*The service transmission message coming on and the vehicle goes into neutral and stalls, service transmission light comes on while on highway and the vehicle goes into park and loses power and stalls, All wheel drive message coming on, traction light coming on, going about 74 mph on highway and speed gauge dropping, low fuel light coming on even thought it has 3/4 tank of gas. *I almost got ran into from behind twice when the vehicle went into neutral and into park by an 18 wheeler truck as I was trying to pull over onto the shoulder of the highway. *Confirmed by LaFontaine in Ann Arbor, MI *Vehicle has been inspected by LaFontaine in Ann Arbor, MI. Found bulletin 19-NA-181 which was very close to all symptoms and stated to check for chaffed wires near the ECM. Found no spots in the tape where it was rubbed through but lost comms when wires were shook. Unwrapped main engine harness loom and inspected wires, found nothing. Started TAC Case # 9-6385087421 and was told it probably is a chaffed comms wire somewhere and gave me multiple locations to check. Found no damaged wires in those locations and shaking main harness no longer would make it fault. Put it all together and drove it down the road and faulted immediately. Unwrapped main harness again snd sprayed with saltwater to help conductivity but still couldn't get it to fault while shaking the harness. Only way it will fault is when shifting into drive the drive train bumps just right to bend the right wire. Checked every wire I could find and can't find the problem wire. Not drivable. When this vehicle faults it will not shift past 1st gear and sometimes locks out reverse. Must be towed. Needs the main wiring harness to start, recommend customer to authorize FSE to dealership CUST declined. *Yes, all the lights and messages were coming on over the dash.

ENGINE
For the last 6 months my vehicle has excessive oil consumption 1/4 to 1/2 quart of oil every week. When it starts up it sounds like a diesel engine. In 2019 it did the same using about a 1/2 quart every 3 weeks. We have kept an eye on it ever since as over time it has increased oil consumption and just recently found out this is a problem for many others as well. We have always kept the oil changed when due per mileage sticker and vehicle oil life indicator.

VISIBILITY/WIPER
1. The component that malfunctioned was the wiper transmission and it is available for inspection upon request. 2. A thunderstorm came while driving in the vehicle. The windshield wipers were turned on and by the third rotation the wiper just stopped. It was a heavy rain and there was no visibility. The hazard lights were put on and the vehicle was slowly driven to the side of the street, where it was safe to wait. Other vehicles blew horns and gave quick flashes high beams as the vehicle was driven to the side of the street where it was safe. There the hazard lights were on and the wipers did not work. There could have been an accident because the wipers malfunctioned.

The contact owns a 2011 GMC Terrain. The contact stated while driving at an undisclosed speed in the rain, the front windshield wipers were activated from low to high however, the wiper blades went up and failed to go back down. The contact pulled the vehicle over to the side of the roadway and waited for the rain to stop for the contact to manually push the wiper blades down. The contact attempted to activate the wipers however, the wipers were inoperable. The vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 144,000.

POWER TRAIN, SEATS, WHEELS
I am having trouble with these things now. The powertrain especially I have not had accident yet but it keeps going dead on me in the middle of driving down road. Causing me to have to put in neutral and restart. At this time the steering goes out. This needs to be repaired before an accident does happen. The drivers seat does not move forward or backwards. The tire pressure warning does not warn until it is at 20 psi.

ELECTRICAL SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Over the past couple years I have become worried to even drive this vehicle. Well Taken care of and maintenance completed regularly. This vehicle has been in the shop 7 times in the past couple years but no one can tell me exactly what is going on. Only 1 place has told me that I need extensive electrical work but couldn't tell me what exactly the problem was. Issue #1: When coming to a stop, and/or idle, the engine seems to give up and vehicle shuts off. Issue #2: When started Engine sounds like a.high pitch raddle. Issue #3: Occasionally, while driving on the interstate going around 60 - 65 mph the electrical inside the vehicle will flash and everything shuts off and the emergency brake is applied automatically. This has become dangerous - if I wasn't wearing a seatbelt I could have been thrown through the windshield. Issue #4: Replace Fuel Cap Sensor comes on even though it's been replaced. Issue #5: Engine Power Reduced notification comes on even though it had a new battery and alternator. Issue #6: Occasionally Speakers sound blown and you can hear a buzzing as you accelerate. Issue #7: Stabili Track, ABS, and TPMS Sensors all come on at once and go away at once atleast 4 times a week. Issue #7: Rear Cam doesn't always work, sometime either black or static looking. Issue #8: Sometimes key sticks in ignitiin and will not turn on unless being jumped by another vehicle. Issue #9: Often upon starting the whole dash goes black and will stay that way for several hours then comes back on. I've checked all fuses and multiple mechanics can't figure it out. As time goes by without repair I'm scared to even drive this vehicle. Why can't someone figure this out!!

VISIBILITY/WIPER
While driving in a rainstorm, the wipers stopped working. This caused my visibility to suddenly become extremely compromised. A tractor trailer was in front of me and spraying water from the tires due to heavy rain as well. I had to pull over, under an over pass, and wait out the rain. This is extremely dangerous in of itself to be on the side of a major highway. I have since investigated and found the ball joint connection to the wiper arm corroded and broke off. The wiper motor still runs. This is identical to the 2013 GMC terrain issue.

While driving in the rain, my windshield wipers just stopped working while in an upright position on the windshield. Not only could I not see due to the rain, the wipers were actually blocking my view as well. They now will not turn on at all.

VISIBILITY/WIPER
My wife was driving home at night from school when a thunder shower popped up. She tried her windshield wipers and they did not work. It was a very serious situation as she was driving on rural roads with no place to pull over. It sounds like the wipers become disconnected from the motor somehow as you can hear it running. I have seen on another site that this seems to be a common problem with these vehicles and should be recalled as it happens suddenly and could cause injury.
