“While accelerating to highway speeds, the vehicle suddenly experienced a significant and continuous loss of power. Even with the accelerator fully pressed, the vehicle would not increase speed beyond roughly 50 mph. Based on the behavior and previous service history, the issue appears to be related to the engine, fuel delivery system, or overall powertrain. The incident created a serious safety concern for both the occupants and surrounding traffic. The vehicle could not properly accelerate, merge, or respond to normal highway conditions. Hazard lights had to be activated, and the vehicle remained in the slow lane for an extended period to avoid faster-moving traffic. The issue was consistent and repeatable throughout the drive. Multiple attempts to accelerate resulted in the same lack of response, and the loss of power persisted for the duration of the trip. The vehicle has not yet been inspected following this occurrence because when turned off and turned back on, the issue goes away and happens sporadically. It is also worth noting that the vehicle previously underwent a manufacturer-covered repair involving the high-pressure fuel pump, for which a warranty…”
“I noticed my driver head light starting to get condensation after doing further research i found it’s a common manufacturer defect especially for the g70s. I took a further look by removing my front bumper & noticed 3 cracks starting from each screw on the front of the headlight mounting. after doing more research i found out it’s a common manufacture problem with over torquing the screws & after inspection that’s exactly why my headlight lense is cracking from bottom to top, as it’s too much force where the screws are & with hot & cold temperatures plastics & such move creating them to break. my safety is put at risk due to the corrosion building in the headlight causing my blinker to malfunction & my daytime lights to stop working. i’ve got pulled over for my daytime lights not being on as it looked like a headlight was out. it also is causing my car to short sometimes itll turn of driver monitoring & lane departure all of it, i will have lights on the dash for a few seconds or minutes & my car will act strange even when going in reverse the backup camera pulls too much electricity sometimes causing it all to go black & car will die randomly then turn back on…”
“Headlights are defective and the seals give out and allow condensation to build on the inside making the light not function properly and then burn out as the condensation accumulates. Lane keep assist cannot function properly if traffic merges in, has trouble determining the lines and want to over correct as it completes the merge. Also drifts during the merge. Scary.”
