Four problems related to power steering fluid have been reported for the 2008 Buick Enclave. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Buick Enclave based on all problems reported for the 2008 Enclave.
Power steering failed out of no-where while turning at an intersection. Barely missed side-swiping a police car. Only had assist under high rpm's. (I am an adult and have had previous experience driving vehicles with no power steering, my teenage children would have not known what to do or how it feels to lose power steering, so I am thankful that this happened while I was driving the car and not them!) this was an extremely hazardous situation, and no recall? car was completely unsafe to drive. Prior to this incident the vehicle made loud whirling noises when the steering wheel was being turned. Dealership found steering rack-leaking from end seals, they flushed power steering system and power steering gear, pump, fluids replaced. $1987. 49 to make the car safe to drive again.
I was driving my Enclave and I pulled into a parking lot I lost power steering. I called on star and they said it was not something they could diagnose. Suggested I check the ps fluid. . . I did and it was just below the min line. I added fluid, it got better but I could still sense some problem. Svc shop said there was a leak, needed to replace the rack and pinion. Bringing to dealer next. I've seen several complaints/articles about pw pump problems, leaks. I have 60,200 miles. Seems like this is a big safety issue (what if I lost ps on the highway), why isn't gm doing something about it?.
Steering unit emits growling noise when turning the wheels. There is feedback thru the steering wheel. I have had the power steering fluid changed at 10,000 mile intervals and that seems to help, but the service station that changes my oil tells me that the unit needs to be replaced! he has seen the same issue on the GMC acadia and Saturn SUV as well. Also, we continue to have wet carpet on the passenger side due to the sun roof leaking.
I was driving on randall road traveling about 50 mph. I slowed to enter a right turn lane and the steering began to shudder when I moved the steering wheel. I braked aggressively and was able after much effort to maneuver the Enclave into a parking space. I phoned my husband and upon arrival found that the steering wheel would not move with the engine running. He phoned the dealer and Buick assistance. After 3 hours the car was loaded on a truck and taken to the dealer. The service person stated that the cooler line had developed a pin hole leak and lost fluid to the power steering system. I am still waiting since the steering pump was also damaged. No mention of replacing the rack and pinion (my husbands help with that term). I do not feel comfortable driving a car that the steering locks up if the power steering system fails. This could have been a fatal outcome under different circumstances because I could not steer the car. This is the third safety related problem since it was delivered December 31, 2007. The driver windshield wiper came loose (husband fixed) and the right rear strut weld failed leaking oil all over the garage floor and making the car feel loose driving it to the dealer for repairs. We have also noticed the passenger seat belt sign does not always work. I do not trust this car. The only bright spot is the dealership has been very responsive.
