Safety regulators in the U.S. have opened a probe into 2014 Jeep Grand Cherokees after receiving complaints regarding automatic braking issues.
The National Highway Traffic Safety Administration said in its probe notice on Friday that they've received nine total reports of unexpected braking incidents involving the newer Jeeps with cruise control.
The probe affects approximately 20,000 SUVs in the U.S. though a recall has not been called for yet, according to a report by The Associated Press.
"All nine reports alleged unexpected braking incidents preceded by collision imminent brake warnings and resulting in sudden reduction in vehicle speed in traffic," NHTSA said in its report.
The safety group added that at least two of the complaints were over autonomous braking incidents with no other cars or objects on the road that resulted "in rapid increase in brake force and anti-lock braking system (ABS) activations."
A number of the complaints allege that the brakes came on suddenly and almost caused a rear-end collision. A few others claim the issues have happened "multiple times" already even when no other vehicles are around, according to the NHTSA.
"I can be the only vehicle on the road and this will occur. Has been happening intermittently each and every day the vehicle is driven," one complaint reads. "Sudden unexpected stopping and unsafe performance of the vehicle putting the vehicle occupants at grave risk."
Grand Cherokee maker, Fiat Chrysler Automobiles, has already commented about the probe, saying that the vehicles meet "all federal safety standards and it's cooperating in the investigation," the AP report reads.
Luckily no crashes, injuries or fatalities have been linked to the issue yet. Anyone experiencing this issue should reach out to their local dealer for help or call Jeep's helpline at 1-877-426-5337.
