2017 Mazda CX-5: jerking or lurching

Filed Oct 12, 2026 · Acceleration, Engine · CO

My 2017 Mazda CX-5 has experienced a recurring condition more than six times involving sudden jerking, rapid deceleration, and loss of normal accelerator response during extended highway driving, often while cruise control is engaged. On multiple occasions the engine has also shut down. On 09/11/2026, while traveling south on I-35 at approximately 80 mph with cruise control engaged, the vehicle suddenly began jerking violently and rapidly losing speed. Normal accelerator response was lost and a vehicle behind me nearly struck my vehicle. I was able to reach the shoulder just before the engine shut down. The vehicle would not restart and required towing. There was little or no meaningful warning before the loss of power. The vehicle was inspected by a Mazda dealer. I specifically reported the recurring highway jerking, deceleration, loss of throttle response, and shutdown concern. An aftermarket OBD-II device was removed after the dealer identified parasitic battery draw. The dealer subsequently stated in writing that the battery and alternator were healthy and that the vehicle was “operating as intended.” On 10/09/2026, with that device no longer installed, the same symptoms occurred again during highway travel and the vehicle again became disabled and required towing. The Mazda dealer has now verified the drivability concern and reported a Fuel Rail Pressure Sensor “A” Circuit Low fault and low fuel pressure. The dealer is recommending replacement of the high-pressure fuel pump as an initial repair, followed by further testing of the in-tank fuel pump. The vehicle is currently available for inspection at the Mazda dealer. the federal safety agency’s VIN lookup currently shows 0 unrepaired recalls. I am reporting this because sudden loss of acceleration and power at highway speed creates a serious collision and roadside safety risk.

The brake pads on this vehicle wear out prematurely, despite not using them aggressively. All four brake pads on the SUV wore out in less than the first 16,000 miles (first 3 years) and had to be replaced. The braking has also aways been “soft” and the car takes longer to come to a full-stop in the event urgent braking has to be done in traffic. The rotors have corroded prematurely too, despite keeping the car very clean and dry as a matter of habit. The dealer dismissed this issue stating the brakes were fine, as if this was the first car I was driving. I do not engage in hard stops, or perform sudden, jerky, brake applications and yet the brake pads wore out to almost nothing. All the other cars that I’ve owned historically had their brake pads last for 6-8 years of normal driving while this car wore them down in just 3 years. Premature brake pad wear can be a huge safety issue since an unsuspecting driver may not be aware of it and can result in an accident on the road from the vehicle not being able to come to a full stop in time.
