That same vehicle is believed to have travelled west on the M4 motorway and Great Western Highway towards the Blue Mountains.
Despite extensive inquiries, Jessica has not been seen or heard from since.
Anyone with information which may assist in locating Jessica is urged to call Crime Stoppers on 1800 333 000.

The NSW homicide squad is leading a search of the Hampton State Forest in the state's central-west in a bid to find missing Sydney woman Jessica Zrinski.
Homicide Squad Commander Detective Superintendent Danny Doherty said information from the investigation had led police to the forest near Jenolan.
"From the information and evidence we've gleaned so far from the investigation, and that's come to hand, there was sufficient information to commence a search," Superintendent Doherty said.
"We've committed to a large number of resources with the view of finding some trace of Jessica.
"We're hoping through the search we may be able to find some answers for the family."
Ms Zrinski disappeared on November 28, 2022.
She was last seen at a hotel carpark in the Sydney suburb of Greenfield Park. CCTV footage showed the 30-year-old getting into a blue Holden Commodore station wagon about 10 minutes later.
That same vehicle is believed to have travelled west on the M4 Motorway and Great Western Highway towards the Blue Mountains.
Police were alerted to Ms Zrinski's disappearance on December 3 when family members could not locate or contact her.
Superintendent Doherty said her disappearance was being treated as suspicious and the homicide squad was leading the search effort.
Police, PolAir and the dog squad, along with State Emergency Service and Rural Fire Service volunteers, were all assisting with the large-scale search effort.
"It's been six months since she's been seen alive and she was very close to her family," Superintendent Doherty said.
"She's missed many important dates.
"We're treating this as a suspicious disappearance and we have concerns for her welfare."
The search is expected to continue until Sunday.
Anyone with information should contact police or crime stoppers on 1800 333 000.
The family of Sydney woman Jessica Zrinski are in a tense wait for answers as police spend a second day scouring a forest near the Jenolan Caves for the missing 30-year-old.
On Saturday afternoon Jessica’s father, Dark Zrinski, told this masthead he had given up hope of seeing his daughter alive again as search crews raced to use the last remaining hours of daylight to continue their search through the Hampton State Forest in the state’s Central Tablelands.
“It would be so emotionally satisfying to find my daughter remains,” he said. “I want so much to give Jessy a proper burial.”
Search crews were briefed at 8am at a picnic area and campsite known as the Millionth Acre and it is understood the search is concentrated in and around that area.
“As a single father it’s so heartbreaking for myself and for my family,” Zrinski said.
“Jessica was so full of life and it was such a joy to see her smile always.
“It’s the waiting and not knowing what happened to my beautiful daughter Jessica.”
Saturday’s search includes officers from PolAir, the dog
unit, the rescue and bomb disposal unit, as well as
volunteers from the State Emergency Service and NSW
Rural Fire Service.
“It’s so overwhelming to see how many people who took time out with their families to be there for me and my family,” Zrinski said.
Homicide squad detectives have taken carriage of the investigation into Jessica’s suspicious disappearance, after she accepted a lift from a stranger in the car park of a pub at Greenfield Park in Sydney’s south-west just after 10pm on November 28 last year.
Jessica entered the driver’s blue Holden Commodore, which was later seen travelling west along the M4 motorway.
Police have established that Jessica was alive and still with the vehicle in the Blue Mountains region in mid-morning on November 29.
In January, detectives seized the vehicle for forensic examination and located the driver, but he did not assist in identifying Jessica’s whereabouts.
The search began on Friday and is expected to continue into Sunday.
