Recall Number 19V855000
Recall Date 12/02/2019
Component
POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM, PCM)
Summary
Subaru of America, Inc. (Subaru) is recalling certain 2019 Ascent vehicles. The transmission hydraulic sensor may inaccurately measure the hydraulic fluid pressure.
Consequence
If the fluid pressure is measured higher than its actual value, the hydraulic pressure will be reduced. If this occurs, the transmission drive chain may not have the proper tension, resulting in a loss of drive power and an increased risk of a crash.
What Owners Should Do
Subaru will notify owners, and dealers will reprogram the transmission control unit. The hydraulic sensor harness will be replaced on vehicles with certain stored diagnostic trouble codes. In addition, any vehicle confirmed to have experienced low drive chain tension will have the transmission assembly will be replaced. All repairs will be free of charge. The recall began January 31, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUV-07.
'The vehicle was shifting with a bouncy feeling, like it had issues with the chains? This is my first CVT so I’m not familiar with their internals. Uphill with a load makes the trans really bounce between gears. It didn’t feel like a manual with a slipping clutch.'
Not at all like Subaru reached out to him...They may or may not fix it depending on whether or not you call them, no vin numbers or mfg. dates provided...seedy underhanded company IMO, avoid.
