Brake Antilock Wheel Speed Sensor Problems of Dodge Challenger

The brake antilock wheel speed sensors on the front wheels locked into skid mode and my car would not go over 4 miles an hour. When I left the dealership and pulled out on to the main road I could not go over 4 miles an hour. I was almost rear ended since the speed limit on the road was 40 mph. I was told the sensors were bad and needed to be replaced. When I limped the car back into the dealership, they told me that they could not get the car out of that mode until they replaced the sensors. The car only has 7200 miles on it.

The following occurred during normal driving conditions over a period of two weeks with warning lights vehicle displayed abs and traction control warning lights simultaneously. Then suddenly the car, an automatic transmission, would not shift out of first gear. Local dealership service dept stated the computer sensed brake malfunction and caused a "limp mode" causing the transmission not to shift. This is so the car would not reach normal speeds because the brakes were malfunctioning. Dealer shop reports speed sensors on brakes failed due to excessive heat. This is odd because invoice reports the rear sensors failed when normally the majority of braking, producing heat, is from the front brakes. Resulting repairs included replacing both front rotors and left front caliper and both rear speed sensors, and flushing fluid all due to excessive heat. This is a contradiction that they report the rear speed sensors failed. Perhaps a clerical error. All is documented on ed volyes Chrysler Dodge dealership service invoice # 883127, in marietta, GA. Searching the internet shows numerous brake failure stories due to speed sensors in this make and model car. Some are easily "near death experiences". I can only hope they filed NHTSA reports as well. Final systems failure occurred on may 27th. We've had lengthy experience with much older antilock cars of other makes with no hint of failure like this ! I fail to see why a critical failure such as this would be acceptable on any safety standards.

While operating normally, approximately 35-65 mph both highway and county roads, on the way to work, the service abs & stability control system warning lights came in, steering and braking were affected. Brake system started pulsing and steering system vibrated. 20 seconds later, went away. On the way home, it repeated this 4x within 35 miles of travel. Went to dealership the next day for issue. They claimed it to be a faulty wheel speed sensor. Replaced sensor. 49,575 miles at time of service. A $42 part ended up costing $310 to get fixed. This is a dangerous thing to happen to fairly new car. Car has never seen snow or salt. Garage kept in winter months. This affected the braking and steering systems. 2 of the most important systems on a vehicle in order to operate safely on the road. I am the 3rd person I know of who's had this same issue with the same year Dodge. This should be a factory recall on all the sensors for these systems to be replaced.

4 July 2017, while driving at highway speeds, vehicle fault indicators showing problem with stability control system, abs system, and disabled cruise control. Faults cleared approximately 30 seconds later. 5 July 2017, vehicle again displayed same faults, however, faults remained latched (did not self clear). I contacted local dealership for service, fault was diagnosed on 6 July 2017 as a failed right front wheel speed sensor. Service department placed needed part on order, returned keys to me and arrangements were made to bring vehicle back to dealership for repair on 7 July 2017. While continuing on to place of work, faults returned, then cleared. At the end of day, 6 July, was approaching a stop sign at normal approach speeds and applied brakes. Front brakes initially operated as normal, then within a second or so, lost brake pressure. . . I felt the abs system release the brakes, causing me to exert enormous pressure on the brake pedal within a few feet of the stop sign to get the vehicle stopped from only a few mph. Oncoming traffic was 55 mph. After the vehicle stopped (barely). . Then the same faults appeared. From my point of view, the intermittent wheel speed sensor caused the front abs system to activate on a dry road, essentially disabling my front brakes while in the process of braking. This is not an expected failure mode. I understand onboard diagnostics indicating the problems above, however, it appears that if this problem takes place while braking, brake performance is compromised. This is now the second wheel speed sensor to be replaced in the last 6 months or so. From my perspective, that means that this is a high failure rate item (last one was on the right rear wheel), and if it happens while braking. . . I essentially lose braking at the precise moment brakes are needed. I consider this a design issue. Redundant sensors recommended for abs.

The contact owns a 2011 Dodge Challenger. While operating the vehicle, the instrument panel warning and sensor lights suddenly illuminated along with the abs sensor light. The vehicle was taken to the dealer where it was diagnosed that the wheel speed and tire sensors were faulty and would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 43,000.
