2016 Jeep Compass Transmission Problems

Your Compass has suddenly lost all engine power while driving with no warning, and recently has had trouble accelerating even though no warning lights or error codes appear. The dealership diagnosed a faulty internal transmission and quoted $7,500 for replacement, but couldn't pinpoint the exact problem without disassembling it. Since Mopar discontinued the original transmission part number due to known defects, you're concerned about whether this is a design flaw rather than normal wear on a vehicle with under 90,000 miles. A transmission replacement would likely involve removing the engine and transmission assembly, performing internal repairs or complete replacement, and reinstalling the powertrain.

Your Jeep is experiencing a serious electrical grounding problem that causes you to lose power while driving, making your headlights, interior lights, and dashboard flicker unpredictably—a safety hazard confirmed by a professional mechanic. You've also had to replace the throttle body and ignition coils multiple times within six months, and the engine is running hot without any visible coolant leaks. The power loss issue is particularly dangerous and needs to be diagnosed by checking the vehicle's grounding connections and electrical system. Fixing this will likely involve inspecting and repairing the ground wires, replacing faulty ignition coils, and diagnosing the cooling system.

Your check engine light came on while driving, and your Jeep's engine stopped responding to acceleration, then shut off completely — nearly causing an accident. You had to have the vehicle towed and abandon it on the road. This appears to be related to the electronic throttle control system.

After having your catalytic converter and oxygen sensor replaced, your vehicle started shaking and won't accelerate past 20 mph. Your mechanic's diagnostic reader isn't picking up the cause of the problem, showing only invalid data. You may need the vehicle's computer system scanned with specialized diagnostic equipment to identify what's preventing normal acceleration after these repairs.

I bought this car year and half ago and I been doing a lot of repairs in it and now the engine light came on and stated the bank 1 and bank 2 sensor camshaft and engine is stalling and car is jerking very dangerous I did allighment new control arms engine mounts I repaired a lot I put new tires I can’t drive it on the high way it starts to jerk left and right and steering is very hard to control seats are horribale and so are the seatbelts.

We were driving down the road and the car started violently shaking, the check engine light went on and the car wouldn't move. The car needed to be pushed to the gas station and we almost got hit with my son in his car seat. I do believe this is a safety concern that needs to be looked into for a possible recall. The mechanic determined that the transmission needed to be rebuilt.

I’ve had plans with my Transmission. This is its third time. First two times were under 30,000 miles and still under warranty. And were replaced by the dealer . Using my warranty. There was also a motor fire. Brakes and rotors all the way around mind you all under 30,000. Transmission was put in. I am now at 101,500. And transmissions going out so it’s been parked. Sitting in my garage. The warning lamps come on, which is a parentheses with a lightning bolt in the middle(️) Last time I did the repairs through Ramona Tires and I paid for out-of-pocket using my credit This time I was told a new transmission for the car is $7000 which I don’t have

Engine cuts out while driving. Had to pull over to the side and reset by instructions from Google. Took the car to a local garage and he said it was a computer issue. This part was replaced 3-4 years ago and is failing again. A red symbol like a lightning bolt and the check engine light was on.

I have been having issues with my vehicle for the past month or so. I took it to a mechanic and they said that my Power Transfer Unit is bad and my vehicle currently doesn't have 4 wheel drive capability. My vehicle periodically stutters, slows and looses power while driving at freeway speeds. During all of my issues, not once has my check engine light or any sort of indicator has lit up letting me know I have an issue with my vehicle. I thought newer cars are supposed to know when there is an issue with the vehicle. This is completely unacceptable and now I'm looking at over $2,000 in repairs.

It will stop running while driving or making turn without warning must stop put in park and restart .The more you use more it happens. Very dangerous

Vehicle has a slow acceleration ration. I was merging onto the Freeway and pressing on the accelerator, but it does not accelerate. It takes quite sometime to pickup speed, throttle body light has just started coming on along with the check engine light. Purchased Vehicle 8/2021, no acceleration from the beginning. Check engine and Throttle Body light 2-3 weeks ago.

tHE CAR HAS STALLED AND SHUT OFF SEVERAL TIMES WHILE DRIVING ALMOST CAUSING AN ACCIDENT, WHILE DRIVING THE CAR JUST SLOWS DOWN AND WILL NOT ACCELERATE AND HAS LEFT ME STRANDED SEVERAL TIMES

The contact owns a 2016 Jeep Compass. The contact stated while her daughter was driving approximately 45 MPH, the vehicle lost motive power and stalled without warning. The vehicle was towed to an independent mechanic and was diagnosed with transmission failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 118,000.

