Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The contact's boyfriend owns a 2015 Ram Promaster 2500. The contact stated that while her boyfriend was driving at an undisclosed speed, the check engine warning light illuminated. The driver continued driving, and the vehicle entered LIMP Mode and failed to accelerate above 5 MPH. The vehicle was taken to a dealer where it was serviced under an unknown recall; however, soon after the vehicle was repaired, the failure returned. The vehicle was taken back to the dealer and serviced a second time under the same recall. Recently, the contact stated the failure returned, and the vehicle was taken back to the dealer. The vehicle remained with the dealer for several months before the contact was informed that the vehicle could not be serviced. The contact was advised to retrieve the vehicle. The manufacturer was notified of the failure, and the contact was provided with the same information as the dealer. The vehicle was not repaired. The failure mileage was approximately 150,000.

While driving on the freeway my engine started slowing down and a message came on the dash saying "Transmission Service". I was fortunate enough to make it to the right shoulder from the first lane and the engine stopped. The readout on the dash said I was in neutral but I was in park. The car wouldn't start. After cooling down I could start and drive but the same issue would happen intermittently. I took it to AAMCO and they told me that there was a recall for the range sensor and wiring harness (S55/NHTSA 16V-529). When I got to the dealer he said that recall didn't pertain to my vehicle and I would have to pay for the service. Since the issue does cover vehicles of my make, model and year I want to know why isn't it covered? It's the same issue as the ones covered. I'm lucky that I wasn't involved in an accident because of this.

The contact owns a 2015 Ram ProMaster 2500. The contact stated that the same day that the vehicle was purchased, the check engine warning light illuminated. The contact stated that after shifting to park(P) and the parking brake was engaged, the vehicle rolled backwards. The vehicle was taken to the dealer, who diagnosed the vehicle with an unknown sensor failure. The sensor and the brakes were repaired. The contact retrieved the vehicle, and the check engine warning light was illuminated. When the gear lever was shifted to park(P) and the parking brake was engaged, the vehicle rolled backwards. The dealer was contacted, and the dealer at first refused to take the vehicle. After several months, the dealer took the vehicle, and it was diagnosed and determined that the fuel injectors, brakes, fuel tank, and an unknown sensor needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the failure persisted. The vehicle was parked at the residence and had not been driven since. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

Several incidents when accelerating, the engine goes into a limp mode, followed by indicator lights coming on P0401, P0299, P226C. The vehicle will not accelerate and travels at a max speed of about 5mph. This has happened in traffic every time and has put me and my family, as well as other vehicles, at extreme risk of being in an accident, not being able to accelerate out of the way of oncoming traffic. After several cycles of turning the vehicle off and on, it returns to normal function. The vehicle has been inspected at a Dodge Service station. They determined that the Turbo diesel system is malfunctioning and needs repair. My vehicle is available for inspection upon request.

WATER ENTERS THE ENGINE COMPARTMENT. THE COWLING BELOW THE WINDSHIELD IS A 2-PIECE UNIT WITH A "JOINT" IN THE MIDDLE, WHERE WATER ENTERS AND FORMS ON TOP OF THE ENGINE AND ELECTRICAL COMPONENTS, WHICH COULD CAUSE THE ENGINE TO STOP. THERE IS ALSO A LEAK ON THE DRIVER'S SIDE AND FLOWS ON TOP OF THE FUSE BOX AND ELECTRICS. THERE IS ALSO A LEAK ON THE PASSENGER SIDE WHERE WATER ENTERS FROM THE HOOD VENT AND GOES ONTO THE AIR INTAKE AND THEN CAN GO INTO THE ENGINE. MANY OWNERS HAVE CONTACTED THEIR DEALERS AND NOTHING HAS BEEN DONE TO CORRECT THIS PROBLEM. I HAVE BEEN TRYING SINCE 2015. SEVERAL OWNERS HAVE HAD THEIR ALTERNATORS QUIT BECAUSE OF WATER AND THE ENGINE HAS DIED WHILE DRIVING. FOR FURTHER INFORMATION GO TO WWW.PROMASTERFORUM.COM UNDER GENERAL DISCUSSION AND DO A SEARCH FOR WATER IN ENGINE COMPARTMENT. GOOGLE ALSO PROVIDES INFORMATION. THIS IS HAPPENING IN EUROPE A WELL AND THEY HAVE SOLVED IT WITH A DRIP PAN, AND/OR OTHER MEANS OF SEALING THE AREA. I ALSO HAVE A VIDEO OF THE LEAKING WHEN IT RAINS, BUT CAN'T UPLOAD IT.

