2.8% of complaints about the 2017 GMC Terrain came in the first year, which is unremarkable for a 2017 vehicle — around the middle of the 203 model-years on record. The median complaint arrives at 6.3 yr in service. The most-reported system is engine (77 complaints), typically at 7.3 yr or about 80,000 miles.
General Motors, LLC (GM) is recalling certain 2010-2017 GMC Terrain vehicles. A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
OUR NEW TERRAIN HAS "VEHICLE IN FRONT" VISUAL WARNING SYSTEMS. WE WERE FOLLOWING A TANKER TYPE SEMI ON THE INTERSTATE AND PULLED ALL THE WAY UP BEHIND THE TANKER SEMI (WITHIN 25 FT) AND THE VEHICLE IN FRONT LIGHT NEVER CAME ON. WE TESTED THIS ON ALL TYPES OF CARS AND TRUCKS AS WELL AS STANDARD BOX TYPE SEMI AND IT WORKED PERFECTLY. I HAVE PICTURES OF THE REAR END OF THE TANKER SEMI IN WHICH IT DID NOT DETECT AT ALL.
SIDE BLIND SPOT ALERT COMES ON AND OFF WHEN RAINING OR SNOWING WITH NOTHING THERE, THEY SHOULD TELL YOU THIS WILL HAPPEN BEFORE YOU PAY EXTRA FOR THIS PACKAGE, HOW DO YOU KNOW IF IT WORKS OR NOT WHEN DRIVING DOWN HIGHWAY
BLIND SIDE ALERT ACTIVATES WHEN IT IS RAINING AND THERE ARE NO CARS NEARBY. THIS ONLY OCCURS WHEN RAINING. NO CODES ARE THROWN SO DEALER SERVICE WON'T TROUBLESHOOT. THIS CAN ONLY BE REPRODUCED ON A HIGHWAY OR PARKWAY, WHEN IT IS RAINING AND NO OTHER CARS ARE NEARBY. CANNOT BE REPRODUCED ON REGULAR STREETS WITH OTHER CARS AROUND. I'VE HAD MY CAR IN TO THE DEALER SERVICE 3 TIMES, ALL WITH THE SAME RESULTS. NO CODES IN THE COMPUTER AND CANNOT REPRODUCE. THE SERVICE DEPARTMENT ONLY TESTS ON THE LOCAL STREETS. THERE ARE OTHER CARS AROUND, SO HOW CAN THIS BE AN ACCURATE TEST???
AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.