While driving 2016 Jeep Compass vehicle jerks suddenly and feels like it is going to stall. Nothing changes on dashboard. This happens during acceleration or even just driving down the road or highway. Took it to dealership back in 2020 and the catalytic converter was replaced. The jerking stopped until now. Took it back to same dealership and the mechanic could not duplicate the problem. No codes thrown. Even though I have many witnesses hat have been in the vehicle while it occurred. Picked jeep back up and it started jerking while driving again within a 1/2 mile of driving away from the dealership. Repair not done. Feels unsafe to drive. I’m afraid it is going to stall and cause an accident. Mileage in 2020 incident 65000. Mileage this incident 76000

This morning (08.20.21) I was driving to work when about 1 mile in I was going 45mph and my car started stalling, causing it to drop to 10mph. The engine light and traction control light are consistently on. The electronic throttle control light is constantly blinking when I have the ignition on. My car has been in limp mode all day and will not go over 10mph. I almost got hit by the car behind me when it happened and almost hit someone else trying to get out of their way. I’ve been looking into it all day and I found that there was a recall “S89” on Jeep Compass 2016 made anytime between May 9, 2016 and July 15, 2016 and which came equipped with 2.0-liter or 2.4-liter 4-cylinder engines. Mine was manufactured July 15, 2016 and is a 2.0-liter.

II KEPT MY JEEP COMPASS UP TODATE WITH OLL CHANGES AND BRAKES AND TIRES. I HAVE NOW EXPERINECED A REAL BAD NOISE FROM UNDER THE ENGINE. I THOUGHT IT WAS MY BRAKES OR PULLEY. IT TURNS OUT I NEED A NEW TRANSMISSION. I HAVE A 5 SPEED. I HAVE METAL SHAVING IN MY TRANSMISSION AND MY CAR IS NOT EVEN 5 YEARS OLD. I LOVE MY CAR AND NOW IT IS GOING TO COST ME 4000+ TO GET IT FIXED. THERE ARE OTHER WARRANTYS ON THE SAME TYPE OF CARS BUT NOT MINES.

MY 2016 JEEP COMPASSES TRANSMISSION HAS FAILED AT 96000 MILES. IT HAS THE 2.0L I4 WITH THE CVT, ITS FWD. I WAS TRAVELING AT 35MPH WHEN IT FAILED.

MY CAR POWER TRAIN WENT OUT AS I ONLY HAVE THE CAR FOR 11 MONTHS AND TRANSMISSION IS NOT WORKING WELL I WAS DRIVING HOME AND THE CAR RPM WAS GOING TO 6

VEHICLE STALLS OUT AND LEAVES MOTORISTS STRANDED. ENGINE STALLS AND HAS THE POTENTIAL TO RESUME NORMAL POWER BUT HAS A SERIOUS LAG BETWEEN POWER GIVEN AND POWER ACCEPTED BY ENGINE (2-5 SECS). POSSIBILITY FOR COLLISION IS GREAT AND POSSIBILITY FOR BEING LEFT STRANDED IS GREAT. BATTERY AND NORMAL MAINTENANCE HAS BEEN PERFORMED.

CAR LOST POWER THREE TIMES IN THE LAST TWO WEEKS. TWICE WHILE DRIVING, ONE OF THOSE TIMES WAS ON THE HIGHWAY, AND THE THIRD TIME WHEN STOPPED AT A RED LIGHT

TRANSMISSION OVER HEATS AND THEN STALLS OUT WHEN IT IS WARM OUT. THE DEALERSHIPS I HAVE GONE TO SAID THERE IS NOTHING WRONG WITH THE JEEP COMPASS BECAUSE IT DOESN'T ACT UP FOR THEM. NORMALLY MAKE IT 45 MINUTES IN SUMMER BEFORE IT OVER HEATS. CANT KEEP CAR OVER 2,000 RMP IN SUMMER OR TRANSMISSION WILL OVER HEAT EVEN FASTER. HAS BEEN HAPPENING MANY TIME OVER THE LAST 2 SUMMERS. NON-DEALERSHIPS WONT LOOK AT THE CAR AND THEY SAY THAT THE DEALERSHIPS NEED TO FIX IT.

