50mph limit 1st 500 miles of towing??????
Hello,
Have a new '19 Tahoe LS, just turned over 600 miles. Test-pulling my small RV today, only about 3200 pounds GVW, checked the manual. Manual says to limit top speed to FIFTY MILES PER HOUR for the first 500 miles!!!! Seems excessively on the cautious side to me??? And, on that run, I'll be hauling in February 550 miles, departing The Frozen North in no doubt sub-zero temps. Fact is, there is not enough daylight to travel 550 miles at 50 mph that time of year, and driving at night is not a good thing for me anymore. I normally haul the trailer at 62-65 mph. I really don't want to haul the trailer around for nothing except to meet the miles requirement between now and February. Thoughts on this?? I don't want to void the warranty, and the Tahoe has a black box, no doubt would flag this. |
I do what they recommend.
what is a black box? Is this an aftermarket device? I worked for gm 5 years ago and at that time we had no way of recalling your driving conditions for 500miles. Today at fca we install data recorders to help in repairing intermittent problems. this device can only store 2minutes of data. it would need a big memory to store 6 hours of driving. |

I received an email shortly after taking delivery that said I was accelerating and braking hard, and I might be more gentle for better mileage and wear.... So.. figured the source was the event recorder... Maybe it's from OnStar??? From the Manual: Event Data Recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: . How various systems in your vehicle were operating; . Whether or not the driver and passenger safety belts were buckled/fastened; . How far (if at all) the driver was depressing the accelerator and/ or brake pedal; and, . How fast the vehicle was traveling. 434 Customer Information These data can help provide a better understanding of the circumstances in which crashes and injuries occur. Note EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR. GM will not access these data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request by police or similar government office; as part of GM's defense of litigation through the discovery process; or, as required by law. Data that GM collects or receives may also be used for GM research needs or may be made available to others for research purposes, where a need is shown and the data is not tied to a specific vehicle or vehicle owner. |
That was most likely Onstar.
You said you already passed the 500 mi threshold, so what's the issue? |

You said you already passed the 500 mi threshold, so what's the issue? I found that odd too, I'll have close to 3000 miles on the 'Hoe by then, so I think I'll keep it below 60 for a while... Trailer is only 3200 pounds, vehicle is rated 8400... |
I didn't see a towing section in the manual. Just this:
https://cimg8.ibsrv.net/gimg/chevrol...0458beb664.gif https://cimg3.ibsrv.net/gimg/chevrol...695e90710b.png It does not say "first 500 miles of towing". It says 500 miles (period). This is typical for all vehicles. It also says "DO NOT TOW DURING THE BREAK-IN". |
From my manual: (.pdf version downloaded from mychevrolet ), Page 278
When towing a trailer: . Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state. . State laws may require the use of extended side view mirrors. Even if not required, you should install extended side view mirrors if your visibility is limited or restricted while towing. . Do not tow a trailer during the first 800 km (500 mi) of vehicle use to prevent damage to the engine, axle, or other parts. . During the first 800 km (500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. . Vehicles can tow in D (Drive). Tow/Haul Mode is recommended for heavier trailers. See Tow/ Haul Mode 0 238. If the transmission downshifts too often, a lower gear may be selected using Manual Mode. See Manual Mode 0 236. |
