My Temp control sensor is causing my check engine light to come on. After reviewing the problem, It seems many owners have had this same problem nation wide. I,m simply adding to the complaints by other owners that this should be a recall problem since so many owners are having this same problem. I,ve only had this car for 2 weeks & like the vehicle very much but this is a per the mechanic that may be caused by the sensor being placed too close to the exhaust without better protection from the heat. Please take this into consideration & hopefully come up with an adequate protective cover
On 9/24/23, I was driving both locally & the highway in S. I., NY. Suddenly the Adaptive Cruise Control feature shut off & on repeatedly & kept flashing (Adaptive Cruise Control unavailable) almost causing an accident, then I pulled over and shut off the system. The next day on (9/25/23) I brought the car to GMC & Buick Dealership at 1855 Hylan Blvd, S.I. N.Y. 10306. After a couple of hours, the manager Carlos Mercado tells me they need to do further testing tells me to come back on 10/04/23. I arrive at 9:00am for my appt. After three hours, I asked him what’s going on? He tells me that there are two Modular’s in the vehicle & needs to be reprogramed & updated. He says the mechanic that was working on it can’t do it & to come back. I knew at that point I was being scammed. On 10/11/23 at 10:15am he comes & tells me the vehicle is ready. I go to the register tells me at first was $671.00. I said for what? It’s outrageous! He says oh it’s electrical. I asked him did you replace any parts? He says no. replace any wires? He says no. I said if this was a recall I wouldn’t pay for it because its a safety issue. So he must have felt guilty and says I give you a discount & the price now is $555.56. So I says to him this is a lot of money for this. He tells me it was labor. I said to him I have been watching the whole time that the vehicle would sometimes be in the service area & the parking lot with the mechanic hardly working on it. I said to him do you think I’m a fool because I’m a woman unaccompanied by a man you take advantage of me. So they would not release the car unless I pay for it which I did with a credit card. On 10/12/23, I filed a complained with GM for a full refund, and explained that the program was faulty & only need an update and I was contacted by Charlie from the Executive team on 10/17/23. Tells me he will reach out to the dealer. On 10/23/23 he tells me they can only offer $250 in reward points which I declined, because they know I wont use it.
Unnecessary safety feature sounds and alerts distract driver's normal driving and viewing habits. Any which could be turned off, have been. Every time the car is started, there is a message that these warnings have been turned off. The message never goes away and stays on the entire drive time unless manually turned off.] These type of messages need to turn off after a short delay.