ALL OF MY LIGHTS CAME ON OUT OF NOWHERE THEN CAR WOULDN'T TURN BACK ON. AFTER DIAGNOSTICS IT WAS DETERMINED TO BE AN ELECTRICAL ISSUE WITH THE WIRING HARNESSES & ALSO WAS TOLD THAT THERE WERE ISSUES WITH MY AIRBAGS BEING ABLE TO PROPERLY DEPLOY. VEHICLE WAS ON. VEHICLE WAS IN MOTION AT ABOUT 30-40MPH. I WAS FORTUNATE ENOUGH TO MAKE IT HOME AND BE ABLE TO PARK MY CAR AND I WAS FORTUNATE I WASN'T ON A HIGHWAY OR IT COULD HAVE BEEN A VERY DANGEROUS ACCIDENT.

ABOUT 2 WEEKS AGO AFTER I PUT GAS IN THE CAR THE CHECK ENGINE LIGHT CAME ON WE CHECKED EVERYTHING CANNOT FIGURE OUT ANYTHING WRONG WITH IT THEN THE AIRBAG LIGHTS CAME ON SO WE TOOK THE BATTERY OUT PUT IT BACK IN AND RESET THE LIGHTS. THE CHECK ENGINE LIGHT CAME ON THE NEXT TIME I DROVE IT. ROUGHLY 3 OR 4 DAYS AFTER THAT IT WAS MORNING IT WAS MISTY THE ROADS WERE WET I WENT ABOUT 5 BLOCKS TOOK A RIGHT TURN WENT ANOTHER 5 BLOCKS TOOK A LEFT TURN AND ALL THE SUDDEN ANTI SKID LIGHTS CAME ON THEN THE AIRBAG LIGHT CAME ON AND THEN THE LIGHTNING BOLT LIGHT CAME ON THE CAR HAD NO POWER. SOI PULLED IT OVER AND WE HAD IT TOWED HOME I HAD A DIAGNOSTICS TEST IN IT'S C1221 I BELIEVE WAS THE CODE WE HAVE NOT DRIVE IT SINCE.

ABS 4WHEEL DRIVE AND TRACTION CONTROL LIGHT STAY ON AND WON'T COME OFF AND SINCE THEY POPPED UP I'VE BEEN HAVING ISSUE WITH MY ACCELERATION. IT'S BEEN CAUSING MY CAR TO RANDOMLY STOP ACCELERATING WHILE I WAS DRIVING ON THE HIGHWAY. MY 4WHEEL DRIVE LIGHT POPS ON A FEW MINUTES AFTER I START DRIVING BUT THE OTHER 2 LIGHTS STAY ON ALL THE TIME. *TR

I BELIEVE MY VEHICLE FITS RECALL OF THE CANAM OR POWER TRAIN SENSOR THAT NEEDS TO BE FIXED. MY ENGINE KEEPS COMING ON. THE CAR BUCKS BUT NOT ALL THE TIME. FEELS LIKE SOMETHING GOING ON WITH TRAINMISIION AND AT 87,000 THAT IMPOSSIBLE. PLEASE LOOK INTO THIS MATTER. YES BELIEVE RECALL FITS MY CAR

TL* THE CONTACT OWNS A 2016 JEEP COMPASS. WHILE THE CONTACT WAS REVERSING OUT OF THE DRIVEWAY, THE VEHICLE SHUT OFF WITHOUT WARNING. THE CONTACT ASSOCIATED THE FAILURE WITH NHTSA CAMPAIGN NUMBER: 16V907000 (ENGINE AND ENGINE COOLING). THE CONTACT WAS INFORMED THE VEHICLE HAD PREVIOUSLY BEEN REPAIRED PER THE RECALL, BUT THE FAILURE RECURRED. ALSO, WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE MADE HARD, SUDDEN JERKS WITHOUT WARNING. THE CONTACT TOOK THE VEHICLE TO BRANHAVEN JEEP CHRYSLER DODGE RAM (348 W MAIN ST, BRANFORD, CT 06405, (203) 488-6351), BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND PROVIDED CASE NUMBER: 64914088. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 30,000.

