SMOOTH SERVICE THE STABILITRAK LIGHTS COMES ON UNTIL I GET HOME. WITH THE COLLISION WARNING TURNED ON THE CAR ALSO AND ALMOST FREQUENTLY TENDS TO BRAKE ON ITS OWN WHILE DRIVING. BUT HERE'S THE REAL PROBLEM THIS 2014 GMC TERRAIN DENALI CAR IS NOT ON THE 'RECALL' LIST - WHY? SEEMS IT'S FROM THE SAME CAR MANUFACTURER WITH SAME ISSUES, SHOULDN'T IT BE ON THE SAME RECALL LIST.
