Takata re call while driving on secondary street my vehicle lost momentum. Fromm 45 mph to 30 then shut down. The recieved message engine power reduced. It vibrated and shut down. I looked up the code. Sat for a moment and restarted. It went without incident for a couple of days. Had it checked out says it's the throttle body was needed. Is there a recall?

Initially radio stayed on after leaving car once. Later the car would not start even though battery was fairly new. Mechanic diagnosed 2 codes (P062B control micro processor and P0690 relay circuit) related to ECM. Mechanic reset the ECM and tried running car but codes came back again. New ECM had to be ordered and installed.

GMC special coverage adjustment #14159A took an unnecessarily long time to fix(over 6 months) because GM said the vehicle has to consume a certain amount of oil every 1000 miles for them to honor the vehicle. I was forced into driving the vehicle less to avoid causing further damage. The longer duration I drove it the more oil it would consume. Why would I keep driving a vehicle if the problem was identified early enough that I could avoid causing further damage. I was basically told the vehicle has to run out of oil within 3000 miles for them to warrenty sca#14159A. It ended up happening and that problem was fixed but it took an additional 3 months of filling out an oil consumption sheet. Which brings me to my most serious safety concern about the vehicle. Sca#14232A- power steering. I can not get an answer from GM on whether this is a progressly worsening issue within the steering gear or does it fail without warning. Their response is the condition must happen before they will replace the steering gear. According to sca#14232A the condition is the vehicle may have increased friction in the steering system while driving long distances on a straight highway. This could cause the steering wheel to stick in the straight-ahead position. Pretty scary scenario has to happen before they would fix a flaw they already know about in the steering system. A hundred and fifty bad things might happen to me when I get behind the wheel of a car I am not that paranoid to think about them. When the manufacturer suggests something specific and deadly may happen I am going to avoid that situation. May happen is more likely than might happen. Finally, my transmission went up three weeks ago without warning. The vehicle has less than 100,000 miles on it. Ethically I can not sell it even if I fix the transmission and won't drive it.

I bought the vehicle with around 86,000 mi - one owner, from dealership. The engine was making a noise within a couple of months. I have to change the oil every month because of the unusual oil burning issue. It died on me three times. The engine would slow down to a stop. I had to turn it off and back on. Later, after a cold day, I had an oil leak. I took it in and the mechanic said there is a problem with the PCV system and the car has had recalls in the past. I took it to the dealership but they said it was not covered. The diagnosis was rear main seal needs replaced. I found a special coverage bulletin from GM online where it said that certain locations/vins are covered because of the crankshaft rear oil seal needs replacement. Mine was diagnosed with this but when I called GM it said my VIN was not on the list. I have had issues with the vehicle since I bought it. Lots of engine noise, very high oil consumption/burn, and difficult to maintain. I would not recommend this vehicle, and I would encourage owners to file for a civil action if they own this type vehicle because all the reviews lead to the same issue. GM should honor their values by either replacing the parts or recalling these vehicles. I will never purchase a GM vehicle again. The design is great but the engine and system are of very poor quality.

I I changed it. It stalled repeatedly and we had it repaired recently. We also had the oil checked and replaced so GM could track the oil consumption. Unfortunately a month later the car would not start sitting in the driveway, so we had it towed in to a GM dealer. They said the timing chain is busted and they need to pull the engine because there is metal in the oil pan so our oil test is worthless. The mechanic said not changing the oil or low oil levels may have caused the timing chain problem. The estimated cost to fix the current problem is at least $2,300. I'm going to contact a lawyer and see what can be done because this car should have been recalled.

Well first problem was in Sept 2014 mileage on car was 54170 the car had to be towed from my job to dealer came out after working and entire electric system was down could not start or open locks on car with key system at that time they told me the timing chain broke to which they fixed and on receipt they claim they replaced chain gasket and sealant also they claimed they performed a carbon cleaning and did a 27 point inspection now at mileage of 73740 they claim the motor is bad and said it would not last and wanted to charge me $7500 for a new motor when I told them the check engine light came on and would not go out I was told because I went to another place for oil change that was a Firestone place the mechanic claimed the actuators were clogged and claimed the motor was not repairable at that I decided to trade the car in and I did lease another car at the same dealer I know its not their fault the engine did not hold up like it was thought to when I purchased it. While I was waiting for reasons why the light was on spoke to another person and she claimed she had 2 persons who had similar issues so that is why im looking to see if there is a suit in progress

The contact owns a 2010 GMC Terrain. While driving 65 mph, the vehicle stopped accelerating. The contact observed that the antifreeze coolant seal failed and caused the vehicle to overheat without warning. The vehicle was towed to a dealer where it was diagnosed that the piston rings fractured and needed to be replaced. Also, the windshield wipers failed. The VIN was not included in NHTSA campaign number: 09V489000 (visibility). The manufacturer was made aware of the failure. The failure mileage was approximately 124,000.