I BOUGHT A 2016 JEEP COMPASS BRAND NEW FROM THE DEALERSHIP. AFTER ONLY THREE YEARS (72,500 MILES), THE TRANSMISSION COMPLETELY FAILED WHILE I WAS DRIVING ON A MAJOR HIGHWAY. THE JEEP, WHICH IS A MANUAL 5 SPEED TRANSMISSION, WOULD NOT SHIFT INTO ANY GEARS. IT MADE HORRENDOUS GRINDING NOISES AS THE VEHICLE FAILED AND FAILED TO SHIFT INTO GEAR. PRIOR TO IT COMPLETELY DYING, IT WAS STALLING OUT ON ME AND SLIPPING OUT OF SECOND GEAR WHILE DRIVING IT. THIS IS A SAFETY CONCERN, NOT TO MENTION HOW DISAPPOINTING THAT A CAR WHICH IS ONLY THREE YEARS OLD WOULD HAVE A TRANSMISSION THAT COMPLETELY FAILED ON IT. THE JEEP WAS WELL-MAINTAINED AND GARAGE KEPT. IT WAS NEVER DRIVEN ANYWHERE EXCEPT MAIN ROADS AND HIGHWAYS.

JEEP WILL NOT START WITH KEY. THEN I HAD TO PRESS ON GAS TO GET CAR TO START, NOW IT DOESN'T START AT ALL WITH KEY. I HAVE TO USE MY AUTOMATIC STARTER TO GET MY CAR TO START THEN PUT MY KEY IN. THIS SHOULD BE RECALLED. THIS IS NOT SAFE, AND OBVIOUSLY A JEEP PROBLEM. I HAVE RESEARCHED THIS, AND SO MANY JEEP OWNERS HAVE THIS PROBLEM.

VEHICLE IS SHIFTING ERRATICALLY, IT IS A INTERMITTENT PROBLEM. WHEN FIRST BOUGHT VEHICLE DEALER TOLD ME THAT IS JUST THE WAY THAT TRANSMISSION IS. IT IS HAPPENING MORE FREQUENTLY NOW

I HAVE DRIVEN THIS VEHICLE FOR 3 YEARS WITH NO ISSUES UNTIL RECENTLY. I TAKE CARE OF IT AND MAINTENANCE IT REGULARLY. AROUND APRIL 29TH I FELT SOME STEERING ISSUES AND BROUGHT IT IN TO FIRESTONE WHO TOLD ME IT NEEDED TO BE TAKEN TO THE DEALERSHIP. AT THE DEALERSHIP, THEY REPLACED AN ABS SENSOR AND A FEW TIRE SENSORS. SINCE THEN ON MULTIPLE OCCASIONS THE VEHICLE HAS RANDOMLY AND INTERMITTENTLY STALLED WHILE DRIVING. I CAN BE DRIVING AT ANY SPEED AND THE VEHICLE WILL RANDOMLY LOSE ACCELERATION, POWER STEERING, AND BRAKES. IT HAS HAPPENED AFTER A TURN, WHILE JUST GOING STRAIGHT AT 45 MPH, WHILE IN STOP-AND-GO TRAFFIC, AND WHEN TRYING TO ACCELERATE AFTER SITTING AT A RED LIGHT. THERE IS NO RHYME OR REASON. THE IGNITION HAS TO BE TURNED OFF AND TURNED BACK ON TO RESTART THE VEHICLE. I HAVE NEARLY CAUSED A COLLISION TWICE. I BROUGHT IT TO THE DEALERSHIP ON JUNE 22ND AND THEY HAD MY CAR UNTIL JUNE 25TH. THEY REPLACED THE CRANKSHAFT POSITION CARRIAGE, AND SOME FRAYED WIRING. THE ISSUE HAPPENED 3 MORE TIMES AFTER THOSE REPAIRS. I HAD IT TOWED TO THE DEALERSHIP ON JUNE 27TH AND IT IS STILL IN THE SHOP (TODAY IS JULY 2ND). THEY ARE TELLING ME THEY CANNOT RECREATE THE PROBLEM AND WANT ME TO TAKE THE VEHICLE BACK WITHOUT DOING ANY REPAIRS. I AM NOW WORKING WITH THE GM AND CFO OF THE DEALERSHIP TO TRY AND RESOLVE THIS AND I HAVE FILED A COMPLAINT WITH CHRYSLER (CASE #59096741). I DO NOT FEEL SAFE DRIVING THE VEHICLE AND I REFUSE TO PUT MY CHILDREN IN IT. ALL SERVICE RECORDS THAT I HAVE ARE INSIDE THE VEHICLE AT THE DEALERSHIP.

