2009 Volkswagen EOS Problems

What owners report

Owners of the 2009 Eos most often describe transmission trouble: the direct-shift gearbox jerks, hesitates, flashes its gear indicator, drops into neutral on its own, and in some cases needs replacement, with many reports mentioning an extended warranty or a recall that owners say was not honored for their car. ABS and stability-control warning lights are the next most common theme, frequently tied to a fault in the ABS/ESC control unit, and a smaller group of reports covers engine timing chain tensioner failure and oil leaks. Reported mileages range from a few thousand to well past 150,000, so problems appear at both ends of the car's life.

1. 1
   Transmission and drivetrain

   DSG transmission jerks, hesitates or drops into neutral

   • 32 complaints (38%)
   • median 70,000 mi at 7.2 yrs old (29 state mileage)
   • filed 2008–2025

   Complaints describe harsh or jerky shifting at low speed, hesitation or a short lag when pulling away, and occasional abrupt clunking between drive and reverse. In many reports the PRNDS gear indicator flashes, engine rpm rises without the car moving, and the car slips into neutral; owners say switching the ignition off and restarting sometimes restores drive. Dealers commonly diagnosed transmission or mechatronic unit failure and quoted replacements, while several owners say the DSG extended warranty or a related recall was refused for their vehicle. Reported from a few hundred miles up to about 180,000 miles, with many reports around 50,000-120,000 miles, often at low speeds or when shifting between drive and reverse.

   Recall 09V3330003 related service bulletins

   What to check: Ask whether the DSG has had its scheduled fluid services and whether any mechatronic unit or clutch pack work was done, and request service records. On a test drive, note any shudder or delay when pulling away from a stop or shifting into reverse.

   “At times, the vehicle will not go into reverse. The gear display blinks and the vehicle must be shut off before being able to eventually go in reverse. I brought the vehicle into a Volkswagen service center and was informed of the extended warranty regarding the dsg. However, Volkswagen has informed me that since I did not have the dsg serviced at 40,000 miles, it would not honor the extended warranty. …”

   “August 2013: 2009 vw EOS abruptly lost power, would not accelerate, and the dashboard (prnd) flashed erratically; happened numerous times since. A vw master mechanic of 14 years told me that the dsg temperature sensor should be repaired and mechatronics unit should also be replaced. He advised I take the vehicle to a dealer for the recall/warranty repairs. Prestige vw, turnersville, nj told to replace the transmission (5700 dollars), due to internal transmission issues . …”

   Brakes

   ABS and stability-control warning lights

   • 34 complaints (40%)
   • median 68,000 mi at 8.4 yrs old (26 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2009–2025

   Owners report the ABS, stability-control, brake and sometimes engine or speedometer warnings lighting up together, occasionally with the speedometer dropping or the horn stopping. Several say diagnostics pointed to a failed ABS control unit or an implausible ESP signal, and some describe the brakes hesitating or the pedal responding poorly during the episode. Complaints often mention recall 16V913000; some owners say the remedy was applied or denied, or that parts were unavailable, and others were quoted substantial repair estimates. Mostly reported between roughly 20,000 and 120,000 miles, often while driving at normal road speeds or shortly after starting the car.

   Recall 16V913000

   What to check: Check that recall 16V913000 was completed for the specific car and ask for documentation; note whether any ABS warning light stays on after start-up. A scan tool check of stored ABS/ESP codes before purchase is worthwhile.

   “My 2009 EOS is under recall for the ABS system malfunctioning. I was never informed about this. I replaced my brakes as one mechanic thought because the ABS brake light went on - that was needed. The ABS light still stayed on. Last week the ABS light and and engine light and brake light went on and my car lost power and control on a busy highway at night leaving me on the side of the rode in danger and had to call aaa. …”

   NHTSA complaint #11051636, filed 2017-12, 66,000 miles

   “Abs, engine fault, and a whole cluster of lights came on suddenly when the brake was applied at a normal rate of speed (~40mph), with the wheels almost locking up (until brake was released). This caused a potentially extremely dangerous situation, and could have been much worse if there were cars in the next lane, which I had to quickly switch into, to avoid an abrupt braking by the car in front of me. This appears to be a common problem in these 2009 vw models, and we feel should be investigated further.”

   Oil leaks and rough running / loss of power

   Mentioned in 7 of 60 sampled complaints

   Owners describe recurring oil leaks that persisted after multiple repair attempts, and other complaints describe the car hesitating, running rough, refusing to accelerate, or losing power at speed with a fuel odor. In these reports dealers often could not reproduce or identify the cause, and parts such as the throttle body, coil pack or injectors were replaced without resolving the problem. Reported from about 34,000 miles up to 150,000 miles, often during highway driving or after repeated cold starts.

   5 related service bulletins

   What to check: Look under the car for fresh oil residue and check the oil level and condition; ask whether oil consumption has been measured and whether any fuel odor or misfire codes were diagnosed.

   “First thing to go on this car was the clutch pack could hear clanking noise when I was slowing down...had to replace.. Next came the failed injector..I was driving the car smoke started coming out of the engine and the exchushed pipe car almost caught on fire fuel had leaded all over my engine ..now the ABS unit needs to be repaired they want $2,600.00.. ..my car has 34,000.00 miles on it...the inside of my doors are peeling...they want another $1,000.00 for that ! ..&the roof gets stuck half way when its really hot!”

   “I was driving home from baltimore on the freeway going about 70mph and the vehicle started losing speed and nothing I did would get it to go again. I had to pull over put the car in park, shut the car off and then I was able to go again. This happened about 6 more times driving home to pittsburgh. I went to the dealer and they fixed it . It worked for a short period of time. Then it happened again and they couldn't find anything wrong with it so they put seafoam in my car. It happened several more times and they had my car for months. …”

   Timing chain tensioner failure

   • 5 complaints (6%)
   • median 85,000 mi at 9.0 yrs old (5 state mileage, few)
   • filed 2017–2019

   Complaints describe the engine making an unusual noise and losing power, or failing to start, with diagnosis pointing to a failed timing chain tensioner; in several reports the chain and tensioner came apart and valves struck the pistons, requiring engine replacement or major repair. Owners say the older tensioner design was superseded and that repair bills were significant, with the work sometimes done preemptively after a shop identified the old part. Usually reported between about 80,000 and 180,000 miles, though some complaints describe the failure happening with the car in motion or on start-up.

   2 related service bulletins

   What to check: Ask whether the timing chain tensioner has been updated or replaced and keep receipts; a pre-purchase inspection that listens for chain rattle on cold start is a sensible step.

   “Timing chain tensioner system failure I'm reaching out in regards to legal advice regarding timing chain tensioner system failure on my 2009 Volkswagen EOS. While traveling with my two young sons for their spring break, my car completely failed (while in-motion), putting both my life and the lives of my two children in harm's way. …”

   “My wife was turning into a parking lot when the engine suddenly made a noise and lost forward power. She was stuck in the middle of an intersection and could have been killed! We spoke to our mechanic and he diagnosed the problem as a failed timing chain tensioner. This caused the engine valves to impact the pistons and caused catastrophic engine damage. We paid $2706.25 to buy a used engine and $1500 in labor for the installation. …”

Buying note. A 2009 Eos is worth considering only with a documented service history: confirm the DSG fluid services were done, check whether recall 16V913000 was completed, and ask about the timing chain tensioner. A pre-purchase inspection that scans for transmission and ABS codes, checks for oil leaks and water intrusion, and cycles the roof is the most useful money spent.