THERE IS A DEFECT IN THE BRAKING CONTROL MODULE THAT DOES NOT ALLOW A PROPER SIGNAL TO A TRAILER FROM THE VAN. THE DEFECT PREVENTS BOTH BRAKE AND TURN SIGNALING IN ANY MANNER FROM THE TRAILER AT ANY SPEED OR AT A STAND STILL. THIS DEFECT SEEMS TO HAVE BEEN PRESENT FOR 2 YEARS, NO NOTIFICATION HAS BEEN GIVEN TO ME BY THE MANUFACTURER. I FOUND THE ISSUE BECAUSE I BOUGHT A NEW TRAVEL TRAILER. WHEN I ASKED THE DEALER ABOUT THE ISSUE THEY STATED THAT CHRYSLER CORPORATION HAS A RESTRICTION ON ORDERING THE PART TO FIX THE ISSUE. APPARENTLY ONLY ONE CUSTOMER CAN BE SERVICED AT A TIME. THEY STATED THAT EACH PERSON TAKES AROUND 2 WEEKS TO SERVICE. I AM APPARENTLY 6TH IN LINE FOR THE PART. THIS MEANS I HAVE A 2 1/2 MONTH WAIT TIME BEFORE I CAN TOW A TRAILER. THE LENGTHY FIX WAIT TIME LEAVES ONE TO BELIEVE THAT UNSCRUPULOUS OWNERS ARE TOWING WITHOUT SIGNALING EQUIPMENT AND THUS ENDANGERING LIVES. APPARENTLY CHRYSLER IS IN NO HURRY TO SOLVE THE ISSUE WHICH IT HAS KNOWN ABOUT FOR WHAT I AM GUESSING IS A 2 YEAR PERIOD. THE CHRYSLER GROUP IS WILLFULLY COVERING UP DANGEROUS DEFECTS. WHEN DISCOVERED, PRESUMABLY AFTER ONE HAS TOWED A TRAILER SOME DISTANCE, THEY AGAIN CONTINUE TO DENY THE SEVERITY OF THE ISSUE BY SLOWLY REPAIRING VEHICLES THAT ARE AFFECTED BY THE DEFECT. SEE FOR YOURSELF, CALL A DEALER AND ASK THEM ABOUT THIS ISSUE. IT IS RECALL S29 FROM WHAT I HAVE BEEN TOLD. APPARENTLY THE "S" STANDS FOR SECRET.. ASK THE FIRM EXECUTIVES WHY ONE HAS A VEHICLE WITH THIS ISSUE FOR 2 YEARS BEFORE THEY MUST FIND OUT ON THEIR OWN THEY COULD KILL SOMEONE BY TOWING A TRAILER. WITH NO OPERATIONAL BRAKE OR TURN SIGNALS.

THERE IS A SERIOUS DEFECT IN THE PARKING BRAKE WHICH CAUSES IT TO FREEZE AND LOCK UP IN COLD TEMPERATURES. THIS VEHICLE HAS AN AUTOMATIC TRANSMISSION WITH NO PARKING GEAR SO THE PARKING BRAKE IS REQUIRED TO PARK THE VEHICLE SO THAT IT DOES NOT ROLL. WHAT HAPPENS IS THAT WATER GETS INTO THE PARKING BRAKE CABLE AND FREEZES IN SUBZERO TEMPERATURES CAUSING THE PARKING BRAKE TO NOT ENGAGE, NOT RELEASE, OR ONLY RELEASE PARTIALLY SO THAT IT DRAGS. FROM THE DRIVERS PERSPECTIVE IT APPEARS NORMAL OTHER THAN HAVING LESS OR NO TENSION WHEN THE PARKING BRAKE LEVER IS APPLIED.OR RELEASED. WHEN THE CABLE IS FROZEN WHILE THE BRAKE IS DISENGAGED, THE BRAKE DOES NOT ENGAGE, SO THERE IS NO WAY TO PROPERLY PARK THE VEHICLE. WHEN FROZEN WHILE ENGAGED, THE BRAKE REMAINS ON OR ONLY PARTIALLY RELEASES WHICH CAUSES IT TO BE UNABLE TO MOVE THE VEHICLE OR THE BRAKE WILL DRAG AND OVERHEAT WHILE DRIVING. WE HAVE TWO OF THESE VEHICLES PURCHASED AT ABOUT THE SAME TIME FROM . ONE IN MINNESOTA AND THE OTHER IN TEXAS. BOTH HAVE THE SAME PROBLEM SO IT CLEARLY NOT AN ISOLATED PROBLEM. ONE COST US OVER $2000 TO FIX BECAUSE THE ENTIRE BRAKE ASSEMBLY BECAME OVERHEATED AND DESTROYED ALMOST ALL OF THE WHEEL COMPONENTS. I'VE ATTACHED THE INVOICE FOR THE REPAIRS. THIS IS VERY DANGEROUS! I HAVE NOT BROUGHT THIS UP EARLIER BECAUSE I WAS CERTAIN THAT IT WOULD BE RECALLED FOR THIS BY NOW. WE USE THESE FOR DELIVERIES AND NOW OUR MANAGER IN MINNESOTA WILL NOT OPERATE THE VAN IN THE WINTER FOR SAFETY REASONS. TODAY THE DRIVER HAS NOT BEEN ABLE TO USE THE PARKING BRAKE AT DELIVERY STOPS SO HAS TO FIND A PLACE TO PARK ON A HILL WITH THE WHEELS TOWARD THE CURB. THIS IS NOT A SAFE WAY TO PARK THE VEHICLE. THESE VEHICLES REALLY NEED TO BE RECALLED BEFORE SOMEONE IS IN A SERIOUS ACCIDENT.