VEHICLE WILL WITHOUT WARNING STALL IN THE MIDDLE OF DRIVING, IN CITY TRAFFIC, ON COUNTRY ROADS, STARTING UP A HILL AS WELL AS DRIVING ON FLAT STRAIGHT ROAD. I'VE BEEN DRIVING 55MPH, 45 MPH 25 MPH AND IT WILL STALL, THE TRACTION CONTROL LIGHT WILL COME ON. SOMETIMES THE CAR WILL NOT RESTART FOR 10+ MINUTES AFTER STALLING. EACH TIME I WAS DRIVING IN TRAFFIC, AND HAD CHILDREN IN THE VEHICLE WITH PEOPLE BEHIND ME. ENGINE JUST CUTS ALL POWER, POWER STEERING IS LOST. ALSO HAVE NOTICED A HUGE DROP IN FUEL EFFICIENCY, USED ABOUT 1/4 OF A TANK IN 30 MILES, ACCELERATION AND VEHICLE NOT SHIFTING NORMALLY. THIS IS THE 6TH TIME IN TWO WEEKS IT HAS STALLED, AND 2ND TIME TO TAKE IT INTO THE DEALERSHIP WITH THIS ISSUE. I'VE ONLY HAD ABOUT 6 MONTHS, IT WAS CPO AND HAVE DRIVEN IT ABOUT 10,000 MILES

SHIFTER WHEN PUT IN PARK SOMETIMES ROLLS

TL* THE CONTACT OWNS A 2016 JEEP COMPASS. WHILE DRIVING AND SHIFTING INTO SECOND GEAR, THE VEHICLE LOST POWER AND WOULD NOT ACCELERATE. THE CONTACT PULLED THE VEHICLE OVER TO THE SHOULDER, WAITED A FEW SECONDS, AND THE VEHICLE BEGAN ACCELERATING NORMALLY AGAIN. IN ADDITION, THE BRAKES FAILED AND THE ABS WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO HOMER SKELTON JEEP CHRYSLER (7661 US-51, MILLINGTON, TN 38053, (901) 872-0195) WHERE IT WAS DIAGNOSED THAT NEW BRAKES WITH SENSORS AND PAD LOCKS NEEDED TO BE INSTALLED. THE BRAKE FAILURE RECURRED. THE ACCELERATION FAILURE WAS NOT DIAGNOSED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS 51,117.

RIDE DOWN THE HIGHWAY GOING 70 AND ALL OF A SUDDEN THE SPEEDOMETER BEGINS TO DECREASE. I HAD ALL POWER, BUT NO ACCELERATION. I PULLED OF THE ROAD AND SHUT OFF THE ENGINE. TURNED IT BACK ON AND IT RANNED FINE. NOT MORE THAN 5 MINUTES ITS WAS BACK NO ACCELERATION. SO THANK GOD I WAS ABLE TO USE THE FORCE FROM THE HILL TO CRUISE ON HOME ON THE BACK ROADS. THE CAR IS ONLY 3 YEARS OLD AT 79,000 MILES. SO NO WARRANTY!!! IT HAS TO BE TOWED TO THE DEALERSHIP! NEW VEHICLE SHOULD NOT BE HAVING PROBLEMS LIKE THIS!!!!

AT 60,000 MILES A WHOMP, WHOMP NOICE STARTED FROM THE REAR OF THE JEEP WHILE DRIVING. MOST NOTICEABLE AT 45 TO 55 MPH ON HIGHWAY. DEALERSHIP DIAGNOSED IT AS A REAR HUB BEARING. TOTAL COST FOR REPAIR WAS $613.00 BEFORE TAX.

SOMETIMES WHEN DRIVING IT STUTTERS AND ACTS LIKE IT CAN'T CATCH UP TO THE SPEED THAT I'M GOING.

