2008 Buick Enclave: harsh or hard shifting

Filed Mar 18, 2020 · Brakes, Engine · 93,500 miles · PA

Steering makes a clicking noise when turning the wheel. The vehicle makes a clunking noise when hitting minor bumps in the road and intermittently the steering wheel shakes at highway speeds. The vehicle has a rattling noise when first started and recently the ABS/traction control service light comes on when first started. Also the vehicle has decreased horsepower and the mileage lcd screen has been acting up and not always showing the prndl and also the transmission acts up when shifting into 3 and 6 gear

Driving at interstate speeds with cruise control on, set to 80mph. After hitting a ridge at edge at edge of bridge, the vehicle suddenly shuttered causing vehicle to automatically shut off cruise control and decelerate quickly. I went from going 80mph to 55mph in a short amount of time. After touching the gas to try to maintain speeds, car suddenly shifts into a neutral position pushing engine to red-line, then shift into 5th gear roughly. The vehicle from this point on, had issues shifting into 3rd and 5th gears. This car had absolutely no prior issues with the transmission prior to this date. I had the car serviced and completely checked out by a mechanic for any mechanical issues a few days prior to this trip. I took it to the dealer, who fixed two separate transmission plates and replaced the transmission module. I was guaranteed by the repair shop manager that I would have no further issues with the transmission. Little did I know, I should have gotten that conversation in writing. I continued to have hard shifts after the repair, only to be told that's the transmission module sensing how I drove. Less than one week later, transmission completely failed, leaving my wife stranded on the side of the road with the vehicle unable to not shift out of 1st gear, forcing me to call a tow truck to bring it to back to the dealership. Now they are telling me I have to replaced the entire transmission, all at my cost. After paying for the plates and module to be replaced less than a week prior, now they want to again replaced those parts with a completely new transmission. If I were being followed too closely by another car or semi on the interstate, I would have been rear-ended. If that were the case- there wouldn't be a complaint, but a lawsuit. Get this transmission issue fixed. I have read countless stories of the same exact problem.

The wave plates broke while driving 60mph on the hwy. Car jolted and clunked...felt as if we went from 5th to 1st gear. Took vehicle to dealership and found it was the wave plates. Talked to gm - gm district manager [xxx] admitted that gm had an issue with certain models with the wave plates due to them not being heat treated properly. Got this all on recording too. Could have caused a nasty accident. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

2008 enclave developed a clunking noise when turning a slow speeds. Took to dealer who says it needs a new rack and struts. Car had been totally serviced in july with no issues seen. I have seen many reports of these parts failing on this model year.

My car has been maintained the whole time I've had it. I've had to have replaced the motor for the electric seat, the hinge mounts for the lift gate, the dvd player, and an oil leak fixed. Now the 3/5/r wave plate has broken. What's up with the buick enclaves? They cost too much for all these items to break and need replacing. I could understand if the SUV was abused and not maintained. If I wanted to have my car in the shop all the time, I would have bought a clunker. Why doesn't gmc have a recall for some of these items, especially the transmission 3/5/r wave plate. It isn't safe when it goes out and you are on the road. I have grandchildren that I drive around in this SUV. We could be killed. Gmc needs to wake up before someone is killed in regards to this problem.

About 3 weeks prior I noticed very subtle clunk when changing gears. Than out of no were the car started slipping gears at around 40mph. The engine would rev high RPM but it wouldn't kick into 5th gear. Only did the it once. Within 1 day it slipped every time 5th gear was engaging, within 2 day of that 3rd gear was slipping every time. Brought it to aamco and was informed of a r/3/5 wave plate clutch disc tsb with this model transmission. Transmission needs a rebuilt to the tune of $2000-2500. Pathetic that a $45k vehicle cant even make to 100k miles. Who says china makes all the crap? Gm must employee the chinese.

Within the last four months, I have noticed a vibrating noise as part of my steering. My major complaint is a very loud sharp whistling noise coming from my engine after driving it for a short time. The screeching, whistling continues while it is idling for long periods of time. I am concerned of what it is and also find it not acceptable to have to put up with the noise constantly, especially being only 2 yrs. 4 mo. Old and less that 25,000 miles. Obviously it is a defect by gm and they are responsible for fixing it asap as I'm not sure if the noise is all there is to it as far as safety. The technicians at the dealership worked on it, put in a new defibulator, took it back out and said they called gmc. According to the technician, gm said all enclaves make the same noise. I am irate as not one on the lot makes the noise nor do any other's that I know people drive. I did not pay close to $40,000 for a luxury vehicle that sounds like a 15 year old clunker in which again is embarrassing as well needs to be reckoned with before my next description may be a big safety issue too! .................. Take care of your consumers gmc as integrity should be #1 in your company.