Catalytic converter will have to be repaired. Failed emmisions testing. By the time I fix this along with the other major parts I know it's 6 years later but this should not be happening. Please strongly consider a recall on this! there are unusual and major issues with the 2010 GMC Terrain please check the internet or pull files of all issue where GMC states nothing was detected. This is an easy way for GMC to get out of recalls. Maybe we need to go to the news and papers.

Requesting a recall on the 2010 GMC Terrain. Mileage that was on the sticker was incorrect. Far from the truth. Major oil consumption, never seen anything like it. Tapping noise was reported @ 3,000 was told it was normal. Knew it was not. Had to replace camshaft, electrical problem, head lights constantly going, never lasting anytime. Will now have to replace transmission and probably engine. GMC stated they have no record of any problems with the Terrain they stated if there were any problems there would have been recalls and that the NHTSA would have done this. Will this be done" not sure how GMC is getting away with this. So many complaints on line. Are there any class action suits for the Terrain? can we start one" there are plenty of people with the exact same problem. Not even similar it's exact.

Catalytic converter going out on a car 6 years old. I know some GMC have had recalls on their catalytic converter, why not the Terrain. I have had so many things fixed on this car. The car started running really rough and hard. The first things caused the car to shut down in power. That was covered under warranty and was fix. Then the air bag light kept coming on, and I had repaired. Then a recall was on that, and I was reimburse my money. Then I had the evap vent solenoid asm and cleared. Still more problems so took it back to the dealership. More money spent as now they said "tested evap system and found gas cap leaking." Repaired that then more money was needed as they said after the light came on again evap purge solenoid leaking pressure.then the compressor went out. I live in Texas so air was needed. Well now the services engine like is on again, and the car idle real hard and jerks like it wants to die. After checking the engine light I was told now it's my catalytic converter, and its going to cost me $1200. After researching I have found other are having the same problem with the 2010 GMC Terrain. These cars and year model appear to be junk. Will there be a recall on this problem" could you are investigate this"

I bought this car 12/2014 in 01/15 I took it in for a noise coming from the engine. It turned out to be the timing chain. It was replaced. In 12/2015 I had engine problems the engine was replaced with help of the warranty I was out of pocket $850. Now 08/16 it ran hot while on the free. I got off a the next exit and took it to Firestone they couldn't tell what was wrong. I had it towed to a mechanic and he replaced the thermostat that didn't work. Had it towed back to the dealership who said something about a battery. That didn't even apply. They sent it back to the people they bought the engine from in 12/2015. They said the timing chain was broke again. They fixed it but it's still running hot. They warranty was voided B/C I drove it off the freeway and the temp reached higher than 280 degrees. They are going to replace the gaskets for $1000 that I have to pa out of pocket and it still might have problems and need another engine. All in less than a year. I refuse to believe this. I believe the dealership either didn't install the engine correctly or the engine was already no god

Check engine light has illuminated multiple times. A rough idle was initial indication something was wrong. I have had the vehicle tested multiple times and have been told from dealership and other mechanics that it is a timing issue. The vehicle will start and drive. Safely problem is while driving through a busy two way intersection, after coming to a complete stop, the vehicle would not accelerate as needed almost leading to an accident. Under normal working condition I would have had no problem making it through the intersection in a reasonable amount of time. It very slowly puttered through the intersection while I had the accelerator pushed to the floor board and after finally crossing the intersection began to accelerate at an unexpected speed. I began to accelerate so unexpectedly that I temporarily lost control of the vehicle and crossed into the incoming lane of traffic.

While entering a freeway onramp, vehicle would not accelerate. Pulled over and waited a few minutes. Started and limped to the nearest dealer. Transmission went out at 41K miles, 5 years "80 days" (Sept 2015) into ownership! dealer did not offer to do an full goodwill repair, despite the low miles and 80 days past the warranty. Engine constantly uses/burns oil. Service documentation available on request.

Ticking noise from engine along with excess oil consumption. Mechanic says this definitely should be a recall. Timing chain will need to be replaced. There is a noise from the engine when the car idles and accelerating. It consumes approximately 2.5 extra quarts of oil between oil changes of 3,000 mile intervals.

The car check engine light won't go out and the onstar rep says it is transmission related to possible timing chain which was replaced aprox 2 years ago at that time there was no warning as the check engine light coming on I travel only highway most of the time and im in fear that the car will stop without notice I feel if the chain is the issue again they should make good on the car it has aprox 71000. Miles at this time and if it stops on highway could be cause for deaths to me or maybe someone else

I was driving down the middle of the road with people behind me, and the car just completely stopped in the middle of the road. The light came on that said stabilitrack. It would not start back up. We had it towed to a dealership, and we contacted GMC, they said our warranty had ran out in December 2014, and this took place February 2015. The vehicle had around 60,000 miles on it. It turned out it was the timing chain, and when it broke it destroyed the whole motor. It actually sheared off some other metal parts. The whole engine had to be replaced, and we had to pay for it all out of our pocket, while we are still paying for the vehicle itself. I feel like that is a problem with the vehicle itself, because you read on these pages and forums, and tons of people have had the same problem as we had. We could have been killed by it stopping right in the middle of the road with no warning at all!!
