I recently rear ended a car and the front of the vechical was damaged. The air bag censor was destroyed, however the airbags did not come out. This was on a 2018 Ford c-max. Many people pointed out this malfunction and how my life was put at risk.

The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was unknown.

Sep 14, 2022Fuel system

Recently, there has been a whiff of gasoline around my garage but there is more than one vehicle in there so I didn't figure out what the culprit was for a while. After completely filling up my car 9/3/2022, I parked it in the attached garage and in minutes my whole house smelled like gasoline. So I immediately parked it outside and ventilated the house. I took the car to a local shop and they said yes there's a gas odor but they didn't want to touch the repair because it's a hybrid. So all this time later on 9/14/2022, the Ford dealership saw the car and stated that it requires immediate repair and park it outside while we wait for parts. My C-Max has always gotten regular normal maintenance like oil changes and brakes, it got new tires recently. There was one major repair Ford did when the car was assembled incorrectly at the back hatch hinge seal so water was pouring into the circuit board and the battery compartment which screwed up the electronics, and the touchscreen needed replaced, but that was over a year ago and the car has been ok since. It has never ever been wrecked beyond little dings like shopping carts. It makes absolutely zero sense that the car would require this major repair at 82830 miles, and it's going to cost me $2400 which blows my mind. And it's dangerous! Now it has the doom vibe of a Pinto. I am extremely concerned for other C-max owners.

Aug 2, 2021Seat belts

The contact owns a 2018 Ford C-MAX. The contact stated that the seat belt failed. The contact stated that while the driver’s side rear seat belt was fastened to the car seat, the seat belt tightened up independently on her grandchild’s chest. The contact’s grandchild was unable to breathe properly. The contact was unable to unfasten the seat from the clip. The contact had to cut the seat belt to be able to release the seat belt from her grandchild’s chest. The vehicle was taken to the dealer to be inspected. The contact was informed that the seat belt operated as designed. The seat belt was not repaired or replaced. The manufacturer was not notified of the failure. The failure mileage was 14,000.

ELECTRICAL GREMLINS SINCE THE FIRST DAY. TOUCHSCREEN WENT ON AND OFF, PHONE DIDN'T CHARGE, DOOR HANDLES DON'T WORK, GARAGE DOOR OPENER FORGOT SETTINGS, PRESETS ON DASH WOULD BLINK OUT OF MEMORY. ULTIMATELY THE CAR DIDN'T EVEN START. BUT FOR ALL OF THESE PROBLEMS, SOMETIMES THEY WOULD WORK, SOMETIMES THEY WOULDN'T. ULTIMATELY GOT THE YELLOW WRENCH OF DEATH. BROUGHT IT IN REPEATEDLY AND THEY COULD NEVER REPRODUCE THE PROBLEM, UNTIL THE DAY IT WOULDN'T START AT ALL AND THE WRENCH WAS ON THE DASH. FINALLY DIAGNOSED OPEN SEAMS ON THE BACK HINGES TO THE HATCH. SEAMSEAL WAS MISSING ON BOTH HINGES. WATER WAS COMING INTO THE JUNCTION BOX WHICH WAS SOAKED. THE BATTERY WAS SITTING IN A POOL OF WATER. THESE PROBLEMS HAPPENED WHETHER IT WAS PARKED OR RUNNING.

Feb 11, 2020Visibility & wipers

THE RIGHT-HAND OUTSIDE REARVIEW MIRROR CONTAINS A SMALL INSET MIRROR INTENDED TO PROVIDE A DIFFERENT ANGLE OF VIEW SO AS TO GIVE THE DRIVER VISIBILITY OF VEHICLES ALONGSIDE OR IN THE "BLIND SPOT." IT IS SUPPOSED TO BE MOUNTED AT AN ANGLE RELATIVE TO THE PLANE OF THE MAIN MIRROR SIMILAR TO THE DRIVER SIDE MIRROR, BUT ON MY CAR IT IS MOUNTED IN THE SAME PLANE AS THE MAIN MIRROR SO THE VIEWS ARE IDENTICAL. FORD DEALER'S SERVICE MANAGER SAYS IT'S CORRECT, BUT EVERY OTHER FORD VEHICLE I HAVE SEEN HAS AN BLIND SIDE MIRROR THAT IS ANGLED. FORD'S CUSTOMER SERVICE CONSULTANTS REFUSE TO DISPUTE THE LOCAL DEALER'S OPINION. I BELIEVE THIS MIRROR WAS MANUFACTURED AND INSTALLED IN ERROR. FORD'S OWNER MANUALS FOR VARIOUS MODELS ALL DESCRIBE THE BLIND SPOT MIRRORS IDENTICALLY, BUT MY MIRROR DOES NOT CONFORM TO THOSE DESCRPTIONS. MORE CRITICALLY, IT DOESN'T PERFORM ITS INTENDED FUNCTION.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Ford Cmax Hev verdict →
