On 4/25/18 was traveling a couple of hours out of town for a meeting. While accelerating (up an incline) from a hwy work zone of 50 mph, I temporarily lost: All dial readings, power steering and engine sounded stuck in a lower gear. A few seconds later, regained everything, check engine light came on and on star pinged transmission error/ take in for service within 1 day. Dealership received U0073 code and identified 2 leaks from air conditioner. They suspected the leaks were affecting the sensors. On 5/5/18, while driving 40 mph, just 1 mile from leaving home - the same thing happened as above + traction control light came on temporarily with power steering light. Upon pulling off the road, turning the car off, sitting a minute and restarting, everything came back and only the check engine light lit. The dealership (who have fabulous customer service) identified a different set of codes and ended up replacing "the brains" of the electrical system. On 5/9/18, driving 35 mph down a slight decline- again lost all dial gauges, power steering, traction control light came on and transmission seemed to be stuck in low gear. This condition continued for a number of minutes. I pulled into a parking lot on a hill (no fun to coax the car up), turned the car off, turned it on, and still power steering, transmission and gauges aren't working right. Since home was 1 mile away, I headed that direction and after 1/2 mile everything resolved + check engine light back on. The drive that night to the dealership was special. 50% of the time the power steering was on and off along with inability to accelerate, especially up hill. This time 5 different electrical codes were identified. So far, dealership has recharged the battery and are driving the heck out of it to see if more codes pop up. They do not yet feel it's fixed. Was there a bad batch of 2015 Encores?

I was driving on a highway at 65mph. On a straight portion of the road the engine light came on, the engine revved up to over 4000 RPM, the power steering locked up, and many other lights came on on the dashboard display. This was a very dangerous situation trying to control the car. I was forced to slow down and when I reached 40mph the power steering came back on. The engine was still running over 4000 RPM. Most of the dashboard display lights went off except for the check engine light. Had to drive under 40 mph until I got home. While this was happening my onstar sent me a notification that there was something wrong with my transmission. The car was then towed to the GM dealer. At the GM dealer they could find nothing wrong.there were no error codes in the cars computer.

The contact owns a 2015 Buick Encore. While driving 45 mph, the steering wheel seized and the power steering warning indicator illuminated. The vehicle was towed to carl black Chevrolet Buick GMC (1110 roberts blvd, kennesaw, ga 30144 (770) 424-2200), but the failure could not be duplicated due to a dead battery. While the vehicle was being towed, the keys were left in the ignition and caused the battery to die. The dealer stated that the vehicle could have automatically reset itself as a result of the dead battery that needed to be recharged. The vehicle was not repaired. The manufacturer was notified of the failure and confirmed that the VIN was not included in NHTSA campaign number: 15V146000 (steering). The failure mileage was approximately 24,000.

Car slowed to approx. 40 mph, with the RPM's racing to approx. 4500/6000. Engine was still running and not over heating or any other lights except check engine and power steering light. Stopped car on shoulder to take inventory of situation, car running and idile RPM's seemed normal chk. Engine and power steering light still on, proceeded to drive again. No leaks or overheating. All gauges came back up/ on. Proceed to drive... car had no acceleration, very little, like the car was still in a higher gear. Speed up very slowly until it reached approx 55-60 mph. But the RPM's were at 5500/6000, felt like the tranny needed to shift but wouldn't. slowed down to approx. 35-40.. to get RPM's in line or more in line. Drove home last hour on side roads and frontage roads with flashers on. Can't drive that slow on a freeway. All of car functional were normals, ac, radio, windows, lights. Just the power steering and check engine light stayed on with no acceleration power or power steering....called dealer Monday morning for a tow into the shop.

Driving about 45-50 mph and the car suddenly turned off. The steering wheel became stiff and all the electrical power turned off, and the dash board screen was black. I then turn the ignition key off and restarted the car in the middle of the main driving road.

While braking to stop for a traffic light on a busy 45 mph speed limit road, the engine stopped running. I shifted into park to restart it. Entire electrical system was dead except power seats and door locks. Engine would not start and no other electrical related equipment worked including engine, gear shift, instrument panel, radio, lights, turn signals, and emergency lights. Two safety issues because the car could have been rear ended: 1). could not shift out of park to push car off the road. None of the 4 ladies in the car could get it out of park. Fortunately, when my husband arrived he could not get it out of park either. Two macho police officers gave it a try, but failed also. After some effort, the tow truck driver was able to put it into neutral by using the shift lock maual release. None of us ever heard of it 2). Emergency flasihing lights did not work GMC dealer told us a weld on the battery failed causing battery wire to short. I don't understand why some power worked, but there should be a backup source for emergency flashing lights.
