After a transmission replacement performed by Bud Clary Chevrolet, Inc. in Longview, WA on September 9, 2025, my vehicle was returned to me with critical components left unsecured. On November 19, 2025, an independent mechanic discovered loose suspension bolts connecting the ball joints to the spindles on both front wheels. On November 29, 2025, Subaru of Portland documented additional unsecured and unattached components related to the prior transmission replacement, including loose mounting hardware and a disconnected PCV hose. Subaru of Portland’s written inspection states that the loose bolts would have been unsafe if left uncorrected. These conditions were present after a major repair and created a potential safety hazard while the vehicle was being driven. This complaint concerns an unsafe condition caused by improper workmanship during a vehicle repair.

A transmission that was replaced in July of 2023 went bad un December of 2024 and dealership won't give reasons why transmission went bad or what caused a almost brand new transmission with less than 50,000 miles on it went bad. They are demanding we pay $5000.00 dollars on a transmission that was replaced under the extended warranty on cvt transmission from subaru. Which also extends to the brand new transmission. They are demanding their loaner car back and refusing to honor extended warranty on new transmission which the gave us which is bad. They will not give us anything other than it is bad. No information what so ever is being given to my husband or I as to why, how or what happened. My car will not move unless it is pushed by someone. They are refusing to honor their recall warranty or provide a loaner while dealing with their corporate offices on this issue. This is after in the past 1 and a half years my car has been in their shop for well over 8 months and I am still making payments on this vehicle. They will not even provide paperwork on the issues with my vehicle.

The continuously variable transmission failed at 114,000 miles. The unexpected lack of proper shifting on the roadway causes impediment to traffic expecting a continual flow of traffic. This causes the vehicle and drivers sharing the rode to have to make sudden braking or lane shifts without sufficient notice. The CVT was inspected by the dealer. There were no warning lamps or symptoms prior to failure.

Received subaru recall (wuj-95) on aug,3.2020 pertaining to exhaust pipe bellow failure. The recall includes replacement of the exhaust y-pipe that is installed from engine to tale pipe. This exhaust pipe in my understanding was installed under a stress manufacturing process where the pipe and fastener system has to be forced in to install. This puts excess stress on the bellows and caused failure. My question is why did subaru wait five years to notify the consumer and issue a recall. Please return my request for a full explanation of what happened. 2nd. I would like to address the CVT transmission issue. Subaru extended the transmission failure time line to 10yr-100,000 mile. I am having many issues with my CVT transmission and subaru will not issue a recall. With all the complaints and problems with the gen-5 CVT transmission would please take a 2nd look at this issue.

Transmission failure. It is a known issue with models with their original CVT transmission, but rather than issue a recall, they're extending warranties and fixing as they break. This left me with no power on a state highway that had speed limits of 75mph. I managed to make it to the shoulder to be stranded for an hour waiting for a tow truck. This is extremely unsafe and if it's a known issue, I'm not sure why they're not preventing these scenarios. I was going about 70mph in the center lane of a 3 lane highway when suddenly my car jerked and then wouldnt accelerate.
