1 Adaptive Cruise Control problem

Failure Date: 10/12/2024

Check engine light came on while idling. "eyesight" tech turned off along with certain associated safety features. Next day, vehicle struggled to ignite. Came to a complete stop at an intersection, released brake, stepped on gas, and the car rolled forward as if in neutral and bucked up and down like a rodeo bull.

2 Adaptive Cruise Control problem

Failure Date: 09/18/2023

Check engine light came on while driving. All advanced driver assistance systems were disabled. Code is p26a3: thermo control valve is faulty. This is a known problem and Subaru has addressed it by redesigning the thermo control valve in 2021. Unfortunately there is no recall on the models fitted with the prior design that have a high rate of failure.

3 Adaptive Cruise Control problem

Failure Date: 11/06/2022

My brand new Subaru ignited in the engine compartment, burst into flames and exploded while I was driving it.

4 Adaptive Cruise Control problem

Failure Date: 05/04/2021

My vehicle is equipped with eyesight, which is a Subaru technology that includes adaptive cruise control, forward collison warning/breaking, lane departure warning, rear automatic braking, etc. Subaru claims that windshield replacements must use Subaru glass due the optical clarity of the windshield and that the eyesight system must be recalibrated. This is a $1339 cost (via safelight) to replace the windsheild. I have 8400 miles on my vehicle, and I am getting ready to have the second windshield put on the car. The glass simply breaks to easily. First incident, a rock hit the windshield and it cracked about inches while traveling through albuquerque, nm on I-25. Second incident happened today on I-25 with a barely perceptible sound, and the windshield has a crack about 6. 6 inches long. I am not sure what the issue is with Subaru windshields, but looking in owner forums, it's a pretty common occurrence. The fact that I am averaging a new windshield every 4200 miles is ridiculous. I have been driving for 35+ years and have had to replace a windshield less than three times. With the Subaru, I am doing it almost every 4-5 months (so far).

5 Adaptive Cruise Control problem

Failure Date: 04/26/2021

The lane keeping feature will randomly cause the vehicle to veer towards the center line at a variety of speeds and under a variety of conditions, requiring immediate driver correction to avoid crossing the center line. No accident has occurred but the system is now deactivated. In addition, the collision avoidance system does not reliably acquire a vehicle ahead if that vehicle is stopped and the speed differential is >30-40 mph. Without driver manual braking, a crash would occur. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.
