Two problems related to clutch broken have been reported for the 2013 Volkswagen Jetta. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2013 Volkswagen Jetta based on all problems reported for the 2013 Jetta.
During normal around-town operation the vehicle (2013 Jetta hybrid) experienced a temporary loss of drive power. It felt like the clutch slipped or became disengaged momentarily (3 seconds). The check engine light displayed. We immediately drove it to a repair shop that was less than a mile away. After reading out a diagnostic error code (p0841 - transmission fluid pressure) and noting that the transmission fluid was dark and contaminated with a burnt smell, the initial shop decided the repair was beyond their ability as it seemed to be related to the transmission pressure sensor switch which is embedded inside the transmission case under 600 psi pressure. The car was driven without incidence a few miles (5) to the local dealer, where further diagnostics took place. They uncovered 2 additional error codes (p1806- function restriction due to pressure drop) and (p17713 - clutch tolerance). After a few days of internal debate at vw (I believe they contacted the chief engineer or guru for that particular unit), the dealer came back with the prognosis that the entire transmission needs replacement at the cost of about $9000. In the weeks previous to this episode, we had noticed what felt like a mild slipping of the clutch, but never a full loss of power and no check-engine light. The problems we are experiencing sound identical to those reported in NHTSA safety recall 19v866000 (vw's number for this recall is 34j6), which states �hairline cracks can develop within the transmission electronic gearbox (mechatronic unit), causing an internal transmission oil leak and a decrease in oil pressure. A decrease in transmission oil pressure can cause the clutch to fail to engage, resulting in a sudden loss of drive power, increasing the risk of a crash. � it seems to me that the current recall perhaps needs to be more inclusive. This car is 8 years old, but only has 47k miles.
Regarding recall 19v866, the failed part, mechatronics unit, causes low transmission oil and clutch slippage both of which can cause damage to the vehicle transmission. I was told by vw customer care that my car would be safe to drive while waiting for the repair. Now, both my mechatronics unit and transmission have gone out. Vw refuses to provide me any specific details on the transmission failure. They say, "it's an internal failure", "its unrelated to the mechatronics", and "we can't tell you exactly what is wrong with your transmission". They have also said that they will not repair the mechatronics unit without me repairing the transmission because the mechatronics unit would be damaged by the now damaged transmission. The mechatronics system controls the transmission directly and has been mis programmed for the life of my vehicle. This incorrect programming has caused the mechatronics to cause physical damage to the clutch plates in the form of cracks. The cracks allow transmission oil to get trapped where it is not supposed to be and leave the transmission low on transmission oil, though there are no outward error codes until the car starts to have problems with shifting. That means my car has gone 162000 miles and the transmission has been low on transmission oil unbeknownst to me, the driver of the vehicle, for an unknown amount of time. Over 1000s of miles, it has likely damaged my transmission. Additionally, the damaged clutch plates can fail to engage or slip. This can also cause damage to the transmission. Not to mention that the clutch plates are directly connected to shifting, and if they are being physically damaged by the mis programming, I don't know what this has done to my transmission. At this time, vw has refused to repair my vehicle for the recall or look into possible damage to my transmission.
