Electrical system · 2018-04-09 · NHTSA complaint #11084068
I was only able to stop the vehicle by manually operating the parking brake. Had I not had the presence of mind to utilize the parking brake I would have collided with the traffic stopped in front of me. Upon inspection I noticed a large mount of brake fluid under the driver's side front wheel.
Service brakes · 2016-12-10 · NHTSA complaint #10934362
I was able to veer back into my lane and slow down to get out of the roadway, but the brakes did not work except once the car was moving at minimal speed. When I got out of the car, I examined the rotors to see if they were hot; they were not.
Service brakes · 2016-12-05 · NHTSA complaint #10930005
Corrosion of hard brake line at driver / left side rear, partly hidden from view. Not seen during inspections. Condition discovered following surface roadway incident. Vehicle was stationary, in drive, pointed downhill at stoplight. Brake pedal slowly started going down.
Service brakes · 2015-10-01 · NHTSA complaint #10779106
Tried to open rear lift gate and window. Could not access either. There is no emergency access, no key or manual entry. Took it to mechanic, checked all fuses, no failures there. Apparently, there is a separate motor for the lift gate and window.
Structure · 2014-05-24 · NHTSA complaint #10593893
I can't open it from the inside or outside, and the window won't open either. This is a safety hazard, and I am finding many other people online are having the same issue as I am.
Structure · 2013-10-26 · NHTSA complaint #10549607
The rear liftgate will not unlock with key fob or interior door locks from the driver side or the passenger side doors. There is no way to manually unlock or open the liftgate from inside or outside the vehicle.
Structure · 2013-02-17 · NHTSA complaint #10498414
We then were going to see the racetrack ,after going about 3 miles the "engine coolant overheating" light came on. I immediately pulled into a napa store and checked the coolant level which was normal.
