I purchased my tahoe from the dealer brand new and always took it to get serviced at the same dealer. In 2015 I took it in for a check engine light and they said there was a misfire and they replaced the camshaft and machined the heads stating that the valves were leaking. Repairs cost nearly $3000. This year 2018 in march the engine light came on again. The dealer stated that there was a misfire in a cylinder the same cylinder that was mifiring 3 years prior. They said a roller on the rocker disintergrated and repairs would cost close to $6000 this is not due to anything I did the vehicle does even have 100,000 miles on it. No harsh driving or anything like that. I believe this is a manufacturing issue. Not a safety issue but I think it is a manufacturing defect.

My 2008 chevy tahoe ltz electrical system would go through a series of phases either when I try to start it up during a cold day or when I am on the highway. This leads to my vehicle either not starting or while driving not being able to maintain speed because the transmission begin to slip. It can also die without warning and the "check engine light" would come on for a while and can disappear after starting up again. I have taken my vehicle to the same service adviser/manager each time I experience this problem and also called gmac to get them involved to be told that they can not duplicate this problem. When ever the codes are pulled, there could be at least 7 at a time. I called gmac went I experienced this for the fourth time and my case number was 71-1326091502 issued on 07/02/2014. Today my case number is [xxx] which was issued on 11/30/2016. I had many other number in between and custom service personnel (gmac) attempt to assist me and the results in the past has been the same each time. However, my vehicle continue to be unsafe. I feel that no one really care but are going through the phases to say that they have done all they can do. My vehicle started to give me this problem at about 107,000 miles, right after my 100,000 mile bumper-to-bumper warranty expired which cost about $2400.00. My vehicle also have a total of about nine plus (problem more) months in the shop at the chevrolet dealership over time where I purchased this vehicle with no results at the end of each trip but it was taken back for the same thing each time. I feel as if every one is just coving themselves by mouth work whether than by actions. All I know is that this vehicle seem to be a "lemon" and no one has the courage to say so. My vehicle is at al serra chevrolet north, colorado springs, co. 80920. There # is [xxx]. My # is [xxx]. Thanks for your time.

I bought my 2008 chevrolet tahoe brand new. People laugh at me because I've always dealt with the dealership on everything including all oil changes. Now I'm being told that I have lifter and cam problems. I complained about the engine light being on 5 months prior to be told this. I was informed that the check engine light was on because of the tps sticking. I'm a single mother of 2. I purchased a new vehicle not to have these kind of problems especially since I've always taken my truck to the dealership. I cant afford a new engine, my truck is parked and I have to get rides to work from co-workers. I cant sleep nor work.

Check engine light began flashing, check stabilitrak light came on, engine sputtered. This was first of 4 incidents from oil consumption issue gm has with this engine. They didn't recall the engine, but had a protocol - a series of bandaids that shops used to repair or prolong. Ultimate step is engine rebuild/replacement, which gm did under warranty for those "in the know." my dealership in small town hamilton, oh, rose chevrolet, was dropped by gm and is now independent. Neither rose or gm informed me of this ongoing problem. After spending more than $9-- out of my own pocket, the car now needs pistons and rings, for another $3000. Again, gm knew of this issue and didn't inform me of it. Had I know about it, and the magnitude, I would have insisted on repair or replacement while under warranty. I'm a sales rep and drive a lot. The car now has 146,000 miles and I have a case number with gm. They should pay for the repair, reimburse me for my out of pocket and/or repurchase the vehicle from me.