AS A MOTHER OF THREE CHILDREN, THE YOUNGEST ONLY BEING TWO YEARS OLD, I DO NOT FEEL SAFE DRIVING MY 2016 JEEP COMPASS. EVERY SINGLE TIME I DRIVE THE VEHICLE THE MOTOR RANDOMLY STALLS OUT WHILE DRIVING SEVERAL DIFFERENT TIMES. MY CAR IS VERY WELL MAINTAINED AND DRIVEN EASILY AND EVEN WITH THE GAS PEDAL UNDER LIGHT LOAD IT STALLS OUT LEAVING ME IMMOBILE OR THE VEHICLE MISFIRING AND JERKING FORWARD VIOLENTLY STRUGGLING TO DRIVE WHICH PUTS MY CHILDREN AND I IN DANGEROUS OR POTENTIALLY DEADLY SITUATIONS. THIS HAPPENS ALL THE TIME. THIS IS DUE TO A BAD CRANKSHAFT POSITION SENSOR AND OR BAD WIRING FROM THE FACTORY. WHEN I TYPE MY VIN NUMBER INTO THE NHTSA WEBSITE FOR RECALLS IT SAYS MY VEHICLE HAS NO ACTIVE RECALLS. THERE ARE SEVERAL OTHER JEEP COMPASS'S OF THE SAME YEAR AND MODEL WITH THIS EXACT ISSUE UNDER RECALL AND MY VEHICLE NEEDS TO BE INCLUDED IN THAT RECALL AS WELL. MY CAR IS ONLY TWO YEARS OLD IT SHOULD BE A RELATIVELY SAFE AND RELIABLE VEHICLE NOT SOMETHING I WORKED SO HARD TO BUY AND AN AFFRAID TO DRIVE.

WHILE AT A COMPLETE STOP, EITHER AT LIGHT OR IN TRAFFIC, MY RPM GAUGE NEEDLE WOULD DROP TO 0 RPMS, HOWEVER MY BATTERY IS STILL ACTIVE. I WILL THEN HAVE TO CYCLE KEY TO TURN VEHICLE BACK ON. THIS ALSO HAPPENED AS VEHICLE WAS MOVING/APPROACHING INTERSECTION WITH TRAFFIC LIGHT. AS I COASTED TO INTERSECTION MY RPMS AGAIN WENT TO ZERO. I THEN RELUCTANTLY WAS ABLE TO TURN STEERING WHEEL (ALTHOUGH LOST POWER STEERING) TO THE RIGHT AND CONTINUED TO COAST ONTO SHOULDER OF ROAD. PUT CAR INTO PARK, CYCLED KEY AND CAR TURNED ON BUT TOOK A SEVERAL SECONDS FOR ENGINE TO TURN OVER. TOOK VEHICLE INTO CHRYSLER DEALERSHIP 3X FOR THIS ISSUE AND THEY COULDN'T FIND PROBLEM AND COULDN'T DUPLICATE IT WHILE DRIVING IT FOR A FEW DAYS.

MY MECHANIC BELIEVE'S I HAVE A SENSOR ISSUE GOING ON WITH MY TRANSMISSION. IT SEEMS TO HAVE THE SAME ISSUES AS OTHER CERTAIN MODEL YEARS AS MINE. EVERY DRIVE I TAKE, THE TRANSMISSION SLIPS. HE HAS RULED OUT EVERYTHING ELSE, AND ONE OR TWO OF THE SENSORS ARE POINTING TO MY TRANSMISSION ISSUES. THIS PROBLEM HAS ALMOST CAUSED ME AN ACCIDENT MULTIPLE DIFFERENT TIMES. AT THIS POINT I DON'T FEEL COMFORTABLE DRIVING IT.

AFTER AN UNEVENTFUL DRIVE TO A STORE, WHEN I RESTARTED THE VEHICLE AND ATTEMPTED TO PULL OUT OF THE PARKING LOT INTO MOVING TRAFFIC, THE VEHICLE ACCELERATED VERY SLUGGISHLY, LIKE IT WAS STUCK IN TOP GEAR OR THE ENGINE WASN'T ABLE TO BE REV'ED UP. PUSHING ACCELERATOR TO FLOOR CAUSED ENGINE TO REV UP TO APPROXIMATELY 3500 RPM ONLY, AND RATE OF ACCELERATION DID NOT IMPROVE. TRIED SHIFTING INTO NEUTRAL AND BACK INTO DRIVE. THIS DID NOT RESTORE THE EXPECTED ACCELERATION BEHAVIOR. TRIED TO PUT TRANSMISSION INTO MANUAL SHIFT MODE BY MOVING GEAR SHIFT LEFT OR RIGHT, BUT GEAR INDICATOR IN INSTRUMENT CLUSTER SHOWED THAT TRANSMISSION DID NOT SWITCH INTO MANUAL SHIFT MODE; IT STAYED IN FULL-AUTOMATIC MODE. PULLED OVER AND TURNED ENGINE OFF, THEN RESTARTED ENGINE. EXPECTED ACCELERATION BEHAVIOR RESTORED AFTER RESTARTING ENGINE.
